New Owner, Stereo Questions

[jeeter15]

Just got my car, 2001 S. Great machine so far, alot of fun to drive. Looking for a suggestion on modifying the stereo. From what I can tell, the previous owner installed a JBL AMP under the hood to power a sub that fits between the driver/passenger seat. What I don't like, is the stock receiver. I assume because there is no antenna, or at least none mounted vertically on the car, that's the source of my reception problems. Some stations pick up OK, but most sounds like they are just a little too far away or not quite tuned in. Is this common?

I'm considering doing one of two things. First, replacing the head unit if I can't fix the reception problem. Second, adding my MP3 player. Does anyone know if the stock CD player has a line-in that I could route out to the front?

Being that this is my daily driver, I need something to listen to while I'm driving!

thanks, Jeeter
