Very simple Install the CAP as close to your amp as possible.But not to close as to draw heat or short out on any thing. Do NOT put it under the hood . They arent meant to be there. Your power wire from the battery will hook up to one post and the other end should go to a fuse block / distribution block.Then to your Amp.It should,nt matter which terminal on the Cap because they usually are Bi-polar. But check just in case.Watch it those suckers can zap you if you touch a terminal and something metal at the same time.Good luck.
