I can tell you right now, you arent getting much for only 2500. I believe the 9515's are around 600-700 each retail. Amps to push them are going to be around the same price for anything decent. Caps are pointless, dont waste your money. Add in at least 1 HO alt, at least 3 batterys, and alot of 1/0 awg wire. You will easily hit 4-5k.
