Understanding Amplifier Power Ratings
A watt itself is a unit of energy that can be correctly described as the power used when energy is expended at the rate of one joule per second. A Joule is a quantity of work or heat that is generated equivalent to the force of one Newton moving an object at the point of application, a distance of one meter.
Now this wonderfully concise physical description can be as well applied to the actions of amplifiers upon their loads (speakers) as it can to any other phenomenon. When electrical power generated by the amplifier is applied to a load to do work, (move a cone back and forth) the resulting energy expenditure can be uniformly measured in a standard way, and applied to all other similar situations.
There is only one comparative power designation that is truly helpful, and that is:
which stands for Root Mean Square
, the only reasonably accurate, consistent, comparative measurement of power exchange that should be used for both amplifiers and speakers. RMS is an average of the power transfer between a generator and normative load that is obtained by measuring the AC power with the formula P=EI cosine Ø where cos. Ø is the power factor.
Generally (but not always), RMS is half or less of the value usually attributed to alternative methods such as: Peak power, Max power, IPP - Instantaneous Peak Power, PMPO - Peak Music Power Output, and other measurement methods, that while having a nebulous mathematical consistency, are still little more than schemes to create higher numbers to increase sales. Some manufacturers of low price components have recently taken to promoting power figures of as much as 10 times the RMS specification. Be wary ...very wary!
Many manufacturers provide specifications without mentioning what kind of watts are being measured. Again, this almost always means that those are not RMS watts, and the actual power is half or less (often, much less) than the number indicated.
Where are Watts Found
It is important to remember that amplifiers create an amount of electrical potential that does not become watts untill the energy is converted to another form. This happens in the speaker, where the voice coil consumes watts of electrical energy as it converts it to sound amplitude as measured in decibels.
Multiple power points
Another favorite trick is to just throw out a number for woofers with two voice coils or amplifiers with 2 or 4 channels. This invariably turns out to be the maximum watts for all functions. So:
"300 MAX watts Four Channel Amplifier" really means 150 watts RMS divided into four channels or 37.5 watts RMS per channel. Often it can mean less. Decidedly less impressive, eh? Or, for a woofer, "400 watt dual voice coil woofer" really means 200 watts RMS divided by two coils or 100 watts RMS per coil. This could yield disappointing results. Unfortunately, these descriptions are not always consistent. If they were, it would be easier for consumers to pin them down.
But that's not all! There are plenty more complications where these came from. For instance in amplifiers, there are amps with not only multiple channels, but the capability of being bridged. This means that any two (but only two) channels can be bridged to form an amplifier of approximately double the capacity of a single channel. It does this by taking a mono input signal and dividing it between the positive peaks of the signal and the negative valleys, and amplifying each separately. These separated polarities are then reunited at the amplifier terminals to form a unified signal again for the woofer.
Thus, two 75 watt RMS amplifiers can become a single 150 watt RMS amp. In a four channel bridgeable amplifier, four can be come two, each with twice the power of a single channel.
But look out here! Most amplifiers are of the class AB variety. this means they can be bridged to a 4 ohm load only, yet some brands advertise the total of the 2 ohm load each channel can carry separately. This is very misleading and should not be confused with the amplifiers described in the next paragraph.
Multiple power ratings
While 4 ohm remains the industry standard for many car amps and single coil woofers, capacities are tending downward, mostly because of the increase in the watt numbers attendant to lower impedance carrying ability. At a minimum, better quality units will list "2 ohm Stable" as a feature. Since most speaker loads are highly variable in operation, and will have occasions when operational impedance of a 4 ohm system can go below 2 ohms, it is good to have this capacity so that distortion is reduced at high amplitudes, especially.
Dual voice coil woofers can have coils that are 1, 2, 3, 4, 6, and 8 ohms. This means that such woofers can be configured to operate either singly or separately at the most efficient level. These woofers can be connected in a variety of ways to the multiple impedance amplifiers. Dual voice coils can be connected either in parallel or serial circuits. A woofer with two 4-ohm coils connected serially would produce an 8-ohm total, or in parallel (with both + terminals and both - terminals tied to one set of amplifier terminals) a 2-ohm load. Of course, a single voice coil can be used also, albeit at half the rated power. Check our Impedance Calcultor to get it right.
With two woofers connected in a serial circuit, two 2-ohm woofers can present a 4 ohm load, or two 1 ohm woofers can present a 2 ohm load.
The best common configuration is to use two dual voice coil woofers with 4 ohm coils. All four coils in parallel will make a highly efficient 1 ohm load, with power handling equal to the total RMS of both woofers.
But in all cases, the idea is to match both the impedance and the output power capacity of both the amp and woofer units. A good relationship is for the Amplifier to supply between 10 to 40 percent more power to the woofer than the woofer's nominal RMS watt handling rating. Thus, a 200 watt woofer should optimally have a 225 to 280 watt amplifier channel connected to it.
