does anyone know how many and what sizes the speakers are in an 81 300CD. im looking to take out and replace all existing speakers with better quality ones but i am not sure about the sizes because they are all covered up by the dash or some piece of interior. any info on this would be great. Thanks. and does anyone know if a reular size cd player can fit in the slot where the radio is. it looks like it would be a tight fit so i am not to sure on this.
