Ohms and Impedance


Ive also heard about OHM’s and Impedance. What’s that about?
Amps and speakers require a matched resistance. This is measured in ohms, and often referred to as the amps impedance. The most common impedance is 4 ohms. Dropping the resistance can put up the power a lot, providing both your amp and speaker can support the lower resistance. Also, you can connect up the speakers in parallel or series on the same channel to manipulate the channels impedance. Wiring speakers in parallel halves the impedance. So you can wire two 4 ohm speakers in parallel on a single 2 ohm channel and have them powered ok. But this is much more complex than it sounds and not recommended unless the amp’s manual and the speakers says it’s safe.

Ok I hope you’re still awake and with me. There’s only a little more to go now you’ll be glad to hear.
