PAM8302A not working with Pi Zero and a low pass filter

[Avendor]

I have it wired and the low pass filter working. I can hear sound from my earbuds and speaker, but it is very low. Turning the pot on the PAM8302A doesn't seem to be doing anything and just turns forever in either direction. I'm almost positive I have everything wired correctly, but maybe I don't? Everything is connected to a common ground that is then connected to a ground pin on the Pi.

I am testing with Raspbian right now with the volume at max with alsamixer. I just can't get any volume from the amp. Whenever I touch the PCB I do get a lot of static which can be loud, or soft depending on where I touch.

The ground wires are all grey with orange and blue being the sound signal. I followed this guide to make a mono low pass filter to my mono jack.

Any ideas?

Small update, I remembered that my roommate has a Creative SoundBlaster USB audio adatper that I just tested works with a Pi 3 running Raspbian. That way I will get clean stereo rather than the questionable mono I was going to get the DIY way. I now just need to figure out how to wire the mono speaker with the switch in the SB jack.
