i have a 1.2farad power cap 3000w loudest monoblock amp 2 pioneer 1200w champion series subs and the 3000w loudest wiring kit i am keeping my exisitng headunit in my grande punto sporting so i brought one of those rca cables to wire in but i need a diagram is any one able to draw me a diagram how how i could wire all this up in the boot of my car as it would be a great help thanks

Right well you dont need a Diagram because unless you just want bass and no other speakers working then it wont work. By the looks of it that requires you to cut the speaker wires and attach it to them.. If this is the case i wouldnt recommend that you put a high level output on a Low level input of your amp.

Sorry just seen the other thread and the Guide on it and it is poss just follow the guide.
