what are your max dims / where the box will go / don't forget to measure the opening as well

x2 on the opening!!

just made mine, won't fit in the opening. right now it's in the back seat until the new box is finished (early next week). looks ridiculous back there but it SLAMS!!!!

its going it to a pontiac grand prix i took the measure ments and took 1 to 2 inches off for the sub to flex but the height it 15''

the length is 27''

the depth is 17.5''

the trunk opening is bigger then where the box is going so it will fit

thanks so much
