I have some RF 8" in my doors. I removed the door panels and then the speakers. I then used a heat gun to soften the enclosure and pushed the speaker into it while still soft to let it form around the speaker. 2005 GT
Which subwoofer did you put in? I have the P2D2 subwoofers. Ive got the back cut out and ready to start remolding but it is just hitting the bracket for the glass. Might need to put a spacer in.
Not really sure of the model. Bought them in 05. The only thing I needed to do was remove the bolt in the bottom of the enclosue. Otherwise they do fit snug but still within the original enclosue.
Toto, I used a medium depth 8" in the doors of my '12 and had to customize the rear of the door panel. Sounded great with no rattles, here is the link to the build if you have questions let me know.
