Hey I'm new to the forums but I just couldn't find this answer anywhere on google. I plan on getting a dual vented sub enclosure for 2 12" Pioneers, but I want to order it online since it's a lot cheaper that way. What I need to know is what are the trunk dimensions of my 2005 Pontiac Grand Prix base. I want to make sure the enclosure fits as tight as possible without giving up too much space. All answers would be very helpful.
