CEA-2006 Compliant Power ratings on Rockford Fosgate amplifiers conform to CEA-2006 industry standards. The Punch 300-10T is a self-contained subwoofer enclosure with built-in amplifier. This "all in one" solution is great for systems that need extra Punch on the low-end of the frequency spectrum. The 10" high output subwoofer is impedance optimized for the built in 300-watt class-D amplifier that features a low-pass crossover, bass EQ and phase switch. The enclosure can be connected via speaker level inputs for connection to factory systems, or traditional line level inputs for aftermarket systems. It also features an intelligent auto turn-on/off circuit that eliminates the need for a separate turn-on wire. The enclosure itself is precision designed and constructed using MDF (Medium Density Fiberboard) for the best acoustical properties and covered with heat activated vinyl finish to resist marks.
