Stinger X X2DSP X Mat Speaker Kit 1.7 sq ft

The aluminum outer layer made it easy to press into the tight corners of my trunk, and the self-adhesive backing stuck firmly on the first try. Took about an hour to cover the rear deck, and the whole car feels noticeably quieter on the highway now.

My door panels used to rattle like crazy on bass-heavy tracks, but the aluminum outer layer on these mats really stiffens things up. I covered the firewall and one door with the 1.7 sq ft and it's a night-and-day difference for the cost. Cut easily with a utility knife and the self-adhesive held fir

The adhesive stuck well and the aluminum layer feels sturdy, so it went on my door panels without much fuss. It's just not as thick as I hoped for a 1.7 sq ft kit, and I needed two packs to really make a difference on the floor. Works fine, but I expected a bit more coverage for the price.
