Summary: This thing is awesome!! I have it hooked up to a hifonics brx2000.1d amp and I have a 2.25 cubic ft enclosure (needs a 2.75) but dang!! This sub is wired to 3 ohms and is pushing about 1000watts rms. this thing is definitely underrated!
Summary: By far the best car subwoofer I have ever heard. This thing produces clean and deep bass that hits you without no annoying distortion. I will own this babe for a nice 10+ years. When your looking to buy a subwoofer, you have to ask yourself how good is the bass.

Summary: This sub lives up to every 5 star review. It is a total beast and produces some incredibly detailed bass. I have 2 now - one in a sealed 1 cubic foot box as suggested by JBL for optimal sound accuracy and another in a tank of a ported bassworx box. Both are made of 1" mdf.
Conclusion: wow, what can you say. for starters this sub is rated at 700Watts RMS, but it is quite capable of handling much more! i did contact jbl's tech support and engineering department when i hooked this sub up to my planet audio BB2400.1, i told them that i was sending ~1200 watts to this sub.
Summary: I bought 2 JBL W12GTi MkII, 4 years ago, and still bring a powerfull and deep bass, like never before i heard. this subs, need a big responsable amplifier, i had a Power Acoustik 5500 (peak) 1700 rms 4 ohm. but remember this subs had 6 ohm, so for avoid damage it amplifier have 755% gain level.
