most radios i have worked on have have 6x9's in them but have a small speaker mag. on them less than 2" check around at an auto scrap yard and they have lots that will do the job, beside this is not a cd quality sound system... if you look around the the back of the speaker you will see what i mean about the clearance, take the old on up as a sample, the newer speaker will have 2 wires, your old one may only have one, the other lead is connected to the frame of the speaker which is not a problem to fix. besides who lookes inside the radio??
