    Works Like it should
    I am running this amp on my Rockford Fosgate Punch P1675-S component system in the front and Rockford R165X3 in the back and the sound is amazing. I am not running the gain wide open and I am still getting 116dB in the car with the Kenwood KMM-X503 stereo volume on 30 of the max of 40. (Sub is MTX RT8)
