Box Placement In Trunk

[Crownvicon28s 10+ year member]

I'm in the process of designing a new box for 4 more 12's, but the box I designed is like 4 inches from the back of my trunk would this cause a problem? Will the subs being so close to the back of the trunk cause cancellation or damage the subs?

Seriously doubt that, I have had (4) 12s in my Crown Vic before, sealed, and currently (1) 15" ported (at least until this weekend //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif and both were close to the back of the trunk.

Still sounded fine, I think you will be ok.

My 2 12s are literally like 2 inches away from the back of my trunk and it still sounds fine

My box is firng toward hatch with aeros about 4.5" away and its fine. Some say the closer you get, the louder you get.... could be just a theory though

Do you have a picture of your current box, I have a 97 Mercury Grand Marquis so it should be about the same trunk size and I was curious how you made your box.

I roughly calculated that if you use the "wings" out on the side of the trunk (youd have to assemble the box in the trunk) you could get 7.5 cubes and not go much higher then where the spare tire shelf is at, but that was just a hunch and It might be to complicated to actually do.

I dont have my spare tire in my trunk. My current box is 16'' long 40'' wide 24'' tall subs and port facing back. New box will be 20''long 40'' wide 25'' tall. 8.32 cubes gross 7.72net after sub, box, and port displacement with a 4.4 inch wide slot port tuned to 33 htz. This box is for 4 RE SE 12's. If the subs were facing up I could get alot more volume but its not as loud facing up port up. Box could be 24X40X25, which is about 10 cubes after box and port displacement tuned very low about 29 30htz. You could get alot more than 7.5 cubes out of that trunk.

Right I was saying 7.5 Cubes if the box wasn't much taller then 18" and utilized the outstretched part of the trunk, you would just have to assemble the box in your trunk cause you could build it externally and fit it in.

Yeah your right. I just took my spare out. Wife can bring one of my regular wheels if I get a flat.
