Nope, it is not possible for two reasons:

1) Channel A and B refers to left and right. Since the amp is a pro model, left and right are not the usual conventions used, but it simply means Channel A = Right and Channel B = Left.

2) Your amplifier has a minimum rated impedance of 8 Ohms. If you try to connect two pairs of 8 Ohm speakers, then the connected impedance will be 8X8/(8+8) = 4 Ohms. Your amplifier could be damaged by a 4 Ohm load.

Might need to correct this Dave (my italics)😉

Oh, right - I see my grammar error.

 

EDIT:  I had also misunderstood how they were hooked up - they're parallel (I had thought series).

 

We also didn't know the amplifier was only designed to drive above 8 ohm loads.....  so I think we need to walk this back a little bit, sorry.

What will happen if I set them up like that ?

Ignore most of my previous advice.

 

Don't hook them up like you have.    You amplifier isn't rated for the extra load .... and even if it was, like I said before - these cubes are going to be swamped by the bass frequencies, and it will likely hurt their cones (no smoke fro the speaker, but torn cones and bad sound).
