My brother in law has killed two subs (L7 10" and Diamond 12") now with his new amp (Kicker 750.1 i think). Not sure if it is to much power, faulty subs, or there is something wrong with the amp. I think the VC on the L7 melted. The sub no longer moves. The Diamond put off a lot of smoke then had no sound. What do you think may be the cause for this???
