Perfect

February 27, 2012

These worked perfect on my 96 single cab silverado. I put one 5-1/4 speaker on each door panel using these spacers and they worked perfect and the speakers sound great. I Would Recommend this to everybody.

A must-have to add depth

October 11, 2007

If you don't have much depth area for your door speakers, then get these spacers to add depth. So easy to use.

OK but disappointing.

March 27, 2012

Not what I was expecting based on the illustration. Spacer is actually just thin walled plastic. I was able to mount speakers in my Mazdaspeed 3 but it took a lot of trimming plus drilling. Did not reinforce the plastic door inner panel like a solid spacer would.

Great Spacers!

July 28, 2013

I had a pair of 5.25" speakers that were too big for some pre-fabbed enclosures (holes were too small) that I bought from an online retailer to mount. I mounted these spacers and "Wah-Lah" they saved the day!
