No, you should not connect an amplifier's remote wire to a car fuse for power. The remote wire is a *signal* wire, not a power wire. It's a low-current wire that tells the amplifier to turn on and off, usually triggered by the car's radio. Connecting it to a fuse, which provides power, will likely damage the amplifier.
The amplifier needs a separate, much heavier-gauge power wire connected directly to the battery for power. The remote wire should be connected to a switched 12V source, often found in the car's fuse box (but not directly to the fuse itself). This source typically turns on and off with the ignition.
