 Subject: Dual voice coil wiring help, please
IP: Logged
Message:
I want to know if I can wire a dual voice coil sub into a single external enclosure (box) connection, then run two sets of speaker wires from the box connection to a 2-channel amp and get more power out of my amp. I want to run both channels at 4 Ohms, since I my amp isn't stable at 2 Ohm bridged. I am looking at the Rockford Fosgate HX2 RFD2208 8" Dual 4-Ohm Voice Coil Component Sub. I am worried about the bottleneck at the external enclosure connection. the box is a Q-logic .3508 (only .35 airspace), and I don't want to cut and paste another connection to the outside of the box. If it won't work, I'll just go with the HE RFP3408. Any help would be greatly appreciated.
Thanks!

I would not recommend using one channel for each voice coil since the bass in stereo channels can be different and thus cause damage to the sub. Your first option would be to wire the sub to 8Ohms (series) and run your amp mono. Amplifiers usually put out as much power in 4 ohm stereo as they do 8 ohm mono. Last option would be get a 4 ohm sub.

Awesome! So do I simply wire one voice coil to the other (+ to +, - to -), then run the connection to the box connection; after that, run the box to the 2-channel amp bridged?
If this is correct, will that be better than running a single voice coil woofer bridged at 4 Ohms (one that isn't as good of quality anyway)?

With that sub your only choices are: 2ohm mono or 8ohm mono
So if your amp can't handle 2ohm mono, your only choice is 8ohm mono (cause you can't use a single DVC sub in stereo). So wire it up like this:
AMP + to + coil 1
AMP - to - coil 2
then hook the + to - on the remaining coils
So if you want one DVC sub make sure you get dual 8ohm coils or an amp that can handle 2ohm mono or get 2-4ohm DVC subs.

The only Dual 8-Ohm VC sub I saw was a Kicker that won't work in the small amount of airspace I have available. I don't think it will be any better to wire it as mentioned above. I think I would just be better off going for a single voice coil. After all, we are only talking about an 8" speaker.
Thanks for all the help.

Sorry for the double post. I had to clarify something.

A Kicker L5 8" would be happy - and snappy ;) - in that air space.
A dual 2 ohm speaker could be run as a single 1ohm or as a single 4ohm load. I assume your amp could handle a single 4 ohm mono load bridged, most can these days. The other choice is a single 4ohm sub to make your life even simpler. The advantage of the dual voice coil subs is the vast combinations of ohm loads that can be achived with just a couple of speakers - that's all.
As far as where the actually wiring connections go (inside or outside the box) it does not matter.

I really dont know anything about amps or subwoofers but I just bought 2 Boss R3000D
CLASS D MonoBlock Power Amplifiers (can work in 1,2,4 ohms) and 2 Audiobahn AW1006Q 10" Flame 900W RMS DVC Subs. Usually most speakers only have 1 set of audio inputs, this subwoofer has 4 on each sub. I really have no idea how to hook it up. Could someone please explain to me how to. A diagram would be really helpful (sub wiring).
Thanks,
John

check out rockford fosgates website. and go to tech info then to woofer wireing wizard. you simply input the vc specs for your subs and it gives you all the wireing options

John, sell or give me one of those amps, you don't need it, that is too much damn power.
Connect one negative and positive together on one of the subwoofers(negative on one voice coil to positive on the other) Do this on each subwoofer. No wires should be connecting one subwoofer to the other at this time. Now run one positive to the positive on the other speaker and run that to the positive on the amp. On that same speaker run it's negative back over to the other speaker's negative and then run that to the amp. This will push a 1 ohm load, which will be 3000 watts, you need to turn the gain way down to about half so that it only does about 1500 watts, otherwise you will be pushing too much power to the speakers. Buy yourself a capacitor, and wire that in too. Please give me that other amp though, lol. Any questions, email me at cloudcity2001@hotmail.com

4 SETS of inputs per sub or 4 terminals per sub? A DVC sub should have 4 terminals or 2 sets of two (a + and - is a set)
Cloud - just as an FYI... cutting the gains down to half will not reduce the amps power to half. The gains only control how much signal (from the headunit) is needed to drive the amp to full power. Depending on the amps sensitivity and the headunits pre-amp section you could be a max power even at minimum gain.
Anyway I seriously doubt a Boss amp would put out anywhere near a 1,000 watts, no way it run a 1 ohm load either... sorry to report - Boss's makes complete junk :( do not waste your money on it, get a real amp with real power.

Tony -
A 2 ohm sub can only be wired to be 1 or 4 ohms - not 2 ohms.
What does that amp put out into a single channel? and at what ohms load? I need more specs before I can tell you how to wire it up.
Something tells me it's 1000 watts mono into 4 ohms, in which case your screwed with those DVC 2 ohms subs since two of them wired up only give you a 2 or 8 ohm final load. At 8 ohms you get half the power or 500 watts which = 250 per sub or 125 watts per coil :( at 2 ohms you'll blow the amp or atleast overheat it constantly :o

There is some good info on this here:
http://paudio.tripod.com/subwooferwiring.html
This is a good page on how to charge a capacitor:
http://www.caraudiohelp.com/car_audio_capacitor_installation/car_audio_capacitor_installation.htm
For the money Legacy amps are really good and they have nearly the best warranty you can buy 3-5 years, which is great for the price. Check them out.
Good Luck!
