Can I use an amplifier which provides less power than my speakers need?

If you use a lower rated amplifier than your speakers, your speakers won't be able to be as loud but won't suffer any damage.

Will an amplifier which provides less power than the speakers call for work correctly?
Yes but there will be less quality then the speaker is capable of.
What size amplifier do I need to power 2 15 700w speakers RMS output power is 350w?
The speakers will work with any amp that outputs less power than 700 watts.
What happens when two 250 watts speakers are connected in 75 watts amplifier in parallel?
They will work OK. When a speaker is rated at 250 W that is only a maximum and speakers will work will less audio power. Putting two speakers in parallel will double the total audio power output for a given volume setting.
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.
What happens if you put a small amp to huge speakers?
The impedance of even large speakers is still likely to be around 10 Ohms or less. A small amplifier will only be able to drive them a little. The only effect should be that the sound will be weak - but only when compared to their max. BUT, a background radio for example delivers about 50 mW of power. Even a small amplifier will produce a few Watts of power. The electro - acoustic efficiency of a loudspeaker is about 10% - even less for a high fidelity speaker. So you will still have the output that your amplifier is capable of.
What happens when two 250 watts speakers are connected in 75 watts amplifier in parallel connection?
They will work OK. When a speaker is rated at 250 W that is only a maximum and speakers will work will less audio power. Putting two speakers in parallel will double the total audio power output for a given volume setting.
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".
If you replace a 4 ohm speaker with an 8 ohm speaker can the amplifier blow the speaker?
A1: The output impedance of a power amplifier is always less than 0.1 ohms. There are no 4 ohm amplifiers on the market! A2: I actually just bought a new car radio/CD player that specifically shows 4 ohm speakers on the sticker. It is designed to work optimally with 4 ohm speakers. If you use 8 ohm instead, it will work, but you will not get the full power output that is specified. The amp can only kick out so much voltage and so much amperage - if it is designed for 4 ohm speakers, and 200 watts (stereo, so 100 watts per speaker), it can supply 20 volts (P = V^2 / R). If you used 8 ohm speakers to this amplifier, each speaker would only get 50 watts powered at full output voltage. Alternatively, if it is designed for 8 ohm speakers and 100 watts per speaker, it can provide 40 volts. If you used 4 ohm speakers instead, each speaker could be given 200 watts at 40 volts, resulting in severe overheating and damage to the amplifier.
How many watts will power two 10 inch 800 watt speakers?
Up to 1600 watts amplifier. Less wattage will still power speakers but at a reduced volume level. Wattage is power. If you expect to fill a living room with sound, it would only require about 200-500 watts with good quality speakers. If you want to fill a banquet hall, then you would probably be looking at thousands of watts 2000-10000 watts depending on size of hall.
Can you play 8 ohm speakers on a 16 ohm amp?
There is no 8 ohm solid state amp. Really! The output impedance of such an amp will be arround 0.4 ohms. Scroll down to related links and look at "Interconnection of two units- Voltage Bridging - Zout < Zin".You can, as long as the amp's impedance is much lower to the speaker(s) total ohm load you're fine. We have never impedance matching there.
Is it ok to hook a 16 ohm Speaker up to a 8 ohm amp?

A2: I actually just bought a new car radio/CD player that specifically shows 4 ohm speakers on the sticker. It is designed to work optimally with 4 ohm speakers.

If you used 4 ohm speakers instead, each speaker could be given 200 watts at 40 volts, resulting in severe overheating and damage to the amplifier. This applies to your case as well: it is OK to hook up higher impedance speakers to a lower impedance amplifier, but you will get less power delivered. If you do the opposite (lower impedance speakers to higher impedance amplifier), keep the volume low or you could burn out the amp.
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".
