: Can someone explain to me what the practical meaning of ohms is, aside from resistance. I mean, is it true that if I have two 4 ohm cabs that I should have an 8 ohm output?
For max power transfer the ohms on the amp should match the total ohms of your
speakers. If your amp puts out 200 watts rms at 4 ohms then for max power you
would need either
a 4 ohm cab or two 8 ohm cabs in parallel which equals 4 ohms. I don't think
you really wanted a technical explaination, just a practical one. By the way you
should never run your amp at an impedence (ohms) lower than suggested by it's
specs. If it says 4 ohm is the lowest you should go, don't run it with a 2 ohm
load ( speakers) and expect it to live very long. Hope this helps.
