Rockford Fosgate P500-1bd Punch® 500 Watt Class-bd Mono Amplifier(RKFP500-1BD) and other affordable Crossovers at 6ave.com.

With its super efficient Class-BD circuit topology, the P500-1bd will drop some serious BASS! Due to its dedicated low frequency response, this amplifier is optimized for mid-bass speakers or subwoofers only. No need to worry because its 1-ohm capability will drive a pair of 4-ohm DVC subwoofers or quad-configuration of 2-ohm DVC subwoofers with ease.

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.

DSM
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.

NOMAD (Non Multiplying Advanced Decision)
The NOMAD circuit accomplishes just that. It's a totally new and very high tech method of dealing with device current and voltage parameters, without being affected by other factors such as heat. Our approach to "real time" protection is one that uses a mathematical transformation which eliminates the problems encountered with trying to do real time multiplication of instantaneous device voltage and current. Essentially an analog computer calculates at each instant, the maximum allowable level of safe current for each output device, based on their instantaneous voltage drop. This allows the protection to be much more precise than ever before, and ensures reliability.

TO-247 MOSFETs
The MOSFET transistor is the best type of device to use when building a high quality mobile amplifier. The Power family departs from the traditional use of the TO-220 package MOSFET semiconductor found in most competitive brands in favor of the substantially larger TO-247 package. The TO-247 has 60% more metal tab area and its unique, fully encapsulated design is capable of housing a silicon die (the heart of the MOSFET) twice as large as the TO-220. The larger die provides more power handling capacity. Additionally, the extra metal tab area ensures that no matter what size silicon die is inside, the thermal impedance will always be lower than in the TO-220 due to improved heat dissipation.
