Loud as hell
This is not the first time om buying a Rockford Fosgate amp to my car.
Its 4×50 watt but it plays more than it should and with Good quality on the sound.
Im using it in 3 channel mode. Kit in front and a 12 inch subwoofer.
And this amp plays really good.
Thumbs up again RF.
It sounds like a trance festival in my car.
