Loud banging noise coming from directly under the car?

Question

I thought my tire was flat and I was riding the rim (that's what it sound like). But that wasn't it. I continued to drive and the banging just got louder. It only does it when I drive it. If I park it or stop at a light you don't hear anything. It also kind of sounds like a loud popping noise at the same. I've never heard anything like it before. It's a 96 firebird. Any ideas I would greatly appreciate it. Thanks
