Some crazy ish happened tonite.

Well my amp(kenwood ecxelon x811d) had been overheating lately , which i thought happened because i never redid everything from my last setup. It was hooked up to an 8g  power from a  4g distro and the ground was 8 and grounded to the a bolt. so i finally ran 4g straight to the amp, and grounded it with 4g in a new spot in the floorboard which i scraped to bare metal, and screwed it down with a copper ring terminal. and i also put in a new gm side battery terminal extender. well i cranked up my truck,(02 silverado) and i was getting more voltage to my amp, but then the voltage started to fluctuate between 14.0 to 14.6 volts in a solid rythmic pattern. The voltage change was audible in the engine. well i held the gas down @ bout 2000 rpm for about a minute and it stopped. everything has been fine sense, BUT my amp is still overheating! maybe cuz my subs are wired up for a nominal resitance of 1 ohm, but why was my truck doin that and why is my amp overheatiing?

You have an amp that is only stable to 2ohms wired up @ 1ohm. That is why it is over heating.

yes get up off the carpet, but use a fan to blow cool air on it. even with a built in fan it is still warm under the seat. better still is move the amp out in the open air.

You also more than likely have a bad ground. New GM pickup + short ground wire + amp running at 1 ohm = recipe for disaster. A high ground return resistance manifests itself in many ways, one of these ways is excessive heat builup. The lower the impedence the amp is run at, the worse the problem becomes. Read my grounding sticky, it applies to you. Failure to do so is going to lead to an amplifier failure for no apparrent reason.... unless you read the thread and apply the knowledge that you gain from it.
