Sound quality in aviation is relative. At best, we sould like we're on the phone over the radio. I was worried about the mono/stereo issues. I'm worried if the sould would come out from only one side.
Anyhoo, I'll look into the aux input. Thanks, guys!
BTW, I plan on installing either a Uniden Bearcat 296, or Sporty's Pilot Shop SP-200 or Air Band V.
