    Hi,
    I've just bought this cab and an Ironball head.
    Here's a picture of the back:

    I'm not sure how to connect them... and I'd like not to blow up anything.
    Is the Input input of the cab (left one) a 16 ohm input?
    What about the Thru input (right one)? Is it an 8 ohm input? Can it be used by itself? How can I use it?
    Thank you!

    Thru is meant to chain it with another cab. So hook your amp 16 ohm output to the cab's input jack.

    The input is a 16ohm input.

    The "thru" is more than likely an output jack - definitely not an 8 ohm input. Opening up the back might give you a better idea.

    It says everything you need to know right on the jackplate. It’s wired for 16 ohms. Use the 16 ohm tap on the amp, and plug into the Input of the cab.

    If you ever decided to buy a second 16 ohm cab, you could use another speaker cable from the Thru jack to the Input of the new cab.

    OK, so I've got a 412XXL with a similar backplate, but 8 ohm. If I were to use the thru to another 8 ohm cab, what ohms should be sent out of the amp? 16, right?

    The thru (or link, or whatever they call it) jack is parallel, and loads in parallel half, so two 8 ohm cabs in parallel is 4 ohms.

    Likewise for OP’s cab, if he got another 16 ohm cab he could connect it to that cam from the ‘thru’ jack, and the total load would be 8 ohms.

    Fuck, I'll never get the hang of this. At that point I might as well just use the two 4 ohm jacks on the back of the amp.

    Yep, if the amp has two jacks on the back, these are also wired in parallel so no difference between one cable from 4 ohm jack to each 8 ohm cab, or just one cable from 4 ohm jack, to one cab, then another cable from ‘thru’ to the next 8 ohm cab.

    The ‘thru’ jack on the cab is useful for amps with only one speaker jack, or when your cables aren’t long enough.
