Rockford’s legendary Punch Series amps have been continually relied upon to deliver ultra-clean power to everything from mild to wild systems for more than a decade. By drawing on the feedback they receive from hardcore car audio competitors, Rockford has continually improved their Punch amps to offer more reliable power and better sound quality. Rockford’s Trans-ana (TRANSconductance Active Nodal Amplifier) MOSFET circuitry simplifies the current and voltage gain. Punch amplifiers feature discreet surface mount technology (DSM) utilizing high-speed robotics to produce circuit boards that are more efficient, put out more power, and are less prone to unwanted noise. The Punch series comes with Punch Bass, a remote operated bass EQ control that helps correct for missing low bass output in the automotive sound environment without adding excessive boost. The supplied remote level knob can be installed anywhere for easy tuning. Punch series amplifiers feature a 12 dB/octave slope crossover, variable between 40-400 Hz high-pass or low-pass. The completely redesigned, extruded heatsink has a sleek, high-tech look and features a removable front shroud that covers all connections for a clean, finished appearance. The top-mounted, brushed silver logo adds a touch of class, while 3 LED indicators let you know the status of your Punch. Hand crafted in the USA.
