Rockford Fosgate RZR14RC-STAGE4 Stereo Kit w/ Speakers & Sub - Full

In this review of the RZR14RC-STAGE4 kit, the bottom line is simple: this is a complete, no-drill audio solution for Polaris RZR owners who want full system sound while retaining Ride Command as the source. The kit combines a Ride Command interface harness, four full-range speakers, a 10in subwoofer in a vented enclosure, and a 400 W four-channel marine amplifier into a single package that installs with direct connect wiring harnesses. It is aimed at riders who need a weather-tough system that integrates without sacrificing passenger or cargo space.

Key Features

• No drilling or cutting required: The kit installs using purpose-built enclosures and mounting hardware so the vehicle body remains intact and installation is faster.
• Direct connect wiring harnesses: Harnesses made for RZR models simplify hookup and preserve the Ride Command source without complex rewiring.
• Element Ready design: All speakers, sub and amp are built to withstand harsh outdoor conditions for off-road use.
• Space-saving enclosures: Front and rear speaker and sub enclosures integrate into the RZR without losing passenger or cargo room.
• Complete amplifier and wiring kit: The included TM400X4ad amplifier and RFRZ14-K4 wiring and mounting plate deliver clean power and a tidy installation.
• Ride Command compatibility: The RFPOL-RC34 adaptor lets riders keep the Ride Command head unit as the active noise reduction aware source.

Who It's For

The Stage4 kit is ideal for Polaris RZR owners from model years 2014 through 2019 who want a full factory-like audio upgrade that resists water, dust, and UV exposure. It suits riders who value a single integrated system that uses the existing Ride Command platform rather than replacing the radio.

Riders who prefer a custom system with separate component speakers, or those looking to retrofit non-listed RZR years or other UTV brands, should look elsewhere. This kit is purpose-built for compatible RZR models and works best when maintaining Ride Command compatibility is a priority.

Pros

• Full system package with amplified power and a dedicated 10in sub for improved low end.
