Speaker Spacer,5 Inch ABS Ring Spacer Speaker Grill Subwoofer Spacer Adapter for Auto Car, 13mm Depth,Pack of 2

Deleted the rear piller speakers in my 97 c1500 beacuse I didn't want to break any of the old trim replacing the stock speakers used these with small qbomb boxes and scar audio 6.5 speakers to set next to the sub box on the back seats worked well

Purchased for use on Harley...outer ring full of visible defects and flashing from manufacturing process...not for use where they can be seen!

They are solid enough, fit the speakers well, and were a decent price

The rings are stiff - I would have preferred some flexibility in the rings to insure a good seal.One ring was smushed a bit flat. I thought about ordering a replacement, but it worked well enough and will not be seen, so I just used it.

I mounted two speakers under the dash of a 71 VW bus which had tweeters protruding past the speaker frame, These spacers worked great to give me the clearance I needed to mount them flush under the dash grill without the tweeters touching the dash.

Perfect fit for my Rockford Fosgate P152 5-1/4 speakers, the screw holes even line up!O.D is just right for the grilles, looks like they were custom made for me!

These are universal spacers but the screw holes don't line up with my speakers. I bought Rockville model RMSTS65 6.5" speakers. The screw holes on my speakers are 1/4" wider than the spacer holes. Maybe Rockville does not use a common standard, or maybe the spacer is not. The spacer fits perfectly on the speaker cage. They are well made spacers and they are sturdy not flimsy and thin. Plenty of plastic thickness for strength. It appears that there was no consideration for differences in manufacturer specifications. There needs to be more plastic to thicken the surface where it mates to the speaker cage and be a bit larger in diameter. If so, I could have drilled my own speaker holes. Because it was not wide enough, there was not enough space to drill custom holes for my application. In 3 of my pictures I used the foam speaker seal as a reference for you to see that the holes lined up with the speaker. The last one shows the spacer and how the holes don't line up. Spacer screw holes are 6 1/4" center to center. The Rockville speaker has holes 6 1/2" center to center.

Had to use the dremmel a little on the inner lip to fit kickers, but otherwise fit and look good

Fits well. Holes line up. Measured with caliper and dimensions are right.
