For this sporty sedan, we offer a unique Stealthbox solution that doesn't compromise significant trunk space. Twin 8-inch subwoofers, capable of handling 150 watts of power, fire through the rear deck of the A4 without any cutting of sheet metal required. The woofers are enclosed in a solid fiberglass enclosure that positions the speakers up and off the trunk floor. Grilles for the woofers are included.

Power handling: 150 Watts

Final load: 4 ohms
