Most of the cd/radio's i have seen have had a reset button in the front. sometimes they just don't boot up properly and they freeze.
I use a tooth pick, it is a small hole with a button inside it, some times under the detachable face.
Give it a try, at worst it resets your radio stations!!:rofl:
:agree: Go to a car stereo store to get it fixed, some work on boats as well. A good one will find the prob straight away!! :cheers:
P.S. Can you use a multimeter?
There are normally three power wires, Dont know the boats colors but this is normal 1)Permenant power(yellow 12v+)2)Accesories power(red 12v+) 3) Earth(black 12v-).
There are eight speaker wires, four pairs, white/grey/purple/green. These measure 4 ohm's. The one with the black stripe is negative.
Pull out the wiring harness from the back of the stereo and test for these measurements.
Another way to test speakers is to use a AA battery, touch the battery to the wires going to each speaker and they will make a sound so you can tell if they are working!!!
