The front doors can hold 6.5" speaker. The Front dash has 3.5" speakers, but it is a tweeter in there. I replace my doors and dash with a 6.5" comp. set which is 6.5" Midbass woofer and a 1" dome tweeter. I cut a piece of wood to fit the area so I can mount my tweeter. I had to cut nothing all looks factory. You do have to buy a mounting plate or make one for the doors. It is an over-sized 6.5" speaker even a 7" will fit.

For the rear it is a 5x7. There is now conversion unless you feel like making something. I am using 5x7 coax Alpine.

The stock radio does not put out much power maybe 7 to 8 watts per ch. I changed my radio before I changed the speakers and it made a huge difference right away. You don't need an amp unless you are going to hook up a sub and have a major system. I suggest get a good Alpine, Pioneer, Kenwood, or even Sony Radio and replacement speakers and you should OK unless you are looking for something bigger. YOu can always ad to this later also.
