Thats wrong YHR 2 4's in series gets you 2 ohms which will burn the amp you need 8 ohm speakers for a single and 16 ohm speakers for doubles. Trust me on this stuff guys.
Panther you are wrong..
Parallel circuits resistance will stay the same value
Series circuits the resistance will go up.
I was in college for Electronics and this one I clearly can remember!
