However, I would recomend upgrading speakers as well as the reciever... and an amp. I absolutely love my setup. I have a JVC reciever (with outputs... you might want to look into something with this if you ever want an amp). It goes to my Alpine amp (sure you can get others, but this one was on sale... with free installation. I was too lazy to do it myself). And you just wire the speakers to the amp (pretty easy because you have all the room in the world to wire shit in the back than in the console). I can help you with wiring and installing if you want, just drop me an e-mail... may save you money on installation, and guarantee a job well done.
