Product Research


Overview: This MB Quart package includes brackets and grilles specifically designed to install aftermarket 6x9 speakers in the roll bar of Jeep JL series Wranglers and JT series Gladiators, replacing the factory speakers.

Note: Installation requires cutting and modifying the factory speaker mounting surface; the factory speakers CANNOT be reinstalled after modifications have been performed.

Mounting: The brackets are powder coated steel with a foam gasket backing. They are mounted to the roll bar using the included screws. The speakers are mounted to the brackets using the included machine screws, and the plastic grilles are mounted to the roll bar using the factory bolts (from the factory grille).

78 mm approx 3 and 1/8 inch. I mounted Alpine 6 x 9 type S
[ CHRIS  Mar 24, 2022 ]
It is stamped metal. My guess is <1/8" or <3mm.
