First, DISCONNECT NEG BATT CABLE...this prevents you from frying either yourself or your car
This is pretty much how you remove everything

Just be careful pulling the bezel off cuz they can be a tad delicate.
Then when u get your dash kit and your harness make sure you install those correctly.The dash kit is easy as pie to put in. Just follow the directions it comes with. The harness plugs into the factory locations then you match up the colors on the back of the radio to the wires coming from the harness then you install in reverse. Pretty simple!!
Then wiring the subs is pretty simple as well. Just make sure you have a clean ground (most people use their strut tower as a ground point) and when you are running the wires thru the car, always run the Power wire opposite the RCA and the Amp Turn On (small blue) wire to prevent interference. On the pass side under the carpet is a grommet that leads right thru the firewall. This is the most common Power wire pass thru point to get to the battery. Hook the RCA's to the back of the radio as well as the amp turn on. Some radios come with a specific spot for the amp turn on lead but if yours doesnt, i would just hook it to the yellow wire which is the ignition/Acc wire. It comes on any time you put the key in and turn to acc. Then after that turn car on to check to make sure everything works (its a pain in the ass to have everything buttoned back up only to find out something isnt working right...LOL)
