Carpet underlay ?

Or you can save yourself some shipping and go to a local stereo shop... they have it. I bought a box that was enough to do the entire floor of my Duster for~ $100. Summit also sells the trunk kit too. And get some for the divider between the backseat, and some for the doors and the firewall. :lol:
My car is so loud a stereo would be useless. :twisted:
