Re: Car stereo/cd versus marine stereo/cd?
I just bought/installed an auto radio, JVC, AM/FM/CD, with a detachable face, Aux input, remote at Walmart for $95....20watss RMS. (Sony and Pioneer both had 14watts and 17 watts RMS) So it's go nice power without needing another battery. I'm debating mounting new rear 8" Pyle marine speakers on the kick panel under the rear seats.
Mounted it in the glove box opposite the controls....I also took the door off for a sleaker look, and easier access to the radio, and the remote works. The detachable face goes in the house when we're not using the boat, so it's not in the elements.
