615e - Designed & Engineered in the USA Overview The 600 Series is a great entry point for a higher performance system design that keeps the vehicle as close to stock as possible. These subs will perform like a boss on as little as 300-600 Watts, meaning even multiple woofer systems can be driven with one moderate powered amplifier. This keeps electrical upgrades minimal with less added strain on the vehicle. With a high energy, double stack motor paired with a laminated triple layer poly cotton spider suspension the 600 Series works best with vented and multi-order enclosures. 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.
