i didnt read everybody elses responses so forgive me if i repeat someones answer. get rid of the cap and get yourself a powercell. kinetic, xs power...something like that. they install just like a cap and help save your electrical system. if you really want to get maximum power, get a high power alt. again, if someone else has said this, my bad. too many responses to read and i just didnt feel like it at the time.
