The 8" headunit is much better than the 7", as are the speakers. There is no 6.

Mine's no 1000w luxury car stereo with 20 speakers, but the Bose system is pretty good for what it is.

The Cruze with premium sound vs standard sound has different speakers and a different receiver/amp? I ask because I want to upgrade the sound in my 2016 Gen 2 Cruze. I was wondering if just upgrading the speakers and adding a subwoofer would improve the standard sound system close to how the premium sound is.

Yes. With good equipment, you might even do better than the Bose system.
