Once again Rockford does its stuff. This amp is a monster and runs my Power 6x9s and 5 1/4" components extremely well. They aren't monster speakers by any means, but this amp keeps them perfectly fed at 75w to the components and 100w to the rears...very, very loud! Keeps the music as loud as and clear my subs keep their bass, which is nice because now I can actually hear the music rather than bass alone.

has the power, quality and runs cool, but it lacks in the mid-low range frequencies.

and to the guy who says he was only using about 15% of amp power u need to learn the gain is not a volume, it is used to tune the amp to the radio outputs, higher voltage = lower settings, lower voltage = higher settings
