I recently purchased a used (my mistake..) Kicker zx750.1 mono amplifier to power my two Alpine 10s.. I wired everything myself and all was fine and well until about 2 weeks ago. It started slowly, but my subs started going in and out (going from full power to about 30% power.. they never really completely went out) every once in a while, so I rechecked all the wiring and tested the subs and they were fine. Sometimes it would magically start working 100% for a few days in a row, but then the other day they went out and stayed out. When I first wired my system, I set my amp at 80 hz, gain about a fourth the way up, and bass boost all the way down. I never really pushed them too hard for fear of blowing them. Now, the only way to get my subs to hit the way they used to at those settings is to turn the gain and the bass boost up.. but even when I do that, they only hit every few beats. I've checked and rechecked my remote wire, RCAs, hot and grounds, and my speaker wires. I've wired someone elses amp into my car and everything works fine. It's got to be the amp. So, I cracked open my amp today and I can't find ANYTHING wrong with it. Please help me???
