He knows what he's doing and he's kind of a stuck up prick so he wouldn't dare to clip his stuff...

Stuck up pricks are usually the ones who won't admit they have no idea what they're doing.

i shook this one kids hand and it just folded in mine. long story short i fucked his girlfriendso.. yeah..

You want this to happen to you? Give decent handshakes people.

So if I got a Mechman that's 270A and run however many inputs on the amp I need, like if it has two sets of power inputs I'll run both sets of runs, and a new hood battery, and possibly a second battery in the trunk, would that be a good set up? Big 3 of course too. All in sky high 1/0 gauge.

If you go with their ofc I'd say yes you'll be fine. IMO if using cca I'd use dual inputs. Not saying you need them just will help your amp allot if you do.

I only plugged in the numbers from the site, i wasnt saying that's exactly what he'd be getting.. it never hurts to have an alt bigger than what you need

So would a 270A Mechman be the right choice then?

P(W) = V(V) × I(A)

power in watts is = to volts times amps

so re-arrange it to power/volts=amps

3500(watts)/(14.6Volts)= 239.73 AMP

so to answer your question, a 250 amp alternator will be sufficient, yessir

EDIT: unless you're running at 16V, which would be crazy. but if you were, just plug it into that equation, which would be : (since the site says it does 5300 @ 1 ohm on 16V) you would do: 5300/16 = 331.25amps.

long story short since my last post shit itself.

A great % for amp efficieny is 80%. So if you want 3500 watts... then you supply a system that capable of giving 4375 watts. Divide taht by the voltage you sit at WHILE playing your music at your normal listening level. I say use 13.XX volts to give yourself playing room to add amps in the future. 4375/13=336A. This is your target amperage bank.. whether you use alts or batteries to get there, is all your choice.
