There's an overload caused by a semi-conductor that is acting as if was a piece of wire. If you have an Ohm Meter and there are transistors or diodes present you can check them. They will show up on the meter as if you had touched the test probes together. If it's an IC that's gone they often have cracks or damage or even have burnt. It's harder to test IC's, but the bigger the device and any on heatsinks should be top of your suspect list. If in doubt replace it!

My powered sub keeps blowing fuses every time i plug it in..Ive looked it over and nothing seems burnt or broken...It is a MTX sw1212 the sub is fine it's just the amp


check out that the output is not shorted on the terminal strip or near the connectioon to the sub woofer speaker driver.......if not then there is some other problem and you need to take it to a trained technician .......as you yourself can't rectify the problem.....

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.

Try the fuse first then if no problems alls good , but if it still hums it could be the crossover board inside , if you love your sub like i love mine you will just replace the crossover if need be . Smirf 617

Not working


disconnect the subs from the amp and check to see if the amp will turn on and stay on-check the subs to see if they are blown with a different source try a pair or a single sub that you know works fine on the amp and see if it plays-this should tell you whether your amp is fried or your subs are roasted

I need help tring to put 4 mtx subs in my car


depends on the car.

suvs;
get a box made for 4, the fire towars the headliner or the floor but work. or you can make a U box and fit 4.

to fit 6,
4 in the trunk and if ur back seats sit high enough 1 under each seat.

of a custom box to hold 2 in the front, 2 on top and 1 on each end. = 6... all in one box. loose sound quality but would work.

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.

Help! Amp not turning on


Im sorry to have to inform you my friend, if you saw smoke, you burned one or more of the resistors or output devices inside the amp. Without a service manual, it will be a hard call on what exactly cooked. In alot of cases please forgive me for saying so, but the ampis not worth taking into a repair shop to be repaired, because of the high cost these days of labor. Its too bad there are no user replacable parts inside of these amps. Good Luck. Ps Please do not forget to rate this thread?
