Who's fit HUGE boxes in their wide body Grand Prix?

[SomeDonnieDude 10+ year member]

So debating between 15" and 18", not sure if I can fit an 18" in my trunk though. What's the biggest box (max dimensions) anyone has ever squeezed into a 97-03 grand prix? I have about an inch less that normal on the height due to my semi-false floor.

I was originally going to cut part of my rear deck and wall my trunk off, but I'm going to sell it here before long, just not sure how long as I said I was going to sell it since last fall lol.

Ive got a 4 cube box after displacement and port in mine with a 15". Should have room for an 18" if it requires a small box.

ya i got 4 cubes in mine easily. with out cutting or building the box in the trunk i dont see fitting an 18. the trunk opening sucks and behind the rear seats without cutting the medal is hard to fit a big box in.

I know a guy personally who fit an 18" Nightshade in his GP. He had to build in trunk though.

Is this 34w x 15.5d x 17.5t?

Could anyone else post dimensions is they could, thanks!

I had fit a 28"x32"x11.5" box last summer, but had to slide it from the inside. Glad I never had a flat tire with that box lol.

Just because they are both pontiacs dont mean there anyting alike. Ive owned a Cavalier [sunfire], And installed a system in a GTP and let me tell you there is NO resembalince as far as fitting a box threw the trunk opening. Thats like me saying since my 83 grand prix's trunk can fit xxxx box, his Grand prix should as well.
