Hey! So I'm totally new to all of this, but I just got a new (used) 2008 xB from my parents and have already decided that I don't like the current sound system. It has the stock "Premium" sound system, and although it sounds good for the most part I notice that anything below the mid range is pretty much non-existant. Also I really despise pretty much everything about the head unit. I have a friend with a Honda CRV who had a similar sounding stock system, and he added two 10" subs to it to make it sound better. I did a bit of research with my friend, and basically the additions we came up with would be: two 10" Kicker CompVR 2 OHM subs (He has a lower end version), a JL Audio JX1000/1D amplifier, and a Kenwood DDX419 head unit (at least partly for the back up camera option). If anybody has any suggestions, or comments that would be great! Also I'm not sure what I would want to replace the door speakers with, if anything so if you have ideas for that it would be greatly appreciated. Other than the stereo the car is great!
