But this brings me to my next concern which is how will they fit if the grill is incorporated into their design. Typically it's not an issue except our cycle mount is a little unique to most other mounts, seeing as how it's behind a structure.

And if I'm placing a larger speaker into the fairing opening what's going to happen with an attached speaker grill? Is it going to work, or not... UGH!

I like the specs on those Polks. I was impressed with the 4" Polk speakers on my Tour Glide.
