Slims fit perfect
Crutchfield Customer Review (What's this?)
Easy install, i did need to cut a hole for the wiring to pop out so it wouldnt get smushed. I tried my new Polk 572s with and without these during install and these DEFINITELY helped direct the sound into the cab instead of the door! Made a significant difference in volume and base without muffling anything. The slims do NOT affect window function or any other door buttons for all 4 doors of my Explorer... the regular size probably would have rubbed on the window tracks in the front doors, so im glad i got the slims. The 572s have plenty of room to spare depth-wise too.
Pros: Helps sound quality Perfect fit
