I remember my Dad buying a very base-model car - I think it might
have been in the '80s, or possibly even the '70s - and fitting a
radio to it for him; I was surprised to find it not only had the
wiring, but actually had the speakers! (In the doors, anyway, which
IIRR was adequate for his wants. I'm pretty sure it was a Peugeot.)

In general, it's cheaper to build a standard base model prepped for all
add-ons than to build cars with different preps for different add-ons.
this is true for pretty well manufactured objects. Different models of
fridge will have the same handles, shelving, drawers, etc. And plugged
holes where the ice-maker or ice-water dispenser is attached in the
higher end ones.

Bits and pieces are often much cheaper than inventory control and
assembly costs.

I wouldn't have been that surprised to find all the wiring present, but
finding the actual speakers there, rather than as you say plugged holes
(or, more likely, just the push-on wires left hanging) did surprise me.
