Amp isn't getting any power

I have a Kenwood 1000watt amp hooked up to 2 12" MTX subwoofers in my car. Just recently, the subs stopped working almost completely. Occasionally after the can has been off for a while, they'll work for a few seconds but then shut off again. I've checked the voltage on the wires with the car off, and everything is fine. But when I turn the car on, the voltage slows to a trickle. I've checked the fuses and connections, everything seems fine. What in my car could be draining all of the power when i turn it on? Everything worked fine until a little while ago. Any help is appreciated.

Re: Amp isn't getting any power

what is the impedance load on the speaker output of the amp ? How do you have the subs wired (parallel, series, .. ) ? You may have too low of an impedance and damaged the amp or the subs.

Re: Amp isn't getting any power

I'm assuming you have your power wire from the amp hooked directly to the battery, and a suitable ground ?

And by reading your post, Im gathering your voltage drops once teh car is started ? What does it read before starting, and what does it trickle down too ? Have you tried measuring the voltage AT the battery and seeing what type of behavior it exibits?
