Description



Diamond Audio DHDMCA

Upgrade your factory motorcycle audio system with the DHDMCA – 1998-2013 Harley Davidson Speaker Adapter Ring 5.25" to 6.5" from Diamond Audio. This precision-engineered speaker adapter ring kit allows you to seamlessly install larger 6.5-inch speakers in place of the factory 5.25-inch speakers on select 1998–2013 Harley-Davidson models. Designed for a clean, factory-style fit, the DHDMCA makes it easy to enhance sound performance without compromising your bike’s original appearance.

By upgrading to 6.5" motorcycle speakers, riders gain improved midbass response, increased output, and fuller overall sound compared to stock 5.25" speakers. The DHDMCA Harley speaker adapter rings provide a secure mounting solution, ensuring proper alignment and stability even in high-vibration riding conditions. Ideal for Road Glide, Street Glide, Electra Glide, and other compatible Harley touring models, this kit simplifies installation while preserving the factory Harley-Davidson look.
