Hi, I have a crazy idea and hope for some input. First off before I ask this I am aware of 8ohm and 4 ohm application. I just built a huge deck behind my house and was given brand new yamaha outdoor speakers. I didnt want to run wiring from home stereo which is way inside the house and thought it would be a neat idea to have a marine grade car stereo flushmounted on the wall coming out of my utility room that adjoins my deck. Since alot of people have ipods and cd's it would be extremely convenient to just walk up and plug in/ pop in either one. Plus it would be weather resistent so I wouldnt have to worry about a descent stereo out in a utility room. So does anyone think it would work? I figured either a high wattage receiver or add an amp. I found a 110v to 12v inverter w/ 13.8v continous power. I'd probably need one for each receiver and amp. Just wondering how to wire each. I assume I would put the power and remote together and wire on a cigarette adapter and the ground to something metal. So any thoughts?
The question is whether the speakers would work with an automotive-based Amplifier. If they're working on the same number of Ohms, then I think you'd be fine. If nothing else, I suspect that you'd actually be underpowering the speakers, since they're made for in-home usage.
Also don't think you'd need two invertors. What's the amperage rating? It does generate 12VDC, correct? 12VAC won't work with an auto/boat stereo.
Will probably need an amp for the speakers, so splice power and ground from the amp and headunit to the inverter and voila. You shouldn't need a cigarette lighter as most inverters have post connectors. Plus, a cigarette lighter probably can't take the amperage that the amp will draw - you'll also need very low gauge wires - serious stereo installers use 0-gauge wiring.
My only question is this: for the price of the headunit with ipod inputs, an amp, the inverter, and all the wiring, why not just get a receiver/stereo made for outdoor usage? I'm sure they're not rare. I think you're looking to take on far more work and expense than you need.

Don't mind me...
Actually they are converters, not inverters ;) One adequate power supply will do the job.

the12volt • Support the12volt.comThanks for the advice. I just looked for a weatherproof outside stereo online and found something called Decktunes at Decktunes.com. Whats funny is it is exactly what I wanted to build but this uses a car stereo inside a fiberglass box with a converter,but it is pricy. I think I might be able to do it cheaper than $700.
