used to make mount for replacing speakers
Crutchfield Customer Review (What's this?)
Crutchfield has great tech support! when we ordered replacement 4" speakers for our in-dash factory speakers in 1991 Toyota, we found with the help of tech support that we needed to create a mount for the speakers as ours was missing and the speaker screw holes didn't match up with the factory screw holes. This was the solution we needed and Crutchfield sent at no charge to ensure we could install our speakers!
Pros: worked to create speaker mount for in-dash replacement
Cons: a little hard to work with cutting it
