    after doing some tests I found that I had two blown speakers on the same side.
    To veriry I took one speaker frome the goo side and hooked it up
    and it worked at both locations (floor and door) tweeters seem to be ok
    I hope it didn't hurt the amp on that side but it ran a lot cooler
    than before

    Thanks for the help

    After doing some checking I got a burn smell from the right side and it apears that I have two blown speakers.
    the tweeters seem to be ok
    I tested by taking a speaker from the floor on the other side and hooked it to both locations and it worked
    The amp also ran a lot cooler
    I hope it didn't harm that side of the amp I will find out when i get new speakers

    Thanks for all the help

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

MTX 8302 sound just quit on front speakers

hi Dan....Have you had any other service or installs shortly prior to the onset of clipping? In any case, the 8302 has Onboard Thermal Protection which is kicking in due to excessive heat. If you've had this running fine for a period of time, by that I mean at least a month, then we need to focus on why you're suddenly overheating......please update your post with any further information and progress.....good luck my friend

I have a mtx thunder 7801 and a sledge hammer box

Sounds like the subs are blown with the voicecoils fused together which means the amp is/was seeing a dead short ( zero Ohms reisitence) not good for any amp. Disconnect the speaker terminals from the amp and see if it turns on. The funny smell might have been the subs blowing up, i'll keep my fingers crossed for you.

Blown fuse??

there is an underlying cause for the fuse to blow. if something shorts out you would rather a 40 cent peice goes then the unit causing a fire. disassembly is require... look for obvious burnt parts first.

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.

Amp not working need repair

You should open the amp and check if you've popped a transistor. It could also be that you've blown a relay... which really sucks lol

Rt 202 led light red and no sound

With the system turned off, disconnect the speaker wires from the amplifier. Turn on the system. If the light stays red, then the amplifier has an internal problem. If the light turns green, then your problem is a blown speaker, or a speaker wiring issue.
