I've been saying it for 30 years so I might as well say it again ... "BOSE SUCKS!"
I said that mostly in regards to home theater systems. In homes you can usually afford the space to get a decent sized speakers so the need to go with tiny satellite speakers and one sub is nill. Unless you live in a shoebox, bigger speakers always sound better if you have the wattage to push them.
In a car, you don't have that much space available so I understand the compromise. Bose would actually be keenly positioned to design an appropriate sound stage. Comparing the Bose stereo in my Bolt to other oem systems I've heard, Bose sounds pretty good. It doesn't hold a candle to a real aftermarket system with about 1000 watts of power, component speakers and a subwoofer... but it's not trying to. For a factory system, it sounds damn good. It's way better than any OEM Sony or OEM JBL systems I've heard.
