2009 focus stereo quality

hi there, we just picked up a 2009 base focus. the gf is not impressed with the quality of the sound quality of the oem stereo. so I'm wondering if the head unit is crap or if the speakers are the main culprit?

I'm asking because I swapped out a cheap pioneer aftermarket with a stock stereo in my Pontiac vibe and man was it way better. I hoping its the speakers!
