Thread: 1998 Grand Prix GTP sound system

In 97 & 98 there was 3 options. A 4 speaker in some SE's & base GT's. A 6 speaker Delco was the most common and available on all trims 97-03 and does not use an amp. The last 97 & 98 option was the 8 speaker "Delco Premium" unit that had a small amp behind the glove box which powered the rear 6x9's but none of the other speakers. If you have 4 speakers in your back window you have the Delco Premium system. There was no Bose offered in 97 or 98.

Starting in 99 the Bose system was available and the Delco Premium was dropped. The Bose used a trunk mounted amp that powered all the speakers. Monsoon became an option in the 04+ GP's.
