I would say that using a 6.5" Dyne instead of a 9" Morel is kinda silly...but if you are really on the Dyne wagon, I have a used set of "MW170GT" (that's not the PN, but it explains exactly what it is - the stamped-frame 8" from the Dynaudio Volvo OEM systems - and NOT the VW systems). If you want to see if you can get a set new from a Volvo dealer, they are the only Dyne option I know of, and if you want to check out these used ones, I will send them to you cheap. PM me your email and I will send you pics.
