i have a 96 nissan ext cab pick-up truck and will start buying everything i need shortly. just have some questions first, what would be some good amps to push these. i want about 2kw-2.5 per sub. second would i be best with a fiberglass cover or camper shell for a wall? third what kind of electrical would i need? (batteries,big three?,alternator?) or would i be just as good with the bl series? also trying to save as much as i can but need everything ne also. thanks in advance
