Fabricated (2) Headphone jack mounts. Installed them on the intermediate bulkhead behind the instrument panel. Just above the jack mounts on each side of the cockpit will be speakers. I will clean up the speaker holes and install screens to protect them. Found a couple of small auto speakers, 2x3" 40w... Tested fine. Of course I will be using headphones during flight... just a backup source of audio. It is also nice to listen to ATIS/AWOS during the preflight.
