Now with the K, s my personal fav. I think theyre rated around 115watts at 8ohms. D, s the same rating. If ure bridging your Mac I think ure model will send 240 watts out the right mono side. That would be ideal for one E120.
Post ure jbl starting LETTER.
Also I think someone mentioned bridging their mc2300 n thinking their sending 300watts. If 2300 was bridged it, s sending 600watts out right channel.
If jerry used 3 - 300 watt speakers he would have a total of 900 watts available to him. Throw in a fourth and he would be sitting at 1200 watts. He would NEVER blow a speaker even if he did bridge the Mc2300 for 600-700 watts output. He would NEVER get anywhere close to actually breaking those speakers up. The truth is that both the E120 and K120 have 2 wattage ratings and only one of them is correct for the way he used them. The Continuous Sine Wave rating for an E120 is 150 watts and a K120 is 100 watts.
As for bridging, the amp has 2 inputs and 2 outputs, one set for each side of the amp making up two channel for stereo operation. Bridging the amp combines both outputs and switches to only one input since it has now created only one output. So when bridging a mac you are using the mac's right input but both outputs creating one channel or Mono operation. In stereo operation you actually have 2 mono channels.
