You don't say what kind of car but I would guess a Firebird with a Monsoon system. The symptoms indicate that the Monsoon amp isn't working (the amp powers all speakers except the tweeters in a Firebird). First check the RADIO ACCY fuse in the dash fuse panel. Always use a fuse tester or replace with a known good fuse because a fuse can look fine even when blown. If the fuse is okay then you'll have to do some checking at the amp in the right quarter panel area (in front of the spare tire). It's possible it was unplugged during repair and not reconnected.
