If you do it yourself make Mark D help you (I'm the guy that helped Mark install his). It really isn't that hard if you know anything about installing after-market stereos. You need an amp if you don't have one already. If you buy it from Crutchfield they will send you their install sheets which tell you how to take your dash apart and what wire is what. If you already have an after-market stereo installed it is really simple.
