Tempe, Ariz. -
has begun shipping a line of four Prime Class D full-range and mono amplifiers said to be smaller than their predecessors.
Two full-range and two mono amps priced from a suggested $289 to $449 range in output from 400 to 1,200 watts with 2-ohm or 1-ohm stability.
"The technology we've engineered into the new full range and mono Class-D amplifiers allow them to be much smaller and generate less heat," said product development director Jake Braaten.
The two four-channel full-range Prime amps are the $289.99 R400-4D, rated at 400 watts total, and the $399 R600-4D, rated at 600 watts total.
The mono amps are the $349 750-watt R750-1D and $449 1,200-watt R1200-1D.
Their Class D designs deliver high output with reduced current consumption from a car's charging system. They feature onboard variable Punch EQ circuitry, integrated top-mount controls, and optional wired level control.
Rockford Corp. president Bill Jackson said the amps' technology is "not typically seen at this price point" and will encourage consumers to upgrade their factory systems.
