Kicker subs always have been and probably always will be nothing but teenie-bopper subs that are made for most people to just throw them in any old box and produce bass. They're pretty much just for making lots of noise. They aren't and never have been musical drivers. Most people are attracted to them because of their name. There are many better sub choices out their. JL, RE, ID, Cerwin Vega, JBL all make better subs, just to name the tip of the iceberg.
Quite simply said: Fail.I guess if you just want to make noise, get the Kickers. If you want subs that are actually capable of playing music, look elsewhere.
