DESC: 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.
