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.

300 Watts in an Ultra-Compact Amplifier
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 Mount
DSM--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 Management
Heat is often inefficiently dissipated across a heatsink causing "hot spots". This impacts important design goals,
* 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
MEHSA3 (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

In the early 70's, Jim Fosgate studied the acoustical properties of automobiles. Utilizing a real-time analyzer and
pink noise, he would graph out the acoustical characteristics of each car he tested. Jim discovered three problems that
were common to all cars:
* A midbass hump between 100-275Hz
* A steep roll-off of high frequencies from 2kHz up to 20kHz
* Reduced bass response below 50Hz
The Punch EQ on-board equalization circuit helps correct for these acoustical deficiencies in the listening
environment. When set to Low-Pass(LP) operation, it becomes a variable Bass Boost. When set to High-Pass (HP) operation,
it acts as a variable Mid-Bass and Treble Boost. When set to All Pass (AP) operation, both Bass and Treble frequencies
