Whats wrong with my setup?

I got a pretty basic set up of an electric guitar and an amp I got almost 7-8 years ago but barely started using it. The problem I have is I think my amp, it’s just way too quiet. I’ll have everything properly plugged but despite having max volume on both the guitar and amp its impossible to hear it or it just doesnt get picked up at all. Anyone got an idea whats wrong with it?
