Wrapping up this custom subwoofer enclosure for an Audi A4. Built from Baltic birch and designed specifically to house a @garmin_audio 12W7AE-3, the goal here was strength, clean fitment, and solid construction. This enclosure is designed to sit clean in the trunk and be part of the finished look, not just something hidden away. The end result? You’ll have to stay tuned... . . . #agouraautosounds #caraudio #audia4 #customenclosure #jlaudio #eurocars | Agoura Autosounds
