Flashing tape inside a sub enclosure?

[fixinit]

Following up on this week old thread. Somehow the tape tightened things up. I also added a little more poly-fil to the enclosure and made sure to staple it so it wasn't so poofy and not restricting the port. In addition, I made sure things were tightened down in the rear of the car's cabin so I get less rattle and vibration. It's amazing how better a sub in the trunk sounds while in the front seat when harnesses and trim is fastened down. Next step is to line the bottom of the trunk with this tape and clean up my exterior spoiler contacts. Good times!
