You've sweated and laboured and now your home-made sub box is almost ready. You'll need to cover it with some nice, thick sound-absorbing carpeting to acheive that professional look and feel. Even if you didn't build it youself, you can still cover that old wooden box with something that'll look good and won't reflect sound and create echoes. In fact, you can apply this acoustic carpeting to any place in your vehicle that needs deadening.

This carpet piece from Metra measures 54" by 5 yards (180"), so you'll have plenty enough material for almost any project. Available in 3 colours: black, charcoal, and silver. Warranty: 30 days.
