Fi Q 18 jl 500 give opinion overall

You don't need a better sub - you need a better box first and foremost, and then you need a stronger amp. I say you need a better box because that little pvc port out the back isn't doing shit for that woofer. As far as an amp, maybe a ZX1500.1 or ZX1000.1 if it's Dual 1.

agreed, please do that sub a favor and either build a proper ported box for it, or plug that pvc port and seal it. Either way, you will be doing the sub and yourself a favor //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
