new build help

[LiL PiNoY]

ok so i have 2 fully loaded bl's and i want to upgrade to the rockford fosgate tbdcp 2500 (getting 1 for each sub), also would like to get another amp for my highs probably the t600-4, was wondering what wiring i should get with this (i.e 00 gauge or 2 runs of 0 gauge) also how many batteries and which kind. currently have a 240 amp alternator will this support the amps im about to put in? With the two bl's what box should I get and to get the most out of my subs should I get slots or aero ports? also any other input would be great.

i dont think one alternater, at 240 amps can support 5000k but im no expert. i believe you take the watts and divide them by volts to get your alt amperage.

yeah but dont forget to calculate in the amperage that ur car is gonna take up. remember its not all going to ur subs..
