About three months ago i hooked up a new 600 watt car amp to my old set of sub woofers. It had been running great until about two weeks ago, when it randomly went out. I checked out all the wiring, and it appears to be fine. The weird part is that whenever i turn my stereo on, the amp powers on for about half a second and the subs give a quick low noise. After that the amp loses power, but the subs still play. They sound as if they were just hooked up to the head unit with no amp. I have reconnected every wire, tried everything, and have ran out of ideas. Does anyone know what could be making my subs do this?

Thank you for the help,
maybe the hobbit that turns the crankshaft is depressed and needs therapy?
