I have a pure JL system, and while I myself can't handle those 2 models due to the small size of my current main vehicle (Z4), I will offer that I am told by numerous audio-nuts that the W6v2 still holds more respect for overall performance than the newer W7. That is purely opinion, formed from gathering opinion of multiple other owners of both products. Take it for what very little it's probably worth. For me in my little crackerbox, I'll stick with 10w3v2...heh...
