worried about voltage drop.

[Names_jeff]

Alright, I'm gonna be running 2 DC lvl 4 12's on a crescendo 2k at .5 ohm. The woofers are d2. Ill have a d3400 up front and a 240 amp singer alt. 0 awg power wire and 8 awg speaker. My question is without running a batt in the rear, as in a 3100 or somethin, would the voltage drop be too low? Let me know what you guys think! -thanks

you should be perfectly fine on that, 2k watts at 60% efficiency(running at .5 ohm) ur draw will be about 231 amps so you shouldnt have any issues

Cool man. Appriciate iit

What equation did you use to factor in draw at .5?

[jrchevy87]

i used the amps law (2000/14.4(what the amp is rated it max power at)/.60 for the efficiency(just a guess cuz of the impedience). now some ppl say divide that by half for music but i dont know, i just go by the amps law

But the current draw would be more due to the amp being at .5, would it not?

A typical class d amp runs about 70 percent efficiency so at half an ohm I figured on 60%
