I’m working on a new truck build that will feature three 13” JL Audio TW5 subwoofers. In order to fit these subwoofers in the vehicle though we need to measure for and design a custom under seat subwoofer box. In this video I take you through the planning process for this custom downfiring subwoofer enclosure.
