SL2 rear speaker help

I need to get rear speakers for my 94 SL2. [serched through the audio board on this site, but mostly aftermarket info] Well the OE speakers are 10 ohms. All I can find are 4 ohms. Any place to find the higher ohm speakers, or will the lower ohm ones work with the OE radios in our cars??

Aftermarket speakers will work fine.

You could always go to a junk yard and get a new speaker. All 4 speakers are the same size.
