25W Outdoor Marine Amp/Receiver OSD-MA2

Hi Pat, The MA2 is an application piece for outdoor use and is not considered a workhorse. Therefore, it would have trouble with BOSE 4-ohm speakers. Sound quality would not be considered a strong suite, nor is high output and heavy bass a part of the MA2 vocabulary. When it comes to power amplifiers/receivers, you get what you pay for in power and functionality. Check out our AMP200. This is true Audiophile Sound Quality High Current Amplifier. Then we can talk about designing a system. TL/MA

The MA2 should be used with 8 ohm speakers and you have a choice of powering the unit with a 12 volt Cigarette lighter adapter plug. Hopefully you have a cigarette or 12 volt outlet on your golf cart. Our outdoor patio speakers might work the best for you application. CL

Hi Birddog I believe you can connect your Moto Phone as long as it has a headphone jack. Just connect the Mot phone with an aux cab;e (3.5mm to 3.5mm stereo - 2 stripes on the pin). Then connect the other end to the Ipod input of the MA2. TL/4493

Hi Dave: Not sure if this is enough power and it is a chip amp that does not make your speakers sound better. Better choice would be the XMP100 a true digital Amplifier. that is 93% more efficient. The MA2 is a class AB am=p meaning it is only 50% efficient. Good luck TL/4469

Hi Davis: This is a 8 ohm system only will run a single pair of 8 ohm speakers left and Right stereo. It does have a signal low level pre amp output as well. TL/4428

Hi Scott D: In audio there is a Theory of Relativity applied to matching of the components of your system. Your cost for amplification and source should be close to equal what you paid for your speakers. BOSE products are excellent but you are paying a premium. So you should be budgeting around 60% of what you spent for the Speakers. Your best buy for this would be our OSD AMP200 and add a $20.00 Bluetooth Dongle as one of your sources so you can stream your source from your Bluetooth enabled device (Smartphone , tablet or laptop). The AMP200 features automatic source switching between two sources, one could be your Bluetooth Receiver(checkout Bluetooth Receivers at AMAZON) and the other could be a hardwired option like CD/DVD Player or even your laptop that has your digital library. Checkout the Price of the AMP200, unlike the BOSE the AMP200 is way undervalued, a great Performance/Value quotient. No problem getting all the Bass and clarity you want. This is a High Current true Audiophile Amplifier. You will even be able to add a second pair Free Space 51 down the road adding the pair to Speaker B. TL/4245

Hi Rob, This is a marine rated receiver so it can be in a high-humidity area. As for the speakers, it depends on how much watts they can handle and if it's a wired speaker or not. Most computer speakers work off USB or RCA connections and aren't the type that run to an amplifier.

Hi Mike, They are speaker wire adapters that look very similar to RCA, but are not RCA. It's similar to a banana plug.

Hi David, The MA2 can power them but it only puts out 25 watts per channel, an 8" speaker like the OS790 isn't going to reach its full potential with only 25 watts.

Hi Don, Yes - this is the only outdoor, marine-rated amp/receiver that we sell.

Hello Brian, You can order it once it's back in-stock within the next few weeks at the link below: https://www.outdoorspeakerdepot.com/wireless-speaker-powersupply.html If you are in a rush, give us a call and we'll find a solution. Thank you.

Hello, The MA2 outdoor receiver is unique in that way. It includes adapters that plug into the amp and bare wire to the speaker. CL/MA 2024

Hi Walt, The MA2 is our only receiver rated for outdoor use but it will not have the power for your requirements. You might have some trouble finding an outdoor receiver that will drive four speakers. Most times customers build an enclosure or run the wires from indoors. I would recommend our AMP200 for an application like that where you can protect it. You can use our bluetooth source kit the RS-BSK1. CL/MA 1931

Hi Matt, The MA-2 outdoor receiver/amplifier is 25W per channel and designed for background music. It is not bridgeable and will slightly under power the AP490s. You can mount it in any position with no trouble. CL/MA 1867

