Yes you can. Contrary to popular belief, an amplifier rated with a higher output than the speaker rating rarely damage the speakers. If the amplifier overdrives the speakers, the sound quality will be dramatically affected. Most listeners will turn the level down to reduce the distortion being heard. The amplifier's power rating is the maximum power that it can produce and it does not mean the output power will be at that level.
On the other hand, an amplifier that is overloaded will deliver distorted signals to the speakers. At high power levels, the distortion can be damaging to the speakers in a way that simply over driving a speaker is not.
Therefore, it is as safe to use an overpowered amplifier with speakers as it is an amplifier that is rated at the same power or even lower power than the speakers.

Can you blow out your speakers if you use the wrong power amplifier?
Speakers can be blown if the wrong power amplifier is used and damage can be done by either overpowering or underpowering the amp. For example, if the power rating of the speaker is 300 watts capacity you will need a 300- to 600-watt amp.
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.
How many watt amplifier will power two 15 inch speakers?
50 watts is a good amplifier size for use in the house. For other applications speakers usually have a power rating.
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.
Can you use a400 watt speaker with150 watt amp?
You can, but the problem is your speakers will not give their optimal sound quality because your Amplifier is too weak for the speakers. So,buy an amplifier with an output power rating high then 400w.
How do you connect 2 6 ohm speakers to an 8 ohm amplifier?
You can, but its power output will be a bit higher than its 8 ohm rating.
Can a 15 watt amplifier power 300 watt speakers?
Yes it can. The rated power of the speakers is the MAXIMUM that can be applied. If more power is supplied, damage can occur. Either the speech coil can blow or mechanical damage to the cone or suspension units.As the amplifier is below this rating, it will not supply more power than the speakers can handle and will be perfectly safe.
Can you twist more speakers in line with the existing speakers By this you mean the plus and - clamps for speaker wire on the system you would be adding two wires to each Both are 4b speakers or some?
Yes, but you should be careful not to exceed the amplifier's mininum impedence rating for each channel. If your amplifier is rated down to 4 ohms, you cannot connect more than two 8-ohm speakers on to each lead. Doing so will damage the amplifier. Connecting two 4-ohm speakers will drop the impedence down to 2 ohms, which is lower than most home amplifiers will tolerate.
Things to Consider When Purchasing a Stereo System?
No matter what musical genre you like the best, a stereo system can help to enhance your listening experience. From speakers to amplifiers, stereo systems come in various forms, and it is important to understand the components involved when searching for a stereo system to purchase. While the size of the speakers on a stereo system is important, matching those speakers to the correct amplifier is just as important. Furthermore, bigger is not always better. As sound engineering technology has continued to improve, manufacturers of audio equipment are finding ways to deliver deep, rich sound in a smaller, more compact set of speakers. In the past, one would need to purchase very large speakers that would be housed inside of a cabinet in order to achieve these results. However, today, this is simply not the case. When looking for speakers for a stereo system, it is important to know the wattage they can handle. This will help you to decide which amplifier you will need to use in conjunction with them. Speakers can range in size from a few inches to a few feet in size, so understanding your space requirements is important as well. If you are purchasing speakers for a stereo system for your car, you will need to find the smallest speakers with the largest wattage rating to get the most for your money. If you are purchasing speakers for a stereo system for your home, you may have a little bit more room to pick and choose. In terms of purchasing an amplifier, again, it pays to know how it will correspond to your speakers. If the amplifier has a wattage rating higher than what the speakers can handle, you may risk doing damage to the speakers, the amplifier, or both. You may want to consider asking an expert before purchasing a stereo system to ensure that all of the components will work well together. Finally, consider your power source. If the amplifier will be installed in a car, you may need to purchase a separate battery to power it. However, if the amplifier and speakers are being placed in your home, ensure that your power outlet can handle them before plugging anything in.
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.
How do you figure watts for 8 Ohm speakers?
The power rating of speakers has nothing specific to do with ohms. look at the Watts rating printed somewhere on the speakers
What size audio amplifier will you need to buy to power four 60 watts speakers 8 ohms impedance Frequency Response 120 Hz - 20 kHz?
There are several ways to drive four speakers. For simplicity, this answer assumes that the amplifier will be a two channel stereo amplifier - one channel for left and one for right hand channels. It also assumes that the speakers will be connected in parallel, that is, both positive terminals wired together and both negative terminals together. The two speakers together will be the equivalent of a four ohm speaker. First, make sure the amplifier is rated to drive four ohms to both the left and the right speaker. Most amplifiers will handle a four ohm load but some are aonly designed for eight ohms. The manual will tell you what the amplifier can handle. The speakers can handle up to 120 Watts per channel when two are used together. To fully drive the speakers, an amplifier of 120W per channel will be needed. However, that is the worst possible size of amplifier to use if you are going to run the system near its peak power output. Here's why: Speakers are able to cope much more power than their rated power. The sound will be terrible but generally, the speakers will not be damaged. Speakers can also cope with a distorted signal from an amplifier as long as the power level is a lot less than the rated speaker power. However, overdrive the amplifier when it is delivering the full power rating of the speaker and the high power distortion is very likely to cause damage to the speaker. The choice of amplifier should either be higher or lower than the speaker rating. A 30W per channel amplifier will still have a great deal of power to offer and the output will be far louder than most people would ever want in a living room. If the amplifier is over-driven, the low power level avoid speaker damage. A 200W per channel amplifier will drive the speakers harder but with a clean signal. If you want to run the speakers close to their maximum level, choose an amplifier of this power output or higher. A note about power levels: True power output is always measured as an RMS figure. Music power is approximately twice RMS power and peak music power is about twice the level of music power. Therefore, if the speakers are rated at 60W peak music power, they actually have a rating of just 15 Watts RMS. When comparing amplifiers and speakers, always make sure you use the same units, RMS, Music or Peak Music. Never mix them.
