    Exclamation 2400 Digital amp constant thump at 0 Vol

    hey guys my amp i recently bought gives a constant thump when i raise up the gain on the amp to my 15" alphine speakers, when the gain is at very low level its fine but when i try to raise it up my whole car shakes because of the thumping even at 0 volume , i tried hooking up my 800watt amp and it works perfectly, maybe i ened more power for the digital 2400 or special cables? any ideas? thanks.

    A.) Sounds like you have a grounding issue.

    B.) Have you ever looked into properly setting your gains?
    Play with it, 'til it's broke.

    I had this same issue with a crossover I was using. I'd be careful 'cause it burnt out two sound cards before I figured out what was causing the problem. I don't know how to fix it though. I am sending my amp back to the manufacturer for them to look over it and make sure there are no issues. As far as the crossover, I dismantled it and put it away 'cause if it's the crossover, it's not worth dealing with the trouble... if it's the amp, then it fried the crossover. I'll be doing all the crossover duties from the computer now.

    In my case, as soon as I turned the gain on my crossover to half (gains on the amp were all the way down) I started getting this weird thump/wack noise over and over again until I pulled the audio cables off. I realized there was a serious problem when the last time I was testing, I felt the RCA cables hot to the touch. Some seriously weird internal short circuit.

    I'd advise getting it fixed/replaced.
