1969 Dodge Dart - Original Radio Speaker Ohms?

I can't find the site but I have seen it twice looking for a stock speaker for my dart.

I recall seeing that 8 ohms is correct as 4 ohms increases the current in a transistor and caused it to run hot.

I'll keep looking for the site

Thanks Dana.
I noticed the replacement speaker in my car is marked 4 ohms and when looking by the part number on line found a refurbished original for sale. That place also says its 8 Ohms.
One nice feature on the original speakers was the positive and negative terminals couldn't be hooked up in reverse.
