I know lots of people have been wanting to put subs in there rearselfs so i thought i would share. i took on the challenge of putting a 8 inch in. I have it all wired and used a dremel to widen the 6by9 hole to fit the 8 inch. i put a Pioneer TS-SW841D that fit with plenty of room and when i did a test run it gave plenty of bass without a encloser. i with post pics later..
