Hello peeps great forum - just bought my Kicker sub and am in the middle of the install - I have a 2019 non-bose Silverado. I have located the 28 pin connector and I get the splicing bit about connecting the brown and green wires.... the part Im not sure of is the OTHER end of the harness near where it connects to the sub and amp ALSO has a 2-wire connector with brown and green wires. Where does this end plug into? I only see the amp and sub connection. Is it optional for some sort of other external amp? If so that doesn't seem to make sense as you are literally connecting the other end of the brown and green wires to that 28-pin connector up by the kick panel.
Also for what its worth I found it much simpler to route the wire harness down the passenger side of the truck and in behind the rear seats. (instead of going under the passenger seat and over to the drivers seat under the carpet as the manual says)
Thanks in advance.
