Hey! I own a 92 4 drs EX-R Accord and I changed the front door speakers, When open the door pannel, there is a black plastic piece that goes around the 5 1/4 " speaker. I decided to put 6 1/2" speakers but they don't actually fit in the platic case. So I fixed them there without the plastic frame and it seems the sound quality is not that good. (Between I put Pioneer 6 1/2 " speakers so it's not the speakers are broken or anything.) Behind the speaker I fixed a light plastic to prevent the contact between the speaker and the water that stays on the window.

What I'm wondering about is : Are there any Accord or Acura cars that have 6 1/2 " speakers from origin!!???

I would use this car's plastic case so the sound quality would increase.

Thanks a lot
Martin!
