Trunk Audio is a Car Specialities customisation option in Need for Speed: Underground 2. It allows the player to customize the boot of their car with LCDs, subwoofers, speakers, amps, nitrous bottles, and neons.
There are multiple layouts available for each vehicle in-game. Each layout is unlocked differently with each offering different compositions and component slots.
Need for Speed: Underground 2 allows the player to select one of three boot layouts. The Custom Layout is the only part to feature large slots. Neon can be equipped with Custom Layout boots only.
