Eclipse headunit When I am playing CD in unit the front speakers turn off and then turn back on. The front speakers are connected to jl audio amp, but rear speakers are factory and are still powered by headunit. This problem does not happen when hearing FM Radio stations, only when cd is playing.

It should be blue/white.

Good be a ground issue from the headunit. Try running the amp off another source (another deck, an ipod etc) See if it goes away then.

silly as it sounds, you may want to check your EQ settings on your headunit. Things like sub volume, SLA, loudness and balance. When they replaced your battery, those old settings were lost.

How is the sub wired?
Are the gains up?
Have you searched for subwoofer volume settings in your headunit?

did you test for power at the amp, you should have 12 volts when the deck is on at the amp on the power and pto terminals. Also check and maybe reground the amp

3 things make sure all the speakers in the car have tape to avoid grounding the speakers
next make sure all wires in back of unit are taped
if all that is taped good its the amp over loading use a larger ground wire to fix this
hope this helped

check all wires on this unit.

If this occurs with the head unit plugged directly into the amp (no signal processors inline, you probably have open shields on the head unit.

To check the shield ground, disconnect all RCA cables from the head unit and measure the resistance between the RCA shield on the head unit and the case of the head unit. It should read ~0 ohms.
