It has done it plenty of times....red light comes on wait a while goes away...this time it stays permanently. I have tooken the whole car apart and put all back together, but still nothing. I think that it might just be that my amp is shot.

Sounds to me like the amp is going into protection mode. Try placing one sub on the amp with very little gain. One of the biggest reason why this happens is because the subwoofers are wired wrong. What is the brand and model number for your amp?
Is your gain all the way up? If it done this before, sounds like your over working the amp. Make sure your subs ohm load is capable with the amp load to. If they are 1 ohm and your amp is only 2 ohm stable, it would beat for a lil bit then go into protection mode to. Check your wires too.
try disconnecting one at a time each speaker till the red turns to green. One of your speakers may be bad. Amp is just telling you that its clipping and overheating due to the change in ohms of a shorted or bad speaker. Its also possible the amp is on its last leg due to heat. Heat breaks down electronics part and eventually get worse.
1st check all of your wiring, make sure the remote wire is hooked up, check to see it the RCA's are hooked up. I know this sounds stupid, but i've done it a thousand times, check to see if you hooked up the speakers. If you checked all of those and still nothing, double check your ground. Make sure where you have it grounded, you have all the paint sanded away and its a good grounding point. The red light on the top of the amp, its not a protection light is it??
that means you probably have a shorted speaker wire, a bad speaker or the amp itself is bad, try disconnecting the speakers one at a time and see if it turns on or not. if the red light stays on with no speakers hooked up it means the amp is bad
unplug the speakers and the RCA leads from the amp, if the red protection light is still lit then its 1 of your linear amps blown or mosfet depending what your amp uses..if the red light does go off with the leads all disconnected, then connect 1 lead at a time and check the light,when you connect the bad lead or speaker then the light will come on and you know that 1 needs replacing..hope this helps
First off, according to the manual, the protect light should be green. That's normal operation. If it is red, that's a problem.
If it does go red, disconnect all of the wiring to the amp except the +12V and ground. Short the remote connection to the +12V to force the amp on. If the protect light still lights red, the issue is inside the amp and will need repair. If the issue goes away, try reconnecting one wire at a time until the protect light goes red again.
