A solid high-power amplifier does more than make the sound you love louder. A well-built power amp cleans up sound quality, improves bass response and delivers the right amount of power to efficiently drive multiple speakers in distributed audio system or home theater. Our AMP300 is a flagship amp that sells well for a reason. This 350-Watt A/B two-channel dual source amplifier is ideal for use as a remote amplifier to power your whole house audio system or as a single amp for a dedicated home theater or media room, and you won’t find an amp with the same features that we pack in at such an affordable price. It is stable at 2 ohm load.

Dual Source Switching

The AMP300 also includes dual source switching to connect two audio sources and toggle between them for greater listening flexibility. Automatic source switching switches between connected sources with a priority signal-sensing feature, so if a DVD player is connected to input 2, then you decide to stream a movie through a game console, when the console is turned on, the AMP300 automatically switches to that source. The AMP300 also includes a variable delay control that lets you adjust the amount of time needed to "listen" for a signal from your main input, between 3 and 15 seconds. This prevents gaps between music tracks from accidentally switching your inputs. This high power amplifier includes two RCA signal level inputs so with the addition of an RCA-to-mini stereo cable (sold separately), you can connect your smartphone or other device.

Plenty of Power for the Price Pair our AMP300 with the power-hungry speakers, and the sound quality will transform your listening experience. Rated at 350 Watts per channel peak power (470 Watts Bridged Mono into 8 ohms), the AMP300 can be configured as bridged or stereo. In bridged mode, you can combine the left and right channels into one audio channel which bumps up the power to a whopping 470 Watts (8 ohms). When playing dual sources, switch to stereo mode which reduces the power to 350 Watts per channel. It is the only high current 2 ohm load stable amp in the market.

Price-defying Features

The AMP 300 also includes two sets of speaker outputs with front panel controls, auto-on signal sensing or 12-volt trigger, rear panel master level controls, dual line-level inputs with priority override switching and dual voltage of 110V/220V and auto signal sensing. This amp has a clean, brushed metal front panel with a volume control, power on and off button and a balance control knob to adjust the balance between the left and right channels and dial in just the right sound level mix. Built-in, illuminated dual voltage meters allow you to monitor the volume level readings, while special protection circuitry safeguards the amp from a short circuit.


Other Product Info

The AMP300 (MI6) is an excellent power amplifier for pro-installation applications. It is a high current (2 Ohm Stable) two channel power amplifier, which is overload stable. It is ideal for use as a remote amplifier, or as a single or dual zone amplifier. It's the perfect heavy duty, high fidelity amp for powering your whole house audio system! With a stylish, built-in voltage meter, it can can produce some serious power to drive your whole house audio speakers! Weight is 40lbs. Feature

Hi Ruby: The AMP 300 will be effective driving 8 external zones. The AMP 300 features both Hi and low level input. Your Yamaha Receiver really only has High (speaker) Level output so no Low Level Pre Amp output. The High level input reduces the input back to a low level pre amplified signal that is re amplifier inside the AMP300 Audio Section. In order to connect you would connect speaker wire from the Yamaha Speaker A Right and Left (+/-) to the Speaker in on the AMP300. You will need to make sure to connect the switch above to Line 2 (push to the right). The DMP8 would then connect to the Speaker A output of the AMP300. The Yamaha will then be a Pre Amplifier with all the connections you will need. It has four analog inputs and two digital inputs. Plus you will need to hard wire a network cable into the LAN connection. Please let me know if you need additional help; TL/4561

I want to run 2xOMSUB200 with 8xLS3 using a Sonos Connect. How would I wire up the speakers to this AMP? Will the Amp automatically switch on/off when I turn my Sonos on?
2 Answers
Hi IMS: I would connect your two OM Sub 200 in parallel to speaker A output from the AMP300.So with a four conductor cable like our CL14/4 wire both subs together R+, R-, L+ & L-. So you have 2 wires connected to each one of the four outputs. Next you will want to wire the 8 each (or four pair of LS3) in series parallel. Four speakers for the right and four speakers for the left. This will take a little patience and CL14/2 speaker wire. Contact me at so I can furnish you a diagram. Good system... TL/4461

