Ever seen 3 12”s under the seat before that were not shallow mount subs? Now ya have😎 (3) DC Audio Level 3 12”s, recommend airspace is 1.25 each, box is 4 cubes net so they’re seeing ~1.33 each. So yes, it’s proper airspace. 🤝🏽 Some laser etched acrylic windows on the sides, addressable LEDs, wrapped in black vinyl to match the interior. Can’t wait to hear this one in person soon.🤘🏽#underseatbox #dcaudio #subs #bass #f350 #f350platinum #superduty #superdutynation
