ok this has gotten me into a contemplation. i have DVC MA audio 12"s D6..wiring subs -- posted image.it says there that this is a DVC sub which if it was: If using Dual 2 ohm coils the total load would be 4.0 ohm.
If using Dual 4 ohm coils the total load would be 8.0 ohm.
If using Dual 6 ohm coils the total load would be 12.0 ohm
wiring subs -- posted image.   this is the way i have my subs wired up right now to my amp(to get 6ohms). my amp can only do 2 ohm stereo, but i have these subs bridged on my amp.
wiring subs -- posted image. now another one is that this one is a SVC sub: If using Single 2 ohm coils the total load would be 2.0 ohm.
If using Single 4 ohm coils the total load would be 4.0 ohm.
If using Single 6 ohm coils the total load would be 6.0 ohm
this is really confusing cause essientially can i wire up my subs like this wiring subs -- posted image. but take out the wireing that connects the voice coils so they would be wired only as SVC to get a 3ohm load. would that be possible?!

Your speaker has dual 6-ohm voice coils.  The only two setups for this speaker are 12 ohms (in series) or 3 ohms (in parallel.)  I recomend that if your amp can handle a 3 ohm load when bridged wire it in parallel.  DO NOT wire just one voice coil to your bridged amp.  If the amp is stereo and cannot handle a 3-ohm bridged load, you could connect each VC independently to one channel, as long as you are sending a mono signal split into both channels.  This would place a 6-ohm load on each channel.

I just read another of your posts.  Do you have two of these woofers?  Then you have more wiring choices.  The total load you can place on your amp with two D6 woofers is either: 24 ohms, 6 ohms, or 1.5 ohms. 

From your amp description (2-ohm stereo stable, which means 4-ohm briodged stable) I suggest you wire each sub with the voice coils in series (12 ohms each) and put these two in parallel at your bridged amp (6 ohms on the amp).  Any lower load will potentially damage the amp.

Please give complete information, including make and model when you can.  Thanks.
