Eschewing the "marine"
stereos sold my marine retailers, we bought a nice Sony AM/FM with CD player at
the local Best Buy--a far better system for less money, and my experience has
been that the regular automotive systems hold up just fine on boats. We
also purchased two Pioneer 3-way speakers. The stereo is mounted in my systems panel;
the speakers are located in the forward bulkhead in the salon, beneath the
sidedecks. It was great fun cutting the large holes in the bulkhead to
accept the speakers!
I installed the stereo unit and speakers in the
boat, and have begun wiring. I ran the speaker wires along the main wire
chases and connected them to the speakers, and also to the stereo wiring
harness. I ran the ground wire to the negative bus block, and the positive
wire around in preparation for wiring into the panel.
