I've done a write-up on another thread...

Google it...

You have to ground the power on wire, then use the yellow and black wires (yellow is 12v+ positive, black is negative.)

It's REALLY REALLY important you watch how many amperes the amp is pulling.

A 700watt power supply will not really supply 700 watts in the 12 volt line. My PSU has a 52ampere 12volt rail, so it can produce 624 watts in the 12volt rail, but I believe it's rated at 650, because of the 5v rail and the 3.3v rail.

They are pretty expensive, I think you would be better off finding a sub amp off parts express they are pretty cheap for home audio amps.

we use a huge ass power supply

 

[skylineTT 10+ year member]

i found a 580W 30 amp for like.. 20 bucks lol. would that suffice?

I use to run a PSU for a computer for 3 sli graphic cards it was like 1,200 watts it was 380$

Amps are key in a computer psu for a amp...the big psu i had was like 190 amps look at the cosair psu thats 72 amps for 90$ i had 2 of them powering some nice computers

 

[skylineTT 10+ year member]

so the 580W 30 amp one wouldnt do the trick for a 500 watt amp?

Don't use that shitty psu..Spend 100$ for a nice psu i had that 520 psu poped it on a amp and it blew the fuse....cheaping out on a psu is like cheaping out on a sony explod for subs
