Differential Inputs

     Differential inputs eliminate noise picked up by signal cables.

Differential input circuitry measures the voltage of both the (+) and (-) input signal. The circuitry subtracts the voltage common to both conductors (noise) resulting in only the clean signal. This allows only clean signal to enter the amplifier.

MEHSA³

MEHSA³ reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span.

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 impedance.

Class-BD

U.S. Patent 6,097,249

Class-bd amplifiers have 75-80% efficiency ratings vs. 20-60% efficiency ratings of traditional class A/B amplifiers.

Rockford Fosgate bd topology is a revolutionary patented design (#6,097,249), integrating a technology that is more efficient than typical class AB and has lower distortion than class D designs. POWER bd amplifiers are 75-80% efficient vs. 20-60% efficient class ab amplifiers. What does that mean... It means, more power from your amplifier with less drain on your vehicles electrical and charging system.

DSM

DSM utilize 1% tight-tolerances improving efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature.

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.

Punch Bass EQ

Pioneered by Jim Fosgate in the early 70's, Punch Bass compensates for acoustical problems common in all cars.

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. This lead to the development of the Punch Eq to compensate for problems that were common in all cars. The Punch Bass EQ section of the Punch EQ up to 18dB of boost for correcting acoustical deficiencies.

Constant Power

U.S. Patent 7,994,857

This provides the ability to instantaneously deliver maximum output power to speakers without regard to its varying impedance while maintaining high-efficiency and thermal performance.

Music and speakers have a dynamic relationship. As the frequency of music varies, so does the impedance of the speaker. This patent pending technology gives the amplifier the ability to instantaneously deliver its maximum output power to the speaker without regard to its varying impedance while still maintaining its high-efficiency and thermal performance.

DTM

Dynamic Thermal Management evenly distributes excess heat across entire amplifier heatsink.

Heat is often inefficiently dissipated across a heatsink causing "hot spots". This impacts important design goals which are:
