well, you have to make a new baffle for it but that's recommended any time you put a new speaker in, whether it be a 5 1/4" or a 10" (I know a close friend that has 10's in his doors, in a trailblazer SS). The new baffle helps reduce vibration, and gives the speaker a much better resting place than the junky plastic piece. It would take a novice about half an hour to figure out how to make a new piece fit in there, and mount an 8" midbass driver. I know, because I was a novice:coolthumb:
Now, an 8 inch subwoofer, not going to fit most likely, but a midbass driver, without a doubt!
I am using these ones, my close friend is using these ones.
All behind the factory door panel with a new baffle. The tens play so low, when I first heard his truck, I thought the subwoofer was playing... It wasnt.:burp:
