Amp shutting off

I am able to hear sound for 5-10 seconds and then nothing. The amp led is on. After leaving it along for a while I can hook it up but the same thing happens. Help. Thanks, Bruce

Check your speaker load and/or bridging impedence. You didn't say anything about what kind of speaker load you were applying. Also make sure you have a large enough wire for both your battery input and ground connection. If you can pull all your speakers off this unit (after turning it off, of course)and it then will stay on, then either one of the previous suggestions may be the problem. If it still shuts off, then you have a blown amp probably. Good luck.

I have a 1999 VSta XVS 1100L. It was running great

the first thing I would be doing would be to disconect the leds & return the system to standard if your power returns the problem is with the leds did your well meaning son install a relay when he fitted the leds if not they are probably robbing power thereby causeing slow opperation of the fuel pump or weakened spark

turn on the amp and you know that the amp is good and you hear nothing
1. paralell wiring on speakers that are the wrong impedance very often will silence speakers to a eternal sleep along with that amp.
2. 4 ohm speakers mistaken for 2 ohm and are 8 ohm speakers mistaken for 4 ohm, the amp sees this load and it causes a overload on either side of the amp internal filter
( that's what makes the "pop sound") amp pops inside, literally makes a "pop" sound
you get a no sound

Amp light on but no sound

either something in your amp burned up, or the audio wires going from your cd player to your amp are bad

Amp wont turn on

New amp sounds messed up... grounds are bad and sometimes the amp tries to draw power but cant... So it immediately goes to protect... All jacked up... Audio specialist could help... Repair shop if local ..

your amp may be overheating, or you have it up too loud and the surge protector is shutting it of in fear of damage to your amp.

No power output from the amplifier...

The EEE and protect leds being on is a clear indication this AMP is toast.

Power Problem, LED Lights up and then shuts off

Do you have the switch or activate wire on the new amp. to the right hookup? If you do, then theres a problem with the amp and if your not a tech these can be a difficult thing to trouble shoot. Take back the amp or seek out a pro to test it on a bench. Good Luck
