i am about to get either a 95 toyota land cruiser or a 95 ford f150 4door and i want a good sub woofer setup. i have been looking into running a system with 2 12's, either FI's, JL's, Sundowns, or ICON's. i also intended on getting alpine Alpine SPR-69C's, either 1 or 2 sets. what i want to know is what i need to make this setup worth while. i want to know what the small things i need are, like what kind of wiring, the best way to set up extra battery's, ETC. thanks for your help.
