Chapter 13 of the SCCA Solo rule book allows for accessories, gauges, indicators, lights and other appearance, comfort and convenience modifications which have no effect on performance and/or handling and do not materially reduce the weight of the car.
Does this mean the factory stereo can be removed and an aftermarket stereo installed provided it and the associated components (amplifiers, speakers, head unit, etc) are similar in weight to the factory components?
As long as "similar" means "not lighter" then yes. But realistically nobody is going to ask to weigh your radio unless it's obvious you did something with the specific intent to reduce weight.
I believe the first time radio deletes are specifically mentioned as legal is Street Prepared. That being said, I can't imagine anyone protesting you unless it's obviously part of a large weight loss program.
[edit] Please ignore my reading comprehension fail.
I ran aftermarket radios in almost all of my STS cars. You're fine.
Stereo stuff is fairly open, even for Street classes, providing you're swapping items of similar size and function. You can even "downgrade" using aftermarket parts. For example, if you have a car with a heavy factory subwoofer and amp, you can replace it with lighter aftermarket equipment, so long as you're emulating a factory setup that was also available in your specific model.

And the "amplifier" doesn't require a cooling fan that coincidentally happens to create a partial vacuum under the car. :)
