I'm selling a OEM subwoofer and amplifier assembly that came out of my new 2013 FX4. I prefer the space, so I removed it as soon as I got the truck home. It's unused and in perfect condition. I've also got an OEM rear rubber floormat that's shaped for the sub, might be willing to trade for a non-sub-cutout version if your's is in good shape.
Asking $125. Louisville, KY pick up or buyer ships.
Can't find a pen in to save my life, so please excuse my digital piece of paper
