okay so i have a stock alternator that puts out 105 amps, two runs of 0 gauge to the back and working on the big 3 at the moment. front battery is a red top, and i also have a second red top in the trunk. . im thinking about selling the second red top and getting some diffrent batteries but not sure what to do. . i am powering three amps, a planet audio 350x4 and 2 massive p3000s. EACH massive p 3000 is capable of consuming 240amps at 14.4vdc. . opinions on alternators and batteries would be great. . thanks
