I would definitely go with the matte finish it will be more subtle and match nicely with the interior panels. sorry i took so long been busy with school work and getting the car ready for winter.

Hey Bud,
Thanks for the support. I need your opinion, due to the removal of the carpet liner during the build the boxes will not fit with the liner in place, which is no big deal to me, I hated it anyway. My question to you is, I plan on making a flat panel traced out to fit the exposed area(if you look at the liner it will be basically the same without the areas under the boxes) I'm almost 100% positive that I want to cover it with 3M carbon vinyl, my question to you is should I go with a matte finish to match the interior panels or gloss to compliment the finish on the boxes. I'm not saying my choice until I hear what you have to say.
Regards,
Tom
