Well the box was actually to big to fit in trunk openings as I didnt take into account the tail lights when I measured and the opening was to small in the back after I took the seats off to slide it through....I had to bend the sheet metal up some and remove carpet to push the box through and it still took me like an extra 30 mins to turn the box so the subs was facing the trunk lid. I dont plan on trying to take the box back out till I sell the car lol so I think they will have to be ok at 35hz lol...Im more geared towards SPL anyway and sundown recommends a higher than 30hz tune for that so hopefully I will like it...
