Description:

This Rockford Power Series T1D412 Dual 4 Ohm subwoofer features cutting-edge Rockford Fosgate technologies. With patented VAST technology, the T1D412 increases surface cone area by up to 25%, delivering the performance of a much larger woofer. Capable of handling 1600 watts, it provides powerful, warm bass from a virtually indestructible cone reinforced with Kevlar fibers used in bulletproof vests. The subwoofer's hard anodized aluminum dust cap protects the cone and showcases the Rockford Fosgate logo. Its FlexFit basket offers flexibility for extreme installations, while the SWIFT terminals allow easy impedance selection between 2 and 8 ohms, making future upgrades simple. This subwoofer combines high-tech design with powerful performance to enhance any audio system.
