<VV> speaker resistance 4 ohm, 8 ohm, 10 ohm??

[Michael Kovacs]

 I have a couple of non Vair am-fm radios I will test and install the best sounding one. Both radios say to use 4 ohm speakers, but all I have is 8 ohm. 
   
   What problems will I be creating?  I have original NOS 10 ohm speakers but wont try them.
