Four 2-Ohm Dual Voice Coil Subs - Ohm Options?

[[email protected]]

What are my wiring options for 4 MB Quart DVC 10's. I haven't bought
an amp yet and need to decide how to go. Thanks for any advice in
advance, Got allot of good info to help me build my system here. I
hadn't used newsgroups in awhile, glad to see there still thriving.

At JBL.com they have a tool for that... Here's the link to that
tool...

It looks like your options are .5, 1, 2, and 4 ohms...

If you want to wire up all four of the subs together, I would go with wiring
the two voice coils of each individual sub in parallel, this will give you 1
ohm apiece. Then wire all four of those in series for a four ohm load. The
other option is to wire the two voice coils of each sub in series giving you
four ohms per sub, and then wiring all four subs in parallel giving you a
total load of 1 ohm. How you wire these subs will depend GREATLY on the amp
you buy. A bridged two channel amp most likely will require the four ohm
option. A powerful Class D amp may be able to handle a one ohm load. I'm
not exactly sure how Sponge thinks you can wire all four and get a two ohm
load.

I'm sorry, I meant I wasn't sure how Mr.Lull thinks you can get a 2 ohm
load.

So a 1 Ohm Stable Mono Amp, something like a Hifonics BRUTUS would be
cool? Hifonics BRUTUS 1 x 600 Watts RMS @ 1 Ohms Thanks for all the
help fellas:)

Chances are 600W is not enough to power 4 subs efficiently. Now I don't
know a ton about the subs you have, but I would look in the 1000W rms @ 1ohm
range. That is still only 250 per sub, which would be better than 150. My
$.02

Mosfet, I didn't think that would be do-able either, but check out that
link I put down... If you click on the one labeled (4) 2 ohm woofers
(2 ohm load) it shows a way to do it. The page does give a warning at
the bottom (as a footnote) that it's not a desireable connection...
But evidently it can be done...

According to that page, a 1/2-ohm load would be preferred to a 2-ohm
load? Interesting. However, the OP stated 4 2-Ohm DVC subs. So are you
saying to just not use one of the voice coils in those subs?

that would be bad! don't just leave a voice coil out.

Are you sure those are dual 2-ohm coils per sub? or dual 4-ohm
paralleled to get a 2-ohm final load per sub? According to MB Quart's
site, they only have dual 4-ohm at the moment. I realize you may have
older subs that were, so what is the model number of those subs so we
can verify VCs, get approximate parameters, etc?

Are you planning on 1, 2, of 4 amplifiers?

Assuming dual 2-ohm like you stated, if using 1 amp for the 4 subs, and
specs are similar to the Discus DWG 254 10" sub that they have on their
site (250W RMS), a 1000-1500 watt Class D amp would be ideal, and
provide a bit of overhead. Wiring would be a final 1-ohm load doing a
series-parallel wiring scheme.

I usually like this link for checking on wiring schemes:

http://colomar.com/Shavano/impedance_proc.php

It allows you to try out all kinds of wacky wiring schemes also.

See? I MUST be retarded... I could've sworn (when I was looking up
that site) that he was looking for single voice coil at two ohms... Oh
well, the tool still has wiring options for 1 or 4 ohms for four dual
two ohm voice coil subs. Why so much sub-age, dude? Why not get two
(or even one) nice high quality subs?
