Rockford Fosgate T600-4

The Rockford Fosgate T600-4 is a 4 channel amplifier designed to cover front and rear car audio outputs. While similar to the Rockford Fosgate T400-4, the power output has been increased to a total of 600 Watts.

It can be used to have front midrange outputs and surround rear speakers, and a built-in crossover allows the rear channels to work with one or two separate subwoofers. The front and rear channels have independent high-pass and low-pass controls for fine tuning of the audio, and general tone controls are also available to get the right mix of Treble and Bass. The compact design allows installation of this unit under a car seat.
