Question about MTX THUNDER7801 SUPER AMPLIFIER CLASS D MONOBLOCK Car Audio Amplifier
Ok i had a mtx 7801 running two mtx t8512-04 subs. about two weeks ago i fried the subs. got new ones through mtx warranty. plugged everything back in.( i used to install professionally so dont tell me to check my remote wire...) turned the car on and the amp didnt kick on not even the prizm efx. neither the short or the thermal leds came on on the out side of the amp. so i took the top outer casing off of the amp and re applied power. mtx set these amps up to tell you whats wrong because there are smaller leds on the actual board in main places (i.e. line in, power transformer, output side) and the led on the board nearest the line in ( rca in ) is lit. is this like a circuit that got tripped when the subs blew or what should i test for on the board itself? any help is much appriciated.
Check pwm circuit amps turn on with 3-4 volts on mosfet gates ic 494, 5252or 555 controll these.hit me up for more

You need to contact MTX tech support before the warranty runs out. You'll probably have to get an RA number to send it back.
