Description
The MB Quart MBQJ-48CRGB is a vehicle-specific rear overhead soundbar for 2018–2023 Jeep Wrangler JL and 2020–2023 Jeep Gladiator JT models. The composite enclosure contains four 8-inch coaxial speakers with integrated RGB lighting and translucent grilles, creating a complete rear-stage upgrade without requiring a separate loose speaker enclosure.
Each coaxial speaker is rated for 70 watts RMS and 140 watts peak power, with 92 dB sensitivity and a published response from 25 Hz to 22 kHz. The system is intended for compatible JL/JT roof mounting and should be powered, fused and wired according to the amplifier and vehicle installation requirements.
