Ok first off I will start witht the fact the I had about twelve professionals tell me Boss was junk/bottom of the Barrel! I proceeded to buy theses, cuz of the price and i was short on cash, well lets just say these are top of the line for the price, would compete with kicker, rockford, MTX, and JL!!! i have two of these things in my trunk with the 2 channel boss phantom 3000W amp! I am very impressed, they hit extremely hard if tuned right!
