DD Audio Redline 612e D2 subwoofer 12" (300 mm).

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. 
The new E revision features an increased motor size, increased top plate thickness, and increased voice coil winding length.