Note, regarding your second question the AMP300 features three turn on options: 1) Manual, using the on/off switch on the front panel 2) Connecting a 12 volt trigger to your other component like a receiver. 3) Auto Sensing, goes into stand by after 5 minutes once there is no signal. Then comes back on instantly once it sees a new signal. Note: in all cases the power switch on the front must be in the on position. TL

Will this amp push my Cerwin Vega VS 150s ? I need more bass! My denon pma 920 isn't cutting it.
1 Answers
Hi Mike: All the reviews on the Cerwin Vega points out that you need a true power amplifier not a Receiver. The AMP 300 is a True High Current Amplifier that when you are driving a 4 ohm like like the Cerwin Vegas are rated at, you will nearly double your current demand so you are looking at the AMP delivering 200 plus watts per channel and plenty of head room.

If I want to run 8 (pairs) of speakers with this amp and a speaker selector how do you connect the speaker selector to the Amp? Do you use speaker A and speaker B output from amp?
1 Answers
Hi Ryan: Yes, this amplifier will work for your application. You will have two options for Speaker Selectors. Option one we recommend the TSM-8 Speaker Selector that features internal Auto-Former's for speaker protection switch on the back panel. This has the best internal protection and power output when using the protection and not planning on using Impedance Matching Volume Controls for each room/zone. The second option would be to use our DSM-8 speaker selector that we would recommend using with Impedance Matching Volume Controls, one for each pair of speakers per zone. The DSM and ISS speaker selectors feature internal resistors which when enabled cuts the power handling in half (140 W down to 70 W for both the DSM-8 and ISS-8 models). So it is recommended using Impedance Matching Volume Controls to do the Heavy lifting (protection) and disable the protection on the Speaker Selector so it would be rated at 140 Watts. Checkout either the SVC-300 or VC-105 (featuring on/off switch) Impedance Matching Volume Controls Either way when you use the Speaker Selector you connect it to Speaker A only of the AMP300. TL/3893

Hi, I want to power two OM-SUB200 and four AP-525 speakers. Which amp is best suited to power the system???
1 Answers
Hi Pedro: The AMP-300 will do a great job. You would connect speaker A of the AMP-300 directly to the first OM-SUB200 four conductor inputs (R&L, +/-) then connect a pair of the AP-525 to the four conductor output (R&L, +/-) of the OM-SUB200. Then repeat the setup with the second OM-SUB200 and AP-525 to Speaker B of the AMP300. You will be able to play Speaker A or Speaker B or both Speaker A and B at the same time. It also makes it easier to run a four conductor cable like our CL3/FT4 14/4 (direct burial) from the Amplifier to the OM-SUB200. Then run 2 conductor 14/2 to each AP-525. Also check out our Aqua Blue Waterproof wire nut connectors for terminating the Speaker Wire to and from the OM-SUB-200. This amplifier is also multi Voltage where it can be plugged into either 115V or 230V. The AMP200 would also work for your application. It features the same design but a little less power.

Can you use the left output as a mono signal for LFE for a separate sub woofer amp? Also does anyone know what the delay level switch is for?
1 Answers
Hi Vincent: The output from the AMP300 is not a true LFE (low Frequency Effects). I believe you can only get that output from a AVR Receiver with dedicated LFE output. The LFE by passes the controls of a dedicated sub woofer amplifier. Most AVR output a mono low frequency signal. The Delay switch; this has to do with the time when you turn line 1 off and Line 2 comes on. It adjusts between 3 and 15 seconds. The problem is when you listen to line 1 and there is an extended silent passage the automatic source switcher will think line one has turned off and will now switch over to line 2 but as soon as the silent passage is over it automatically switches back to Line 1. The Automatic Source Switching is found on our lower end amps like the AMP120 and XMP100. The delay is less than 5 seconds and there can be issues with it switching prematurely to line 2. We added the adjustable delay to our AMP200 and AMP300 as an upgrade allowing you to set the delay up to 15 seconds. We typically recommend connecting to Line 2 input when connecting only a single source. Plus Line 2 output only pertains to whatever is connected to Line 2 input. It does not work with Line 1 input. So when you talk about connecting your sub amp it will only work for whatever is connected to Line 2 input. TL/4537

