Re: upgrading truck Bose stereo in my truck, think I can reuse it in the boat?
It kind of depends on the power of the car stereo and what you are looking for in terms of sound quality for the boat.
You could certainly try it . . .
Also keep in mind that marine stereos (supposedly) have moisture protection on their circuitry, whereas the car stereo would not. So, it may not last too long.
