JC1-169SB* [Used]

The MB Quart JC1-169SB is a direct-fit 6x9 inch rear soundbar speaker kit built specifically for the 2018-and-newer Jeep Wrangler JL and 2020-and-newer Jeep Gladiator JT, replacing the factory rear speakers with OEM-matched grilles and vehicle-specific wiring. A 1 inch magnesium dome tweeter with a removable phase lens handles the highs, rated 45 Hz to 23 kHz at 86 dB sensitivity with a 6 dB high-pass crossover keeping bass out of the tweeter's path. Each speaker handles 220 W peak (110 W RMS), enough headroom for open-air Jeep driving where road and wind noise compete with the stereo. The plug-and-play harness matches the factory connector, so installation is a straightforward swap with basic hand tools and no wire splicing or cutting into the factory harness. Because the grille is matched to the OEM soundbar shape, the finished look stays factory-correct instead of showing an aftermarket gap around the speaker.
