[F4IN 4CH Speaker Input Expansion Card for FORZA]

This is an expansion board designed to add 4-channel analog inputs to your FORZA by utilizing the speaker signals from the factory audio.

It’s suitable for those considering a system upgrade while keeping the factory navigation and factory audio. By enabling the speaker signals from the vehicle to be captured into the FORZA, it becomes easier to fine-tune sound quality based on the factory system and to plan an audio setup that combines external devices.

However, the actual connection method and the configurations you can use will vary depending on the vehicle’s factory audio specifications and the FORZA system configuration. Since it isn’t necessarily as simple as adding the board, it’s important to confirm everything—from how to extract the input signals to compatibility with the existing system and the installation method.

Personally, I would decide whether to use it after checking your current system and the direction of the sound you want to achieve in the future, rather than deciding based on the product alone. At LOGON, we’ll organize this together while asking about the condition of your vehicle and your preferences, including whether a configuration exists where using the F4IN makes sense.
