Will the warranty be affected after modifying the car with a Berlin sound system?

[Piper]

Modifying the car with a Berlin sound system will not affect the warranty. Maintenance cycle: 4S shops will formulate the vehicle maintenance cycle based on the actual local driving conditions. The maintenance cycle for some components may differ from the one recommended in the official manual. Maintenance precautions: If the local environment is harsh or the road conditions are poor, the maintenance cycle should be appropriately shortened, especially for the air filter element and the air conditioning filter element. Also, the quality and model of various fluids must not be mistaken. Choose fluids with suitable models and good quality. The replacement of brake pads, wiper blades, batteries, tires, etc., depends on the wear condition, so regular checks are necessary. Maintenance items: Mainly include replacing the engine oil and oil filter, replacing the air conditioning filter as needed, checking the battery, brake pedal and parking brake, brake pads and brake discs, brake fluid, clutch fluid, tires and tire pressure, lights, horn, wipers, and washer fluid.
