      Note: *Additional charges A materials charge of $5 per vehicle will be assessed at time of installation. Standard installation does not include any vehicle-specific parts or accessories (for example, amplifier power and signal kit, line output converter for factory stereos, etc.). For an amplifier installation, these parts typically cost $79–$199 but will vary based upon your specific vehicle and the amplifier you are having installed. Additional charges for vehicle-specific parts and any non-standard installation will be assessed upon completion of the installation. If you'd like more detailed information regarding installation on your specific vehicle, find a store with an installation center and speak directly with a Geek Squad Autotech. Your Geek Squad Autotech will provide an estimate to you prior to performing work that requires an additional charge and any additional parts. See terms and conditions for further details.
