[QUOTE="keep_hope_alive, post: 7626427, member: 576029"] don't take this as an attack. i'm not mad, i just need to clarify a few things. you are misunderstanding me, or how this works. i didn't say anything about current. we're talking about voltage, specifically line level voltage being fed into car audio amplifiers using standard source components. when the amp inputs sum the left and right channel - you get a 3dB gain (i.e. 2x the voltage) on the input signal - for signals that are equal left and right. if a signal is in one channel only, then obviously there is no gain. a voltage gain on the input = increased voltage on the output = increased output power (assuming all else is constant). i do agree that gains would be adjusted if you change from 1 input to 2 inputs. there is no "strain" on input components - op amps and transistors don't experience "strain" from an input signal whatsoever. they'll just clip if the output is greater than the supply voltage - but the circuit is designed such that no amount of clipping will hurt the components - square waves are acceptable signals too. EE's don't need analogies to understand electronics. the bass guitar, floor toms, piano, etc. can be shifted in the soundstage depending on the recording engineer - it is album dependent and none of us will ever know how every song ever made is mixed. so we design systems that are universal and provide both channels to the system components.
