I've had problems with phonecalls being insanely quiet ever since I installed my Helix DSP so I suspect it has something to do with routing. I don't recall if the phonecall audio was only sent to the rear speakers during the OEM setup, but it's what happens now. I do have my phonecall volume maxed out on my Honda head unit (30) whereas I can put my music volume to like 16 and listen comfortably.
Is there like an additional audio routing that needs to be done to send phonecalls to the front speakers as well? My bluetooth phone call audio is pretty much unusable at this point.
