Cutout size: The hole in the car door or rear deck where the speaker mounts.
-
Mounting depth: The space required behind the speaker for proper fit.
-
Grille clearance: Ensures the speaker doesn’t interfere with panels or seats.
All cars do not have sufficient space to fit aftermarket speakers hence these measurements will save one inconvenience during installation.
How to Measure Car Speaker Size?
Learning how to measure the size of the car speakers properly will make sure you get the right replacement speakers and save time in returning and changing the speakers. Here’s a step-by-step approach:

-
Check mounting depth by measuring the space behind the speaker frame to the panel or obstruction.
-
Note screw hole spacing to confirm the speaker can be secured properly.
-
Check clearance for grilles or covers to ensure the speaker won’t touch surrounding parts.
Checking these dimensions twice will not only help you prevent fitment problems, but also make sure that your new 6x9s will slide right in.
