2 or 4 ohm VR's

[lowriderram_95 10+ year member]

I have a rockford fosgate 325.1, I'm looking to run it in 2 ohm mode. Im tryin to decide between the 2 or 4 ohm kicker comp vr's. I'm new at this stuff so I don't know which to get to get the dvc subs to work in 2 ohm mode. Any help would be appreciated. Thanks.

if you're buying a pair, get a pair of dual 2 ohm subs to end up with a 2 ohm load to the amp.

What do I do, hook up the same wire to both coils or what?

To wire a pair of DVC 2 Ohm drivers to a final nominal load of 2 Ohms wire them like so:

I don't know if your amp has enough output, however, to get satisfactory performance from a pair of CompVRs //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

Their RMS input rating is 400w or so, correct? So 800w or so for a pair of them and the RF 325.1 only outputs (rated anyway) 325w @ 2 Ohms.

After factoring in that the amp is likely underrated somewhat then we're looking at around 400w (or less) total.

You've got enough power for one CompVR but not really enough for a pair of them.

If I were you I would get a single CompVR in the DVC 4 Ohm version and run that single sub by itself @ 2 Ohms with that amp ~ like so:

Thanks Prowler. That's what I was wantin to know. your diagrams helped alot.
