Question about Car Audio & Video
I recently experienced problems with my amp. The LED no longer lights and there is no sound, although at one point it sent a "pop" through the woofers then worked until I raised the volume to a higher level (loading the amp). It then shut off and hasn't worked again since. I have checked the system for power and there is power to the amp. I was hoping that I could get my hands on the MTX service manual so that I could troubleshoot it myself. When I asked MTX, they weren't willing to share the manual, but offered to identify values of "bad components." I thought that would be difficult to determine unless there was physical damage to something. At this point, I haven't cracked the amp open yet. Any help would be great! Thanks...
Your units drawing too much current. it could be a wireing problem, a speaker problem, or the amp has a problem. the correct way to troubleshoot this would first do or have the amp bench tested. Or you can remove all the speakers and wires and turn up the amp. If the fuse still pops,have the amp serviced. Good Luck

Is your sub single voice coil or dual? If it's dual, is it wired in paralel or series? It's possible for an amp the heat up so fast, the outside is not hot to the touch. Also, the next time it happens, use a paperclip and short the 12+ to the remote wire on the amp and see if it comes on. Let me know, and be sure to leave feedback or I don't get paid

There are a number of things that can cause it to act as you described. Have you pulled the covers off of it yet to see if you can see any problems?
If you do, disconnect power from it and don't touch ANYTHING on the board when ANY of the 3 LEDs (2 are not visible from the outside) are lit.
