Stock speakers vs Aftermarket

[TKoZ]

Hey guys, I own a 98 GP GTP, and one of my 6x9's blew in the back. Can I still buy those anywhere? If i must, ill upgrade to aftermarket ones with a new radio. Any recommendations on some good 6x9s? Also, i know my GP had the hi-performance audio option from delco, but whats the difference between the hi-performance and the normal delco audio system? Thanks!

Hi performance = bose?

If so, you need to find some bose speakers from someone on the forum or from a junkyard.

Im looking at the 1998 GP sales brochure..yes i still have it.. but it said it came with the normal delco system, the hi-performance delco, and the Bose hi-performane. I dont have the Bose, but i know i dont have the normal delco ones either. I Wonder if the difference was in the amp?
