I have no advice specific to that fuse, but have you cleaned the fuse contacts? Checked the wires in/out of the fuse block? Maybe remove the cluster (after pulling battery +, then reinstalling it when cluster is out...giant mega shorting possibility on removal) and check the ammeter wire connections. Give things a jiggle one by one and you might find your culprit. Of course, this method requires a lot of spare fuses. ;) I'd suggest reading through this outstanding thread that we all read at some point. TONS of awesome info. And get a digital voltmeter (multimeter) and/or a test light.

My first hunch would be to check the temperature sender wire on the cylinder head. Mine has come loose a couple of times over the years and, Murphy's Law, taken out the gauge before blowing the fuse. D'oh.

Well, Since the FJ45 did not come from the factory with an AMP, I would suspect that wiring first. How many watts can that amp put out? Is it possible you have the amp cranked, the heater running and go into reverse and it blows due to simply being overloaded?

The Heater Fuse protects the following: All Gauge power, Seat Belt Warning Relay/Buzzer, Heater front and rear, Back-Up Lights, Brake Low Pressure Warning Circuit and in your case an AMP.
