The Punch P8004 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 40-400Hz high- or low-pass. The completely redesigned, focused mass die-cast heatsink has a sleek, rounded shape and features a removable chrome shroud that covers all connections for a clean, finished appearance. The top-mounted, illuminated RF logo even features built-in output meters for a little bling with your raw power. minimize
