When i move the ground to a new spot i get lights that come on for just a second. I have a Pyle PLA2680 Red Elite amp. The amp is hooked up to 2 12" Kicker KCVR Bridged.

After 7 yrs of use, it just stopped working


I agree that It could be one of the other reasons listed here.....

But, I had the same problem with a 1,000 watt Kenwood amplifier and it worked like a boss for the whole two years that I had it and then one day the box that I had my subs in somehow came apart and after I changed out boxes the amp quit working. It came on but it wouldn't work anymore except for when I turned it a certain way or sat it against something.. Anyway it ended up being a loose female port plug on the inside where the auxilary cables plug up.

Hope it helps.

I was driving down the road and the adio just shut off on my kvt911dvd. no noises or electrical smells, it just quitely shut off. it still works fine and the video will still play just no sound. any...


it could be a couple of things. a speaker could be bad causing the internal amp to shut off. or, the internal amp itself may be bad. i know the new kenwood recievers will say "protect" when something like that happens. then again if youre vehicle has a amp from the factory, the fuse could have blown or the amp could be bad. check all the fuses in you vehicle and see. you may get lucky.

I recently had my car broken into and someone tried to steal my system. Thankfully my fiance heard and went out in time and they drove away. They had disconnected some of my wires and we tried to put them...


wire from battery(normally red) to 12v+, really skinny wire(normally blue) to remote, black or silver wire from ground to grnd. No you dont need the converter as long as you have your rca from asftermarket cd player to your amp(preferred way). You might have also bridged your amp with your speaker wires which would cause your system to run on a different ohm which would cause the bass to get louder then overheat you amp which would turn it off.

My amp only powers the subwoofer when the radio is on but wont when the cd player is on


The person(s) who hooked up your system made a boo boo. They wired your remote turn on lead to the power antenna lead instead of the amp turn on line (both are blue and easy to mix up). Thus when your radio is on it sends a signal to the amp and the amp turns on, but when you set to CD the signal goes away and your amp shuts down. Easy fix, just re-wire the amp turn on lead and the problem will be fixed.

Visonik amps turn on into protection mode(where green not red for three days)...switched over the wires to some sony amps and they dont even turn the hell on


the fuze could be blown on the amp or the speakers are to much power for the amp at full power so try to turn the amp to half and not to turn the speakers all the way up,.
