I need some information.  I have a reciever that I can hook up to 4 spkrs to 
in twos sets (A & B).  It says "A or B, 4ohms minimum per speaker"  "A AND B, 
8ohms minimum per spker."  I have a pair of Polks in there right now which 
are 8ohms but I also have a set of car spkrs i would like to add.  I think 
the car spkrs are 4ohms though although it doesn't say so, i heard somewhere 
that most car spkrs are 4 ohms (correct me if i'm wrong).  Can someone 
explain to me about what ohms are and what would happen if I connect my car 
spkers to the reciever with the Polks?
Thanks.
