Should be a fairly easy question to answer for people with experience. If a head unit has only 2 RCA outputs (front and rear speakers) @ 2v to connect an amp. You take two 2 to 1 RCA "Y" cables, and plug both rights into one and both lefts into the other Then used a standard car audio RCA wire from the amp the the "y" cable at the head unit what would happen? Would there be any benefit to doing this? Thanks forum.
