I just had a fatal accident involving my MA Audio HK-2000D. I turned a corner and i was thumpin... then a large cloud of smoke came out of the amplifier. The connections were fine the amp was supposed to have a protection feature... but now it won't even turn on at all. So I need help deciding what amplifier to get since the warranty is up on it. I am really considering a Orion HCCA d5000... but i need to know what other high powered amps are good. I have one 15' l7, but i will be building up soon to either 4 15' L7's or a couple other high poer subwoofers. So I need something very powerfull. Please give me some suggestions.
