INTRODUCTION TO 50 SERIES

INTRODUCTION TO 50 SERIES

Rockford Fosgate is distinguished as the global leader in building high performance amplifiers. Since the introduction of the 250m2 and 250m, new performance standards were set for sound quality and flexibility and have risen to an even higher level with the introduction of the 50.2 and 50.1 “competition” amplifiers. The “50 series” utilize similar technologies of their predecessors like trans•nova, TOPAZ and DIAMOND; however, they have enhanced power supplies for driving very low impedances.

The 50.2 is a two-channel amplifier which is optimized to drive 1Ω stereo and 2Ω bridged loads. The 50.1 is a single channel amplifier optimized to drive a 1Ω (single amp) or a 2Ω bridged load (pair of amps bridged to a single load).

The “50 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.

PUNCH AMPLIFIER ACCESSORY PACK

The accessory pack shipped with the “50 series” Power amplifiers include the mounting hardware necessary to secure the amplifier to the vehicle and to attach the end caps to the amplifier.
