Is it safe to tap into a cars fuse box?

I want to tap into my accord's fuse box. I'm probably only going to draw about 2 amps worth of energy max. I was just wondering if it is safe to do so. I'm thinking about tapping into a 30 amp fuse, maybe a 20 amp fuse. More specifically, I'm wiring 2 cold cathodes (700mA inputs) and 1 remote amp wire.
