I finally picked up my pioneer double din...375$ with install kit and wiring harness shipped!! very stoked! any ways, I can manage installing this deck with a video bypass no problem...but what my dilema is, how do I hook up my amp and sub to it? I may have missed it but I dont believe there is a subwoofer pre-out on the back...how do I tie in my amp. hookup wires to the headunit for the subwoofer? they are the typical componet wires (audio). any experiences? and if any of you have some old install pics laying around on your computer, please add em. thanks!
