How do you parent an audio component to a static mesh component that's being generated on the fly?

I’m spawning 300+ static meshes (of cars) along a spline loop and moving them along the spline. The static meshes are spawned whenever the spline changes. I’d like each of the static meshes to play a sound.

How do I achieve this? Thanks!

I would like to possibly do this without having to move both the static mesh and the audio (so that the audio always comes from the static mesh).
