The entire "theory" of the "neutral" is that it, (Shall return the unbalanced load) to the system. And yes it's conductive properties need to be "At least" as functional in resistance as it's positive counterpart.
If it is not? And feel free to try this at home!
Plug in a lamp with just the "hot" wire. The bulb in the lamp will typically explode. Because there wasn't enough of a path to ground and no neutral.
So what happens when you use a lesser cable for your neutral?
Unless your speaker is 100% percent efficient. "AND" can use the entire load, It "can" become distortion if there is too much resistance. Of course this should only happen at higher volumes with most systems.
I hope this helped.
