DD Audio 606d-D4

• 6,5″• Subwoofer• 1800W• 2 x 4 Ohm&lt p&gt 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 250-500 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.&lt br&gt &lt br&gt Features&lt br&gt EROM surround&lt br&gt High-temp, 2.0”, voice coil&lt br&gt Double Layer Deep bass, high excursion spider system&lt br&gt Unique glass fiber and natural pulp cone&lt br&gt Back plate coil gap venting&lt br&gt Extended pole piece&lt br&gt DD cast basket&lt /p&gt
