amp problem

[reaperpr]

hello i just installed a new amp sounds fine but when car is running every time a/c compressor kicks is the amp shuts off for half a second the second amp for base stays on with no problem iam thinking ground but not sure

[pedro quiroga]

hmmm. whats the voltage at that amp when it shuts off?

[reaperpr]

good question all i know is that it didnt do it with old amp and it only does it when the a/c is on at low volume

sounds like a voltage problem to me. what size wires are you using, what kind of car do you have and what amps are you using?

[pedro quiroga]

cut the power to the bass amp and see if it still does the same thing. if not then it may be a voltage issue.

[reaperpr]

they are power acustic 2 ch 400 watt and i one 600 watt for bass oh i forgot to say it also does when i turn on the lights the problem is only with the 400 watt amp does not do it with other amp

beef up your wiring to the amps.

what size are you running and have you done the big 3.

OK i just check out the battery with a/c and lights on it goes down to 10 volts more or less could that be it?

only 10 volts??? that's definitely it.
