The DV8 Offroad speaker and light bar mount is designed for the 2021+ Bronco 4 door models only. Mounting to existing accessory mounts in the factory rear cross bar, our mount allows the expansion of your sound system and lighting. Manufactured from 2" round tube with plated steel for the mounting locations for the strength and rigidity needed, then protected with a micro texture black powder coat for durability and matches most of the OEM trim. The bar itself measures 29-inches in total length with a 10-inch slotted flat mount in the middle of the bar and 4 wiring holes, 2 towards each end, allowing you to hide wiring inside the bar. There are several possible configurations available based upon your accessory choices. Two speaker cans with roll bar clamps can be installed, with up to a 6-inch light bar or two 3-inch pod lights on the flat mount. You can run a 20-inch light bar across the length of the bottom if utilizing the back rail mounts on the bar. Alternatively, a speaker bar up to 28-inches wide with roll bar clamps can be mounted across the bottom of the bar. Note no lights, or speakers are included with the mount.
