I think that you will like it. I have both the MM6501's and a MM1040 svc and they play rather nicely. I was running the MM1040 in my SUV and it played plenty low and loud. However, it is not quite loud enough in my Lexus because the trunk is solid metal.
I am currently running Focal 165 V30's and the MM 6501's sound pretty darn close to them after some tuning. The Focal's are just a wee bit more precise in both the tweeter and the mid range, but both sets offer excellent mid bass.
