Haynes has a pretty good diagram for the truck, but if you are looking for the system itself, google works awsome if you put in the make and model of the units you are using. I am in Belgium and hooked up my system and she rocks. 2 10" MTXs in a sledgehammer box and an MTX amp with a 10 farad cap. I am hitting 148 with those 2 10s, that box is frickin rediculously tuned to 45hz and is killer. The box is expensive, but well worth it!!!
