Hi all,

I'm looking to upgrade my amp and got the labels for all the wires that go into the stock am on a 2003 CL-S. The problem I see is the list does not show any input wires? It shows all the output wires to the speakers, the 12v and ground, illum, dimmer and antenna, but no inputs. I know it does not have RCA's, so how does the signal get to the amp? Anyone have any info on this? Thanks.
