Well I may jus be a lil too hood lol but my shit was always sliding around, an when i decided to drift corners an shyyt it would sometimes even get unplugged... so all I did was take a tie down (like wat you use to hold down furniture or dirtbikes) an i hooked it to little spots in the trunk an tightened it... before that I jus used a bunjee cord an that worked good too, but the tie down is more secure.
