There are no RCA outputs on the factory head unit, and if you plan on running subwoofers it's a good idea to upgrade to a better one. However, if you plan to keep the stock system in place and just want to add the subs, you can tap into the speaker wires and either use an amplifier that has high level inputs, or use a line level converter and RCA plugs. Upgrading the factory head unit is very simple and you can buy great aftermarket head units for under $200 that'll provide better sound, more power and more features than the stock one.
