What Sound System Do I Have?

[crhoads]

I have the original sticker from my truck.  It says Bose Premium Speakers.  It does not talk about "Premium Sound" system or anything else.  By the codes in the glove box can I tell if I have the

a.) Premium Sound System.
b.) Basic
c.) Lux

I pulled the cup holders out and felt down on the floor and I really think I felt an amp shaped like the "Premium Sound" system.

I have an 06 Tahoe which is obviously the same truck as the AV inside.  I can't find any good Tahoe forums either.

Thanks Bros....

The luxury sound system is only available in Denali's and Escalades. Exception is the 03 H2's and Trailblazers.

There are some more detailed exceptions to this, however no Lux systems were factory OEM in Av's or Tahoes.
