About the MB Quart JC1-169SB

Take to the (off) road with better sound
Take to the (off) road with better sound
It's fun tricking out your Jeep for tooling around town or going overland. But before you start bolting gear onto the outside, why not improve the audio inside? MB Quart makes it well worth your time with their JC1-169SB 6"x9" coaxial speakers. Specifically designed for your Jeep's sound bar, these speakers come with vehicle-specific mounting plates and OEM replica grilles for a factory look. After some cutting (template included), you can bolt these speakers right into the sound bar of your Jeep in place of your factory speakers. But that's where the similarity ends — the paper/mica woofers and magnesium tweeters of these speakers kick out sound that'll make you realize exactly what you were missing before.
Plug 'em in
The speakers come with factory-compatible plugs — no splicing required. MB Quart provides vehicle-specific instructions to eliminate the guesswork, too.
Installation Note: This installation does require cutting, and you will not be able to reinstall the factory speakers. If you don't have experience with this type of project, please consult a professional.

Features
Overview: This MB Quart speaker package includes 6x9 speakers and brackets/grilles specifically designed to replace the factory speakers in the roll bar of Jeep JL series Wranglers and JT series Gladiators.
Note: Installation requires cutting and modifying the factory speaker mounting surface; the factory speakers CANNOT be reinstalled after modifications have been performed.
Basket: The speakers feature PA66 composite (plastic) baskets, reinforced with 30% glass fiber.
Tweeter Phase Lens: The phase lens can be removed from the front of the tweeter, narrowing its dispersion pattern. This is useful when the tweeter is pointed directly at the listener.
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).

Huge difference in sound quality and level of bass! Very pleased with the overall improved sound and well worth the expense and effort to install. The cutting is a bit tricky but really not that difficult if you take your time. So impressed I ordered the matching dash speakers as well!
