This refers to what kind of sound system the vehicle has. Premium audio systems are generally name brand systems (such as JBL, Bose, Rockford Fosgate, etc) that have been installed inside a vehicle when it leaves the factory. Often they more advanced systems, complex wiring, factory amplifiers, and other features that can make installing aftermarket component difficult.

This wiring harness adapter worked great and clipped right together. The only problem I had was my 1991 240sx had a "Premium Sound Package" which had factory amps on the speakers. So I had to rewire the speakers anyways, but the harness wasn't to blame.

Great harness, would definitely recommend this for ease of installation.
