Anyone have any idea why an amp would work fine at low volume, but then clip on and off at high volume? The wiring is perfect, I'm sure of it (4 guage power wire into an adapter sending 8 guage to the amp, then an 8 guage ground wire; all connections are solid). The amp is a Kenwood, 2 years old, running two MTX 6000 10" woofers. I cannot for the life of me figure out what's going on.

Any feedback would be great. Thanks!

Is it under a seat or something? It may have a thermal shutoff, although it probably would not come back on right away if that's it...

Are your lights dimming or anything when it's cutting out?

The amp is in the trunk and it is not overheated. Lights don't flicker when the amp bounces on and off. When the amp worked, the lights dimmed with a hard bass hit, but that was expected because the system doesn't have a capacitor.

I had one guess for why the amp is acting the way it is. If you feed certain amps too low of an impedance (like running subwoofers at 2 ohms when the amp needs a 4 ohm load), some amps go into "safety mode" where they shut off so they won't get damaged. They might go off and on repeatedly to keep testing whether or not they're getting the right impedance. But the only way this could be the reason for my problem is if it's possible to damage a subwoofer, lowering its impedance, but not blow the woofer. Is this possible? A blown woofer just creates a break in the circuit, so it'd have to be damaged with less resistance for my scenario to work. The system used to work perfectly until a few days ago.

Thanks for the help.

My guess is that your amp is "clipping", so yes, do what the others are suggesting... Turn down your gain a bit. :)
