6"x9"s in AT200? Options

[dan85204]

i was just wondering if it was possible, with some modification of course, to fit 6"x9"s for the back speakers in my AT200. are there speaker mounts available? right now i have rockford power speakers 150w 75rms in the front doors, and they bump pretty good. but in the rear i have crappy pioneers that are also 150 w, but only 30 rms.

also, what would be louder (aka, bump harder) 6.5" round speakers or 6"x9"s of the same power specifications? i really like the sound of my rockfords so i'm thinking of getting those for the rear.

no sub cause i think that's a little overkill.
