Out of the blue yesterday my stereo started cutting out. It does it at any volume. At first it would cut out for a few seconds and come back. Then it sometimes cut out for 2 mins and come back. Went over a speed bump today and it hasn't come on since.

Deck works. Doesn't matter if its CD or Tuner. No sound but deck equalizer display shows music flowing. Its a Kenwood deck.

I have 2 Alpine V12 amps. The subwoofer amp usually shows 14.3 volts on the display but the display is dead and shows nothing at all.

I see 12 volts on the stereo side of the main inline fuse under the hood.

At the amps I only see about 4 volts going into each of them. The remote wire shows about 3 volts.

When I turn the deck off I see 7 volts at the amps and 5 volts at the remote wire.

 

Check all your connections, at the speakers aswell, the deck may be going into protection. I had a customer yesterday who wanted a new deck installed no problem, then once the new one was in and didnt work he said oh yeah thats why i wanted a new one. Turns out one of the clips on his 6X9 was broken causing the deck to go into protection.

 

First thing i would try to fix in this problem is to get 12v to the amps with the deck off, assuming the speakers run off the amps only.
unhook rca,s and
I would check fuses and ground to amp.

 

are both of your amps grounded into the same spot? if they are then that's probably where the problem is. if your deck always works but your amps go on and off go check your amplifier grounds.

 

sound like a loose ground wre connection at the deck. since the problem was aggravted by vibration
