You always want to buy speakers rated higher than the max RMS output of the amp. I've blown plenty of speakers in my day as soon as I turned it on.
Ohms is just as important. Never connect two or more speakers in parallel. This cuts the ohms to less than half and you will blow the amp if its not designed for it . You can connect speakers in series if you like but this cuts your RMS output to less than half and also could blow the amp. One speaker per channel and keep the gain nob one level below max to be safe.
Car amps 4 ohms speakers.
House amps 8 ohms unless specified.
That answer (above) is not much help, nor true. (I wouldn't trust someone who has blown "plenty of speakers", it sounds like a poke and hope job.) Unfortunately, the correct answer is hard to obtain because the people who sell amplifiers and speakers don't always use the RMS power rating for CONTINUOUS power when describing the components. These manufacturers know that we folks are into POWER and they usually advertise the components "PEAK" power rating. WOO HOO!
But bottom line, it's easier to blow the amp with higher rated speakers because the the amp is working too hard to fill that big jug so to speak. The rule is to get an amp with about twiceas much RMS value of wattage at 8 ohms as the speakers RMS value at 8 ohms. You'll need to leave the room because your ears will be throbbing before you'd do any damage to your speakers.
But yes, it's always important to follow these steps and be sure to connect your speakers and inputs (mikes, instruments, etc.) first, AND have the power level controls SET LOW, then power up, and then adjust the volumes up until you get your sound right.
Connecting speakers in parallel is a whole different topic, but it LOWERS the ohms resistance and yes, it takes lesser wattage to blow them.

What is theTransformer rating in a power supply?
a power supply must deliver xxx watts to a load the transformer must match the load capabilities plus its own loss
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.
If an amplifier is AC 220Watt and 12 DC so up to how many watts or ohms speakers you can use on it?
Your question doesn't fully make sense. Let me see if I can answer part of it. If your amp puts out 220 watts, the speakers should be rated for at least 220w, or they may be destroyed if you turn the amp all the way up. Watts are a measurement of power, in the case of speakers they are rated for how much power (watts) they can handle. Ohms is a different thing altogether. Ohms are a measurement of resistance to electrical flow. Amps are usually rated to work with certain impedance level speakers (4 ohm, 8ohm, 16ohm, etc.) the lower the ohms, the harder the amp works. I know it seems backwards but it isn't. each amp is different so you would have to read the amp's spec sheet to see what they reccomend. I have no idea what you are asking for with the "12 DC" thing.
If transmitter power is increased from 200 Watts to 400 Watts how do you convert to Db form?
Decibels (db) is relative power, log base 2, times 3. Increasing power from 200 watts to 400 watts is doubling power, so the decibel change is +3 db.800 watts would be +6 db, 1600 watts would be +9 db, 100 watts would be -3 db, 50 watts would be -6 db, and so on.
If a 13 dB gain antenna has 2 watts of power at the input what is the effective radiated power?
40 watts
What power of amplifier do i need for 6 ohm speakers to connect them to my computer?
Most power amplifiers will handle a load of 6 ohms. The spec you need to look at is the power handling of the speakers. If they are rated for 100 watts program power, then look for an amplifier rated for 100 watts RMS output. Any amplifier can be connected with adapter cables to the typical 1/8" output of your computer.
How many watt amplifier will power two 15 inch speakers?
It depends on the power handling capability of the speakers. Generally, a 500-600 watt amplifier would be sufficient to power two 15-inch speakers that have a power handling capacity of around 250-300 watts each. Make sure to match the amplifier's power output with the speakers' power handling to avoid damaging the speakers.
What is the wattage for jbl model mr902?
The JBL MR902 speakers are designed to handle up to 180 watts of power. This means that they can handle up to 90 watts RMS (continuous power) per speaker. It is important to match the speaker's power handling with the appropriate amplifier power to avoid damaging the speakers.
What is the output power of home theater speakers?
The output power of home theater speakers can vary by a significant amount depending on which speakers are owned. It can range from 30 watts to 150 watts.
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 speaker match to 500 watts amp?
All car speakers will go well with a 500 Watt amp, but for the best effect, get a power subwoofer.
How many watts do factory speakers have in a 2010 corolla?
Speakers are measured in Ohms not Watts. Watts is the amount of power you will be supplying to the speakers. In my 2009 Corolla the speakers can handle at least 400 Watts as this is what my OEM JBL system is pushing.
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.
Does more watts mean better sound on a amp kit if wired to subs?
It is best to always power match an amplifiers wattage to a driver. It is best to have more clean power to a subwoofer, then less to avoid clipping (distortion). If a JL Audio driver calls for 1500 continious watts into 3 OHM, then give it to it, or a little more- never less. Speakers are damaged more by receiving less power then they need. Keep in mind that there IS such a thing as overpowering a driver. That same JL sub would smoke if 3000 watts of pink noise were pumped into it for 48 hours.
How much power do you need to drive the speakers on a Home Theater System?
They often come with 1200 watts,but since the speakers are matched to the rest of your system it's not a problem.They wouldn't sell you components that didn't match up.
Should your speaker watts be more then your amps?
No, the speaker watts should not be more than the amplifier output in terms of power. It is important to match the speaker's power handling capability with the amplifier's output power to avoid damaging the speakers. It's recommended to have an amplifier that can deliver power within the range recommended for the speaker.
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.
