i just tried it with LM386 wired using the diagram i drew. it works but the sound quality is horrible. It has more bass than parallel speaker connection though. i just wired it back in parallel.

a coupling capacitor is to block dc voltages going to the speaker. it would go in between the lm386 and the speaker just like in the diagram or between the speaker and ground if you really wanted to(not the best choice).
psp tilt board:
design - 90%
code   - 5% (found my code I was looking for)
testing to come soon
The idea is PvP's, I designed it with AdamThole's version as a guideline

Stereo (just put a speaker where the Leds are)





Mono (just put a speaker where the Leds are)

so the 5v and ground goes to the speaker output on the mobo instead, correct? isn't where you put the speakers the input to the lm386? that would make everything go backwards. it still amplifies?
