The yellow wire should have permanent power for the memory. Check the inline fuse.

Disconnect all the speaker leads and then hook one speaker (a new, known to work speaker) up directly to the radio using a short (6"-12") piece of speaker wire. Does that speaker work then?

Red = switched power
black = ground (earth)
yellow = bat power (on)

blue white striped antenna turn on

solid blue remote turn on for amp


(speakers)
(all will have one with black/white stripe if all sets have black = ground if all sets white = hot/+

green = rear
( cant remember left/right)
purple = rear

white = left front

Red = Right front

all of this should be on the bottom of the stereo

Check your grounds, you may have a bad ground connection behind the radio in the harness or your marine battery is having a ground issue, check that out first if that checks out ok then check out your speaker connections and make sure that they are wired ok. My experience with speaker thumps and pops has to do with ground.

Good luck.

With out an input jack you cannot connect straight to your head unit. The RCA out puts only send a signal out. Your best bet is use an FM transmitter for your Ipod. The sound wont be as good but I can't think of another way with buying a new head unit.

Have you checked all of the connections on the speakers, stereo, etc. Being a marine CD player, the wires and connectors are exposed to more elements than a car CD unit. Check for corrosion and make sure that all the speakers are hooked up to the correct "+" and "-" terminals. Not sure if this will help, but thought I'd try. It does sound like a speaker connection problem.

If the button is stuck, try to use something small to clean around the button; it may have dirt built up around it causing it to be stuck. Use something small such as a paper clip or a cotton swab to clean around the button. If this does not work, you may need to disassemble the device.
