Series 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.
