In the old-days, there was a switch you would have to use to select which impedance to run your head. Some nostalgic amps still have this feature, but most amps automatically adjust. When selecting a cabinet, be sure your amp will run at the impedance your cabinet is wired for, and that you will have enough power to achieve the volume you desire. As you noted in your comment, running an 8 ohm and a 16 ohm in parallel gives you 5.33 ohms. Setting your head's output to 4 ohms will ensure a safe output current.

Last time (and only time) I plugged in a head that had a lower impedance than my cab, I had to buy 4 new speakers. The amp has less resistance (lower ohms) so the signal is stronger than what the cab is wired to accept, potentially damaging your speakers.

I have a 1973 Australian amp called a Wasp/Holden, basically a 200w Fender Bassman-a-like. It only was a 4, 8 and 16 ohm output (one of each).

16 Ohm Speakers

I run this head with an American-made Ampeg 410HE, that is 4 ohms.In my band there is an arms race. Both the guitarists bi-amp. One has a Peavey Classic 50 and a Vox AC30 and the other a Musicman 212 and a fender 410. They sound amazing and loud. In order to keep up I wanted to add another speaker enclosure, but don't think I can given that I need two 4 ohm outputs.Can anyone help?

Click to expand.Your 410 inputs are almost certainly wired parallel - wheather its indicated or not. Daisy chain away!The real question here is.A) have you been plugging the 8ohm cab into your 4ohm send?B) how loud do you guys really need to be? I'm not sure about the actual math here.but I'm not sure 100w@4ohms into 8-10s. Is going to be much 'louder' than what you have now which is roughly 130w@8ohms into 4-10s. I mean.you're doubling the speaker area, but your halving the power.Hmmm.Someone smarter than I should chime in.

I've just been out and bought an amplifier head (an old 1973 Marshall JMP50, sounds lovely) and realised that I STILL did not really understand how all this Ohm stuff works when it came to speaker cabinets. After playing electric guitar for more than 20 years and having had it explained to me a dozen times!So I've just spent a few hours reading up on all this and I'm going to try and explain it to you and hope that you will actually understand it:)The basic idea is that when an amplifier sends a signal out it is important to match the speaker and the amplifier so they are set with the correct Ohm setting. It is REALLY important with valve amps, you can do lots of damage if you get it wrong. Transistor (solid state) amps are more forgiving.If you only have one speaker box, then I guess it's pretty easy - most amp heads have a switchable Ohm (Ω) setting, so you look at your speaker box, and see what the Ohm setting is, and set your amp to that. But it get's a bit more complex when you have more than one speaker box and there are other things to consider.AMP RULE: Always use SPEAKER cable, NOT GUITAR cable.The may look the same but they are not. Use the right tool for the job.VAVLE AMP RULE #1: Don't turn the amp on without the speaker plugged in.Ignoring the rule above can screw up your amp pretty quick, so just don't do it. There are some 'power brakes' that you can use ( is great) but you should still never just turn it on without speakers plugged in.

Impedance (Ohms and stuff)Impedance measures the resistance that occurs when electricity is flowing to a load (speaker). It is shown by the greek character Omega Ω (like the watch logo!). The name kinda gives it away, the signal is impeded.Amps are designed to work with a set amount of resistance (impedance) but many amps have switches for different ohmages on the back so can work at various levels.
