Again, i have zero desire to and i am not going to do anthing other than replace the 6x9's! The stereo is 100% stock and the ONLY thing i'm not happy about is the way the rear 6x9's distort in the low end when cranked up fairly high. Other than that i'm totally happy with it and i don't want or need any amps or front speakers. The rears distortion isn't tha amp either..........it's the speaker. So all i want is a 6x9 that doesn't distort, tho a set of 6x9 subs may be even better, hence the original question.
