[QUOTE="BassAddictJ, post: 2573947, member: 560415"] new battery, yes new alternator, highly highly recommended. some new wire, yes big 3, yes best thing for you is to do is to have 2 positive runs coming from your front battery to ur back battery. then 2 positive runs from that back battery to the input of that amp.2 negative runs from the amp back to the negative on that back battery. then 2 short runs of negative going to a very good ground spot somewhere back there. look up big 3, and the 3 main spots to upgrade, do those with dual runs. trust us the big 3 is vital, and if ur doing dual runs to the back, you need to do dual runs all over. with that much power, you can probly survive with a decent battery up front and a good abttery in the back. a decent starting battery is an optima red top. thats a "starter" battery, if you get a deep cycle battery for the trunk you;; need a selinoid to seperate the batteries if they're wired together. or a battery isolator and run just the back battery to the amp. id recommend a selinoid (i think thats how its spelled iirc). depending on ur budget, if u can afford it. get a kenetik 2400 for the back, and some kind of small deep cycle battery for the front. if both batteries are the same kind (deep cycle, lead/acid (starter)) then you dont need a celinoid or a bettery isloator. get some nice batteries and save up for a nice high output alternator. time to do some research my man....but trust me. a HO alty is worth it.
