Put some Punch in your system
Rockford Fosgate's RFPEQU universal Punch EQ restores the sparkle and impact to your music that road noise usually covers up. Developed over thirty years ago for their popular Punch amplifiers, Rockford Fosgate now brings you this handy remote EQ system in a universal, stand-alone version that works with almost any aftermarket car amplifier.
It's a line output converter and a high-voltage line driver, too
This 2-channel treble/bass booster accepts either RCA or speaker-level inputs, so you can use it with your car's factory receiver. Whether taking a low- or high-level input, the RFPEQU creates a hefty output (up to 10 volts), guaranteeing a strong and clean signal for your amplifier to handle.
