J & M 400w 2-Speaker/Amplifier - Road Glide/Ultra XXRK-400SP215RG

Stock Harley fairing speakers leave serious performance on the table—muddy mids, weak bass response, and insufficient output for highway riding or spirited acceleration. The J&M 400w 2-Speaker/Amplifier kit delivers genuine high-fidelity audio with 400 watts of Class D amplification and custom-engineered component speakers that transform your Road Glide or Ultra into a rolling concert venue. This is a true plug-and-play upgrade: no modifications, no custom fabrication, and factory-level fitment using OEM mounting patterns and electrical connections.
