Further, If the impedance load is the same, and the same power is attained, then voltage is the same and current is the same. A non-bridged 2 ch making the same power as a bridged 4ch into the same load will draw the same current as the same voltage. Now, the efficiency is a different story, but the amps are different so no direct comparison is reasonable and it depends on the amps used. THD is another concern, but you generally have more available power when bridged so you are operating lower on the exponential THD curve. Finally, you have more options with 4 channel amps, including active or bi-amp. [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] [/QUOTE]
