I have a 2006 SS and have heard that some cars came with the Bose audio system from the factory. Initially I assumed my car did as well since it's a loaded SS, however I do not see the Bose logo anywhere on the car. My last car had a Bose system (Mazda6 Grand Touring) and it prominently said Bose in several different places.

 

No one has any idea? All I wanted to know was if my system is by Bose or if it's just some general GM/Delco system, and I thought Monte Carlo Forum would be the place to find out.

 

Mine looks a lot like yours - 5 disc, XM, MP3, with an amp in the trunk. No Bose. RPO codes in my car are:
US9: RADIO AM/FM STEREO, SEEK/SCAN, RDS, MULTIPLE COMPACT DISC, AUTO TONE CONTROL, CLOCK, ETR, MP3 STEREO W/MULTI CD PLAYER(US9)
U87: SPEAKER SYSTEM,CUSTOM,PREMIUM PREMIUM AUDIO SYS(U87)
U2K: DIGITAL AUDIO SYSTEM S-BAND DIGITAL S-BAND AUDIO SYS(U2K)


Check on the RPO code sticker in the trunk. A quick search of Bose RPO codes got me a few refernces.

UQ4 : SPEAKER SYSTEM, BOSE, 4
UQ7 : SPEAKER SYSTEM, PREMIUM PERFORMANCE, ENHANCED AUDIO, BOSE
UIT : Delco-Bose stereo
UL9 : RADIO, AM/FM STEREO, SEEK/SCAN, AUTO REV, MUSIC, SEARCH, CASS. CD,
AUTO TONE, CLOCK, ETR, BOSE
