Knukonceptz has pretty reasonable kits. They have a complete 0 gauge kit for $93.99. That's a very nice price for a quality kit, compared to Stinger and other such brands asking $200-250 on a kit. Also, this is a kit made by Atend. Atend is know for making pretty good quality prefabricated boxes, wire on the other hand I don't know but for 70 bucks shipped it's hard to pass up.
