Rockford Fosgate 24WRNGLER-STG3 12" Jeep Audio System

The Rockford Fosgate 24WRNGLER-STG3 is a vehicle-specific Stage 3 audio upgrade kit for select 2024+ Jeep Wrangler JL models. It is designed for owners who want a complete, factory-radio-retaining system rather than assembling separate speakers, amplifiers, wiring, and integration parts. The package combines amplified front-stage sound with a custom-fit 12-inch subwoofer system. Jeep-specific enclosures, harnesses, and mounting hardware support an integrated installation approach.

This system includes a pair of 6.5-inch TMS65 coaxial speakers, a pair of 1-inch M2-TS tweeters, and one 12-inch T1S2-12 slim subwoofer in a vehicle-specific enclosure. A four-channel M5-800X4 amplifier powers the full-range speaker stage, while an M5-1000X1 mono amplifier powers the subwoofer. The listed system total is 1,800 watts. The kit is engineered to work with the existing Jeep radio and retain the overhead soundbar.

For listeners who drive with open tops, doors removed, or in changing weather, the system uses Rockford Fosgate Element Ready components and enclosures. The amplifiers carry IPX6 water-intrusion ratings, while the speaker components use weather-resistant construction suited to exposed vehicle environments. The TMS65 speakers use carbon-fiber-reinforced polypropylene cones and Santoprene surrounds. The slim subwoofer adds low-frequency output while helping preserve usable cargo area.

A Jeep-programmed DSR1J digital signal processor is included to integrate with the factory CAN-bus audio system and apply a vehicle-specific tune. The system also includes a PLC2 bass level controller with a custom knob, giving the driver direct adjustment of subwoofer level. The amplifier platform provides preset tuning capability along with onboard crossover and gain-control functions. This combination is intended to simplify tuning while preserving factory source-unit operation.

The 24WRNGLER-STG3 is a comprehensive upgrade path for compatible Wrangler JL owners who prefer matched Rockford Fosgate components and application-specific fitment. Its T-harness integration is designed to avoid cutting or splicing the vehicle's factory audio wiring. A complete wiring kit, fuse block, amplifier mounting arrangement, and 12V accessory relocation kit are supplied. Confirm vehicle fitment and installation requirements before purchase, especially for trim, body style, and factory-audio variations.

Design & Installation

The system uses OEM-style speaker and subwoofer enclosures designed around Jeep mounting locations, with durable polyethylene enclosure construction and friction-welded seams. Its M5 amplifiers use Element Ready chassis construction, conformal-coated circuit boards, sealed harness connections, and IPX6 water-intrusion protection. The TMS65 speakers use carbon-fiber-reinforced polypropylene cones, while the T1S2-12 subwoofer uses a composite cone, foam surround, and die-cast aluminum frame. These materials are selected for long-term use in demanding vehicle environments.

Installation uses direct-fit mounting points, factory-style connectors, and a T-harness intended to eliminate factory-wire cutting or splicing. The kit includes the DSP, amplifiers, speaker and subwoofer enclosures, bass controller, wiring kit with fuse block, mounting hardware, and a 12V relocation kit. Some vehicles may require relocation of the 12V accessory socket, and professional installation is recommended for correct vehicle disassembly, power wiring, DSP integration, and system verification.
