Question about MTX Thunder 8302 Car Audio Amplifier

1 Answer

Amp not workign!

So i got two JBL gt10801 subs that are 250 rms each and i think SVC 8 Ohm Impendance..I also got MTX Thunder 8302 amp along with it.. I wanted to test my subs since i did not have wiring for my car yet so my friend hooked up one of the subs to one of the channels of and it was pounding good. Then he hooked up the other sub to to the other amp and everythign was sounding pretty good for how much wattage the amp was giving out. I dont know what he was doing but i know he was playing with the buttons and stuff on it (amp over and rca over). I told him before to tighten the ground properly but he said as long as its touching then its good. So the amp was on the sub box and all of a sudden there is no more bass. My bro says shut it off becuase he smelt something liek burning rubber. We checked and it was coming from the amp, and the groudn wire wasnt in teh back of the amp. The amps red light turns on but sometimes takes forever to turn off even when the power cable is out, and there is no power at all going to the subs. Anyone have any suggestions, and if my amp is a lost cause? How much the price would be to repair? Thanks alot!

The way you were testing the amps is a common way that alot of people do and this is the main caise for the amps to blow up.. An amp should always have a BOLTED ground and B+ connection as well as good speaker connections to ensure no intermittant connections. When the intermittants do occour, these solid state amps are very unforgiving and will instantly short out one or more of the output devices or take out the switching power supply. Im afraid you cannot guess with the repair price on a unit like these, as it could have taken out one resistor or a whole line of solid state output devices. the only true way to tell would be to bench test the units with the proper equipment. I would be quessing, your repairs are going to go from 65.00 all the way up to 200.00 bucks, most likly excedding the cost of most amps.
