Re: Difficult to install new boat stereo?
Not hard at all but if you are cutting the hole then thats the hardest part but if you use the under dash kit its easy. find your power , ground, and then run your speaker wires to yous speakers and your all set but as for witch battery I would just look under your dash and tap into your fuse panal oor a power off your key switch that was there when the key is off so is your radio and it will be on the same battery all your acc are on.
