D Series (Mini) 4-Channel Amplifier
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 180 watts. 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.
