are you driving two different sets of subwoofers?

I suppose you CAN, but you're gonna have one hell of a time matching the output levels...

Will it work? Yes. Is it correct? No.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

This is a two-channel amplifer, which means left and right. A speaker on your left and a speaker on your right. While loading the amp with the two different impedences will not cause harm to the amp, it will, however, cause the 2 ohm side to be louder than the 4 ohm side. This is not normally done. Normal is to run a matching pair of speakers or a subwoofer bridged across both outputs.

This amp will power a pair of front components at 4 ohms, or a pair of subs (or just one sub) bridged at 4 ohms.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Use the MTX 5500 subs with this amp. Leave the 9500 out of the picture altogether. If you want to use the 9500, get a mono amp for it and leave the 5500's (and this amp) out of the picture altogether. This amp is manufacturer-rated much higher than its capabilities, so don't believe that you have to add enough subs to use up all those watts. (!!!) Get the picture? Use one type of sub, not a mixture of subs.
