For right now I will just replace the front speakers. I am going to buy the Pioneer TS-A6870R 6x8 from Walmart for like $58 and try to install them. If they don't fit, I will return them. From doing some research on this site it looks like the Pioneer TS-A6870R 6x8 will fit. During the installation I am going to remove the glove box and check to see if there is an amp.
The stock sound system is okay and if I get bored one day I will replace the rear speakers, head unit and add an amp but for now I just can't stand the front driver side speaker vibrating even at low volume.
