And then you have the issue with running turn downs or all the way out of the back.

Out of the back, I don't think it will matter which ones.

Turn downs will be where the small difference will be noticed. But I recommend if doing turn downs, make sure (and watch) the guy point them to the outside of the truck just a little, so the sound doesn't bounce right back up at the bed floor and resonate in the cab.
