I listen to a lot of talk radio when I drive. It is very frustrating when one talker seems to whisper and one to almost shout The radio stations seem to do nothing about this. In fact my favourite show has a presenter who seems to whisper, so that when talk switches from him to someone else, I have to keep jiggling the volume control, which is both annoying and potentially dangerous.
[Update] Hoping to avoid any more downvotes. I came here to ask what hardware to buy, not how to install it.
If someone can recommend a car radio that does what I ask, then I can contact the manufacturer & ask if it is compatible.
There surely can't be that much difference between them, can there? If it is so important, then it should fit a 1991 Mazda MX5 Miata
