Hmmm, more wires to run, more stuff to put in the plane.

More wires under back seat; fewer under panel. If most
antennas are on the belly...

The equipment didn't go under the rear seat; it went behind the panel
behind the bagage compartment.

Either way...the back seat comes to mind because you could pull the
seat and SEE what you are working on.

The diameter (up to a point) of a cable bundle isn't an issue; it's
having to run it at all.

But lots of wires is connectors with a bunch of pins to solder, and
when the unit does not work, you end up with a DVM and sharp probes
to test each pin to pin etc. {I used to hate that kind of work..}
And fiber weighs less.

Instead we install oh 5 pairs of fiber with ST connectors. Use one
pair for nav/com, another for GPS, etc. Suspect trouble? Swap both
ends w/ another pair.

Fiber all avoids ground loops as well. I could see a audio panel
with a front panel for control, a knee-level jack panel for
mikes/headphones/PTT/CD player in, and a 2nd in the rear for those
passengers.

You didn't have ground loops back then with wires either if you put
stuff in correctly.

Until this ground or that came loose, or....

I'd buy connectorized flexible duplex jumpers. But yes, you'd need to
run power there. Good place for the avionics master contactor.

Hmmm, 3 more wires; power in, power out, and control or have 2 separate
contactors for the front and rear stuff and avoid the power out?

Avionics master switch goes two places -- to run panel remotes;
and contactor at rear rack.
