Which fuse is for radio?
Most low-powered radios can use a 20-amp fuse without any issues. However, for high-powered stereos — those that produce 100 watts of power or more — you may have to use a 25- or 30-amp fuse. You may be able to use a wire clasp or harness already under the dash to secure the wiring from the radio to the fuse box.
How do I know if my car radio fuse is blown?

Always replace the fuse with one with the specified amp rating. You may install the next-smaller-rated fuse to get you by in a pinch until you can purchase a replacement. Clamp the grounding lead of your test light to a metal component. Turn the ignition key to the “run” position. Then probe both of the tiny test ports in the face of each fuse.
