I have door holes so what do I do to clean and sound goooooood?

[Longhorn 70]

Hi guys. I have a 70 that I have owned for 30 years or so. When I bought it, there were 5¼" speakers in the bottoms of each door. Later dummy me cut them just a bit more to install 6" speakers in the holes.

Now I want to make the truck look close to stock. So here are a few questions if I may.

Are there any good sounding speakers for the 6" holes? What is the best way to install to keep them clean and undamaged from the elements? What is the best way to dampen them?

I have considered making fiberglass kick panel enclosures for 4" and adding tweets I have as well. If I do this I'll place 8" under the seat kina like a mid base. Any suggestions there?

I typically only listen to talk radio but once in a while I turn on the blues.

Thanks in advance for any help.
