When I was growing up and reading car stereo review, and Auto Sound & Security, Waveguides were coming on. Saw a set, made by USD, at a joint, & almost snagged em just because. Anyway, I left, and posted this after I looked around the Acura to see if I could use em. I don't see them anymore, and was wondering what the mass opinion was out there???.. As always, thanks for any and all help.
