[sdiy] Stereo to Mono Amp Question?

[Jay Schwichtenberg]

If it is a decent amp then take the mono input to both inputs on the stereo
amp. Worst case it will cut the input impedence in half (probably 10K to
100K per channel down to 5K to 50K). Most op-amp outputs can handle a 5K
load without problems. Below 5K-3K the drive current and distortion start to
go up on most of the op-amps we use.

Silly people usually don't ask questions to learn things :^)
