[QUOTE="keep_hope_alive, post: 6738974, member: 576029"] you have two dual 4 ohm subs, and you want to connect them to the amp. if you wire them in series as you describe, you'll have 8 ohms per sub. Then you can combine the two subs in parallel inside the box, or at the amp - resulting in 4 ohms total. there are two (+) and two (-) terminals on the amp so you can parallel speakers easier (instead of cramming two wires in one terminals). they are connected internally, so use either one or both. 1/0 would help with voltage drop, it's never a bad thing to have larger wire. if you get everything installed, and you can't maintain voltage after the big 3 and new battery, go with an alt or turn it down.
