Take this for what it is (my opinion) but dont skimp on the head unit and this would be my first choice. Get the unit you will be happy with after you decide what it is you want the HU to be able to do (i.e. GPS, DVD, Ipod) Personally I love Pioneer, but defiantely spend the money on the Head Unit, it is the item that drives the rest of the system. Next I would Get quality interior speakers cause the good head unit will be good until you decide to put an amp to them. Then its a matter of deciding what type of bass, mid range or hi-freq sound you are looking for. A real good quality 5 channel amp, and a real good 10" - 12" would be good. Not a lot of space taken and you can have a good all round sound with the ability to upgrade your bass level in future if needed and not loose what you spent on the HU or interiors and amp. Good luck.
