I had them professionally installed and uninstalled. I did have a safety bag in my trunk that rubbed against the grey carpet on one of the bottom sides, pretty minor. I honestly could just superglue it back to the box but ill leave that up to you; LIKE I SAID PRETTY DARN MINOR. Only had them in my car for 6 months!The following specs are taken from the manufactures website. CP212-W0v3 Enclosed Subwoofer System with Dual 12W0v3-4 Subwoofer Drivers, Dark Gray Carpet (600 W, 2) - Ported Enclosure This powerful slot-ported BassWedge subwoofer system delivers awesome output at an unsurpassed value. The slot-port runs along the bottom of the enclosure and fires on the same plane as the woofers to produce excellent extension and response smoothness. The port mouth is flared to minimize air-flow noises. The ultra-versatile BassWedge shape has extended sides so that it can be placed with the woofers firing out or straight down, off the floor of the vehicle. The shape works equally well in forward or rear-firing installations. This gives you plenty of options for tweaking the loading of the enclosure into your vehicle. Finish: Dark gray, high-grade automotive carpet with "JL AUDIO" embroidery on the top edge and "Slot-Ported BassWedge" embroidered on the port mouth.
