1.How to Select the Right Car Speaker Spacers
Check the vehicle owner's manual: The speaker size is sometimes listed in the audio system or specifications section.
Online Lookup: Visit well-known North American car audio accessory websites, enter your vehicle details - year, make, model, trim level. The site will precisely list your factory speaker dimensions and recommend perfectly matching speakers and installation accessories.
Manual measurement: Remove the door panel and directly measure the diameter of the factory speaker ID and the mounting hole spacing.
A: If the measurement is 128mm-5.04inches, you will almost certainly need spacer with a 146mm-5.75inches inner diameter.
B: If the measurement is 131mm-5.16inches, you will need spacer with a 149mm-5.87inches inner diameter.
