What's everyone's opionion? I have a Memphis 500D, 2 ohm stable. Before I had 2 Memphis 10" single voice 4ohm. Should I get the DVC 10"? Is there a sound quality difference between single and dual voice coil speakers? Also, how will I wire 2 DVC 4 ohm to a 2 ohm stable amp. It cannot go to 1 ohm or the amp will clip. Thanks, Wayne. ------------- davedyer79

Not gonna happen dude. There should be no audable difference between the two types of subs. The difference is how they wire to any chosen amplifier. 2 dvc 4 ohm subs will yield only these possible combinations. 1 ohm, 4 ohm, 16 ohm. You are much better off with the single 4 ohm subs with the amp that you have.

The only advantage a DVC has over a SVC is if you have only one sub. With a DVC you are able to wire it in parallel to drop the impedance in half. Other than that, stick with SVC's, they're easier to work with.

Might be good to add that you should NOT wire DVC woofers in parallel (4-Ohm each) if you're bridging an amplifier. The amp will see a load half of the woofer, or 1-Ohm in this case. You don't want to do that unless you have a very high-current amplifier.

The answer to that is to wire each woofer with a short jumper between one coil's POS+ and the other coil's NEG- terminal. Do this to both woofers. Then wire the remaining terminals in parallel to the amp, both POS+ to POS+ and both NEG- to NEG-. This will result in a 4-Ohm load on the amp.

Thanks for the responses. I think I will stick with the SVC 10" subs. The reason I asked is that I had a guy at a very well known car electronics store tell me that DVC's will sound like 2 subs if you use both coils, and I thought that sound a little far-fetched. Maybe he was trying to sell me the DVC's so I would buy a new amp. D*#$ those pushy saleman!!

He was probably just, in fact, an idiot. ------------- Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

You can also get two dual 2-ohm subs and wire them in series/parallel and get a 2-ohm final load to the amp...this will give u 250W rms per sub with your amp...
Subs like Kicker CompVRs would thrive off a setup like this...Dual 2-ohm compvr 10s have an rms rating of 300W rms, so giving them each 250W rms would be fine.

The only reason for a DVC is for adaptability? Will a 4ohm SVC sub sound the same as a 8ohm DVC sub from the same manufacture and series if wired at 4ohm? Will it use the same amount of RMS watts? Will the ratings be different a the different ohm loads?

some charatistics will be diffrent nothing like free air resonant and sound but some parameters based on how the sub is wired will change....the eclipses I have list both parralel and series speaker prameters now thats taking time in your product

i guess his subs dont last long if he believes that u can use only one coil on a dvc sub ------------- Clarion DXZ745MP

I can vouch for those Kicker comp VRs Padawan spoke of. I have that very set up in my F-150. Its a very flexable system that can pound out the SPLs and works well as a SQ system.
