Currently in the process of replacing stock non-bose blown out speakers in my 1992 JDM 2+2 RX7, and I can't seem to find any info on how to remove the rear speaker cover pieces for a 2+2. I've seen max cooper's guide on how to do the rear speakers (Rear Speaker Replacement (non-Bose)) but I'm struggling to find the third trim clip like he mentions. I don't know if I have to pull the back seat or not, or even where to begin with that if it is required. Is there a guide or manual out there to remove the rear trim of a 2+2?

 

For each side, there's two of those clips hiding behind the fold down seat. You have to remove the two bolts holding the seat belt in place as well. There's no clips that I can recall anywhere else for the 4 seater. You'll just pull the piece off, popping a number of panel clips to the body. The panel will slide up and out from between the seat as you're pulling it.
Watch for the seat belt runner for the rear seats. Those plastic pieces can fall or break on removal. Haven't quite figured out how they go back in yet. I did also unbolt the body mount for the front belts to give myself a little more room to move around, since I didnt want to pass the belt through the runner on the panel.

 

I'll give that a try. I've had the RX7 for 2 years now and I didn't find out the rear seat even folded down until 2 days ago lol. Just never crossed my mind such a little seat back would ever need that feature. Thank you
