Ok, so I went and got new speakers for my whole car.

I got some 6.5 Kicker KS 6502s for my rear deck, 5.25s for the front doors, and 6.5 Kicker KS 65s for the rear doors.

They were all installed and I found out that my front doors had 4s instead of the 5.25s but the shop squeezed them in anyways.

I had the rear deck done first and I noticed a bit of a rattle on some songs with deeper bass and I figured that it could just be an issue with something touching the speaker and getting rattled, but after the rest of the speakers were installed there was a bit of rattling from one of the tweeters so I think it might just be an issue with the amp or something but I'm not too sure.
