Finally finished upgrading the door and dash speakers to pair with my existing 12" sub. And pioneer head unit. Mounted the amp on the back of the old subwoofer location, and the ground distribution block in the cubby right beside it. Used 9 wire cable to utilize the factory wiring. Used 8x1.5" self drilling screws for the door speakers. 10/10 sound improvement. Got the idea for the dash speakers from @jcardona1, as I know most folks just upgrade the door speakers.
4 6.5" Polk Audio DB652s
2 4" Kicker 43DSC404s
Sound Ordnance M75-4 amp
Also found out the area around the seatbelt bolt bracket on the rear passenger side was rusted, was able to punch a hole through it. My buddy and I are gonna cut it out and weld in a new piece and a nut next weekend.
