To find the relevant fuses, you need to consult your owner's manual. It will have a fuse box diagram showing the fuse locations and what each fuse protects. Look for fuses related to:
* Radio: This might be explicitly labeled.
* Power Outlets: The radio may share a fuse with power outlets.
* Accessory Power: A general accessory fuse might control the radio.
The Impala typically has two fuse boxes: one under the hood and one inside the passenger compartment (often under the dash). Your owner's manual will guide you to the correct box(es).
