Hi all, when swapping out a headunit in a C6 with no Bose, do you connect the headunit’s RCA preoutputs to the RCA plugs on the PAC wiring harness or do you cut the RCA plugs on the PAC and wire them into the headunit’s amped speaker outputs?

If your interface adapter has RCA's, plug them directly in to the new radio
