The PBR300X4 is a full-range 4-channel amplifier designed for stereo front/rear systems that requires little space. Rockford's Boosted Rail Technology provides an ultra efficient-design generating 300 Watts of power, and the amplifier also boasts a variable hi-level DC offset turn-on circuit for easy installation into any OEM system. Great for motorcycles and recreational vehicles.
Rockford Fosgate Punch Series Amplification
For over 25 years, Punch amplifiers have set the standard in the car audio amplifier industry and they continue to do so today. It's the reason that they have become the most popular amplifiers in the world. Each of the Punch family amplifiers reproduce sonic perfection along with impressive power in a compact chassis.

Power ratings on Rockford Fosgate amplifiers conform to CEA-2006 industry standards. These guidelines mean your amplifier's output power ratings are REAL POWER numbers, not inflated marketing ratings.
Discrete Surface MountDSM--An industry-leading manufacturing process, DSM utilizes high-speed robotics, high-quality 1% tight-tolerance parts and large board traces. The discrete components are laser etched to meet a particular value and a very low tolerance. This lower tolerance improves the efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature. These superior components are used by aerospace, automotive, and cellular manufacturers.
Dynamic Thermal ManagementHeat is often inefficiently dissipated across a heatsink causing "hot spots". This impacts important design goals, which are:
Keeping internal components cool. Maximizing potential of all components. Reducing distortion for better sound quality. Increasing efficiency to produce more power.Rockford Fosgate engineers have developed an award winning cooling design called DTM. This patent pending design seamlessly manages the output of power supply temperatures, while evenly distributing the excess heat across the entire amplifier.
MEHSA3MEHSA3 (Maximum Efficiency Heat Sink Application--gen. 3) is a proprietary process that yields up to five times better heat transfer than traditional FET mounting techniques, using the exact same components. A multi-layer insulated metal substrate operating with minimal thermal resistance spreads heat both downward & outward to quickly dissipate heat from each device across the heatsink. This process combined with our optimized heatsink designs, DSM (Discrete Surface Mount) technology and MOSFET devices, allows Rockford Fosgate to squeeze more watts per cubic inch from every output device as well as provide consistent thermal stability. The 3rd generation creates a dielectric layer between the ceramic topside and the aluminum base that retains all of the electrical isolation and capacitive coupling of the original MEHSA material increasing it's thermal conductivity. The higher power handling results in a 20% reduction in thermal impedance.
