the sound wont work... now let me explain my wiring(pi to amp)
-I am doing only mono, this is why only one half of the low pass filter
-yellow wire out of low pass filter goes to the potentiometer
-I accidently bought a stereo amp, this is why I bridged the connection that comes out of the potentiometer to L+ and R+
-same goes for R- and L- which are connected to ground
amp out:
L- & R- = headphone ground
L+ =Left in
R+=Right in
Speaker + = Left out
Speaker - = Headphone ground

what am I doing wrong?

Have you added the command into the config file to activate the sound?

yes I have.

That doesn't look like the right PWM pin you're using on the Pi.

PWM audio on the Pi uses pins 13 and 18 by default and as per config change.

See purple and blue as below.
