? on 4-channel amp and ohms

SouthArk370Z

As per RonRizz, most amps will handle an impedance mismatch reasonably well. There will be some added distortion but, if you don't push the amp hard, it shouldn't be a problem except for with the worst-designed units. However, if pushed hard into a low impedance, it will sound bad and can cause damage to the amp and speakers. Try to match impedance as closely as possible, but a small mismatch is not the end of the world.

Keep in mind that driver/speaker impedance is given as a nominal value and will, at resonance, be lower than the spec. A 2 Ohm speaker may have 1 Ohm impedance at resonance.


Edit: Oops. Impedance is at it's max at resonance. It's at the frequencies above and below resonance that impedance drops.

Thanks for the response. While I know many of the basics, always nice to get some confirmation (and learn something new) from those with more experience.
