  • Overheated Amp

    I have a MTX 704x which I think overheated. Iím a complete newbie when it comes to car audio and donít know how to troubleshoot. I was driving along listening to the radio when it cut out.

    Can this be solved with some new fuses, or do I need to take it back to Circuit City? Iím on the road now, so hopefully I can get it fixed easily.

    thanks,

    I checked the fuses on the amp and they are fine. I let it cool off for three hours. The head unit powers up fine.

    There is a flashing red light on top of the amp, not the normal blue glow.

    I looked for a reset button but could not find one.

    thanks,

    Bryon

      you need to give us more information.

      first i'd try to unhook the speaker wires and hook them up one at a time, you may have a short somewhere

          If you had it done by Circuit, then you could take it back there for warrenty work.

            Were you driving for a long time before it went out? Did you hit a pothole? Give me some more info and I'll try to help you out.

            The first thing I would do is disconnect the speakers from the amp. If it turns on and doesn't go into protect mode then, it's one of your speakers that is giving you a problem. Connect them one by one to see which one it is.

            If the amp still doesn't come on with the speakers disconnected, check your ground. If it is good make sure that you getting 12volts at the battery and remote terminal when the radio is on.

            If you are getting 12v at the battery and remote, then your amp is bad.

            Good luck!
