Loud Vibration/Clicking in Middel Console

I just got a manual 1995 325i convertible BMW v6 with 145382 miles... while accelorating the middel console is making a loud vibration/clicking noise. Usually happens when accelerating in 1st and 2nd gear, switching gears, and whenever I am going up hill or press the gas too fast... I don’t know if it is a problem with the clutch or something to do with the emergency brake... PLEASE HELP ME!!! I appreciate it
