So ive got 2 atlas 12s and they have that odd dvc setup (1 4 ohm coild and 1 2 ohm coil). i remember reading that u shouldnt wire the amp directly to the 2 ohm coil. what id like to know is, what are the various ways to wire up a pair of these subs. like what final ohm loads can i achieve and how do i wire them to achieve this. if u cant wire the 2 ohm coils by themselves, is it possible to wire them along with the 4 ohm coils? all this time ive only been wiring the subs at 2 ohms for 2 subs or 4 ohms for one sub just using the 4 ohm VC.

i had mine running by putting the 2ohm coils in series (so they are essentially a 4ohm connection) then running it in parallel with the other 4 ohm coils, for a final load of 1.33333

i've also heard that you can run the 4 and 2 in series, so you could run then at a final load of 3ohm as well

that 1.333 load is what im looking for. im not picturing very well how u did this though. would u mind dumbing it down for me and let me know which wire goes where?

also, it should be noted that im running them in 2 separate boxes. im pretty sure i wont be able to achieve the 1.33 ohm load this way. if there is, please inform me.

It was actually a cool design that we came up with for that sub... but most simply didnt get what could be done with it.

In your case, you would hook up both of the 2 Ohm coils in series with eachother. This would yield a "3rd" single 4 Ohm load. By series I mean take the + from one 2 Ohm coil and call this the + side of the "3rd" coil. Take the - from the other subs 2 Ohm coil and call this the - side of the "3rd" coil. Then hook the remaining + and - from the coils together with a jumper. This effectively sums both of the 2 Ohm coil to act as a single 4 Ohm coil.

Then taking all "3" of these coils you would wire all positives together and to the amp, as well as the negatives. These are now being wired in parallel (which effectively divides the common load by the number of coils... 4Ohms / 3 coils = 1.333 Ohms)

Let me know if I can help with anything else.

is what youre saying even possible given my situation of having them both in separate boxes?

just put a set of terminals on each box for each coil...and be sure to label them

No reason why it wouldnt be... Like Vladd mentioned, simply use separate terminals on the outside and make sure you keep them straight
