Actually TD that is the stocker Delco HU that came with most Bose speaker packages. My 03 GTX came with the Bose sound system and had that exact same HU. I switched it out in favor of the 5 channel EQ stock model though. The Treb and Bass only sliders really dont bring out the performance of the bose speakers, not that they are high end by any means. But the 5 band EQ stocker really made up for what that HU lacked.Originally Posted by TDCRacing
However in the 97-03 models you had two choices of stereo HU's, the one pictured above and the 5 band EQ version. Neither HU was "stamped" as a bose HU, but most of the ones that had the bose speaker setup in it had the HU pictured above.
Just my observation on what I have seen over the years in regards to the stock HU's in the 97-03 GPs.
