Trouble understanding audio amplifier schematic
I have been looking at audio amplifier circuits online to use in a small-ish speaker system I am working on. I found the circuit in the image which is a pretty straight forward circuit and has cheap/easy to find parts. My only question is where exactly do I hook the audio input. I am guessing I connect to the .1uf capacitor on the left chip and to the ground, but I don't know. Thanks for your time.
the circuit is also here:

Your guess is correct :D Between the left hand side of the capacitor (the circle, as lemonie said) and ground.
