Rockford Fosgate 20GLADR-STG5 Jeep Gladiator 10" Audio Kit

The Rockford Fosgate 20GLADR-STG5 is a vehicle-specific complete audio upgrade for select 2020–2023 Jeep Gladiator JT models. It replaces key factory-system components with amplified speakers, dash tweeters, subwoofers, custom-fit enclosures, wiring, and signal processing. The package is designed for Gladiator owners who want a coordinated upgrade while retaining the factory radio.

This Stage 5 kit combines four 6.5-inch coaxial speakers with two 1-inch dash tweeters to improve front and overhead sound coverage. Two 10-inch shallow subwoofers in a Jeep-specific enclosure add dedicated low-frequency output. The system uses separate four-channel and mono amplifiers, with a combined published system rating of 1,800 watts.

A Jeep-specific DSP and preset amplifier configuration are included to integrate the system with the factory source unit. The amplifier setup guide states that the included amplifiers are pre-tuned for factory radios, so manual adjustment is not needed in the intended installation. If an aftermarket source unit is used, input-level setup should follow Rockford Fosgate's C.L.E.A.N. procedure.

The kit uses Rockford Fosgate Element Ready components intended for exposure to water, dirt, UV, vibration, and outdoor conditions common to open-air Jeep use. OEM-style speaker and subwoofer enclosures help the installation match the Gladiator interior. The package also includes a bass-level control, complete wiring kit with fuse block, jack-relocation kit, and 12V-relocation kit.

This is a full-system solution rather than a single-speaker upgrade, making it suitable for owners who want amplified full-range sound and integrated bass in one matched package. Its plug-and-play harnesses and factory-style connectors are intended to reduce the need for cutting vehicle wiring or interior plastic. Confirm vehicle, radio, and screen compatibility before purchase, particularly for Gladiators with larger factory displays.

Design & Installation

The 20GLADR-STG5 is built around vehicle-specific enclosures and Element Ready audio components. The TMS65 coaxial speakers use carbon-fiber-reinforced polypropylene cones and Santoprene surrounds, while the shallow T1 subwoofers use carbon fiber/PMI/glass-fiber cones, aluminum dustcaps, and die-cast aluminum frames. The amplifier chassis and electronics are designed for rugged, outdoor-oriented installations.

Installation is intended for select 2020–2023 Jeep Gladiator JT vehicles using the factory radio and supplied plug-and-play wiring. The package includes a DSP, fuse block, bass-level control, complete wiring kit, factory jack-relocation kit, and 12V-relocation kit; installation has been listed as intermediate difficulty with an estimated 6–8 hour installation time. Verify the compatibility chart before ordering, as fitment information lists the 12-inch factory screen as not compatible.
