AND WHAT IS PEAK POWER ?

WHAT SHOULD I LOOK FOR WHEN I BUY SPEAKERS RMS OR PEAK?

COZ I JUST GOT KINGWOODS 6.5 600 WATT PEAK

RMS - continuous power

Peak - max power an amp can produce under extreme circumstances

Look at RMS ONLY

Ok?

You shouldnt have bought the "Kingwoods"

You cant get 600 watts out of those speakers. power comes from amps. BTW I doubt the kingwoods would handle more than about 80 watts for the pair

That is why we search

Hope that helps

P.S. KILL THE CAPS LOCK

RMS is a thermal rating of how much heat (or power) a speaker can take continously like SS said before it is damaged.

Peak power is a "lightning strike", a rating of how much power a speaker can take for a brief surge. Its useless to look at, and for the most part its a marketing scheme.

You should look at RMS, and you need to match the speakers RMS. Not completely, as a speaker does not need 100% of its RMS to achieve full output. I.e. a 100wrms speaker might perform the same given 75wrms vs. 100wrms.

Do you mean you got Kenwood speakers? They are not very good speakers. I would try to bring them back and let us help an guide you here to enlightenment.

i got the 6.5 inch ones but u guys know more so its no where close to getting 600 watts even wid amp ?

but they sound better then my factory ones for 30$ i dont think it was a that bad of a deal ?

well as u all know i know nothing abt these things this is the 1st time i actually bought speakers

so tell me ill spend abt 1000$ on my car audio

but i want everything best speakers amp subs hu all those things i think 1000$ will be enough for this ?

btw is pioneer the new 5way 460 watts anygood ?

thanks

It doesn't work that way. In my opinion, you need to have a goal for the system. Where it is bass, sound quality or just an upgrade over stock. Atleast you have a budget. Explain more of your plans and we will be more able to assist. Lastly, if you are content with the Kingwood, then don't let us stop you. Many on the forum dislike the kappas, but I love em.

best...such a subjective word. A componet system is better, but quite a bit more costly. However, I think only a few people make 6x9 component systems. Personally, I have found anything above coaxials to be less than quality sound.

If you want an inexpensive sub, that is quite musical and plenty loud inside the car, but not outside, I HIGHLY recomend the Infinity Basslink. It's a 10" sub, with a 10" passive radiator, and a 200w Class D amp in one housing. It will work from RCA inputs or speaker-level inputs, and has a remote knob to turn the sub up or down as you wish. I think mine sounds fantastic, you won't win any trophys with one, but it sounds badazz.

These seem to be around $200, for a sub, enclosure and amp that sounds like it does while using a minimum of space.... pretty sweet IMHO

The RMS power of a speaker is how much power it can handle, not how much power you'll get out of your headunit/amplifier.

Also, if that "50w x 4" is from your headunit....you won't get anywhere near that much out of it. Most put out in the vicinity of 10w - 15w RMS. So, those speakers would get around 10-15w each.

newdavid
09-16-2005, 12:22 PM
so how can i get all that 80 rms out of that speaker ? or atleast 50 rms ?

have to connect it to high power amp ?

if those are 800 watt speakers

i need like 2 channel 800 watt amp ? 2 x 400 watt ?

all i am trying to do is if i pay for 400 peak power or 50 watt rms

i somehow want to get atleast 300 peak and 30-40 watt rms out of it

Poor dude --

Anywho... how it should be done...

The head unit decodes whatever music you happen to want to play... it turns it into voltage coming out of the line out jacks in the back... The low level voltage gets to an external amplifier -- it uses the crazy magic inside of it to create a higher voltage replica of the original low level source by using the car's DC power supply...

The signal is than run to your speakers... depending on how much voltage and current is coming out of the amp -- depends on how much power is being turned into sound (mostly turned into heat) -- at some point if the speakers eat too much heat they blow up...

The rating is simply... when they blow up... --- Now these ratings aren't very standard so you should take them worth a grain of salt and you have to analyze... hey what will this really take??? The ability to do that though comes with checking out bcae1.com -- reading the forums -- and thinking about things...

I mean I could help ya put a system together for X dollars but -- you would still end up being a fish out of the water when you went to install it... Research is your friend. I suggest doing a week or 2 of reading up on things and then start work on assembling a system...

Feel free to present questions if you read something and are having problems understanding it :)

You are closer than you were before...

