i have owned 2 kicker competition 10 inch subwoofers.
2 15" kicker subwoofers. and a few kicker amps. and i must say for the little price i pay compared to the other subwoofers out there. i get the most bang for the buck. im truely a bass head now thanks for kicker. i hav owned visonik before and there pretty decent but nothing special. sony xplods ive owned and got rid of the next day. i dislike them and dont like the weird look of them. ive owned baja subwoofers and there pretty good bang for the buck.
