It is no exaggeration to say that my history began with my encounter with KICKER, and this new KSS6704 can be installed in most cars without any modification as it can be installed in a wide variety of models. At last year's Alpha Meeting, we dominated 1st and 2nd place in 3 classes with built-in amplifiers. This is a speaker that not only has a sharp and powerful mid-low range, but also has various expressions depending on the adjustment.
