[QUOTE="dB-r, post: 6702704, member: 574699"] NOTE... AC clamping is necessary for finding your impedance, so it is important... Good thing is most DC Clamp meters also do AC... So you don't have to buy two seperate meters, you can use the AC side to get your impedance, and use the DC side to get you more realistic power output numbers... Class D amps are all like 80-85%, I don't care what fluff they feed you... Class AB's are 50-60% at low volume, but can be as high as 80% or so at full volume... weird, I know, nature of the beast...
