Audio Systems: Car amp not turning on???, car amp, solution c

Question
I recently installed a new head unit and subs in to my car and it all worked fine, for awhile. It worked for about 2 hours, then all of a sudden stopped working. The head unit turns on and all the fuses are ok, but still no power. I thought maybe somehow i blew up the amp, so I put in another amp and still no go. Then I got thinking maybe the trigger/remote on the head unit may not be working, so i put in another head unit and got the same result. Only this time I noticed that the amp is turning on for a split second then turning off again.

Does anyone know what would be the problem? I know it cant be the cable or else nothing would be happening, and all the fuses are fine and power is getting through. Can anyone help???

Answer
Well, you really need a voltmeter or vom so you can tell for sure if the amp has power getting to it.  You can buy such a good little auto vom at home depot or walmart for under $10.

And, in your case, I suspect the amp is overloading and shutting down because of protection activation inside the amp. This is caused by bad wiring or a shorted speaker voice coil.  So, check the wiring and the speakers.   A good check for this is to disconnect the speakers from the back of the amp, then connect only one at a time until it clicks off.

Hope this helps you find the solution.
