"your easiest bet would be to wire the sub to an 8 ohm load and run the amp mono.. i think you will get the most power out of it this way.. (unless you ran it at 2 ohm, which your saying your amp cant handle)..

but it also would be ok to run 1 voicecoil per channel as long as the outputs are matched.."

If I run the amp at 8ohms it won't damage the amp, but it will be putting out less power than the rated 500 rms at 4 ohms? Also the amp is connected to the sub preout on HU and wouldn't the out put be the same on both channel on the same amp?(if i use 1ch per vc)

The amp will not put out full power unless you give it a 4 ohm mono load.. which is impossible with a dual 4 ohm sub..

you will get the same output from your amp if you run it 8 ohms mono or 4 ohm stereo..

if i read correctly somewhere thru out that, i saw that you have a pair of w3v2's both 4ohm dvc.

you were contemplating using one (not sure for what reasons) and wanting to run the amp in stereo, one vc per channel....wait ahh crap 2 channel amp, that screws up all my thoughts....i apologize. If it was a mono amp i was gonna say just wire it all in at 4ohms and give each sub 250...but the 2channel part throws me off.

i wouldn't sugest putting two different channels or even a left and right on a dvc. that seems like a bad idea to me. i would bridge the amp and wire the sub most likely in series (+,-,+,-) that should keep the amp cooler. If you wired it in paralel chances are the amp would pretty hot. Ive always found that a higher resistive load usualy means less heat, and chance of product failure.

in series its an 8 ohm load, paralell, 2ohms, but if you bridge the amp, make sure its capable first or youl have a chance to loose the magic smoke, and we all know, once the smoke leaves the amp, you can never,- ever, put it back in!

I vote 8ohm mono.

My question seems to have been a little confusing, but it has been answerd and thanx for the help. [img]smile.gif[/img]

But this is the story:
At the moment I have a 2 CV12D4's running off a USA-150x. The subs are wired to a 4ohm load and the amp puts out 500rms at 4 ohms. This works fine but, the box is huge and now I want some trunk space back. There for I am only gonna be using 1 12 in the system. Because the vegas are DVC 4ohm it creates a problem, cause the amp is not 2ohm stable.


I wanted to get a 12w3 because it needs a smaller box than a vega. However it will be over powered a lot by the amp if i run it in mono. Thats why i wanted to know if it will hurt the amp or the subs if i use 1 ch. per voice coil (150x2=300rms which is the recomended power for the W3)

OR

Use 1 Vega and do the same thing (use 1 channel per voice coil 150x2=300rms)

I did not know that the 8ohm thing was even possible, but now I do. That's what i'm gonna try.

(All these problems cus I don't wanna give up the amp........US Amps are amazing! [img]graemlins/headbang.gif[/img] )

if your really dying for a 4 ohm load, then why dont you only hook up one vc?

Get the 12w3 and run it @ 4ohms, just keep the gains down and be careful. [img]graemlins/beer.gif[/img]

the "be carefull" part is what i'm a fraid of. Don't wanna go nutz one day and blow the sub. :D cuz i'm crtain the amps underrated too. I'm probably gonna first see how one of the vegas will sound if i'm not happy i'll look in to getting a new sub. JL or save up more for something that can handel the power.
