I have a rockford fosgate subwoofer and was wondering if there is a way to find out if the subwoofer is 4-ohm or 8-ohm because there is no model number on the subwoofers. So i don't know wether it has one or the other impedance? Any comments would help thanks.
A: Use a VOM meter in resistance mode. It will give you a close reading.

I'Ll suggest a sealed box...you'll get a better sound than a ported box
