Guys , thats a big myth. I've used all types of speakers & had no problems ever. It's not burnt up any of my radios & I've used 4-6-8-& even 12 ohm speakers on all of my different cars . I think it's someone tyring to get us to buy the old speakers to make some money. I have 8 ohm speakers in my 73 GTO with a factory am/fm stereo for the last 20+ years & it still works as bad as it did when I put it in. No better no worse then the original am radio that came in the the car when I bought it new.
See this site: http://www.turnswitch.com/speakers.htm. They says that older Delco radios need 8-10 ohm speakers. 4 ohm speakers have less resistance that will draw more current and cause the amplifier transistor to run very hot.
