[QUOTE="audiolife, post: 1262458, member: 541383"] it goes alt then battery blah blah thing is unless your system is outragously powerful or you listen to rap that has ungodly amounts of long long bass notes your system will not draw "peak" current very often. i will not say a 200 amp alt isnt really ever needed but in alot of cases makes a nice saftey net. back in the day i had a large system of ppi m series amps (later even pro mos) ran it off 120 amp dual output alt. 2 batteries in back isolated i had about 200-250 max amp draw (all class ab as class d's were still ten years away lol) never had a single problem. when the lights start dimming its common sense to let the electrical recharge and it isnt bad practice to maintain charge your batteries from time to time (just dont over charge them.)
