The only problem I have is that I still
haven't gotten around to marking the cable ends, so that I end up
connecting it the wrong way often, which decreases the volume even
more.

I purposely placed the box at one end, leaving perhaps seven inches of
cable protruding. The shorter side plugs into the audio jack of the audio
panel, which conveniently allows the box to rest inside my Bonanza's
mini-glove box (inside which, the previous owner had the GMA340 external
audio jack installed).

Had the audio jack been on the outside of the panel somewhere, I would have
probably placed the box in the center of the cable and color-coded each
side using tape around the cable to indicate which is which.
