Ultimate Premium Sound Package

Cut through the wind and engine noise with the Diamond Audio DA1423SGSP2R, a premium, all-in-one audio powerhouse engineered specifically for the Harley-Davidson rider. This high-performance kit is the ultimate "bolt-on" upgrade, designed for a seamless, plug-and-play installation that preserves your bike's factory look—no drilling, no cutting, and no compromises.

At the heart of this system is the MICRO2V2 Class-D amplifier, pumping out a massive 500W of total RMS power. It’s paired with MP652 6.5" coaxial speakers featuring high-end Horn tweeters. The result? 250W RMS per channel of razor-sharp, studio-quality sound that stays crystal clear at highway speeds. It also includes MSHD14 media receiver for an all-out performance and upgrade.

Built for the long haul, this kit is fully armored against the elements with UV-stable and water-resistant components. Whether you’re cruising the coast or tearing up the interstate, the DA1423SGSP2R delivers the sophisticated, high-fidelity soundtrack your Harley deserves.
