XTC 4" Speaker Baffles
from Denver, CO
They seem to work great. They were super easy to install in the factory brackets.
from Maceo, KY
These do what they're supposed to do - contain the sound of my speakers in the door. I admittedly didn't try the speakers first without these baffles, but the cavity inside the door is HUGE. I can only imagine that I'd get some of that hollow, echoing sound we've all heard if I hadn't used these baffles.
