I have some dual voice coil subs that are 2, 4, and 8 ohm compatable. I was just wondering what are the advantages/ disadvantages to wiring them each way. I have a Sony 760 Watt Xplod Amp. It puts out 150 x 2 RMS at 4 ohms. I have 2 Audiobahn 500 watt RMS 12" subs product number AWC12X. I was just wondering how I could hook these up to get the most power/sound quality. Could you please explain how to wire it also?

The amp probably isn't stable for a 2-ohm mono load, so the most power you will get is using the amp in the 150x2@4ohm mode. Wire each driver's voice coils in parallel, then wire each driver to right and left side of the amp. Sound quality is not affected by wiring methods or power.

If the sub is stable for a 4ohm MONO load (which I'm almost positive it is, post the model number so I can verify), wire them like so: (1) On each sub, wire the voice coils in parallel. Connect the one of the (+) leads to one of the (-) leads on the same speaker. Now, each sub will have an impedence of 8ohms. (2) Wire the subs in parallel to the amp in bridged mode. The positive lead on the amp should go to the positive lead still left open on each sub. The negative lead on the amp should go to each open negative left on the subs. (3) The subs are now making up a single 4ohm impedence circuit. This should draw the most power out of the amp. Theoretically, each sub should be receiving 300w. (4) Make sure you're running your amp in bridged mode. Check the manual. You usually use a single positive lead and a single negative lead on the amp. It converts two separate channels into one channel. (5) Enjoy your subs!!!

How can you tell this guy how to wire up his sub when you don't even know the ohm that the sub is? Maybe I missed it somewhere but all he said is that they are 2,4 and 8 (Something like that) compatible, but that doesn't tell you the actuall ohm that the sub is. I can wire two 4hm subs to get each of those loads but if i have 2 2ohm subs you have to wire them differntly to get the correct ohmage, right? maybe i missed some information but that is what I am getting out of this.

In order to be wired in either 2, 4 or 8 ohm loads, they have to be both 4 ohm VCs. Your options are wiring the 2 vcs in parallel (2 ohms), series (8 ohms), or using 1 vc (4 ohms).

---chris Don't worry. I'm not just pulling this out of my a$$. They're dual 4ohm voice coil subs. Here's the link: Audiobahn AWC12X BTW, I also own a pair of the 8" version of these subs that will be hooked up in the aforementioned configuration to my amp (eventually if I ever get myself in gear  ).

---chris You can't get a 4ohm mono load with a pair of 4ohm SVC subs. It would be a 2ohm mono load wired in parallel, or an 8ohm mono load wired in series. You would get a 4ohm mono load by wiring the 2ohm SVC subs in series, or a 1ohm mono load wired in parallel. I've just got to say that whatever you're wiring up to your amp, make sure that it can handle it. An important thing to remember that many novices don't know is that bridging your amp effectively halves your ohm load. Each channel "sees" half of the load. Hence, a 4ohm mono load is equivalent to a 2ohm stereo load. I know, I know, my "terms" aren't 100% accurate, but they're easier for the novice to understand. Well, that's if anyone is following my rambling...

I was wondering where you have been. Nothing like a good DVC post to pull you out of the woodwork!
