Just about all stereo amps have a trigger wire AND a power wire.
The trigger wire takes very little power- and is usually connected to the power antenna lead or if not available (say a stock radio) you could use switched source-such as Peter pointed out on in the previous post.
For the POWER wire of the amp- I really don't recommend going to the fusebox- go to the battery. You are asking for problems AND will more than likely bring alternator noise ( an annoying whine that changes pitch w/ RPM) into the system.

By connecting trigger wire to antenna or amp wire on radio you will only power amp with radio on. On ACC you will power it anytime switch is on.
