I have no expierience with this particular sub but I can tell you that Clarion Pro Audio is decent stuff. How much are you paying for it? what kind of car is it going in? and what kind of amp are you going to be running it with? also are you into SQ,SPL, or SQL?
Im payin $250 Australian for the sub and im running off a 1000watt rms clarion mono digital amplifier. I havent heard of SQ, SPL and SQL what are they and ill check them out.
