yes that is correct. you will have to locate the speaker wires for each speaker on the output of the amp, and that will take a while. You might find a wiring diagram for the RF system on the forum somewhere, I don't remember seeing one though. you might just want to use the wiring harness that comes with the radio, rather than the crutchfield supplied one. The only wire that will be helpful from the harness they gave you will be the red, 12V switched wire. Everything else you will have to wire yourself. Just remember you will have to connect the yellow to the battery via the 10Guage wire.