There would be no reason to have 4 6x9s. But, perhaps 2 rear 6x9s and the 5 1/4s from pioneer you mentioned earlier. I wouldn't go this route, but to each thier own.

You don't "get from" speakers. The amplifier pushes, in this case, 60w rms to the speakers. Speakers do not create power, more like an output of power. Just like a lightbulb. It doesn't make power but uses it to do something. A speaker makes noise, a lightbulb makes light.

The CEA-2006 mention on there is an industry attempt to standardize how speakers, amps, ect. are rated.

What amp is that by the way.

the pioneer 6x9 can handle 80 watt rms

this amp will produce 60 watt rms of sound in each rite ? which means i will be using almost all the power my speakers can handle ?

and if i only connect 2 4ohms 6x9 will it give 120watt rms each ?

IM FINALLY GETTING THINGS MAN THANK YOU :)

and is 80watt rms from each speaker is that gonna be load ?

150 watts RMS x 1 bridged output (rear channels only) at 4 ohms (4-ohm stable in bridged mode)

does this mean if i connect 1 speaker on rear channel i will get 150 watt rms ? or 150 each on rear channels ?

and it says 600watt 2/4 channel amp ...... the rms is only 300.......

whats this :(

Flipx99
09-16-2005, 05:08 PM
Stated RMS is usually 1/2 max. Assuming load = loud, it won't break any records but it will be good enough. About what I was working with when I first started. Not to say that I am a pro now.

I would explain it but it's easier if you have diagrams. Search for bridging amps.

newdavid
09-16-2005, 05:17 PM
so this amp has 600 watts max PEAK POWER and 300 watts RMS power ?

and when i hook 4 4ohms speakers to this i will get 150 peak and 60 rms each ?

It is not as simple as that as different manufacturers have different ratings. Ever see one of those pyramid amps that have 2000 watts for $200 or something. They don't push 2k watts.

75W x 4 RMS into 2 ohms, 20Hz - 20kHz @ 0.1% THD
60W x 4 RMS into 4 ohms, 20Hz-20kHz @ 0.08% THD
60W x 2 + 150W x 1 RMS into 4 ohms, 20Hz-20kHz @ 0.1% THD

i must chime in... there is no way in hell that you are going to listen to music at such high volumes that 75 watts or 60 watts is required for the speaker. i have a 50 watts running to my speakers and i dont even turn my headunit that high... other ppl have measured and say their speakers usually dont get more than 20-30 watts at high volumes.

so dont worry about getting the biggest, baddest amp in terms of power. get one that is known for quality sound and puts out SUFFICIENT power. (that means, stay away from the sony)

Have you ever wondered how that pair of speakers they are selling at the discount store for $10 can put out 120 watts of power? Well, depending on your definition of output power...they can...and it has fooled many people! I know people have told me that their home stereo unit has 2600 watts of power output...even though it is connected to a standard 120-volt power supply that is only allowed to draw 2000 watts before tripping the circuit breakers!

The answer to this issue lies in how they measure the output power of the device. Usually if you look at these huge numbers, you will see the letters "PMPO" underneath. PMPO stands for "Peak Music Power Output" or "Peak Momentary Power Output". Notice the word peak. The vendor of the product calculates PMPO based on the maximum power output of the device under perfect conditions and 100% efficiency. These conditions are impossible to obtain, and no device can sustain the PMPO power for any significant length of time without being ruined. The PMPO power relies on the fact that amplifiers can provide short bursts of very high power. Over time, these short bursts when averaged with the lower output powers, gives the real value.

The Real Power
Vendors use PMPO power to hide underpowered power supplies and amplifiers. When you see something with a PMPO measurement on it, turn it around and look at the specifications. Often, the input power from the AC mains is 5 or more times LESS than that of the PMPO power. You also may see a more accurate measurement, called RMS (Root Means Square) power and DIN power. These types of measurements average output over time, creating a much more reasonable reading. Don't be fooled by cheap products which appear to put out big power.



So, how do you find the RMS Power from the PMPO Power?
I have been asked this, and there is no single answer or mathematical formula to convert these values. The peak output of the amplifier is going to differ based upon the amplifier's design, and the type of sound that is being amplified. Often each electronics manufacturer will create their own proprietary formula for figuring PMPO power. Usually, the PMPO power is about five to ten times higher than the RMS Power.

There is NO mathematical formula that will convert PMPO to RMS values or vice-versa

NOW I GOT IT