Will this amp work well with my DTR 40.6 receiver with 7.1 surround and how should I connect the speakers.
1 Answers
HI Keith: It depends on if you are using your Integra as a Surround Sound Receiver and you want to add a second zone out put to control multiple zones connecting to the ZONE 2 Pre amp output. If this is the case you would connect the Zone 2 output to the Input#2 of the AMP300. That if you are using all 7 powered channels for your Home Theater and you want to power a Zone 2 with the Zone 2 Pre amp outputs. You can connect two speakers directly to the AMP300 (Speaker A/B) and have two zones.

I would like to power four pairs of in-ceiling speakers with the AMP300. Our house came wired so that there are volume control knobs in each of the four rooms with speakers. Do I need to purchase a speaker selector like the DSM4? Or could I just wire the four pairs of speakers directly into the two sets of speaker outputs on the back of the AMP300? (I.e. plug two wires into each of the speaker outputs in the back of the AMP300). Thank you!
1 Answers
HI Dan: The Speaker Selector adds more control and in some cases handles the protection of the Amplifier. It gives you the ability to turn each zone on or off as well. It usually is connecting all the wires in Parallel. In your case where you have volume controls you will need to determine if they are impedance Matching controls where they have an impedance switch (typically with settings of 1x, 2x, 4x and 8x). Four rooms with a single pair per room would mean the impedance matching setting would be 4X. And typically the Impedance matching Volume Controls are the primary choice to handle the protection. So you will need to determine if these are Impedance matching volume controls and if so what are they set at before you go to the next step. If they are Impedance matching make sure each one of the Volume Controls are set to 4X. If the Impedance matching Volume controls are handling the protection you need to make sure the protection button is off/disabled. If you are only planning a single source than you could go with the ISS4 speaker selector to save money. TL/4301

Hi Jason: Yes, first you need to check if your receiver has a 12 volt trigger (3.5mm connection) which you would hard wire to the 12 Volt input trigger of the AMP300. The second option is to utilize the Auto on which is a music or signal sensing turn on circuit that. In this mode the amp goes into stand by mode when there is no signal present after 5 to 10 minutes. It then comes back on when the music comes back on. I hope that helps TL/ 4180

I need to power 12 sets of whole house speakers, each speaker is only 50watts. Can I use this amp for that system? Also, I have an 8 speaker selector currently, could I buy an additional 4 speaker selector and connect that to the Speaker B outputs and Run both the A and B speakers at the same time to get whole house audio??? I have impedance matching volume controls in each room location.
1 Answers
HI Mark: A great choice for your whole house audio. You can add the the four zone speaker selector to Speaker B. Make sure you set the Impedance matching Volume Controls to 4X on the four Volume Controls connected to the 4 zone speaker selector. You also need to determine how often you will listen to all zones at once. It is a good habit to turn the zones off at the Speaker Selector especial when not listening to a particular zone for any length of time. If you were to play four or less of the eight zones consistently you could also get away with setting impedance matching setting to 4X on the eight zones as well. The problem is most of the Impedance Matching Volume Controls (unless it is our VC-105 with dedicated on/off switch) do not have a shut off switch when you turn the knob beyond the audible listening of the zone through the respective Volume Control in the zone. Instead you have a Volume Control in the wall that is diverting your signal into the transformer and still active. If you show the discipline to shut off the zones when not in use the system will be much stabler. Good luck TL/4074

