to tell you the truth i was gonna falme the hell out of you for being on the wrong forum entirely, but just check out crutchfield.com they have videos and diagrams and everything else. if not, try the 12volt.com forums.
Battery + goes to amp +, amp - goes to chassis, head unit remote goes to amp remote, head unit RCA output goes to amp RCA input. Amp output goes to subwoofer. Then you just have to decide how you are going to wire your sub.
