Ok, I have a Polaris RZR, I am wanting to put some tunes in it. I know what I want just dont know what I need. I dont understand all the watts and channels thingies. I am wanting to mount two wakeboard speakers with a waterproof amp that will plug into my iphone or ipod, might possibly add sirius to it just because I have it laying around. What size amp and speakers do I need? What wiring and connections will i need for it? Can i get all of this in a kit? Thanks!
