Help with Enclosure Design

[gb22]

Trunk space is limited, trying to find out which box will give me the best tuning and sound. I have an FI q 12, only listen to rap. I cant find any other pre made designs so I guess I will use one of the free box plans listed in this forum. Btw, those designs seem verysimple so i hope they will still perform well. Dont really wanna pay anyone to design me one. Which would be optimal?

Thanks for the help .
