Factory systems with two antenna inputs are usually "diversity" tuning systems. This means that they're connected to two different antennas of different sizes, and the system automatically uses the one with the best signal. After-market decks aren't equipped for this, so if you replace the deck just use the larger of the two antenna plugs.
