INTRODUCTION TO 250 SERIES

INTRODUCTION TO 250 SERIES

The “250 Series” Power amplifiers represent the best Rockford Fosgate has to offer! Our engineers devised technical features which would be considered overkill by other audio manufacturers, but not at Rockford Fosgate! Trans•nova, DIABLO and TOPAZ, exclusively designed by Rockford, are just a few of these features which are described in the Technical Design Features section of this manual.

The 250.2 is a two-channel amplifier which is optimized to drive 2Ω stereo and 4Ω bridged loads. The 250.1 is a single channel amplifier optimized to drive a 2Ω (single amp) or a 4Ω bridged load (pair of amps bridged to a single load).

The “250 series” use Rockford's innovative technologies for awesome sound quality, reliable performance and high output power into low impedances. This can be beneficial for serious competition vehicles.
