mb quart is nice... but the high end stuff clearly outshines the lower end stuff (which includes the 6x9s... the higher end mb quart stuff doesn't have 6x9s), but you should definately think of doing 6.5 components in a custom install in the back. crutchfield offers the conversion plate, but the hole will need some cutting to accomodate the 6.5 woofer. anyway, i had some boston acoustic rally 6x9's and loved them. they ****in kick ass and are only 200 for a set at a store.
