Single 12 build

[PinkFreud65]

Been here and asked a similar question before...this time I've got the all good from the Wife! looking to to a sealed trunk build in a 06 Mazda 3 SEDAN not hatch. Probably for a sundown X 12 on a CAB 1600.1. So, I need a ported box built not sure on tuning so I'm open to options.

Max Dim. of box? Keep in mind that it needs to be able to slide into trunk or else you will have to build in the trunk.

41"w X 18"h X 20"L then the trunk gets wider and it's like an additional 10-12" from there. not certain on the actual trunk opening I can check later.
