    I have a 4x12 Marshall cabinet with 4 16 ohm G12 H 30 watt speakers all 16 ohms. Can I wire them to end with a 16 ohm load?

    Series/parallel or parallel/series, yes this is done by nearly all Marshall 4x12 cabinets (with some 8 ohm V30 exceptions I guess)

    I'm not quite sure what you meant (parenthetically), but if the speakers are 8 ohm, you can not make four of them come out to 16 ohms.

    I mean, there a few 8 ohm 4x12 Marshall cabs that have 8 ohm V30s, like the silver jubilee.

    Right you are my friend! :cheers: I was merely pointing out that your other post almost alluded to being able to wire those 4x8 ohm cabs for 16 ohms. I'm well aware that you know what's what, but simply clarified for those who might not know! :D

    Yes. Check schematics on line. I did it with my carvin cab. And my b52 as well. Found a schematic on line. Even bought a low reading ohm meter. Never be to carefull. Hope that was helpfull

    Wire two sets of 2 speakers together in parallel that will make each set 32 ohms. Then wire the 2 32 ohm sets in series. That will drop your 4 speakers to 16 ohms. I was worried about hurting my tube amps I used to have. Found s schematic for it. Solid state amps and high bred amps can either match ohms or run lower ohm amps into higher ohm speakers. Not the other way around. It can hurt amp.

    right idea, but you've got it backwards a bit...

    2 x 16 ohm in parallel is 8 ohm
    2 x 8 ohm in series is 16 ohm

    2 x 16 ohm in series is 32 ohm which doesn't apply to your hook up...

    He wanted to wire 4 1
    6 ohm speakers to keep them 16 ohms. I should be deaf from guitar amps.

    That is definitely wrong, even if the end result is the same (for a 412).
    Two same impedance speakers in parallel halve the total impedance.
    Two same impedance speakers in series double the total impedance.

    It is important to get this right with SS and tube amps.
    Misinformation can be damaging.
    With SS you could go below the Min load.
    With Tube you could mismatch the required load.

    I was under the impression,
    That a 412 -16 ohm wired in series /Parallel remained 16 ohm ?
    But if you added an additional cab of [email protected] ohm wired s/p > -together -IE (full stack) 812-16ohm wired mono
    = 4 ohm ? Or is it 8 ohm for full stack?

    Two 16 ohm cabs together in parallel is 8 ohms total.

    Marshalls, Fenders, Orange amps that have paired output jacks always have the pairs connected in parallel.

    There have been a few amps with series paired output jacks (MusicMan HD), but those are always clearly labeled as series connections.

    Just piling on for clarity -- almost everything in this post is wrong.

    Besides getting series and parallel backwards, hybrid amps (high bred? LOL) can have solid state preamps with tube power outputs, where matching impedances is just as important as any other tube amp.

    Sold state outputs are labeled with minimum impedance. Full power is only generated into the minimum impedance, and output drops when driving higher impedances. 100w into 4 ohms becomes 50w into 8 ohms, 25w into 16 ohm, roughly speaking. If you plugged that amp into a 2 ohm load the output section would try to pump out 200 watts, overheating the power supply and/or output transistors.

    I keep my ohms under or even with my cab. If it was a all tube amp definitely match ohms. I lose wattage if I'm using lower ohms.

    Sigh...ok, here you go, Scumback wiring diagrams for 4x12's on the bottom.
    http://www.scumbackspeakers.com/wire.html

    Four 16 ohm speakers can be wired in parallel/series to 16 ohms, and in series/parallel to 16 ohms.

    Four 8 ohm speakers can be wired in parallel/series to 8 ohms, and in series/parallel to 8 ohms.

    Two 16 ohm cabs wired to an amp head (assuming standard parallel speaker output jacks) results in the amp head needing to be set to 8 ohms. If you have two 8 ohm cabs, then set the amp to 4 ohms.

    You're welcome. Whenever I wire cabs I like to go red/black (pos/neg) or white/black (pos/neg) wire sheathing so I can see when I screw up....and trust me, I've done it enough times to pay my graphic artist to make these files. Glad I could help you out.
