This sub has a pretty good kick to it. The sub seems to favor the low end of the audio. Sometimes, you can feel the kick from the sub (mounted behind my seat) more than you can actually hear it. After making adjustments with it's settings I was able to get desirable sound after turning up the low pass filter all the way. The volume control is very handy when you don't want to hear lots of bass when listening to talk radio.
UPDATE: After 25 months of regular use, I am pleased to say that I have not had any issues with this product. The sub and it's control control knob work the same as they did when I first installed it.