Hi Roscoe, Our MA2 outdoor amplifier is 25 Watts per channel, so be sure that it is compatible with your current speakers. The alternative is to use an amp indoors like our AMP200 with a volume control in each of your 3 zones, like our OVC300. With an outdoor volume control in each zone, you can control the volume independently for each pair without having to go back into the house. The advantage of an indoor amp is more power for your outdoor speakers, rather than settling for a smaller amp that may under power your setup. CL/MA1809

Hello, The MA2 amplifier will technically drive the speakers for your unique application. The speakers may be slightly under powered (less volume capability), especially with a long cable run of 150 ft. You might consider using a more powerful indoor amp such as our AMP and placing it in a shed if possible. Using 14ga wire should be fine. Good luck with the critters! CL/MA 1775

Hi Casey: I would not go with less than our AMP120 to drive your 8" KLH rock speakers. Timing is good checkout the Cyber Monday special on the AMP120. TL 1414

Hi Rick, You can connect anything that accepts an RCA cable or a 3.5mm (like a headphone) to the MA2. CL/MA 1196

Hi Jerry, The MA2 puts out 25 watt per channel so our smallest patio speaker would be the way to go. Take a look at our AP425 CL

Hi Ed, This unit comes with four speaker wires, which measure about four feet long. They are terminated with RCA connectors on one end (that plugs directly into the MA2 back panel). The other end of the cable is 2-conductor: red for positive and black for negative. These are not terminated but rather bare wires. You can extend the cables (if they are not long enough) by splicing them with something like our CL3- rated 16-gauge, 2-conductor cable which is ideal for in-wall, outdoor and direct burial applications. If you need to extend the cables, I would recommend splicing into the cable as near to the input connector as possible (within a foot of the connector). I hope that answers your question. TL/MA

Hi Slash, This outdoor receiver is typically used with 4" speakers or smaller so you might find you'll need more power. We recommend using the AMP120 indoors and then running speaker cable outside to the speakers. This will give you more ideal power and maximize sound quality. CL/MA

Michael, The MA2 comes with the mini cable that would connect directly into your headphone jack of any ipod, iphone, or mp3 player. CL

It will play music, but it might not be enough power to really drive the speakers to their full potential. The Yamaha speakers are 6 ohm, not 8 ohm (which is critical for the MA2) and the sensitivity is 85 dB which means they take more power to drive. Something like our AMP120 or higher would be a much better match. TL/MA

Hi Steve, There is an antenna in the box just for FM (about three feet of 20 gauge wire with a simple loop at the end). If this is not sufficient, you can try to create your own antenna by making a longer wire with a loop at the end. Then try moving it around to different positions without you holding it (you become part of the antenna while still in your hand). There are some commercial FM antennas available as well but then you're spending more for the product. TL/MA

Jim, Those are 4ohm speakers- so this would not work with the MA2- If you are running a single pair you should hook up our AMP120 or AMP150. Although this would not work for your outdoor application because they are both indoors. You would have to build them into something totally protected from the elements. CL

Christy, You can use this with a wireless system yes. Check out the popular WR800's - Their great! CL

Gary, Yes we do, the power supply is 29.99. Your reference number is 211679 CL

Hi Marlin: The MA2 have been shipped from our Factory, they are literally on the water. We expect them to arrive the first week of May. TL

Mike. This comes with the rca cables that would go directly into the tv. CL PS: Just make sure your TV has pre amp output for the audio first before making your purchase. It has to be an analog (right and left RCA) output so you can connect to the input of the MA2.

The MA2 comes with four speaker cables featuring an RCA jack (two black and two red) at one end and two bare wires (positive and negative) at the other end. Although the unit was designed for two pairs of speakers, we typically do not recommend more than a single pair. Connecting two pairs causes an unfavorable load (four ohms or lower depending on the actual impedance of the speakers) for the internal amplifier and eventually causes it to shut down. One thing to consider would be to use the MA-2 to drive a single pair of speakers and then adding our OSD AMP60 to drive the second pair of speakers. There is a cable included to connect the two. The AMP60 also features four speaker outputs but the same rule applies as the MA-2 (recommending one pair of speakers only). In this setup, you will have no problem connecting or driving your current two pairs of outdoor speakers
