Josh Koscheck’s split with American Kickboxing Academy was not amiable. Starting Wednesday night, we’ll find out the whole situation.

The UFC welterweight star has a falling out with AKA founder and trainer Javier Mendez that plays out in front of cameras for the new reality show “Fight Factory.” The series premieres Wednesday night at 10 p.m. on nuvoTV with a two-hour special.

Koscheck, one of the most outspoken fighters in the UFC, pulls no verbal punches when it comes to Mendez, telling The Post this week that “knowing that I can go to the gym and not see the guy that is a piece of dogs***, that makes me happy.” Koscheck has since started his own facility called Dethrone Base Camp.

Below is an exclusive photo from “Fight Factory,” a show Koscheck says “has the potential to be bigger than ‘The Ultimate Fighter.’” Koscheck flips Mendez the bird during a dispute, captured on camera.
