    Okay, so I got this cab and on the back the ohms switch has been taken out. What ohms is this running on now? 4, 8, or 16? Need to know so I don't blow my head up.

    Do you have a multimeter? just attach your speaker lead and measure the end of it. The very tip is positive, the shaft is negative.

    Will not make any difference which way round you have your multi-meter probes

    If your reading is from 6 -7.2 ohms, that's an 8 ohm cab. From 12-14 ohms is a 16 ohm cab.

    They don't read exactly at 8 or 16 when cold.

    First thing I'd do is take the back off the cab and check everything. Check the speakers all tally, I've seen a lot of replaced spks some even different ohms to the rest, more importantly check the wiring and how they are wired. Seen some monster wiring jobs were people have cut the wires on those switch sockets and just taped the wires up with insulating tape.

    There is a difference between resistance and impedance guys.

    Thank you everyone for your replies. So what should I check for? As far as resistance goes I don't know much, and I get impedance, I just need to check the speaker outlets with a multimeter to see that? How do I check resistance?

    If you dont know the basics i would suggest that you find some that can do it for you, a decent tech will check it for you

    Resistance is measured in ohms. Use the ohms setting on a multimeter.
    Will not make any difference which way you have your multi-meter probes.
    You can do No harm measuring resistance on a speaker so no worries there.
