i don't understand your question. i thin kyou can run the sub with the amp you have. if you don't have the amp, i would look into the monoblock amps i was talking about earlier.
just out of curiosity, why are you trying to run the w7 (one of the higher end subs) with an MA audio (not too high end)? no offense of course. you are free to do whatever. i just htink the 2 does not pair up so good.
