I believe some of the early model FR-S's had head units with RCA outputs, but none of them have had them since.

Navigate your way around there for a while.
I'll tell you that there is a factory amplifier in the trunk underneath the floorboard covering the spare tire that powers the two door speakers that act as subwoofers. The dash speakers are sent a full-range signal and that same signal is sent to the amp in back to be amplified for the door speakers. The amplifier has an internal low-pass filter and no gain control, so integrating it into the system can be a hassle if you ever want to replace the head unit with one that provides RCA outputs.
One other note, some of those amplifiers were unplugged depending on which head unit you have and the dealers inadvertently forgot to install the bypass harness to allow the door speakers to operate. Make sure your door speakers work as a couple of people here had to fix that to improve the sound quality.
