CEA-2006
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.
Class bd
Rockford Fosgate bd topology is a revolutionary patented design, 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? More power from your amplifier with less drain on your vehicles electrical and charging system.
Differential Inputs
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.
DSM
DSM utilize 1% tight-tolerances improving efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature.
Dynamic Thermal Management
Heat is often inefficiently dissipated across a heatsink causing "hot spots". 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.
MEHSA3
MEHSA3 (Maximum Efficiency Heat Sink Application--gen. 3) reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span.
NOMAD
NOMAD (Non Multiplying Advanced Decision) is a "real time" analog computer that protects your amplifier from shorting speaker wires and dangerously low speaker impedances.
Punch EQ2
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, and 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 are boosted.

TO-247 MOSFETs
Rockford Fosgate amps use custom TO-247 MOSFETs. These have 60% more metal tab area for more power capacity, lower impedance and improved heat dissipation over traditional TO-220 MOSFETs found in competitor amps.
