PBR300X2

The Rockford Fosgate PBR300X2 is an exceptionally compact 2-channel amplifier from the Punch series that delivers up to 300 watts RMS despite its small size. Thanks to innovative Boosted Rail Technology (BRT), the amplifier combines high efficiency with low distortion and is ideal for space-saving car audio installations, motorcycles, and recreational vehicles.

Its compact design allows for discreet installation even in tight spaces. Thanks to the integrated high-level inputs with automatic power-on function, the amplifier can be easily integrated into existing OEM sound systems. Adjustable crossovers, the Punch EQ tone control, and bridge mode offer versatile options for customizing the sound system.
