75 Granville speaker replacement

What size speakers are in the grandville convertible dash and how to remove it

From what I see B bodies used 4x10 speakers.
Recommend you refer to the factory Service Manual for detailed instructions but assume if you have AC ducts under dash they have to be dropped to gain access.

That lil dash speaker is garbage. No replacement speaker is gonna give off the sound you want when cranking your tunes. I'd suggest looking into have console built so you can run some 6.5s. That's what I'm doing so I can run more speakers without jeopardizing the original interior. If you wanna just stay with the dash speakers I'd suggest adding some bass blockers to them to avoid distortion.

Check with Crutchfield they have a lot of speakers for vintage cars.
