I have a Kenwood DNX8120 which is a great HU pushing the amp and sub linked below. Am I getting the best outcome with this pair or am I robbing myself of some high quality sound? I love how it hits, deep bass and no distortion, but I always wonder how would a more expensive sub sound or a more expensive setup like Focal's would sound.
