I'm the last thing from a car guy, but am a bit annoyed with the quality of the audio (base audio package I assume, as there is no 'harman kardon' or 'inifiny' logos on anything). Anyhow, given that I'm a bit of a cheap ass when it comes to this sort of thing, I was thinking of checking wrecking yards for cars with compatible speaker systems to see if they have premium versions of speakers laying about in a yard for cents on the dollar. Does anyone know if other cars in the Kia/Hyundai line of cars share the same speaker kits (size/configuration).
