Default Major Electrical/Battery/Car Stereo Problem

Alright folks, I'm new to Corvettes and have already learned so much from these forums. But I've got quite a doosie for ya. Here we go ...

I'm a car stereo guy. I have installed the same system in every car I've owned, from a Ford Probe to a Mitsubishi Eclipse to a Chrysler LeBaron.

After buying an 85 C4 last week and installing all my stereo stuff in the exact same manner as always, I turned on my Vet and it immediately shot me into reverse, pushing through the E-brake and even the brake pedal. I turned it off just in time before hitting a wall. Soon after I turned it off, the battery started smoking. It eventually cooled down, so I disconnected it and went to bed.

Today, I did some small troubleshooting. All my stereo fuses were fine. My ground point for my amp and capacitor were fine. The battery, however, seemed dead. So I went to the store and picked up a new one.

I connected the new battery and DID NOT connect the amp/capacitor power cable to the battery. I just wanted my sweet Vet to start! As soon as I connected the battery, immediately a loud humming/buzzing noise came from near the engine. After a couple minutes the buzzing went away, so I got in the car to start it up. But as I turned the key, the car shot in reverse with each attempt for the engine to turn over! But alas, it never actually turned over.

WHAT THE HECK IS GOING ON!!!

Disconnect everything that you have done and retrace your steps. Are you sure that you have all the wires connected to the correct wires?
