D SERIES (MINI) 4 CHANNEL

Overview

The D4.75 is a mini chassis amp designed to make space constrained installations a breeze. Don’t be fooled by its small stature; in 4 ohm bridged mode this little powerhouse can produce over 2 x 180Watts. It also features a conformal-coated PCB for added moisture and dust protection in harsh environments; making it perfect for motorcycles, UTVs, and boats.

All controls and connections are located on one side for ease of installation in motorcycle fairings, dashes, under seats, behind seats or in consoles.

Any DD Audio Product bearing the Marine Grade logo incorporates water resistant features enabling it to be used in applications where moderate exposure to moisture will not result in damage to the product.

Marine Grade products are not waterproof, and submersion or excessive moisture exposure may result in product failure. DD Audio Marine Grade products are not certified for saltwater environments.
