Thinking about picking up a pair pf FI subs dont know model yet but i know they offer each sub in with either dual 2 or 1 ohm vc's so im wondering which i would benefit from more and why? Which offers more flexibility.

Also im looking for a reliability and affordable amp in the 1500-2000w rms range at any ohm load 1,2,4 most likely i would prefer 2 or even 4 ohm.

Thanks

A 1 ohm svc is what you have, a 1 ohm driver. A 2 ohm dvc is either a 1 ohm or a 4 ohm driver.

Thanks for the info and not to come off rude by any means but that doesn't really help me as far as my original question goes...

Thanks

Dual 2 ohm coils your choices are 2 ohm or 8 ohm. Dual 1 ohm coils, your choices are 1 ohm or 4 ohms.

I misread your original post. I thought your choices were DVC 2 ohm, or 1 Ohm SVC.

You should buy the voice coil configuration that will work best with your amplifier.

Well, you can't get a 4ohm load out of those subs. Whichever set-up you go with you'd be looking at a 2ohm load or a .5ohm load (I don't know of any .5ohm stable amps). So from a flexibility standpoint there is no difference; either a 2ohm load or a .5ohm load regardless of 2ohm DVC or 1ohmSVC.

Me personally, I would prefer 1ohm SVC...I think DVC's are probably one the stupidest things to have become popular in the car audio realm. With DVC you have to wire up multiple coils which increases the likelihood you'll do something wrong, there are more connections involved which slightly increases resitance and there's a higher likelihood that at some point a connection could come loose inside the enclosure (since there's more failure points). So again, no flexibility differences thus I would choose the SVC.

This amp would be a good choice:

He was asking if he should purchase 2Ohm DVC or 1Ohm DVC drivers.

Crap...ignore my previous post...I made the same mistake "I am an idiot" made (I guess I am an idiot too ;-))

So...you get a 2ohm load with the 2ohm DVC's or a 1ohm/4ohm load with the 1ohm DVC's. I would rule out a 4ohm load; that would be highly impractical since you'd be looking at a HUGE pricetag for an amp that is around 2000x1RMS@4ohms (if you could even find one). That leaves you with the option of a 2ohm or 1ohm load

There's not much SQ difference between an amp running at 2ohms vs 1ohm (assuming the amp is 1ohm stable). So I would say your best bet would be the 1ohmDVC's since a 1ohm stable amp that would output 1500W-2000WRMS would be much cheaper than a 2ohm amp with the same specs.
