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.

How do you select speakers with respect to the impedance of the amplifier?
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.
Can you wire four eight ohm speakers to four ohms?
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.
What is the best set up for two 8 ohm 1600w speakers and a 500w amplifier with outputs at 4 ohms 5.2ohms or 42 ohms?
Use 5.2 ohms, which is the closest to 8 ohms.
Can I safely run 4 x 4ohm speakers with an 8 ohm rated amplifier?
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.
What happens if you connect 3 ohms impedance speakers to a 8 ohms impedancece 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".
How many speakers can go into a single stereo system?
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.
Best match of amplifier with speakers?
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.
How many 30watt speakers can a 240watt amplifier drive?
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
What happens if you connect 4 ohms impedance speakers which are 40 w RMS and 200w MAX to a 8 ohms and 30 w impedancece amplifier?
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.
Will 2 16 ohm speakers work with a 4 ohm amplifier?
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".
Can you run 4 70w speakers on a 150w amp or will it blow?
It's entirely possible to use four 70W speakers with a 150W amplifier but the method will depend on the speakers and the amplifier specification. We will assume that the amplifier will deliver up to 150W per channel, so two speakers will be used on each channel. If the amplifier is rated to drive a 4 ohm load, then two 8 ohm speakers can be wired in parallel and connected. In this instance, take care NOT to drive the amplifier too hard. It will overdrive the speakers at about the same time that it will begin to show a distorted output. This is a condition that can easily damage speakers so be very conservative with the volume control. If the speakers are 4 ohm speakers, they can be wired in series to provide a total impedance of 8 ohms. If the amplifier is rated to deliver 150W into 4 ohms, then the total power to the speakers will be lower than to a single speaker. The benefit is that no speaker can be over-driven and there is a good amount of headroom for safety.
What is 8 Ohms Stereo per channel?
Home stereo systems are usually built to work with speakers that have an impedance of 8 ohms, Car stereos are usually adapted to power 4 ohm speakers. You need to get this right if you want to keep your amplifier happy.
