Pretty neat idea! Looks good too. Though my cubby is full 80% of the time with random **** I need. So I went for one of those Phillips under seat subs mounted on the bulkhead behind the cubby. £100 does the trick provides some decent bass. In a 90 you could fit two behind each seat. On the 110 I was either going to fit one on the back of the cubby or under the second row middle seat.
