How Much Power for My Speakers

It seems like one of the most frequent questions asked in Pro Audio forums and in music stores is “how big of an amp should I be using for my speakers?” It also seems to have the biggest number of confusing answers…1X–1.5x - 2X RMS?, program?, peak?…augggh!
Biamplification vs. Bridging Power Amplifiers

When seeking more output from a sound system, it is common to bridge the power amplifier to increase the power available and generate more output from the system. In some cases, this is the best thing to do, especially if it is a subwoofer being used with a medium to low output power amp.Bridging the amp will give the usual 6 dB more power output, or 4 times the single channel power output into the same load impedance.
Class Act: The Pros and Cons of Amplifier Design

Many manufacturers would like you to believe that there is only one "best" way to design a power amp. These companies usually make only one type of amplifier. Perhaps they believe their own hype, or more likely, they are limited to a single in-house technology or by a specific target market. In the course of designing power amplifiers for the different markets we serve, Peavey has developed products using radically different technologies. I will attempt to give an overview with specific pros and cons of the different approaches.

Over the last several years we've seen a number of power amp ads purporting to educate the market about heat sink technology. More often than not, the chosen approach is neither novel nor superior. The advertisement is more creative than the design being pitched. The following description of Peavey's new heat sink approach will describe a real advance on the state of the art.
Power Amplifiers in Bridge Mode

The maximum positive- and negative-voltage capability of a power amp is limited by the power supply's limits, i.e., its voltage rails. The amplifier can produce so many volts positive and negative at its output. The audio signal essentially swings between the positive and negative supplies within the power amplifier.
