well i dont really see any other choice for it. look at the picture on my last post. thats the picture they showed us from indy. that is what the system looks like. the way the subs are , yeah its going to kill trunk space. its 2 10" subs. there isnt alot of room for it and the best place to put it is in the middle. if it were 2 separate 10" subs you could do 1 on each side of the trunk. but they come together and sit in the middle of the trunk up against the rear seat.
