Peace,
The front speakers are located under the front dash panel. To gain access to the speakers you will need to take the side panels and the dash out, this is fairly easy to do. First grab the side panels near the top and pull, there are keepers holding it in and no tools are needed. Once you have one side removed go to the other side and pull the panel off. Next will be the dash and it is also held on with keeper clips. Start in the middle and pop the panel loose. At this point you should have the side panels and the dash panel removed. The speakers are held in place with Phillips screws.
