Need some audio help...

Does anybody knows what size or dimensions can fit the 2 compartments in the rear trunk. I'm trying to build 2 very small boxes to fit two 8inch subs on each side. But I want them to be completely flush. Anybody have any knowledge on this or has someone ever done this.



Also if someone can give me specs on what size speakers this truck uses so I can try finding upgraded replacement speakers. Thanks for the help if any in advance!
