not bad... lets see are those all rms numbers? if not plz post up rms numbers bc peak doesnt mean much. ok well asllmung you were talking rms your going to need significant electricle upgrades. i recommend 1/0 wire for both power/ground and the big 3 upgrade (use seach if ur confused if nothing pops up check google if nothing there then you lied bc thats how i found out about it in the first place) then i would get a high outpult alternator. 200a minimum um in terms of batteries theres a good chance youl need some type of battery bank but depending on your price range i would get 2 to start off then upgrade as nessicary from there. also if by chance your thinking about a cap do all your elec upgrades first then see where your looking voltage wise. if your in the 13s and want to be in the 14s more often then get a good quality cap (low esr) with alot of farads. if your in the 10s and want 14s and think a cap will help (you shouldnd run that low with the upgrades stated above) then run into a wall with sissors in your hands. in terms of enclosure what are you looking at? and are you building it yourself or getting it done by a "pro" check out the builds done on the site and ask questions from there. i hope i adressed any concerns you have ect... any more id be willing to help where i can... welcome to the board :^
