Need help with bass strings

[TheParasprinter]

Anyone know where to find bass stings heavier than .130? Do they make such a thing, and if so, where would I find some? I want to tune my 5-string to a low A, but don't like the sloppy sound and feel I get when I do so. The problem is probably just my cheap-ass bass more than anything, but since I'm a broke college student, I'll just have to improvise.

Know where to find thicker strings?
