You shouldn't cause any damage as long as you don't try and crank the bass. As long as you adjust the gains properly, and don't get any distortion then you should be okay. But as soon as you hear distortion, turn the gains down or adjust your bass level. Even at low wattage distortion can cause problems!

Not having the gains properly set can definitely cause distortion at low power.  Also, any amplifier will eventually go into clipping and thus have a distorted output, if you try and play it louder than it is really capable of playing.

How do you set the gains properly?

Start with the gains turned all the way down (usually counter-clockwise). Make sure the headunit bass controls are set to 0 (let the amp do the work!) Put in a CD with a good bass track and turn the headunit volume apx. 3/4 of the way up. Slowly turn the gains up (clockwise) until you start to hear distortion in the subs. Then turn the gains back down a fraction of a turn, just enough to get rid if the distortion, and you're set.

Can you tell me exactly what distortion sounds like?  Will it be obvious noise?

Yes, it will be very obvious. Having no distortion is clean and clear sound (very distinctive like the difference between a modulated FM signal picking up a weak radio station vs. listening to a CD). Distortion will cause the sound to waiver (could sound crackly). Since your temporary amp is no where near the RMS range of the RFR3112, you may be able to turn the gains all the way up without hearing any distortion at all. So don't be worried if you can't tell any difference unless the sound is not clean to start with.
