okay, so if my speakers measure at 5 ohms on a meter, are they condsidered 8 ohms? and to get a 16 ohm 4 x 12, would i need to wire them all series, or should i do 2 pairs in series, parallel with each other? hope that makes sense. if the speakers are comsidered 4 ohms, ill just put all four in series and be done with it. thanks.
