Dual Rectifier 3 channels to 2x12 + 4x12

[sulistef]

I will add ad 4x12 rectifier cab to my rig. I already have a Dual Rectifier 3 channels head and a 2x12 Rectifier Cab.
How do I have to connect the 2 cabs to use both the 2x12 and the 4x12 ? Is it possible ?
Thank you.

What is the impedance of the cabs? You can run 2 - 8 ohm cabs plugged into the 2 - 4ohm jacks on the amp, or 2 - 16ohm cabs plugged into the 2 - 8ohm jacks on the back of the amp, OR 1 -16ohm cab and 1 - 8 ohm cab with the 16 ohm cab plugged into the 8 ohm jack and the 8 ohm cab plugged into the 4 ohm jack. Hope this helps!

Thanks for these details.
I'll get my 4x12 today so I don't know at the moment the impedance but with your guidelines I should be able to connect all this.
Thank you again.
