What Are (Ohms) Specs Of the Stereo Head unit on my 2011 Kia Optima LX?

I am getting a new amp and subs for this car but wanted to keep my head unit so that i can keep my steering wheel controls and overall stock look for the car. does anyone know if my subs and amp will sound bad without getting a new headunit? what is the specs on the cars system?

ps. Without the upgraded sound package on car.

THANK YOU!

Update:

my car doesnt have rear speakers up in the trunk area. they put them in the rear passenger side doors only.. :/ which is odd. But thanks for the info!

    stereo does squat for an amp unless it has sub preamp outputs in which case u can control the sub volume.

    I have owned only hondas/acuras and never replace the factory stereo (alpine makes them for hondas)

    specs? idk. jump on the kia website to see the rms output. not sure what u need that info for. the signal sent to the amp is preamp, meaning a simple clean signal (unamplified) that the amp in turn amplifies for teh subs/speakers

    all u need is a line out converter to tap into the rear speaker wires and send a low level signal to the amp.

    like this:

    then run rca wires to the amp.
