Stock amp to aftermarket question
 

Have been doing a LOT of reading here. Great info, thanks to all that have posted. I have noticed multiple LOC's used to provide a full range signal to aftermarket amps. Why not simply twist the three front left + together and the three front left - together? Wouldn't those three together act as one channel into a line out converter? I am sure there is some reason this cannot be done, but none that I can think of...
