The ohm (symbol: Ω) is the unit of electrical impedance or, in the direct current case, electrical resistance.
By definition from Ohm's Law, a device has a resistance of one ohm if a voltage of one volt causes a current of one ampere to flow (R = V/I).
The speakers are rated at 160 watts of power based on the resistance of the speakers being 4 Ohms.

verify to verify if the optimal output skill is 100W RMS or 100W top (track skill). The "top" or "track skill" discern is often approximately two times what the RMS skill discern may be if quoted. On a lot of amplifiers designed and meant for the yankee industry the "top"/"track skill" discern is the single oftentimes given. This makes a low powered amplifier look better on the exposure blurb. Loudspeaker optimal skill is frequently quoted as Watts RMS. back, you may desire to verify this once you purchase them. The output impedance discern would desire to be matched as heavily as achieveable to the loudspeakers. maximum "classic" radio set loudspeakers are 15 ohm. you're saying that the amplifier is switchable to an 8 ohm output, so this components a determination of 15/15 ohm or 8 ohm loydspeakers. in case you mis-journey the impedance then your audible output skill would be under you will possibly assume. purchase any pair of loudspeakers that journey the output impedance and have a skill handling skill of around 20% greater desirable than the optimal that the amplifer grants. This "headroom" is significant as a results of fact it avoids the gadget having to function on the sting of its overall performance envelope. this might ward off "clipping" and different distortions which will impact sound high quality. for the comparable reason you may desire to in no way run the amplifier at greater desirable than approximately 70-eighty% of its optimal quantity. i'm confident you would be wanting to have been in golf equipment, bars and so on the place they run their background track "flat out" and have observed the appalling high quality of the sound. The Aux a million and Aux 2 inputs are "line point" as a results of fact of this they're around 600 ohms impedance and could assume a a million volt top-top enter sign. you may feed in a "line point" sign from the different gadget, different than a micrphone, into those and it is going to artwork very nicely. The "Phono" enter is probably a intense impedance circuit which expects an rather low enter voltage. the selection of element that a typical crystal gramophone cartridge will furnish. This enter will probably even have RIAA equalisation circuits in there. do not attempt to shove the rest into it or you will get some terrible noises.

An "ohm" is the electrical resistance offered by a current-carrying element that produces a voltage drop of one volt when a current of one ampere is flowing through it.

ohms means the power passing threw the speakers nothing to do with the sound of the speaker

ohms is the internal resistance of it's coil, car speakers have 4 ohms and home speakers 8

all you need to know is that if you get to close to 0 ohms then you burn your system up and if you have too many ohms then you lose power but make the audio source last longer

OHM is the unit of resistance. It is like sayiing volts or current. good luck
