Kevin Amankwaah began his career as a trainee with Bristol City and had been with several clubs before appearing for Exeter City in 2012/13. He later played for Northampton Town.  

After turning professional at Bristol City in January 2000 Kevin later suffered an injury in a car crash and struggled to re-establish himself in the first-team. He went on loan to Torquay United, Cheltenham Town and Yeovil Town before eventually leaving Ashton Gate in 2005 to sign for Yeovil permanently. Kevin was then to move to Swansea City in July 2006 for a fee of £250,000 whereafter, in June 2008, he joined Swindon Town where he played until being released in August 2011.

After splitting himself between Burton Albion and Rochdale in 2011/12, Kevin arrived at Exeter City in July 2012 on a one-year contract. After making his debut in a League Cup tie against Crystal Palace he soon became a fan's favourite and played thirty-four league games before leaving the club in April 2013.  

Kevin then joined Northampton Town on another one-year deal but this was terminated in January 2014. This proved to be the end of Kevin's Football League career and, thereafter, he played for Salisbury City and famously Sutton United for whom he appeared in the run to the FA Cup 5th round in 2016/17. Kevin was to leave Sutton at the end of that season and joined Bath City at the start of 2017/18 before moving, after two seasons, to Salisbury for a final season ahead of retiring at the outset of COVID-19.

Kevin has since worked as a fitness trainer in Bristol.
