You may be better off, much less strain on your receiver that way.
I had the same problem at one time (5 VMPS speakers plus 1 VMPS sub) and an under powered receiver.
My mains were VMPS Supertowers, the lower section of these are the large VMPS subs...Why would I run them small?
My receiver had pre-out for all channels so I just added a dedicated two channel amp to drive the fronts full range.
I set the center and rears to small and let the sub deal with their deep bass...this left the receiver with only 3 channels of 80hz and above work load....sounded fantastic.
You will need to do one or the other depending on your room and speakers I would say.
