If you think your Yamaha YXZ already sounds good, the Rockford Fosgate YXZ-STAGE4 Stage 4 Audio Upgrade Kit is here to completely change that experience. This is a full 1,800-watt high-output system built to outperform factory audio by a huge margin, giving you loud, clean, and immersive sound even when the terrain gets wild. It’s a fully integrated multi-speaker setup too, combining front lower speakers, rear tower speakers, dual subwoofers, tweeters, and multi-channel amplification to create true 360-degree sound coverage that fills your entire ride instead of just one direction.
At the core of this system is high-power Class AD amplification using T400X4ad technology, designed to deliver strong, efficient output with low distortion and smart thermal control so it stays consistent even when pushed hard. The Yamaha YXZ-specific DSP integration takes it further by pre-tuning your sound profile for off-road acoustics, giving you better staging, clearer vocals, and deeper bass without needing endless manual adjustments. You also get advanced audio controls like EQ presets, Punch EQ, crossover tuning, and gain control so you can fine-tune everything exactly how you want it depending on your ride and environment.
This kit is engineered for real off-road abuse while still keeping installation clean and factory-like. The PMX-2 marine-grade head unit is built to resist UV, water, dust, vibration, and corrosion so it keeps performing no matter how rough things get. Installation is made simple with the RFYXZ-PMXDK dash kit and pre-wired harnesses that plug directly into OEM points, eliminating complicated modifications. You also get a dual subwoofer system with a 10-inch marine-grade sub in a sealed fiberglass enclosure for deep, controlled bass, plus RM1652 6.5-inch speakers and 1-inch LCP tweeters for crisp highs and balanced mids. Add in rear roll-bar tower speakers for full open-air projection, and the Element Ready construction that stands up to mud, heat, and vibration, and you get a system that sounds massive while still looking like it came straight from the factory.
