Not sure if this has been brought up before but thought I'd give people a little heads up on my interpretation of the impedance switch/selector on a fair few varieties of Receivers and Amplifiers of home theater and why it is a bad idea to use. -->
Oooh this one IS IMPORTANT. At anytime I have just discovered, do NOT set the impedance selector on the back of the amp to 4 Ohms, make sure it is always set as high as it will go (usually 8Ohms), all that switch there is for, is for the receiver and amp company's to cover their ass, and with it turned on you can possibly damage your speakers, with it in the lower position you almost half the power output of the amplifier, and reduces the sound quality incredibly as it just reduces voltage, hence you would then be underpowering your speakers, hence introducing amplifier clipping overall a lot earlier than rather if the impedance switch was in the highest position. Most receivers if not all within the last 20-30 years have overheating protection to stop things from dying anyway, so this impedance switch really serves as a backup system, which lowers the overall fidelity. With the amplifier that I have the clipping protector that I have is turned off, but that option on my amp is for when speakers are overdriven and as my amp is matched power wise (wattage) well just under actually with both large and small speakerd connected, my fidelity of the system is improved with it off, as well as turning off the short detection which could also activate prematurely with driving difficult speakers or when the speakers could blow yet again from being overdriven power wise which they aren't, yet again increasing fidelity, and seeing as how I have a slight low load at a slightly lower wattage rating having lower impedance options could theoretically kill my speakers which have no overheat protection of there own.
Unlike my amp as we have (well I have) seen in the past, my single 2 channel amplifier is $1300 worth of just pure amp, has overheated twice now, shutting it'self off for protection in the process. Having it's remaining 3 protection circuits still active (which are unable to be disabled for good reason), has been far and enough to protect itself, and keep it's intended awesome high quality sound. So in short, disable the impedance switch no matter the speakers you use (set it back to 8Ohms from 4Ohms and keep it at 8Ohms if not done so already).
Loosely what I managed to interpret from this very well described article located here --> http://www.audioholics.com/education/amplifier-technology/impedance-selector-switch-1
