Looking up through the right front grill you can see daylight.If you remove the speaker housings you can see right through the grill... I will take a photo tomorrow during the day.
Looking down through the right side speaker grill... plenty of open space.
Plenty of open space on the left side, too.
It might be difficult to see the amount of space up there with the speaker boxes removed, but there is a lot of space!
Not easy to photograph, but plenty of air flow through the open speaker grill covers...
I hope these photos help illustrate how air can flow through while riding.
