You might be better off using another deadening product depending on the dimensions of your speakers and the location to be installed. They were not very useful in my smaller truck pillar openings.
They work fine for what they are, but the instructions don't give any indication on where to punch the hole for the wiring. I exercised common sense and poked it through the bottom, but they should really point that out (or mention that you need to make a hole in the first place).

They work really well
require trimming as expected

Trimmed to fit cut small slot at curve, cut slit access for speaker. Leads. Fit was tight on forward speakers as stock grills we're tight but managable.
