An RF modulator is an entirely different animal.  You will need to purchase 2 Line Out Converters.

The above wires are located behind the radio.

"where do I get the RCA output from an RF mod"??  What are you trying to do?  What RF modulator do you have that has no RCA outputs?  And please tell me you are not really an installer who doesn't understand how to hook up an LOC...

Excuse me?  No, I'm actually trying to understand what you are trying to do.  Can you explain your plans?  Thanks.

First of all please check all attitudes at the door. Second, you can not use an RF modulator as a line output converter from a headunit to an amplifier. You need to use an LOC (line output converter). You can use the front speaker or rear speaker outputs from the factory radio or both depending on your application, and in this case you would use both. Purchase 2 two channel LOC's from your local stereo shop or place of preference, then read the instructions that come with them. I_am_an_idiot provided you with the wiring information you'll need. If you're still lost, feel free to post more questions in this thread.

if your keeping the factory head unit the easiest way is to use a male and female version of the wiring harness for your car (Metra 70-1721 and 71-1721) and 2 line out converters aka stepdowns. take the 2 harnesses and connect everything up to each other but the 8 speaker wires. connect the LOCS to the radio side speaker wires and then connect some speaker wire to the car side harness and run them to your amp. that will give you RCA output from the radio and connection  from your amp to the speakers
