It depends on the power rating of the speakers. There is insufficient information in the question to properly answer it. Please restate the question.
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.
RMS is basically the amount of watts that the stereo can continuously dish out and the peak is like the most watts it can give out but only in bursts. And the the amount of channels is how many speakers it can give power too. So basically you can continuously give out 20 watts to each speaker if you have four hooked up to the thing.
25 to 35 watts
Most factory speakers are any any where from 10 - 25 watts RMS. I wouldn't put factory speakers on an amp unless you want to blow them.
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.
Either too hot of an environment or too many watts going to them.
64 watts = 18.1 decibels. If by 'set' you mean you have two 64 watt speakers then they will create 36.2 decibels.
Usually theyre pretty weak, as low as 6W, 10W to 20W for factory.
they use around about 55 watts for each headlight.
led tvs 55" or bigger especially manufactured after 2009 use around 350-370 watts plus 15w a piece on the speakers generally around 400 watts pulling 3.5 amps
Xenyx 802 is not a powered mixer, you need a separate amplifier with it to drive the speakers
50 watts is a good amplifier size for use in the house. For other applications speakers usually have a power rating.
