I have a small project to make where I need to provide DC isolation for a
low impedence audio circuit. I need a non-polarized capacitor of about
100 uf. Failing this, what would be the impact of two 220 uf polarized
electrolytic capacitors in series? The latter would be more easily
obtained. This is a one time project so buying parts in bulk is not an
option.

i've seen many used like that with an encapsulated
package to make it look like a single.
btw.
i could be wrong here but if your looking for
100 uf then i think you should keep with using
2 100 uf in series because one is going to short
while the other charges and they need to be back to
back of course.

A clamping diode in parallel with each capacitor wouldn't hurt, just to make
sure reverse charging can't happen!
