Rockford Fosgate 800.4
The MOSFET power supplies in Rockford Fosgate's Punch 800.4 four-channel amplifier send power screaming to all the speakers in your system! At the same time, the combination of proprietary technology and clean circuit design give you a sparkling, detailed performance.
Built-in high-pass/low-pass crossovers let you tweak your tunes to work with your vehicle's natural acoustics. Punch Bass provides up to an awesome 18 dB of boost at 45 Hz for all the low-frequency slam you'd ever want.
