Run 4 12' dual 4 ohm coil subwoofers back to a 4 ohm load for bridging an amp or what about 2 woofers for 2ohm and the other 2 woofers for 2ohm as well? Post here and let me know! Thanks in advance!

can you please rephrase the question...?

so you have four dual 4ohm 12" subs... and wat amp or amp config do u want to run?

pls jsut tell me this:
how many subs, sub impedance, single or dual voicecoil?

how many ch amp? how much rms per channel at what impedance?

I am pretty sure with four Dual 4 Ohm voice coils u cant wire a 4 ohm load.. Well i wouldnt be able to do it anyhow.
Someone correct me if i'm wonrg here.

LOUD88Z

I thought this too but I figured i'd ask to make sure correct us if were wrong?

4 subs, dual 4ohm coils, 2 channel amp stable to 2ohms, hope this helps LOL!

you can wire two 4ohm DVC subs to 4 or 8 ohm. Four 4ohm DVC subs would have to be wired to 2 ohms or 16 ohm.

does that answer your question?

You could also get two 4ohm dvc subs down to 1 ohm and 4 down to .5ohm if you wired everything in parallel.

I'll add to the confusion.. [img]smile.gif[/img]

Wire each sub to give you a 8 ohm load (Series the coil connections..
2 12" Subs in Parallel will give you a 4ohm load
Run a mono signal to the amp and run 2 speakers per channel. (Being a 2 channel amp as you mention bridgine the amp)
Therefor you have 2 4ohm loads on one amplifier, therefor it will run nice and cool.
