Kick panels with speakers

Wasn't quite sure where to post this since it's not a question. I know there already exists some aftermarket kick panels that house 4x6 speakers, which I always found the decision to use that size rather odd. Well, I just came across a set of panels that accept 4" round speakers that I've never found before and thought I'd share.
