stay on tpoic, thinking the best bang for the buck and it isnt even close is vapor sound stiff breeze
Nyaudio98, you started this same thread last year and ended it as Vapor being the best. Looks a little suspicious. Even your previous answers pride Vapor.
Google search turns up nothing on a "Delco 65 recv" (receiver, I assume)?

Hard to say anything meaningful without knowing what will be driving things.

I'm assuming this is not the old GM DElco car audio stuff, right?
