All-in-one awesomeness
Upgrading the stereo in your Jeep Wrangler or Gladiator doesn't have to involve replacing the factory radio. This all-in-one speaker upgrade kit from MB Quart lets you boost your sound while keeping the stock radio. The package includes speakers, two amplifiers, and a vehicle-specific interface that's designed to work with the Jeep radio. Installation involves basic hand tools.
Big-time sound and a factory look
This 6-speaker, 400-watt system includes two 3-1/2” full-range dash speakers, two 6-1/2" mid-bass drivers in enclosures for the knee panels (lower dash), and two 6”x9" full-range rear speakers. These all-weather speakers get the power they need from two 200-watt Class D marine-rated amplifiers, and they'll sound great in your Jeep.
Built to last
The entire system is designed to blend right into your Jeep's interior. In addition to the Jeep-specific front speaker enclosures, the package includes a powder-coated mounting plate for the amps. And all of the gear is designed to meet MB Quart's exacting standards for durability and water-resistance.
Installation Notes: Installing the 6-1/2" speakers in the lower dash is not difficult, but it requires significant dash disassembly. Installing the 6"x9" speakers in your sound bar requires 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.
