View Full Version : Dual 4ohm wiring
Quick quesion, I have an 800a2 (800x1 @ 4ohm) and a Dual 4ohm woofer. Can I get away with only using one voice coil on the woofer, or should i sell it and get the proper woofer Dual 2ohm or Single 4ohm? My question is what are the con's of only using one voice coil on a dual voice coil sub?

it's a very, very bad idea to try and use only one coil.
you can wire one channel to each coil, getting 200W to each; i'm assuming that the woofer you're speaking of can handle 800 WRMS, but 400 will do until you can get something diff't, should u desire. btw, 400 is as much as u can get, no matter how u wire it.

Post some more specs, or at least make and model of the sub and amp. Links to specs help out a bunch, too. Somebody else on the forum may know a way to wire your setup so that you don't have to spend any more money, that's why I recommend posting specs.
Correct me if I'm wrong, but, assuming this is a 2 channel amp that pushes 800wx1, it should push 400wx2. So wiring each channel to its own voice coil would give each vc 400w @4ohms. Right? Depending on the sub, that amp may work...

running a DVC sub via one voice coil is subwoofer suicide -- your power handling will be cut in half and u'll fk up the driver. that's my 2 cents.

nope: this (http://www.rockfordfosgate.com/products/ez2rockford/ModelInfo/ModelInfo.asp?ItemKey=10063523&CategoryDesc=Punch%20Amplifiers) is the amp, i'm nearly positive
Those specs say:
200 W X 2 @ 4 Ohms RMS
400 W X 2 @ 2 Ohms RMS
800 W X 1 @ 4 Ohms Bridged RMS
which is completely normal; there's a slightly technical explanation if u want it
you are right about the specs for the amp.
the subwoofer is a fusion FPW1200 450 rms/900 peak. Dual 4ohm. I've just decided to run 2 of these subs on the one amp at 4ohms mono, not as much power I want to put to them, but would be a lot easier to wire, and still should pound.
Thanks for all of the help

with the sensitivity these drivers claim to have, 400 watts should be more than plenty (it's a ridiculously high number from what i've seen, but i got a much lower number from my modelling programs); have at, and have fun
