On many units the yellow is the power wire that needs constant juice (otherwise your settings will be lost) and the red is the "trigger wire", which needs to be hooked up to a keyed wire.

So first check that both of those have juice, yellow always, red with key on. Make sure that you have a ground. Use a test light close to the unit so you can see whether the power is getting there. It could also be that the plug in the back is not in firmly. Or that one of the wires has a break, since they need to be stuffed in there.

Replacing a fuse with a higher rated one will almost surely cause you problems, and may destroy your unit.

If a fuse blew it could mean that one of the speaker wires has worn insulation and is grounding somewhere.

Again, the best idea is to install your own new wires, which assures that you won't have problems in the future. That way you KNOW.

It takes a lot less time to install new wire than to troubleshoot the old ones. Plus, you get better sound. But if you enjoy fault-tracing, have at it.
