For a 1968 Ford Falcon, 6.5-inch speakers are a popular choice for the front doors, as they fit well in the available space. If you want to add rear speakers, 6x9-inch models can be installed in the rear deck area, depending on the specific configuration of your Falcon. Always check the depth and mounting requirements to ensure a proper fit. Additionally, consider whether you want to maintain the classic look or upgrade to modern styles.
