I have a 27v2 but I have yet to hear it in my car

Car starter season means my fibreglass probably won't get done until February or March.
I have, however, heard it in other cars and quite like it.
I have not heard the one you're looking at, but I have seen it. I could not fathom why you would need an 18" sub in a car, especially for SQ. I use two 18" self powered Yorkville subs at 1500W each to DJ dances with 700 people in a warehouse and it's STILL freaking loud!
