the watts for 2 ohms is more than 4 ohms. depending on the ohms your speakers take up and the wattage the speakers use, tells you what size amp you need.
Amplifiers are rated to operate within a range of impedances. Typically, a domestic amplifier will drive a minimum impedance of 8 Ohms or 4 Ohms. Using speakers that have an impedance lower than the amplifier rating is likely to increase distortion and can damage the outputs of the amplifier if the levels are too high. Using speakers that are significantly higher than the minimum rating will not cause damage to either the amplifier or speakers but it will reduce the power that is delivered to the speakers. In most domestic systems, this limitation of the power output is not likely to be an issue. Any amplifier rated to drive into 4 Ohms will work well with speakers of between 4 and 8 Ohms. An amplifier with an 8 Ohm rating should be used only with speakers of 8 Ohms or higher.
I presume you mean wired to four ohms amplifier output: In this case, pair the two speakers in in series which will make the give you 18 Ohms and then join the two pairs in parallel which will result in approximately eight ohms. Then connect then in that format to the amplifier. It will work for you.
For a 500-watt, 2-channel amplifier, the speaker impedance you need depends on the amplifier's design and configuration. Common speaker impedances are 4 ohms and 8 ohms. If your amplifier is rated for 4 ohms, you can use 4-ohm speakers for maximum output. However, if it’s designed for 8 ohms, using 4-ohm speakers may lead to potential damage, as it could push the amplifier beyond its limits. Always check your amplifier's specifications to ensure compatibility.
Use 5.2 ohms, which is the closest to 8 ohms.
Not really. The only possible configurations of four 4 ohm speakers is 1 ohm, 4 ohms, and 16 ohms. This will not match an 8 ohm rated amplifier. It will work, but you will not achieve rated power output, and you run the risk of damaging the amplifier.
Sorry, but there is really no amplifier on the market with 8 ohms output impedance. The output impedance of a power amplifier is always less than 0.5 ohms. We use no impedance matching. We use voltage bridging. Scroll down to related links and look at "Interconnection of two audio units - Power amplifier and passive loudspeaker".
All amplifiers are rated to handle a certain speaker impedance. The majority of loudspeakers have an impedance of 8 ohms while most amplifiers will be able to drive a minimum load of 4 ohms. It is important to check the ratings of the amplifier before adding more speakers. If two 8 ohm speakers are wired in parallel, the total impedance will be 4 ohms. If 3 speakers are wired in parallel then the total impedance will reduce to around 2.5 ohms. If the total speaker impedance is lower than the rated impedance of the amplifier, it is quite possible to damage the amplifier as the output level is increased. To be safe, make sure you understand the impedances of the speakers and the amplifier's rating before hooking anything up.
I always try to match an amplifier or receiver that is rated within the following range: from .8 times to 1.5 times the RMS rating of the speakers. The impedance of the speakers should not be rated below 5 ohms unless the amplifier/receiver is conservatively rated as 4 ohm stable.
Depends on the amp and type of speakers brand and ratings would be nice info u also need to look at ohms of the amp and the speakers
The Kenwood KAC-923 amplifier delivers a maximum power output of approximately 300 watts at 2 ohms and about 150 watts at 4 ohms. It is a 2-channel amplifier, making it suitable for powering speakers in a car audio system. For optimal performance, it's important to match the amplifier's output with compatible speakers.
If the amplifier is not rated for 4 ohms impedence, you will quickly over-current the amp, burning out components. The power handling of the speaker and power output of the amplifier does not matter in this case. It must be compatible with the impedence load that you are connecting.
There is really no amplifier on the market which has an output impedance of 4 ohms. The impedance of an amplifier is always less than 0.5 ohms. We do not use matching, we use bridging when we connect the amplifier to the loudspeaker. Scroll down to related links and look at "Interconnection of two audio units".
