One of the most exciting products to hit the Hummer market in the last year! This is a complete "turn key" sound system from the leader in car audio, Rockford Fosgate. The Rockford Fosgate Punch sound system will transform your Hummer into a mobile explosion of sound. The system installs in under an hour and comes complete with a custom enclosed Sub, new mid's and hi speakers for the front and a base punching amp built into the enclosure. Best of all, the system retains the factory interior room by being located under the rear seat. Backed by Predators Industry Leading 4year/50,000 Mile Warranty.
