89 C4 Bose Radio and at least one amp dead
 

My 89 is in great shape with 40k miles, it is really worth it to repair the stiock cassette radio and amps to keep it original? I am new to Corvettes but there seems to be an affinity to keep them all original. I do not have any cassettes, so I would stuck with just radio, so why keep it original?

If you are happy with the sound of the bose, fix it. I've never seen a radio aside from the Camaro CD units that I liked for replacement.
You can always install an auxiliary for an outside music source such as ipod or phone

For me, it is a matter of keeping the dash looking stock on my 89. I use this from Amazon to add bluetooth support for music streaming and making phone calls.

This was not as much work as you might think and it sounds like a different system. Not the typical Bose "meh" sound, good clarity, and some real bass.
