Watts! How Many Do I Need?

Over the years in the audio industry there is no question asked more then "How many watts is this" it could refer to either an amplifier or a speaker but in the end it really does not matter. People are sold on numbers and comparing statistics between devices and watts appears to be an excellent means of comparison...unfortunately it is not.

All manufactures lie about the statistics of their products and all of them in fine print say "design and specification are subject to change without notice". Speakers sound best with the most powerful amp you can afford, you will never destroy speakers by overpowering them, you destroy speakers by over driving a weak amplifier. Spend similar amounts on both your speakers and your amp. In the end you get what you pay for, focus on the sound and not the numbers!

Will a Pyle PT530A 350watt receiver work with a pair of 4ohm 200wattRMS per speaker


Yes they will, but alway be careful with audio gear.
There are 30 watt speakers that can handle peaks of 500 watts for a short time. There are also 500 watt speakers I can "kill" with a peak less than 500 watt.
Most amplifier manufactures like to boost about the power an amplifier can deliver and their speakers can handle. But as long as they don't tell how long the speaker can handle the power and at what frequencies the value does not say anything.
Whit high power amplifiers, never switch over while the volume if at maximum.
You know what I mean. I can't hear my CD player. first turn the volume to the max and then press the CD button, and the speakers will explode. Always when you preaa any button on the pre amp juts lower de volume first and you won't destroy your speakers.
My old Kef Concerto's are almost 40 years of age. 30 watt and are running on a 500 watt Yamaha amplifier for years now. And believe me my chidden know how to punish a speaker. Never any problem, nr with the speakers, nor with the amplifiers.

Which speakers (Front/Rear) to buy that match Kenwood KAC-M846 4/3/2 Channel Amplifier.


I don,t no where you are reading thease articles from,I installed car audio equipment for over 40 years, Untill i retired a couple of months ago, Who ever is writeing those sort of articles does not have the slightest clue what they are talking about, It is the opposite way around, It is allway better for yor (Speakers) To handle more power then what your amp puts out, Then you will not blow the spaekers, It is best to get speakers at least 20 watts more then what your amps maximuin (RMS) Watts are, Hope this helps you out, (PS) 50 watts (RMS) Is what most people go for, It is in no means (Under) Powered.

how do you bridge the jl audio 450/4


Nice amplifier. However it is best suited for speakers and not for sub woofers. Connect the plus (+) from speaker output 1 and the minus (-) from speaker output 2. Connect the plus (+) from speaker output 3 and the minus (-) from speaker output 4. Now the amplifier is in bridge mode, which will give you 300 WATT RMS at 4 OHM load. If you are bridging the amplifier to run sub woofers then do not forget to set the X- Over to LPF on the channels that you are planning to bridge. Whatever you do, make sure that the load you are asking the amplifier to play is no lower than 4 OHM. Playing this amplifier in bridged mode lower than 4 OHM is a recipe for trouble.

how can i get more power through 8 ohm speakers?


In addition to the impedance rating of a speaker, there is also a wattage rating. Ideally, power output of the amplifier should not exceed the power handling rating of the speakers. The input impedance of the speakers should match the amplifier output impedance for maximum power transfer (Rin = Rout where R is resistance in Ohms). Supplying more power or wattage to the speaker than it can handle will result in distortion, and if the output of the amp is high enough and present long enough, it will damage the voice coil of the speaker. Make sure that when comparing wattage ratings, you are comparing the same rating between amps & speakers. Watts can be expressed three different ways: "Peak", "Peak to Peak" and the industry standard "RMS". The relationship is such: an industry standard value of "70 Watts RMS" (70W RMS) equals "100 Watts Peak" (100W P) *and* also is the same as "200 Watts Peak to Peak" (200W P-P). Furthermore, there is no such thing as 200W "Music Power" (but is often expressed this way to inflate the RMS wattage rating (and usually is close to the P-P rating). A speaker is an electrical device, so most the things that happen to electrical devices when over powered can happen to speakers and amplifiers, too.

Increasing the signal source level (input signal to the amp via volume control) in an attempt to get more audio power to the speaker can overdrive the amplifier - resulting in "clipping". This is plainly heard as "muddied" sound. The otherwise loud, crisp, clean passages in music end up sounding garbled and unpleasant when an amplifier is over driven in this way. This can damage both the amp and the speaker.

Cheap amps with higher THD (total harmonic distortion) ratings sound worse than their counterparts with a lower THD rating - when all other variables are the same. You'll pay extra for lower THD values.

You might be able to make a speaker seem louder by positioning the speakers against a wall, on the floor, etc. Experiment; as it can make a significant difference in sound levels and low frequency bass sounds.

I hope this was helpful!
