Two New Class D and Two New Class A/B Amps Designed for High Power with a Small Footprint for Installs that Require Big Output From Little Space

Rockford Fosgate announced four new affordable Prime Series car amplifiers, which include R250-1D and R500-1D mono block amps and the new R125-2 2-channel and R250-4 4-channel Class A/B amplifiers.

“We’re pleased to be able to offer better efficiency in our Prime mono-block amps through the implementation of Class-D circuitry,” explained Theresa Hephner, Rockford senior director, products and marketing. “The new R250-1D and R500-1D mono block amps provide the same high power as their predecessors with greater thermal longevity, built into a smaller chassis that will fit wherever the customer desires.”

Also new for 2012 are the R125-2 2-channel and R250-4 4-channel Class A/B amplifiers. “Based upon Prime’s affordable yet reliable reputation, the R125-2 and R500-4 take the multi-channel, small footprint amplifier to a new level,” Hephner continued. “These full range amps are perfect for those installs with little room to spare, such as under a seat.”
