Installing Rock Speakers
Installing these speakers can be very simple; just decide where you want them to go and run the speaker wire from the desired sound source. Most outdoor speakers are passive devices, which means they do not have built-in amplification and will need a source of power. Most customers connect their outdoor speakers directly to household amplification, that is directly to a home receiver or outboard receiver stored safely in a tool shed or other covered space where it is protected from the elements. The OSD team recommends you bury it 4-6” underground so that it's not visible nor pose a danger of somebody tripping over it. We also recommend using CL3 rated outdoor speaker wire specifically designed for the outdoors.

Extremely Durable
Many OSD Audio customers ask if our rock speakers can take a "Chicago winter" or an "Arizona summer," and we tell them yes. The enclosure and internal components are specially designed and sealed against all kinds of weather. We also remind folks, however, that it's not a bad idea to store the speakers during months when no one would dare to be outside. Doing this will only add to the longevity of your new outdoor speakers.

July 25, 2017
I received these speakers as a gift. What is the best receiver-amplifier to use with them? I would like them to be loud because we have outdoor parties, but I don't need any fancy features like USB, Bluetooth, AM/FM, etc. I am hoping to find something in the $50-$100 range that is small and well designed. I am absolutely baffled by the amount of information and misinformation available online. I literally have a masters degree in electrical engineering and can't seem to figure it out. Shouldn't this be easy? Thanks!

Hi Steven: The best choice for you would be the Class D XMP100 Power Amplifier. You have the ability to drive both a single or two pair of the RX550. The amp also features Automatic dual source switching so you have multiple sources you can choose from. It also features Bass an Treble controls, and front panel Volume and Balance knobs. And you even have three options to turn the unit on including Manual on/off, Auto Sensing and a hard wire connection for a 12 volt trigger. Want more sources checkout our Pre One, Pre amplifier which you can add to the XMP100. TL/4485

Hi Billy, Yes the AMP60 would be a good amp to power one pair of the RX550's. If you're looking to do more than one pair, I suggest going to the AMP120. CS 3065

Am I able to connect an ipod/ iphone up to these?
1 Answers
Thanks for the question. The RX550 need to be powered by an amplifier, thus you wouldn't be able to run a mobile device directly to the speakers, but you can run your iPhone to the amp which would then power the speakers. You may be interested in our WR-150 wireless rock speaker system, in which you would be able to run your device to the transmitter in this system. Call us at 562-697-2600 to discuss! -BM 2068

I will keep the two original speakers connected to the system in my toolshed, and split the wires to connect the rock speakers, is this the right way to do it? The spécifications on the system says that the speaker impedance is 12 ohms. Her's the link to the system: Thanks for your help.

Hi Dominic, Stereos have as many outputs as speakers they can drive. We would not recommend wiring in this manner. For two pairs of speakers, consider a receiver like the Sherwood RX4105 to drive them. CL/MA 1962

What wattage amplifier do I need to power these speakers? I see the specification is 100 Watts. Is that for both? Lets say they are 50 watts each max. Then do I need a 100 watt amplifier?
1 Answers
Joe, Most receivers are about 100watts per channel, those would work out ideal. You could get by with a smaller amp but you would not be using the speaker to their full potential CL

Can we plug into our flat screen we have on our deck? Would like to put speakers on pation below so we can hear TV a little better, during football season and bonfires :)
2 Answers
Deb, These rocks are passive so they need something like an AMP or receiver to power them. Even a stereo would power them and you can defiantly use your TV as an audio source by connecting it with an RCA (red and white) to the amp or receiver. You are unable to wire them, you might consider wireless speakers. We have the WR150 and larger WR800 that are basically just plug and play. They are self powered. CL
Customer Service - Q&A
on July 6, 2012
Hi Deb: These speakers are passive and need to have some sort of power source. Do you have a clean dry area where you can mount a small amplifier like our AMP120. It features automatic source switching. Your TV could be connected to Line 1 while connecting an iPod or iPhone to Line 2 input. While the TV is playing it would take priority over the Line 2 (iPod). Once you turn the TV off, line 2 would become active an you could play whatever you had connected. You could also select our wireless Rocks or Patio speakers which the TV would plug directly into the Wireless Transmitter. The audio signal would be sent to the main Rock or Patio speaker that has the Wireless Receiver and Power Amplifier built-in. The second speaker in both cases (rock or patio) needs to be hard wired from the main speaker with a supplied cable. In both cases you will need to be able to connect a Power Supply for the Transmitter (connected to the TV) and also big Power Supply to the Main rock as well. Checkout or WR-800 Wireless Rock Speaker or the WPA-650 Wireless Patio Speaker. Those are a couple of your choices. TL/MA

Great Sound
Ran the line over 75 feet without an amplifier just to see if they would work and they did. The sound was surprisingly good over the distance. They are very well made, look like real rocks, blend well in the garden, and have descent weight so they will not be blown by the wind or knocked around by the dogs to easy. I ordered them on a Sunday and had them by Wednesday, I was expecting over two weeks before I received them and didn't have to pay for shipping. One last thing, how can you beat the price? I have looked around and these are half the price of other options that were not of the same quality or size, and cost a lot for shipping.
