I need some help figuring out what the best dimensions for my ORION 15 HCCA I want something that gets loud and sounds good that fits in a 99 accord trunk???

I have a 1000/1v2 on a 13.5 JL w7 but I want to know what’s the best box for being Loud and so that it still sounds good so a 60 to 40 ratio pretty much 40 being it sounding good and the 60 is loud so I’m willing to sacrifice sq for loudness. What do you recommend? I want to go the ported route as well.
