How many amps do i need to power

[My63bug]

I'm going to be running two Icon 12s 4.5 cubes.. i will be straping 2 zapco st1650 amps. I currently have a 95 amp alternator. I'm going to have to find a thin profile to alternator and Fab up mounting brackets of some sort to make it work. No problem.. finding the right alternator, that I can squeeze to make work for my application and clear my carburetor linkage. Any idea on what would be the minimum amperage of alternator what I need to comfortably Run about 4 k between all 3 amps. (And eventually a smaller air ride compressor)

Lol get some power supplies and bring a generator everywhere you go.

I've been pleasantly surprised the $ 135 250A Ebay alt I got seems to just about keep up with my amps. I have 2 cheap Lead acid group 75's... Yes I want a Mechman... Etc... but I am drawing A LITTLE current... and this one seems to keep up pretty well. It keeps up except when I try to bleed my ears. How much current can 2 CAB's strapped at 4 ohm be? It's basically a large case GM that claims 250A at 1200 rpm... who knows?.. but it seems to do the job. A lot of people on here hate on it... but I am drawing some amps... How much is open to conjecture but I'm probably putting 1800-2000 into my subs at max...http://i.imgur.com/eZirrn4.jpg ... http://i.imgur.com/ORgaMrJ.jpg ... heck you probably need a 300A.... 4K!
