Posted August 4, 200916 yr we just got the 20.1 install in a 08 tahoe sunday with stock alt and a second batt. today the ia shut off with just 30min of playing mediocre loud. the arc ks is still playing but no bass. the volt meter show around 14v +/- 2v.

August 4, 200916 yr did you verify with a multimeter? i would say you have nasty voltage drop, wired wrong, or the gain cranked up. did you do the big 3?
August 4, 200916 yr the big 3 isnt always the answer as i havent even done it in my car.what does your electrical system consist of....does the protect light come on and stay on, or does the blue power indicator light come on, or no lights as all.try putting a jumper form the REM to the Power terminal to make sure the remote on your HU isnt burned outETC
August 12, 200916 yr Is it 14 volts when its playing?These things can draw upwards of 400 amps I'd bet its cutting off from low voltage.I'd also check the sub since 30 minutes of playing with 3k or so on a sub is pretty rough on it

How big is the factory alternator .

How big is the factory alternator .i'M RUNNING AT 1OHM SO THE IA IS PUTTING OUT ONLY 1800WATTS NOT 3000. THE FACTORY ALT IS 160.
