    Can I hook up a 2x12, 16 ohm cabinet to a Fender hot rod deluxe? Thanks

    I'm reading into your question, the 2X12 plus the internal speaker.
    Can you?.....Yes.
    Will it harm the amp?...No
    Will it sound good?.... Probably not. The internal speaker is 8 ohms. Hooking up an external cab of 16 ohms in parallel with the internal speaker (which is what the ext. cab jack does) will yield an overall impedance of 5.33 as seen by the amp. BUT the distribution of power will be very imbalanced. The internal speaker will get 2/3 of the power and the cab will get 1/3 (each speaker in the 2X12 cab will get 1/6 of the power). The extension cab will be overpowered by the internal speaker, sound-wise.

    Since the overall impedance seen by the amp is within acceptable limits, if you already have the 2X12 16 ohm cab, give it a try. Can't hurt anything.

    To be extra cautious I wouldn't run the external cab (16 ohms) by itself with the amp.

    Let us know what it sounds like to you.

    People hook up 2x12's all the time to the Hot Rod Deluxe. Sounds fantastic.

    You can try it as is and you won't hurt anything, however it might not sound great. Try rewiring the cab to 4 ohms and run it off the ext speaker output without the internal speaker. This will probably be your best option as is. I might try to get a decent 8 ohm 112. That's what you really need.

    This can be done, but if my memory serves me, you should not run from the external speaker jack ONLY. Use a dummy plug (no wires connected to it) in the internal speaker jack AND then connect the 4 ohm cab to the external speaker jack. This will provide a correct impedance match.
