By David D. – Product Specialist
Rockford Fosgate has produced the high quality Prime Series amplifiers for the “novice” car audio enthusiast. The Prime Series amplifiers feature the reliability and power you are used to getting from Rockford Fosgate while fitting into your budget. These amplifiers are available in Monoblock, 2-channel, and 4-channel configurations and are all CEA-2006 complaint, which means that the specifications and power ratings are actually true to performance and not beefed up for selling purposes.
Prime Series Amplifiers Range from 150 watts to 1000 watts and each feature adjustable Punch Bass tone controls. The power and protect visual LED indicators are common amongst all the amps in this series as well. Some other features that each amplifier shares are, the low level signal inputs and outputs, screw terminal barrier strip, extruded aluminum heat sink, convection cooling, and each run off 4 AWG power wire and up to 8AWG speaker wire.
The Monoblock configurations all feature a Low Pass Filter (40-130Hz @ 12 dB) and have 1 pair of low level signal inputs and outputs. These Monoblock Prime Series Amplifiers are available in 2 Class AB circuitries (R250-1 and R500-1) and 1 Class D circuitry. Each includes a Punch Level Gain Control remote with an adjustable bass control (+12 dB @ 45 Hz). Prime Series Monoblock configurations range from 250 watts to 1000 watts of RMS power.