Hi Abel: Are you using the Infinity 1260 W Reference 12" or 1262 W? If you are using the 1260 W single voice coil I am assuming you are wiring them in Parallel and are showing a 2 ohm load to the the Amplifier or the more conservative series where you have an 8 ohm load and have cut the output of the amp in half. It sounds like you have a similar amp to the AMP300 already, what amplifier are you using (brand and model)? The AMP300 would be rated at 150 W RMS at 8 ohm and 235 RMS at 235 W. TL/4064

I want to drive 4 Speakercraft Aim 8 fives with this amp. Will this amp be sufficient? I would like to also run 2 Speakercraft boom tombs off a second AMP300 - how should those be wired?
1 Answers
Hi Maynard: The single AMP300 will work just fine for the AIM 8 five's. Connect a pair to speaker A and a pair to Speaker B. I am assuming they are rated at 8 ohm and should have no problem running in parallel. Regarding the Boomtomb (times 2) you will need a dedicated sub amplifier like our SMP250 to power the Boomtomb since it does not have an internal crossover. You can start with a single SMP250 and connect both Subs in series. Each sub is rated at 4 ohm so by connecting them in series you get an 8 ohm load. Run a two conductor cable to each sub connecting the positive (red jacket) and negative (black jacket) from you component rack. At the component rack connect one of the positive to the SMP250 red output. Then connect the black (-) conductor to the red (+) conductor of the 2 conductor cable coming from the second sub. Then connect the black (-) conductor to the black output connection of the SMP250. If this is not enough output then you will need to add a second SMP250 so each Boomtomb will have a dedicated amplifier. This would be your maximum output. You will want to connect your source to the the Input #2 of the AMP300. Source could be from a Zone 2 output of a AVR or maybe SONOS Connect. The single SMP250 would connect to the Line #2 output of the AMP300. If you add a second SMP250 you would connect to the output of the first SMP250. Plus you could easily wire the speakers since both two conductors are run to the central location I would be more than happy to supply you a wiring diagram ( if need be. Good choices TL/4048

Hi Joe: Are you planning to connect the three pair of Rock speakers directly to a single AMP300? Are you planning to use Impedance Matching Volume Controls, one of our OVC300 for each pair of Rocks? The Impedance Matching Volume Controls allow you to adjust the Impedance so the Amplifier sees 4 ohm load thus increasing the current and output power of the Amplifier. Plus the volume controls will give you more flexibility in controlling the complete system You might even consider four pair of speakers and adding another Volume Control. The AMP300 weights over 40 pounds due to large Toroidal Power Supply and ample internal Heat-sink needed to handle the High Current draw. A true Audiophile Amplifier featuring total discrete components in the Audio Output Circuit with Fully Complimentary Bi-Polar Devices mounted to the Heat-sink. I would recommend using our DSM4 Speaker Selector to organize your connections with the Amplifier featuring on/off switch and A/B dual source switch per each zone. You could even go with two AMP300 driving two pair of Rocks each, 4 ohm load. Start with a single AMP 300 and see if it is enough. Good choice TL/3845

I'd like to get more explanation about how to use the 12V Triggers for the AMP300. I would like to control the on/off for this unit with a remote control and I assume that is how the 12V Triggers work. What is the difference between a "signal sensing" and "DC Remote trigger"? Where can I find a remote control device that will work with this unit?
1 Answers
HI Joe: The 12 Volt trigger input needs to be hardwired (or physically connected) to a component like a Receiver that would feature a 12 volt trigger output so it would send a turn on or turn off signal to the AMP300. The output 12 volt trigger on the AMP300 allows you to send a turn on or turn off signal to a second AMP300 as an example. So the 12 Volt trigger has to be wired to a component that features a 12 volt trigger output. The signal sensing or auto sensing triggers the amplifier to turn on when it senses a signal on the input side from the source (the Amplifier must have the manual switch in the on position for this to work). When it fails to see a signal after 10 to 15 minutes it goes into stand-By mode waiting for the signal to return. So check the Source or Receiver you want to connect for a 12 volt trigger output or you may have to settle for the signal sensing to do the trick. Good Luck TL/3729

