fried amp.....HELP!

[BLD 25 10+ year member]

Hey, i need some help. A few weeks ago, i hooked up my amp, and it sparked and a little smoke came out. That worried me, but it still seemed to work. Today, i got a new amp(new to me), an mtx 500d, and hooked it up with no issues. I went back into the car, put the test tone cd in, turned the volume up to 35, and by the time i got back to the trunk the amp was smoking and then it died. I have set up dozens of systems, and never had that happen. Then i put the multimeter on the connections and it started smoking. The thing that ticks me off big is that the fuses on the amp didn't blow, and neither did the inline fuse in the wire.

What happened!!!!!!!!

could something like a bad ground do this? I just can't understand why the fuses didn't blow.

Possibly a short in your power lead? How big a fuse do you have in it? Just to see, try hooking the multimeter up and seeing if there is any current in the ground lead?

i have an 80 amp fuse inline, and when i hooked the multimeter to the power and ground at the same time, it started smoking!

it sounds like a short. Take out all your wiring and run it ALL again, something is WRONG.

are your fuses too big for the wire you are using?

check your wires and connections to the amp, then make sure your subs aren't wired to an ohm rating the amp can't handle.

i checked my wiring, and then ran two different smaller amps with no problems whatsoever. Could it be the larger current draw of the 1000w amps caused problems with the not so great ground?

doubt it, you said your DMM smoked too.
