No sh1t, ok sq guy get this, My sisters ex boyfriend have 2 visonik 15's and one of their 2400 watt amps, and back then I also had my first system, which just so happened to be 2 12" pioneer (i was young) and an american legacy(once again i was young)1200 watt amp and mine kicked the sh1t out of his. visonik is a joke i honestly dont even think wal-mart would/should distribute them.And just to piss you off more, one of my channels went out in that ameican legacy amp, so i am running those off 1 channel.They were also in a bandpass box purchased at a discount store for 69.95 that box is junk, yea visonik is the best out there though.
