DanssuperO posted:John Thank-YOU so much for the items I ordered Is the adjustable power module ready to install or do I need to adjust it..?
Looks like I might be able to put two speakers in it with this set up ..
You will have to power it and adjust the voltage to the required 5V.
I wouldn't try to use the inputs in parallel, I believe that will be a problem based on the page below. Just use one side of the amplifier. If you want to try two of them, keep the speaker wiring separate and also use a 10uf non-polarized cap in series with each of the amplifier inputs to electrically isolate the DC.
Below are some usage notes on the chip used on this amplifier. You will want a resistor across the original amplifier output in place of the speaker to provide the load for the original amp. I'd go with something like 16 ohms. Also, start with the volume turned low, since you're amplifying a pretty good size signal, you don't want to overdrive the amplifier chip on this board. I suspect it'll only take a little volume increase to go full bore.
