How many watts is a good speaker?
HelloOf course, no one makes a 32-watt amp, but a 40- or 50-watt receiver or amplifier should do fine. If the amp or receiver you want puts out, say, 100 watts, don't worry about it. Remember, at average listening levels with typical speakers, any amp is putting out only about 1 watt, anyway.Motivational Speaker indian
If my car stereo says 22 Watts RMS and 50 Watt Peak power, what size amp should I get?
The back 6x9's say 110 RMS and 450 Peak Power, But the 5 1/2 inch door speakers say 35 RMS and 160W Peak power(they are all 4 ohms). They are Kenwood. The lady at the store said to find a 50 Watt X 4 at 4 ohms amplifier. Wouldn't sending 50 watts RMS blow the door speakers? Is there a way to have the amp send more power to the back and less to the front speakers? Also the car stereo has a built in amp already. Will a new amp be added to the amp already in the deck. Should that be considered? Or will it bypass the deck amp. I only found Alpine having those specs. And a few rare older Kenwood amps. I want to thump so tell me my best and most practical options. The deck has 3 sets of RCA preamp outputs (What is a preamp????), what is a bridge or crossover?? p.s. So far I'm really disappointed at the sound.
If I have two 400 watt RMS subwoofers what size amp do I need? How can you tell?
Probably 800 watts at half the rated ohms of one speaker. Your amp must be able to push 800 watts at, say, 2 ohms if these are 4 ohm speakers or 800 watts at 4 ohms if these are 8 ohm speakers.It will say on the speakers what the impedance in ohms is.Get an amp that is specified with 800 watts or over, at an ohm rating that is SAME or UNDER…half the ohm rating of one of those speakers.That's the answer here's a short ramble:Almost inevitably you will be running the two speakers in parallel. Whether you have two outputs on your power amplifier; or if you go into one speaker then go out from that speaker to the next; the connection you don't see inside the speaker with in and out or inside the amp is a parallel connection. Parallel connections divide the impedance (ohms.) It takes a bigger amp to handle lower impedance, because lower impedance is lower AC resistance. Lower resistance means more amps flowing for the same output voltage. More amps requires a beefier output section. The actual equation for total speaker ohms of speakers wired in parallel is:Total ohms = 1/((1/ohms#1)+(1/ohms#2))…If you put in a third speaker there would be another similar term in the denominator, (1/ohms of speaker #3). More speakers, lower ohms…The amp will say what the watts and ohms are on the back, or at least in the manual it will tell you what it can handle. Be at or below the ohms, and above the watts.
How many watts can a car alternator make?
Most alternators I see these days range from 80A to 140A output as standard equipment. V x A = W, so using the standard 13.8V, we have anywhere from 1104W to 1932W. There are special alternators people use for specific purposes that can produce quite a bit more than that too.
What is the difference between 4 ohm and 8 ohm car speakers?
Two things... Most amplifiers give only 2db higher sound volume at 4 ohm compared with 8 ohm and a perfect amplifier (which normally are incredible expensive) give just 3db higher... And 3db is actually the minimum sound volume difference you easy can hear with music, when you adjust the volume!And most SIMPLE amplifiers / car stereos demand 4 ohm or higher... And even when an amplifier work with 4 ohm instead of 8 ohm speakers, are they then like a car engine that run almost too fast and some get over heated, so they shut down temporarily or simply melt down... Remember also that a 4 ohm speaker often goes down to 2-3 ohms when they play music... And when you use 4 speakers, will normally 8 ohm become 4 ohm for the amplifier and most amplifiers demand minimum 8 ohm speakers IF you connect four speakers, which normally is written on the back... So you better buy 6 to 8 ohm speakers!And if you want to play loud, remember that you can easy find fine speakers that are 6 to 10db more sensitive, than ordinary 88db/w/m speakers and plus 10db sound actually twice as loud!
What is the difference between watts and rms?
Amplifiers are limited in the electrical energy they can deliver, while loudspeakers are limited in the electrical energy they can convert to sound energy without distorting the audio signal or being damaged by heat. These power ratings are important.Amplifiers are valued in part by their power output capacity. loudspeakers, are valued by their thermal and a mechanical aspect to maximum power handling.RMS W- the maximum amount of power an electronic component can possibly handle continuously without damage.Peak power W- the maximum amount of power an electronic component can possibly handle for an instant without damage.Continuous average power is derived from the root mean square (RMS) of the AC voltage or current, often incorrectly referred to as "RMS power", "RMS watts", or "watts RMS".The correct term is "continuous average power", which is proportional to the RMS voltage, and specified by the FTC.In its 1974 Amplifier Rule meant to combat the unrealistic power claims made by many hi-fi amplifier manufacturers, the Federal Trade Commission prescribed continuous power measurements performed with sine wave signals on advertising and specification citations for amplifiers sold in the US. Typically, an amplifier's power specifications are calculated by measuring its RMS output voltage, with a continuous sine wave signal, at the onset of clipping.Continuous power measurements do not actually describe the highly varied signals found in audio equipment but are widely regarded as a reasonable way of describing an amplifier's maximum output capability. Most amplifiers are capable of higher power if driven further into clipping, so the continuous power output rating cited for an amplifier should be understood to be the maximum power (at or below a particular acceptable amount of harmonic distortion) in the frequency band of interest. For audio equipment, this is nearly always the nominal frequency range of human hearing, 20 Hz to 20 kHz.In loudspeakers, thermal capacities of the voice coils and magnet structures largely determine continuous power handling ratings. However, at the lower end of a loudspeaker's usable frequency range, its power handling might necessarily be derated because of mechanical excursion limits. Source: Audio power
