Answer
Hi Jordan,

The factory radio does not have RCA outputs for connecting an amplifier, so you'll need either an amplifier with high-level (also called speaker-level) inputs, or you'll need a device called a line output converter.  In either case, you'll need to tap into the factory speaker wiring to get an audio signal for the amp.  

The most convenient place to find the speaker wires is the rear of the factory radio.  The speaker wire colors should be as follows:

Front left +  Blue/white
Front left -  Blue/red
Front right +  White/black
Front right -  Blue/black

Rear left +  Light blue
Rear left -  Black/yellow
Rear right +  Orange/blue
Rear right -  Red/blue

Hope this helps!
