One side to the 8V audio output, one side to the signal ground, and the
wiper to the low voltage amp input. Use a pot in the area of 1K to 4K.

The 200K series-only pot idea doesn't work because the impedance will
become too high. The impedance to the amp should be no higher than a
few K Ohms to avoid loss of trebble, electrical noise pickup, and
distortion due to non-linearities of the amp input's impedance.

I'll try the pot.

How do I wire it? Like this:

Or do I want the wiper to sweep to ground?

200K is way too high. The impedance will be too high to overcome cable
capacitance and electric noise. 1K would be more like it.

No, 1kohm would be worthless. It would provide somewhere on the order of
0.2dB attenuation, which would be inaudible.

I suggested 200k ohm as a POT value, so that he has sufficient range to make
the determination. I suspect the resistance value that will provide the
results he's after won't exceed ~50kohm.
