Rockford Fosgate RNGR18-FWE 10" Ranger Subwoofer Enclosure

The Rockford Fosgate RNGR18-FWE is a vehicle-specific 10-inch subwoofer enclosure designed for select 2018+ Polaris Ranger models. It uses the under-seat location normally associated with the vehicle's 5-gallon-bucket emboss, helping add bass without occupying the cargo area. The enclosure is sold empty, allowing the system builder to select a compatible Rockford Fosgate Color Optix subwoofer separately.

This enclosure is intended for Ranger owners who want a cleaner, integrated bass upgrade than a universal box can provide. Its molded exterior is texture- and color-matched to complement the vehicle interior. It can mount under the front or rear passenger seat location, subject to confirmed vehicle compatibility.

The Gen-2 enclosure uses a vented design intended to provide stronger output than the earlier Gen-1 version. An included port cap lets the enclosure be configured as sealed for a tighter bass character. The cap is also intended for use when the UTV may be submerged.

Rockford Fosgate designed the RNGR18-FWE for use with 10-inch M1 and M2 Color Optix subwoofers, including specified M1D4 and M2D4 models. The enclosure accommodates one subwoofer with an 8.90-inch cutout and up to 4.23 inches of mounting depth. Since no subwoofer or amplifier is built in, power handling and final impedance depend on the separately selected subwoofer and amplifier.

For an integrated Ranger audio build, the RNGR18-FWE can be used as the bass enclosure within a Rockford Fosgate motorsports system. It includes a wiring harness and installation hardware to support vehicle-specific installation. Verify the Rockford Fosgate compatibility chart for the exact Ranger model, year, and seating configuration before purchase.

Design & Installation

The RNGR18-FWE uses a molded composite enclosure design with injection-molded Centrex plastic and integrated UV inhibitors. Its exterior is finished to coordinate with the vehicle interior, while the vented layout and removable port cap provide configuration flexibility. The enclosure is rated IPX6 for water intrusion and is part of Rockford Fosgate's Element Ready motorsports product family.

Install the enclosure only after confirming fitment for the specific Ranger model and seat location. Mount it using the supplied hardware and OEM mounting points, with minimal drilling required where applicable. A compatible 10-inch subwoofer, suitable amplifier, and system-level wiring or integration components are required separately; the enclosure package includes its dedicated wiring harness and mounting hardware.
