It depend... When I bought my gt 95 it came with Mach 460 sound system which was top of the line back then... It is a good system but I put new speakers in and everything! Mine had a cassette player with tweeters on top of door and then speakers around the car... Most likely, get new speakers for your car unless you don't listen to music that often!
