Short Answer:
Try to get speakers with an RMS wattage rating roughly equal to the RMS wattage rating of the amplifier (per channel).
Further Information:
If you amplifier puts out 75 W RMS per channel, get a speaker that can handle 75 W RMS. If you get a speaker that handles 150 W RMS per channel, you will find that the amplifier doesn't have the power to make it sound as good as it could / should. Also, lower frequencies (where the amplifiers wattage rating is put to test) could burn out your amplifier.
The opposite is also true. If the speaker can only handle 25 W RMS and you hook it up to a 100W RMS amp the amp might send so much current through the speaker coil that the coil wires heat up, burn off their coating and short together. This, in my opinion, is much less likely to happen though.
NOTE:
An amplifier doesn't put out its rated wattage all the time. The amount of wattage dissipated by the speaker varies directly and greatly with the music. A Flute solo for instance being played with a huge 1000 W RMS amplifier might just put out 20 W RMS during the solo. But when the big organ kicks in jumps to over 900 W RMS.

Your speakers will handle 400 watts but start to disort at 200 watts?
The speaker impedance does not match the amplifier's specified speaker impedance.
Can you power 8 ohm speakers with a 4 ohm amplifier?
Yes, but you won't get rated pwer. Best is to match the speaker to the amplifier.
What speakers match a 300 watt 4 channel amplifier?
The ratings for the speakers will depend upon what '300 watts' means. If the amplifier develops 300 watts RMS total across 4 channels, this would indicate 75 watts RMS per channel. Speakers rated at 100 watts should suffice for this amplifier.
Is a 4 ohm subwoofer better then a 8 ohm subwoofer?
You need to match the speaker with the amplifier. Better or worse is not the question. The question is dynamic range and the possibility of overloading the amplifier. If the amplifier is rated 4 ohms, use a 4 ohm speaker. Same for 8 ohms. Do not "mix and match".
Is 4 watts loud?
4 watts is the power to the speaker from the amplifier. Without knowing the intensity, a wattage rating tells you nothing. 4 watts is the peak range of the speaker (the point where the output becomes distorted). The range of the audio being played varies from 0-4 watts maximum. The best way to measure the "loudness" is to go to a store and listen for yourself.
Does the Rockford Fosgate 12" sub have to have an Amplifier over 50 watts?
For optimal performance, match the amplifier's power output to the rating of your subwoofer. The Rockford Fosgate 12" starts at a 150-Watt rating.
How many watts does a alpine 3513 amplifier have?
2x20 Watts
How loud does a monster amplifier get?
A monster amplifier is about 500 watts, which means the amplifier is louder than most.
Will your 500w amplifier blow your 250w speaers?
Possibly, if you turn the volume up, but not necessarily. You should attempt to match impedance (your amplifier is designed to have specific speaker impedances connected, if these are not connected it will not deliver full power).
How many watts can the Rockford Fosgate Prime 2-Channel Car Amplifier handle?
The Rockford Fosgate R150-2 2-channel amp puts out 50 watts RMS per channel to your speaker system, or you can bridge it to supply 150 watts RMS to a subwoofer.
How many watts does a speaker consume?
An audio speaker is usually powered only by the audio signal that comes via the leads from an audio amplifier. The average power in an audio signal is usually about 1% of the peak power, and even with loud music the average power is only ¼ watt or less. But the amplifier must be designed to supply the peak audio power and amplifiers are usually rated at 25-50 watts.
What gauge speaker wire for car amplifier install?
Depends on the output of the amplifier.
