Quoted from BigalzPinz:Hi All !! Just finished installing the Pin Woofer Super Kit System In my Metallica pro and it is unbelievable ! Honestly there is nothing that compares to this system as far as clarity of sound and Bass. Iv'e tried other systems and Pin Woofer is the way to go. For a music Pin like Metallica thats suppose to be played loud... thats exactly what the Pin Woofer Super Kit has to offer ! Dan is always available and willing to answer any questions you may have.... Pin Woofer Rocks !![quoted image]
