Audio/RKE Fuse keeps blowing.

Had a dead battery and replaced with a new one. Since then, radio and remote keyless entry don't work. All other electrical stuff works (lights, signals, horn, cigarette lighters). Checked the fuse and it was blown, put a new one in and it instantly blew again, haha.

I'm assuming there's a short in the wiring somewhere but just wanted some knowledge from some of you guys. Has anyone else ever had this? Will it cause other problems? Am I going to have to replace the radio?

I found another forum where a guy had a similar problem but his horn and other fuses also popping. http://www.aveoforum.com/forum/f108/...blowing-11625/
