As far as power goes right now I have 160 alt which is getting replaced soon. Kinetik HC2000 in the trunk, Optima Yellow top running the car and a 10 farad rockford cap im getting rid. Tim from Audiotistics told me about these group 31 batteries that i can put in the trunk and replace the kinetik and i'll be good(also getting rid of the cap since the batteries will be right by the amp). So as of now before any other suggestions thats what the plan is for now.
