Like the response above, avoid Jeep because almost all of their vehicles are unreliable. You can afford a slightly used 4Runner. It will be the most reliable SUV you'll find along with the Toyota Highlander. The Highlander is not meant for off-roading, but is much more comfortable than the 4Runner and more spacious.
As far as premium audio systems go, I have experience with JBL and Bose. The Toyota JBL systems are better than the Bose systems found on Mazda and some GMs. They are both good, but the clarity on the JBL is instantly noticeable. The JBL has just enough bass, but the Bose almost has too much bass even though I like more bass. The Bose is less crisp. Honda doesn't have an audio partner, so they build their own audio systems. The Acura ELS systems are known for being some of the best in the business.
I'll suggest the 2017 and newer Mazda CX-5 as I often do. It is stylish inside and out. It's reliable. It is available with modern features and a nice screen. Today, Mazda announced they will be putting CarPlay into their cars. Older cars may get a retrofit later. The CX-5 handles well and it fits with your priorities. If you value driving dynamics, this is the SUV.
If you need CarPlay, the Honda CR-V has it. It will probably be a little less reliable than the CX-5, but still good. The CR-V will be more comfortable than the Mazda, but more durable and utilitarian for better or worse. It handles pretty well and is smooth. As far as interior tech and safety feature availability, the CR-V beats the CX-5. For most people, the CR-V is the better choice.
New CX-5s and CR-Vs can be had for much cheaper than the Jeep and 4Runner and I think they are the better deals.
You didn't say you needed an SUV or AWD. Best of luck on your search!
