Whats this problem sound like?
I power my system with and ADS 80 x4 and my sub with a 500/1. When I really crank it and the sub really starts to punch, I reach a point where the sub doesn't distort at all - it just stops. if I turn it down a notch, the sub kicks back in. Seems to me like the (stock- C5) alt isnt putting out enough power for the sub amp. Gain is set at 60%. What do you experts think?

What is the volt meter reading when the problem occurs?
Sounds like the amp is going into thermal overload/short ciruit protection. Also Jl amps don't like anything under 11.0 volts. :crazy:

I don't have a volt meter but the DIC is reading 12.2 - 13.2 fairly consistently.
If your just sitting in a parking lot or at a stop light showing off, theres really not going to be that much of a problem. But if your driving down the road at 1000 rpm's or greater and this is occuring, theres probably a problem with the regulator in your alternator. :cheers:

It sounds like heat clipping or lack of available power, requiring the amp to shut down for the caps to recharge. You may want to add a one farad cap if the heat is ok. You should be able to put you hand on it and not get burned if you know what I mean.

The DIC reads 12.5 most of the time, even with everything off and the car traveling at 50MPH. The amp stays quite cool so it doesn't seem to be overheating. I did notice the DIC dropping to as low as 12 on the stronger base hits. I thought this might be the amp "clipping" but I don't really know what that is..

It's not really the amp clipping just starving for power. Clipping is actually when a signal is produced at the maximum output level possible with lowest audible quality.
