So I keep killing amp heads. I've currently had 3 hartke lh1000's and they all just died on me one day. I never ran them above 3 on the volume and I paired them with the hartke ak410, using the locking speaker cables. I then got a LH500 that died right before my last LH1000 went up in smoke. I have no IDEA WHAT IM DOING WRONG. And the amps don't die right away. They'll be good for a few months to a year and then just die. The last one literally went up in smoke. So could it be a short in the bass cab? I just can't figure it out. I just ordered a peavey headliner 1000 and I don't want to kill it too. Any help would be greatly appreciated. And sorry if I didn't explain this the best.
