Center Speaker as a “sound bar” or mono audio with a simple amp

ok I know y’all are not going to like this.. but I’m really just trying to make due with what I have and I’m tired of hearing my tv’s absolute trash audio. Could someone please help me in connecting an old center speaker to a Dual Channel amp? amp has 4 outputs- L (red/black) and R (red/black) Center speaker obviously has 2 inputs red/black. I’d be fine listening to mono as well I just can’t figure it out Thankyou
