Dual Voice Coil Subs?

[SUP3RST4R_DJ]

hey all just wondering the pros and cons of a dual voice coil sub against a single voice coil sub?
i did a forum search and found a page but from 6 years ago which pretty much said that a dvc has more configurations and can run more power and lower ohms.
so is this info still correct?
thanks everyone

Dual voice coils are quickly becoming the standard due to their flexibility in wiring them in series or parallel. The power is dependant on the resistance, and the amp supplying the power. In general, the difference in the design and performance of the subwoofer is irrelevant to whether or not it is DVC or SVC.

If you are purchasing a subwoofer, just match the resistance to your amps requirements, don't worry about the voice coils.

^ This.
It just depends on the load you want at your amplifier, so they offer SVC / DVC subs with all different resistance in coils. Allows you to run whatever load you need at your amplifier with the amount of subs you want.

Right
Wrong

ok so the amp and sub im looking at are the ones referred by sweefu (thanks again mate) and it says the amp runs 300WRMS x2 bridged at 4ohms and the DVC sub has a nominal impedance of dual 4 ohms, so what would be the best way to wire it up? bridged in parallel to each set of terminals on the sub or what?

[StoneX]

Sub and amp model numbers? So we know exactly what products you're connecting together.

I personally wouldn't run a DVC sub on two different channels. Theoretically possible, just by running each channel out of phase with each other, but the danger of not getting the tune right could hurt the sub.

Amp: Response Precision 4 x 100WRMS Full Range Digital Amplifier - Jaycar Electronics

Sub: Polk Audio - Mobile Monitor Series - Mobile / Marine Speakers
or the SVC equivalant if everyone thinks thats better

also im using the amp to run 6.5 corel maximo speakers - 90WRMS

ohk i thought maybe wiring them up bridged at the amp and then just loop from one set of terminals to the other

Sorry can't follow that.

Anyway just spend an extra $20 and get this amp, Response Precision 1000WRMS Linkable Class D Subwoofer Amplifier - Jaycar Electronics , specifically designed to run subs.

Also have plenty of headroom for another sub down the line.

So for now get that amp, and a DVC 4-ohm sub, which means the amp will see 2-ohm with plenty of headroom so the amps not pushing itself, and then later add another one (if you feel so inclined).

Are you going to be listening to some fairly fast beat/fast bass songs? Could get the 12" sub for a more all-rounder with that amp I posted.

sorry it made sense in my head haha the reason i was looking at that amp is cos i was going to use it to run the speakers aswell, that way id only need to squeeze in a single amp in my ute cab

i listen to all sorts of different music from hard rock to bass heavy hip hop and dubstep, i looked into going with the 12" sub instead if it fits but then i end up with the same problem of trying to find space for another amp, the main reason for going with a 10" is just so i dont have as much clutter in my cabin, but im open on to opinions if a 12" sub would be better for me, i cant decide haha

Heavy rolling bass, especially dubstep, would much better suit a 12 or 15" sub. 10" are for more punchy bass.

For the amp, get this OAH500 - Amplifiers - Option Audio , thats a 5-channel amp which is basically a 4-channel amp and a mono amp built into one package.

RMS Power @ 4 Ohm 4 x 90RMS + 300RMS
RMS Power @ 2 Ohm 4 x 130RMS + 500RMS
RMS Power @ 4 Ohm Bridged 2 x 260RMS + 300RMS

So that will give you 500wrms at 2-ohm on the sub channel, and since the MM1240 (which is the 12" version) uses 425wrms, it will be perfect. Also give you a normal 4-channel amp for your speakers.

Create an account here, Option Audio , and bid on the OAH500, my bid for $250 was accepted (though I have no need for the amp ), and I would take OA over Jaycar any day. Also it will be a lot cheaper than the Jaycar amp.

Out of interest, why would you take OA over jaycar any day? I've had moderate use of both, and hands down would take a jaycar amp anyday. I've seen three 1000wrms OA mono's all die, been sent for repair and not heard a word back in 3 months. I have an old 4x50wrms jaycar amp (old blue with black knobs) and i've dropped it, left it out in the rain, all sorts of nasty stuff and it still works flawlessly, without any noise. What has happened to my amp is no where near normal, but still I thought it said good things about Response. Even their newer stuff seems to be keeping up with the trend.

I'm not at all having a go at you mate, was just wondering.

I've heard some bad thing about the latest range of Jaycar car audio products, just not being the quality it used to be. And on the flip-side I've talked to a few local installers and haven't heard of one OA amp coming back. But of course that could just be coincidence that none have come back to those specific installers, maybe their just lucky.

I'd still take a better brand amp any day like Steg of DD, or something but for $250 for a fairly powerful 5-channel amp just seems like a hard to pass up bargain to me.

With your old Jaycar amp, that just proves a point for any brand, they just don't make them like they used too

yeah id prefer to have a 12" in my ute just i dont think funds will accomodate for it at the moment, if i go with the 10" sub setup then later in the future when i can afford to ill upgrade to a 12" and do it all then. i know 10s dont handle the deep notes as well but in my old ute i had a ported 10" fusion tube and i was pretty happy with how it handled all my different sorts of music. but thanks for showing me all my options mate

If you ran out of phase audio into each coil you'd get virtually no sound and a lot of heat as it would be fighting itself. You run coils in phase and tuning doesn't matter as the magnetic force is just added together.

Ah, ok. Cheers for that mate.
