12ft X 45" Blue S35 Polymat Speaker Box Carpet & Trunk Liner – 15in Grill Size

Ready to wrap that custom sub box?

This is a 12-foot long roll of blue S35 Polymat carpet, specifically made for speaker boxes and trunk liners.

It's 45 inches wide, so you've got plenty to cover even a big enclosure.

The 15-inch grill size marking means it's the right stuff for standard speaker grilles.

It's the same material pros use to give boxes that factory-finished look.

Grab a roll and make your system look as good as it sounds.
