This is a dumb question I'm sure.

I've searched here and on the web and still haven't found an answer. Even looked at the Mazda install pics.

I'm happy to have a big box here in front of me from a Mr Don. I've seen pics of the cod tiles installed on the outer door skin and other pics of it on the inner. By inner I am refering to where the door panel mounts.

Which is correct? My goal is to block road noise and help improve the sound quality of my mids.

I do have MLV to mount on as well. And I didi figure out where that goes lol.

Thanks!

Which is correct?

Both. You want to apply the CLD to both the outer & inner door skins/panels. Typically Don recommends 5-6 CLD tiles on the outer door skin (half of those on the top portion of the outer door panel above the brace and the other half on the bottom portion of the outer door skin below the brace). Then typically another 1-3 CLD tiles on the inner door panel (based on how much surface area there is, etc) applied to the most resonant areas of the panel.

The purpose of the CLD isn't to block noise, it's to reduce resonance & vibrations. The MLV is to reduce road noise.

Thanks! Yes that's why I got the MLV to go with it

I know it is supposed to work as a system and wanted to be sure I installed it correctly.

Where do i get these CDL tiles
