Ford F150 Kicker SF150C09 VSS Subwoofer

I've had this installed in my truck for the last year and it works beautifully. I am the original owner. It completely blows away the stock Sony 8" subwoofer that came as part of my Sony premium stereo system. It's also super easy to install if you have the Sony subwoofer. The wire harness is plug and play with the existing wires. Brand new it's over $650. I'm asking $350. 09-14 FORD F-150 SUPER CREW KICKER SUBSTAGE POWERED SUBWOOFER UPGRADE KIT  Extra Info: KICKER SubStage Powered Subwoofer Upgrade Kit for 2009-2014 Ford F-150 Super Crew. Powered subwoofer is not compatible with 2009-2010 trucks that have Sony factory premium audio systems, but is compatible with 2011-2014 trucks with Sony factory premium audio systems   The SubStage doesn't skimp on power and performance — it comes equipped with a 10" sub powered by a perfectly matched 200-watt amp, all housed in a custom enclosure that's optimized for sound quality. You'll look forward to rumbling lows that can play back the biggest digital drum beat yet also deliver the low-frequency subtleties of a standup bass. Kicker's earned their reputation for making subs that crank out bass you can feel and the SubStage is no exception.   The SubStage SF150C09 fits the 2009-12 Ford F-150 Super Crew Cab, and the subwoofer installs under the passenger's side of the rear seat. This kit will not install in 2009-10 models with the Sony factory audio system. It connects to the factory stereo via two wire taps for signal, and attaches to the battery for power.
