Hi,
normally the inpedance modification only concerns the audio part of it..
suggest you check the "david clarck" web site..where you should find a lot of modification kit..
anyhow, a deep verification should be done by an avionic's technician to be sure about this on the plane and installation on which this is intended to be used..
Don't play with this kind of stuff..
