I wanted to see if any of u guys know wht the current draw for a Hifonics XX collosus @ 2ohms is....

Thanks alot...

doesn't list it on their site but it'll be a lot. they generally least peak current draw anyways and not continuous draw, but a 3k watt amp is gonna suck some current

I understand tht 3KW is gonna b alot thts why a 300 amp Irraggi alt will b here in the near future....but the collosus is prolli going by the wayside to make room for a T3 8.1....3KW @ 2ohms daily...5KW+ @ .5ohms

That 300amp iraggi alt will handle 3kW just fine...

I = P/E

Amps = Watts / Volts.

Amps = 3000 / 14.4 (nominally)

208 1/3 amps

And thats at a continous power; your subs will rarely see anywhere near 3kW, unless you listen to pure sine waves :-)

I know it will handle it w/ no problems jus wanted to see exactly wht the draw was...

that is considering your amp is 100% efficient and most class D amps are about 60% efficient, however you are correct as the amp will not be producing 3k watts playing music

damnn.i should be fine with a 200 amp alt?

Class D are not 60% effecient. Most are in the 70-80 range.

say you are running 10 thousand watts, would you be ok with a 300 amp alt or would you need 2 alternators?

I'll be honest here Jim, if u have to ask this question then I don't really think you should be trying to run 10k in ur car. But that is only my suggestion
