Standard cut out size for 5.25" speakers?
 

I am cutting some mdf rings for some fiberglass speaker pods I want to make tonight, but I only have an old school set of MB Quard 5.25s to base it off of. MB Quart hardly uses standard sizes at the best of times.

I need to know what would be some good standard measurements for both the inner and outer diameter of modern 5.25 speakers cutouts/rings, not including grills.

please and thank you

Can you measure the parameters?

I am unsure what you mean.

these are going on the fairing of a motorcycle. I haven't picked out a final pair of speakers to use because I want to use my old-school speakers for a while, and only switch them out if they crap out or dont meet my expectations.

I just need some good, universal dimensions to use for cutting out the mdf rings, so i have the most options to drop 5.25 speakers in, in the future.

I chose 5.25 because it is pretty common and not so huge as a 6.5 to look awful on the bike.

5.25" speakers always have the same mounting holes. I wouldn't worry.

We carry JL Audio. I looked up the speaker's mounting specifications for you here:

TR525-CXi - Car Audio - Evolution® - TR - Coaxial Systems - JL Audio

As you can see, the mounting diameter is 4.56". That's pretty standard nowadays as Installerz had said earlier.