Hi, I already bought the AMP300 and now I'm wondering how to connect my speakers. I originally planned for 4 outdoor speakers but I will need 6 speakers to cover the area properly. What is the best way to connect the speakers given that it's all the same zone? I'm thinking of connecting them in parallel (3 on one channel and 3 on another channel) which drops the impedance to 2.67Ω. What is the best way to acheive that? Using the bridged connections for speaker A (3 speakers in parallel) and the bridged connection for speaker B (3 speakers)? Thanks!
1 Answers
Hello Jean-Philippe, What most people will do is run a speaker selector off the AMP300 to convert it to a multi-zone system. Alone, the AMP300 can run up to 3 pairs of speakers off each of its 2 zones (A & B), but you will be limited to controlling all of them together rather than separately. By adding a speaker selector, such as the ISS4, you now have an individual zone for up to 4 pairs of speakers, with on/off capability on each zone. We also have speaker selectors that have built in volume controls on each zone, such as the SSVC4.

from Lubbock, Texas asked:
June 24, 2015
I want to connect 5 AP670 speakers and 2 AP650 (7 total) to this Amplifier. How should I connect them? I was thinking in connecting 2 series & 2 parallel into one channel (giving 8 ohms to that channel) and 2 series and 1 parallel into the other channel (giving 5.3 ohms to that channel). I was considering using the Bridged Mono function in this setup. Do you think this will work? Any suggestions?
1 Answers
Hi Ricardo, The ideal setup would be to run the AMP300 to a multi-zone speaker selector and then to each speaker. A speaker selector takes a 2-channel input and divides it up into individual zones. Take a look at the ISS8 for example. Or, since the AMP300 has 2 zones, you could run a 4-zone speaker selector off each zone on the amp. So Zone A on the amp goes to an ISS4 and Zone B on the amp also goes to an ISS4. This would utilize the full power potential of the AMP300, while giving you individual zones with on/off control for each pair of speakers.

I have a 16-2 wire going from each control to a distribution panel and then another wire going to where I will put my amplifier. I have a total of 13 speakers in this system. Will this Amp handle that? I have 2 more ceiling speakers for my surround sound for movies/TV. How do I hook it up to I can listen to music upstairs and someone can watch a movie downstairs with the surround sound or listen to music through the surround sound speakers?
1 Answers
Hi John, That definitely will work with the AMP300. You'll connect your speaker selector or speaker distribution panel to the AMP300 Zone 1 and then run a volume control off each zone of your speaker selector. For the surround sound, you'll want a home theater receiver that does 5.1 or 7.1 surround sound. You can run an RCA cable from most home theater receivers to an external amp, in this case being the AMP300. Thus you will run your home theater speakers off the surround sound receiver and your stereo speaker around the house off the AMP300.

Hi, I have a Yamaha RX-V673 with 2 zones. I'm currently running 5 ceiling speakers in zone 1 and have zone 2 hooked up to your ISS4 speaker switch with a set of rock speakers on one button to our courtyard and a set of rock speakers on another button to our back yard. It works great, but now we'd like to add a pair of ceiling speakers to 2 other rooms (adding 4 more speakers). I was thinking of running my zone 2 to this AMP300, then outputting the ISS4, Thus powering my 4 rock speakers and my 4 ceiling speakers, but I read in these comments if you use 2 different sets of speaker selectors you get more power? What would be a good configuration for what I'm trying to do? Thanks!
1 Answers
Hi Michael: Are you using Volume Controls for your two outdoor speakers? It is wise to add an independent amp from the zone 2 output when using a speaker selector. Especially if you go to more than two pair of speakers which you are planning to do. The ISS4 speaker selector features a protection switch that will need to be enabled if you are not using Impedance matching Volume Controls and listening to more than two pair of speakers at a time. When you use the protection switch the signal is routed through the internal resistors and making sure that your amplifier sees a proper impedance load. The trade off is your power is cut in half. That is why we recommend using impedance matching volume controls like our OVC100 for outdoors and SVC300 indoor for your two in-ceiling speakers and disabling the protection switch on the ISS4. Adding the volume controls also gives you additional control at the zone where the speakers are located. Another path you can go is to purchase the AMP200 and the SVC4 Speaker selector featuring internal impedance matching volume controls. You do have options TL/3121

