what is going on here? i had a ZX1500.1 for 5 and a half years with zero issues on stock electric between 3 different vehicles. My ZX2500.1 died earlier this year after only about 4 months of use, i sent it off to kicker for repair and got it back, not long after i lost my sub and had to buy a new one. this amp as is has been used less than a month and a half.
i was bumping at close to max volume day before yesterday, i arrive at my destination with time to spare so i sit in the truck with the engine off for about 45 min doing paper work with the stereo on at 1/4 volume. i had to run into the store so i shut off the truck accessories and go in, i come back out and turn the radio on again but no sub. i think the sub may have died or a cable came loose. so today i pull the amp and bring it in. the power light comes on, the protect light stays off. no signal output is produced what so ever. i have not opened it yet to check it out but it has got to be the amp at this point.
zero bass boost on amp, zero deck EQ, loudness, or bass boost. gains at 1/2 up on amp with remote bass volume knobb in use. the remote volume knob is used at 1/3-1/2 level.
the truck has zero gauge power/ground, a 280A mech man, and 4 group 31 batteries. 250A fuse on kicker did not blow, sub and amp were never more than warm to the touch. lowest voltage the amp ever saw was 12.2 while engine off and 13.6-14.2 while running.
-------------------------------------------------------------------------
I pulled it apart and i have one resistor and a mosfet up in smoke (from what i can tell). someone please give me data on these parts, the resistor im sure i can find but where can i buy a mosfet? i want to solder this tomorrow and fix it rather than shipping it out. so from what i can tell i have a melted 150ohm resistor and 2 burnt mosfets.
now with the mosfets do i need to match there date codes or can i just throw any of the same type in there and be done? also id like to leave the board in the amp when i work on this as the mosfets are all stuck quite firmly to the thermal tape. id like to do all the soldering from the exposed face of the PCB.
thoughts?
