I literally just posted this on another thread.

I have installed a Custom Autosound Bluetooth car radio that looks retro with old push buttons and says VOLVO. I just looked - and it is 300W. I never turn it up that much at all. I am very happy using bluetooth with it - but do not expect an easy to figure out system. It is kinda screwy if you use FM, etc a lot. Basically, I get in the car and it connects to Pandora on my phone. The left knob is volume, the right knob skips to the next song. I really am not sure how to use fm, etc. Bluetooth is all that I wanted. I cannot say the sound is awesome, but all I have is a few good speakers in a box under the rear window. I have hands free phone too! It works really well.

I see nothing wrong with this - and it is not likely to be stolen. You have to enjoy your car. Music sets the mood.

Welcome to this Forum!

Leaving the OE radio in place will certainly look more "period"...but as "Breaker" notes, there are some modern radios available now with modern features, but in a period look...note also there is also only limited room in the stock location (some of the larger [probably before '69, Ref: https://www.sw-em.com/Radio_Notes.htm#The_1800_Radio_Wedge] older radios required the "radio wedge" to clear Wiper linkage in the back of the radio hole), so IF you are considering changing the unit, measure available volume for the new unit after removing the old one...

Another completely different solution which I like is to leave the old unit in place for appearance, and add a modern unit discretely (under dash or seat)...some of these units are remote controlled, and have RF/BlueTooth connections to your mobile device, so their discrete location would not pose a problem...and like I always say: No see 'em, no steal 'em!

Breaker; Try adding some small tweeters in the front, facing occupants as well as possible, to improve channel separation and stereo imaging.
