Speaker spec.What is the definition of 4 ohm,6 ohm and 8 ohm & compactible with Amplifier requirement ???

As everyone has said, the ohm load is the resistance of the system. There are actually two different ohm loads in a sound system. The ohm load that the receiver is rated for, and the ohm load that the speaker functions at. A speaker rated for 8 ohms will have an 8 ohm load at roughly 1k in the sound band. Highs producer a larger ohm load and lows produce a lower load. A speaker rating is approximate because every sound that you hear carries a different load to it. If you want to play around with this meter a speaker with different volatages and tones and see what happens. Most amplifiers will take a 2.67 ohm load without a problem. This means that you could wire (in theory) 3 sets of 8 ohm speakers in parallel (both pos together both neg together.) Wiring speakers in series (pos to amp, neg to next speaker pos, neg to amp) would increase your ohm load.

Really in today's receiver ohm ratings are very unimportant unless your doing a very complicated system in which case you should understand these things already. The one thing that does slip by most times is that the ohm rating of a speaker is directly related to the quality of a speaker (again, in theory.) A speaker that does not operate too efficiently will not reproduce "crap" in the line too easily. It will take more power to push a higher ohm load, but it's a purer sound. (cars use 4 ohm loads, homes use 8, professional monitors are 16-32 ohms, notice a trend.... for the record Bose is 2 ohm rated.. go figure)

Lots of wrong answers here. You won't damage or in any way harm your system by running a higher ohm load than rated. What happens: The amp puts out voltage and has amperage potential. You can put an impedance of 100,000 Ohms on the amp and turn the amp up with a sine wave, and you will see the voltage rise. As the impedance lowers, you don't swing higher voltage, you pass more amperage. As the impedance continues to lower, the amperage can increase to destructive levels. That is why you must not go lower than rated on the ohms, but higher is fine. If you look at high-end stuff, they talk about the amperage potential, and this is only used in low-ohm speakers. Long answer, but it should make more sense to you as to WHY 8 ohm speakers are fine when mated to a four-ohm amp. The power potential of the amp is reduced (you won't have as many watts), but that just makes the amp's life easier! Hope this helps!

How to match amplifier and speaker with regards to ohm rating and are they interchangable.,and the cause and effect

Speaker Definition

Speaker resistance (in ohms) is the load you will be putting on your amplifier. If the load is more, the sound will go down. But, if the load is too low (though, with less load and at medium volumes), you might get better sound but, might blow the speakers at high volume. So, it is important to match the resistance.

If you are using a low power amplifier say 10W RMS with required speaker rating of 8ohm and a speaker of 4ohm 250W. It might work without any problems. It is very important to balance the wattage and the resistance especially, with high power amps.

With old tube amplifiers and some modern amplifiers with FET outputs it is important to match the output impedance of the amplifier with the speaker impedance for maximum efficiency and minimum distortion. Modern transistor-output amplifiers are not sensitive to speaker impedance, and will produce higher output power with lower impedance speakers. Amplifiers are usually rated for 8-ohm speakers, and will have more than enough power for 4 or 6 ohm speakers. One caution: the amplifier (if marginally designed) may not tolerate low-impedance speakers, so be sure to check your amplifer specifications before using 4-ohm or lower speakers. It could cause some amplifiers to overload.

the ohm signifies the impedance of the speaker meaning the wire resistance.

the most compatible speaker impedance for the amplifier is matching its specific impedance (usually used is the 8ohms). Some amplifier makers, specially those used for car sound setup, make their amplifiers have the ability to change its impedance depending how you want to connect it (bridging); speakers too, have that ability to change - connecting it in series or parallel will change the speakers impedance (computed as a whole unit; not individually).

Changing the rated impedance will definitely affect your amplifier and/or speaker's performance. And not all is advantageous for both devices.

Better setup those normally to prolong the life of the device.

goodluck!
