My name is Craig. I have been in and out of car audio since I was 15. I finally am getting my big build going. I have 4 death penalty 12s, 2 runs of positive and negative 1/0, 4 batteries and my new alt just came, 350 amp. I need to hook it up and clamp again. I have an incriminator audio 40.1 on them right now since I blew my sd8k. I have to get it fixed but I haven't had any time to get it to my friend yet. It should end up being a good build when all is done and we test another box or two. I want one more 40.1 and another group 31, mute deadner and more wire yet. This is in a 2004 grand prix. I have components and a 4 channel waiting to go in also. Let me know if anyone has any suggestions.
