Heres the thing, I want to put in some subs but im audio illiterate. I have the 07 CC with the 6 disc cd changer. I really like the stock stereo, is it possible to have a good sounding system without putting in an aftermarket head unit. I think i wanna run 2 10's. I want to have a good sounding system without spending a fortune. I listen to mainly rock and alternative (disturbed, shinedown, stone sour, slipknot, etc.) What do you guys recommend I do?
