I was thinking about

Two DVC 4 ohms in series and one series dvc 2 ohm subwoofers?

Will this be 4 ohms?

I have two already iam wanting a third and the amp is a 2 channel.
So when bridgeing it i can go no lower then 4ohms!

 

Can't be done. With the 4 ohm coils, your only options are 2 or 8 ohm. With the 2 ohm coils, 1 or 4 ohm are your choices. On top of that, since the subs are different impedances, to the distribuiton of power will be different. Since the amp is not 2 ohm stable, you are stuck. IMO, keep what you got or get a 2 ohm stable amp and add 2 more 4 ohm DVC's. At least with that combo with 4-4 ohm DVC's, that will give you a 2 ohm load.

 

man just run the thing at 6 ohms. all the subs wired in parallel then link all the subs in series to your amp. less power but not really a huge problem. If you think you need more you could wire all the subs in series and then parallel to your amp that would be 2.66666 ohms. Youd be pushing the amp but it shouldnt break on the first attempt.

 

Woofer wiring wizard....select how many subs and what ohm voice coils and it will show you the wiring diagrams and the ohm load for the setup. Very easy.
