I have a MTX Amplified ThunderForm Custom-fit powered subwoofer — fits 2009-up Ford F-150 I am selling. Looking to get $350 for it. I removed it from my F150 I recently sold. Unfortunately, I left the wiring harness in the truck, so it is not included.

Here is the description for it....

It was only in the truck for 3 months, so it is practically brand new. I paid $550 for it!
