Got ahead of myself with board building so I figured I'd throw a freebie, there were a few others like you who got an upgrade

I am a tad confused with this.

The PAM8403 has a R+ R- L+ and L- output.

You have connected the + up to the solder pads and then only one of the -. The other seems to go to a small solder pad and then stop.

Why is this?

One of the Negatives was enough to have stereo sound during my testing when I was designing the board and I left that tiny pad off to the side in case it would be needed in the future. I have a new design being tested this up coming week that uses both negatives and positives and eliminates all the confusion people have with wiring the sockets and speakers.

Ah ok, how are you wiring t u to use both negatives?

It seems connecting them together is a bad idea!

Using resistors that tie into the Speaker Negative terminal, there are many diagrams and discussions on this subject online and seeing as the speaker isn't really that powerful it shouldn't be much of an issue and this is why I will do testing to see what values work best.

Ahh OK great!

Thanks for the info. I have been trying to find it online because I have one of the PAM 32 amp boards and I am.trying to figure out how to wire it!
