MTX Thunder 2300 Amp Service Manual

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...

SOURCE: Keep poping the 40 amp fuse on the amps itself when the volume is up at all it seems

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

SOURCE: My car AMP will play for a few minutes, then just Turn OFF

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

SOURCE: mtx 1501d no sound

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.

I have a mtx thunder 421d. I've had it about 5 years,about a week ago it started going out from time to time. I checked my hot wire and fuses,they are ok.Now the amp stop working, and dont light up. Will...

If you have proof of purchase(invoice or receipt) showing the purchase date and you are still within the warranty period then yes it would be repaired by MTX under the warranty guidlines, and by the way MTX is great at customer service and they are great to work with(very fair)!!!!
Keep in mind that the seal on the bottom of the amp cannot be broken or that will void warranty coverage.
Give them a call, you will be glad you did!

Mtx 1000xd led light is flashing and the subs will not work

The light flashing usually means there is a short somewhere. Check your wires to make sure there are no slices and are touching. Also check to make sure you have your remote wire hooked up.

MTX thunder 304 4ch red amp light comes on but no audio have triple checked all connections and they seem alright

if the lights on and there is no sound it's either a cd player issue or your rca issue or the inputs for rca's on the amp are no good. or you have your subs wired at a wrong load to your amp and it is in a constant protection to avoid burning up.

My amp doesn't turn on...

If there is a zero ohm connection across the B+ and ground terminals, it should blow the fuse as soon as you apply power.

Sond gone

sounds like an internal problem. first disconnect all spks from amp, then switch on head unit and check if amp turns on (LED ON?) then feel the heatsink, if heatsink gets terribly hot then amp has internal fault. if amp doesnt get hot then try connecting a single working speaker to each channel separately, it may occur that one channel is faulty only. amps can shut down if the speaker/s is faulty as well, check all speakers and spk wires for shorts before taking amp in for repair. cheers

Delay

10 to 20 minutes? that sounds like a internal problem in the amp. I have never heard of a amp taking that long to start up, there is definatly a problem in the pre amp stage of the amplifier.
