If you’re curious as to why we didn’t include information about the Sierra 1500 audio system above, that’s because the speaker system that is available to you will change based on how you configure your Sierra 1500. That’s to say, audio system availability isn’t strictly based on which trim you choose. So, while you will ultimately end up with a 2-speaker system, a 6-speaker system, or a Bose Premium Series audio system that includes 12 speakers with CenterPoint, you should speak with one of our representatives to get a clear and concise picture of what your options will be.
