Yes I already tried the search button.

What is the biggest box anyones ever managed to squeeze through a GPs trunk opening?

Whats the biggest anyones got in the trunk building inside?

I tried a Grand Prix specific forum already but noone really had a clue about car audio they all had small boxes in theirs.

you can fit a HUGE box in there, in my 4 door ford focus i fit a 9.5cf box, yes 9.5cf, all you have to do is built the box IN the trunk, not outside and then fit it in.

here look. yep 2 l7 15's in there and a pretty big port also, its only limited by the amount of work you are willing to do, i did mine in 1 day, 2 x 2's in all the corners and then the box was sealed up and strengthened with a few layers of fiberglass to make it rock solid

I want mine to go in and out, it doesnt have to be easy but I want the capability without dismantling it.

and that is one big box btw

i had 5.5cf in the trunk of a civic and now im glad that i was able to take it out without destroying my car, now its time for another build, i had a 99 grand am, and that trunk didnt make it easy to use up all of its space, goodluck.........

When I put 33" deep and 16.5" Tall into Subwoofer tools calculator it says I need it to be 24.25" deep for 4 cubes net. I notice the depth changes when I change the xmax, why is this? My sub has .2 cubes of displacement and a 26mm xmax.
