Re: first build 06 g6 AQ3500.1 HO alt dc 12 lvl4 xl's big 3 batts double din comp set
Box looks pretty small... a pair of 12's in 3^ft? I hope that's net space at least.
Your fuses go within 18" AFTER the battery. Not sure if that's how you have it, but they are supposed to be after the battery, before the amp. Make sure you have one up on the front battery as well.
Also, you could MAJORLY benefit from actually sealing off those doors. Get some sheet metal and deaden it, and cover up those massive holes in the doors.
