they sucks!! but thats not why you are buyin the car, right?!
i actually brought 3 CD for all the car that i test drove before buying the wrx... but just to know, didnt influance my decision heheThe stock unit is pretty bad, The Rockford system in my old Nissan was much better... But as mentioned above, I sure as hell didn't even think so much as to turn the radio on during the test drive. Plus it's easily replaced
I personally think the stock stereo is horrible.. coming from the Honda Civic, i found the subaru stereo soft in the low frequency, making conversations on the radio hard to hear while music sounding hollow.
