I have a friend that owns a audio store been dealing with him for years. I have had a lot of audio installs done by him over the years. He told me that manufactures are making it so hard to upgrade installs to try and having customers removing there factory systems but he said there able to get around things. He said most installs people leave there factory headunit in and just upgrade every thing else. Also another popular things also is customers are just adding a powered sub to there factory system and sounds really good. I was planning on changing out my19 Z06 Corvette bose system but all he is doing is adding a powered sub and it will sound much better. The way it sounds he said he would not replace the speakers. Just add the sub. I already had the whole inside sound deaden and that made a big difference.
