Fuse or crossed wire?

OK so i was installing an amp and sub in the mustang, and i blew a fuse or have a wire crossed..

The clock on the dash doesnt work
The power locks
And the Speedo all out...

So to save me some time does anyone know what fuse it is? OR any other way to trouble shot this?? Thanks!!!
 
Thank you MustangX.. it just so happened to be Fuse #8 lol.. its just weird that the power locks (not windows) ,speedo, dome light, and dash clock are all on one fuse.. :shrug:

ZakeriD- Blown fuses were caused by an inexperenced teenager who doesnt listen very well... I didnt think i would have to hold his hand doing all of this, but i guess somethings are just better done alone.. :nice:

Thanks again for all the help guys!:flag:
