Electrical System Keeps Dying

Ok I replaced all the Battery Cables, Positive and Negative, Grounds, and the other 2 wires that come from my Positive Terminal on battery. Things were going kinda smooth for a bit, but I had the occasional hard time starting it, and then one day I drove it for a few minutes, tried to crank her up again and nothing. Not even an attempt of a low battery or anything. Complete electrical system dead. Not even enough juice I guess to open my Power Door Locks. Now im assuming of course the battery could have been crap, after all it was like a $40 battery i got from Walmart, but, a couple days later when I was not home my wife said the Alarm system went of. Now if my car does not have enough juice to even open the doors how can my alarm just go off by itself? I dont get it. Could this be a short somewhere? Faulty crap battery? Im clueless, and before I take it to a shop I know you guys here on 6GCelica are pretty dam smart and have helped me with issues in the past.

This probably is not enough info to fully fix my problem, but I will post whatever it is you need to know. So please let the trouble shooting begin.
