Hummer: White H2 Leave a Comment / Audio, Custom Fabrication, Interior Lighting / By Ultra Auto Sound Hummer H2 getting a sound makeover. A simple but very powerfull sound system is going to be installed in this bad boy. For this owner its not only his 1st sound system…..but also his 1st vehicle. JL Audio 12W7 anniversary edition subwoofer in a high output enclosure custom fitted to the vehicle. Lighting installed in the enclosure to make it stand out! I still can’t believe the output you get out of one JL AUDIO W7…..always impresses me! Share This:FacebookTwitterEmailLike this:Like Loading... Related
