i dont know about the one you mentioned above, but ive just fitted a pioneer tsw11a underseat sub under the passager, with my upgraded pioneer speakers alround, im pretty chuffed with the outcome, more bass then id thought id get, but not like a proper sub, the bass is linear with the volume rather than bump bump bump at low volume, cost me £160 for the sub and comes with remote and wiring harness, and if youve got no rcas then theres a speaker-rca adapter that comes with it. also as well the brackets that screw to each side of the underseat sub, more or less line up with the seat rails brackets (brackets for option cabasse) with a bit of hole lengthing outwards (sub brackets) and drill out hole bigger to fit pins on the seat brackets it looks likes it was ment for the car.
