I have the Sony xploit (I think that's it) cd, USB, and AUX plugs on the front and iPod interface if you use the USB. The sound is 10,000 times better than the stock stereo and I didn't ECM ge new speakers. And another great thing is that when I had the volume turned all the way up on the stock, it's the same volume as 15 on the Sony. This thing gets the mirrors shakin on 30. Best deal under $200!! Highly reccomend. Also When they installed it, since it's slimmer than the stock, they put in a special front with a place to fit the apple iPod wire, 1-2 iPods, and the stereos remote.