1 Answers
Hi Bob, If the volume controls are impedance matching then you can use the ATM-7, if not, use the DSM8 because it has built in impedance protection. Personally I would recommend running two smaller speaker selectors, 1 off Zone A and 1 off zone B of the AMP300. This way you get twice as much power.

I have your 12 pair speaker selector and I am running 8 pairs of speakers with their own volume controls throughout the house and outside on zone 2 of my receiver. On zone one I am running a 5-1 home theater in my family room. My old receiver had a powered zone 2 and I never had an issue with it shutting off. I now have a new Yamaha receiver that was supposed powered zone 2 but it obviously will not handle the load as it keeps shutting off. Will this Amp solve my problem or is there a less expensive option?
1 Answers
Hi Brian, Yeah, this amp will help as it is high-current, meaning it can handle multiple pairs of speakers with no problem. To get the most power out of the AMP300, you want to utilize both zones which give 150 watts out each. If you just run a single speaker selector on one of the zones, you're only using half the amps' power. My advice would be to run half the speakers on zone 1 and half on zone 2 by splitting them up among two speaker selectors. BM 2772

Currently, I am using a Marantz SR7008 receiver (100W/ch) to bi-amp a pair of Jamo speakers (2x100W for 2 drivers per speaker). My other option is to send the front L/R channels via the line outputs to an external amp. I am looking for an external amp that can power the pair of bi-ampable speakers (6-ohm impedance, 250W power handling) to give me better imaging and sound stage. Can I use one AMP300 (speaker A and B outputs) to bi-amp the Jamo speakers? Or should I use two AMP200 to daisy-chain the outputs to the speakers? I am not sure I have the shelf space for two AMP200, so I prefer one unit if possible. Please advise. Thank you.

Hi Howard, Thank you for contacting us. I guess before I can give you a useful answer, I would need to know a bit more about what you are wanting to accomplish here. Is your goal to have more power only or to be able to control the volume of your tweeters/woofers separately? If power is your goal, adding a single AMP300 isn't going to make much of an impact compared to your Marantz Zone 2. The AMP300 has about 25 more watts which wouldn't make a difference. You would need two AMP300s, one per speaker, to really get more power than that Marantz can give you. But then you are taking control away from the Marantz with all its features and limiting control to the AMP300. If control is your goal, whether you go with the AMP300 or the Marantz for power, you're going to need a stereo crossover box to run through in order to successfully "bi-amp" the speakers. Let me know what your goal is and we can go from there. Thanks! -Bm 2504

Hi Peter, Thanks for the question! To start, you're going to need a multi-zone speaker selector. Depending on how many rooms you have, you can go with the ISS4, ISS6, ISS8 or even the TSM12. Each pair of speakers will be run back to their individual zones on the speaker selector. The AMP300 will then be wired to the input of that selector, providing the power to each zone. As for the IR, the AMP300 is an analog amp, so it is not directly compatible with IR. How does the IR system work with these speakers? -Bm 2336

1 Answers
HI Mike: The AMP300 is a two channel stereo amplifier that features automatic priority source switching. You have a couple of choices to have multiple sources (two or more as in you example). You can go with a basic 2 channel stereo receiver and connect to the pre-amp outputs from the Receiver to the RCA inputs of the AMP300. And just in case the Receiver does not have pr- amp outputs you can connect the speaker outputs (right and left +/-) to the High level inputs of the AMP300. The Receiver has the pre-amp built in which would allow input and switching between your multiple sources. The flexibility of the AMP300 will give you multiple options for the connection. The Receiver will also control the Volume Levels more effectively. A second option is to connect to an Home Theater Amplifier that features a second zone pre-amp output that would connect to the AMP300 and the pre amp would be in the AVR. I am hoping you used four conductor (right and left +/-) to each room and then utilized Dual voice coil stereo speakers to your three separate rooms. Checkout our OSD-ICE-840TT for the single stereo speaker application. The stereo volume control like our SVC-300 works perfectly with these speakers for your application. TS-2214

