Thanks, I'll give this a shot and see how it goes.

Your problem is that you are using a "box" for the junction. Four things
bad. Three of them are where the wires enter the box you have a singular
strain point and a chafe point. Grommets will only go so far to relieve
either of them. THe fourth is the weight of the box itself snapping the
wires about in turbulence and such.

Join-solder the wires to the main cable with shrink over them, then shrink
over the both wires, then a large shrink over the whole mess. A large dab
of RTV at the center of the junction before you shrink, then the shrink will
force the RTV into any voids in the junction.

but the tough one is at the junction/strain relief box where
the mic, phone, and main cable join. Any input for a suppliers?
