Hey all. Im seeking some assistance in connecting my original Delco AM/FM radio in my 75 C20 to an Amp.
Specs are as follows
Vehicle: 1975 Chevrolet C20
Radio: Delco AM/FM
Amp: Infinity Kappa K4
The amp has has RCA Input ports, LF, RF, LR, RR. It comes with Speaker wire to RCA adapters for just this type of connection.

The AM/FM features the following speaker outputs.

According to this diagram they should correspond with these.

My truck only had the Single speaker in the dash, but the radio output has the provisions for the connections labeled H,J,K on the diagram, I just have to add wire.
When I bought it, the truck had two house type speakers (like you'd see on a cheap boombox) wired behind the seat to the connector shown above. (labeled ABCD)
The amp is powering 2 6x9's and 2 3.5"s now, and is bluetooth connected, but I still want to be able to use the stock radio.
My question is, quite simply, which wires to connect, in what order, to which input on the amp. Thank you!