1 Answers
HI Jesse: You should have no problem connecting and driving the two pair of BOSE 151 SE off of Speaker A wired together in Parallel. You have a couple of choices for the Sub woofer. You can look to connect a passive Sub woofer as long as it has a built in crossover. First I would recommend adding two OSD OM-SUB200. One for each pair of the BOSE 151 wired in line with the Sub. Then output Speaker A to one of the OM-SUB200's then connect the one pair of the BOSE 151 to the output of the first OM-SUB200. Then repeat the same to the Speaker B output to the second pair of BOSE 151 to the output of the second OM-Sub 200.The OM-SUB200 has an internal crossover that will provide the right low frequencies to the 8" passive sub woofer. You can also add our SMP-250 dedicated Sub woofer amplifier along with a passive sub that does not have or need a internal crossover since the crossover is built into the SMP-250 sub amplifier. The first option is a great value that will take advantage of the AMP300 output capability. TS-2206

My plan is to run speaker wire from Speaker A to one selector and Speaker B to the other selector. I will need to use A and B at the same time occasionally. Will this work? The manual says to use A OR B.
1 Answers
Hi Brian, There should be no problem running one selector off Speaker A and a second speaker selector off Speaker B. The SSVC4 volume control has internal settings for impedance matching. We ship the unit with the internal jumpers set to 2X. If you connect both speaker selectors and plan to play all eight pairs of speakers on a continuous basis, you may want to change the internal jumpers to 4X for both speaker selectors. You will need to remove the cover and expose the jumpers located behind each volume control. There are six pins for each. The jumper connects two pins at the same time. To set the jumper to 4X, you will need to cover pin numbers 4 and 5. That will insure both Speaker Selectors show an 8-ohm load to the amplifier. Then when you enable both the Speaker A and Speaker B at the same time, the amplifier will see a 4-ohm load well within its operating zone. The amplifier is optimized to work at 4 ohms (note it has a 2 ohm rating as well) which is why we refer to it as a high current power amplifier. When the impedance drops, the current demand increases. The amplifier also starts to generate more heat and the AMP300 has ample internal heat sink to handle the new demand. #1668 TL/MA

I purchased this ...
I purchased this amplifier to run a pair of the A830 outdoor speakers. I was leery about purchasing this amplifier because I couldn't really find a good review of it and it also has a noise rating of "less than 0.2% THD N" when I ordinarily never purchase an amplifier with a rating of anything above 0.0x% (x being a value of 1-9). One thing I did find odd about the amp was that the "Master Level"? of both channels was turned all the way down to low, or off, thus making no sound come from the speakers when I started testing the amp. Once I noticed this setting I corrected it by turning both "Master Level"? channels up to the middle. This middle setting produced enough volume to make the A830 patio speaker loud enough that the neighbors were looking out of their windows. The A830 at this volume were clean, no distortion, and I couldnäó»t be more pleased with this amplifier.

Well, what can I say... I ...
Well, what can I say... I really enjoyed my experience with OSD. Not only did I place my order 4 days before Christmas, they actually emailed me, and spoke to me on the phone, over the holidays to ensure my product would be shipped in time. I purchased a sizeable amplifier, and two nice speakers for our back deck... And the quality is simply great. The amp, is built more solid than my 1500$ Harmon Kardon receiver, with a 4mm thick aluminum front panel, and good quality caps/EMI shielding on the inside. These guys were even a pleasure to deal with, as I live outside of the US, they called me (on their bill) to discuss ways to make the ~600$ shipping, MUCH cheaper. We ended up getting shipping down to 200$, for a 97lb order. I was very pleased... and would order from them again.
