Audiotech Fischer Car Sub Setup

Selling my Audiotech Fischer 10 inch down-firing sub and UP1FX amp. Comes with a knob that you can run to the front of your car to change the bass, and a fuse. I had it installed for about 4 months before I decided to change vehicles. The new car has a sub already, so I don't need this one. It sounded great with heavy-hitting, high-quality bass. If you have any questions, I'll do my best to answer them.
