thanks for the input, ended up getting a pair of spacers from patrick at subaru audio for the 6.5s in the front. now I'm turning my focus onto the rear, and i was considering picking up polk db521 5.25s but it appears the cut out on them is above the 4.6" stated above so I guess I'll have to look into a different pair. In regards to adaptors for the rear, is that something I would have to custom fab or is there somewhere to pick those up?
