I should have paid more attention to it when I had the door panels off to install the Tempo comps.

Just having left the Civic's stock door panels intact, I noticed the holes in the panel in front of the speakers have a lot of plastic filling a good portion of the holes from when the panel was molded.

I don't feel like pulling the panels off, so hoping either with drill bit taped to prevent going deep hitting the speaker, or a heated up needle to open 'em up.

I just wonder or hope there will be a noticeable difference after doing so.
