i get the impression you need to learn a lil more before you talk...^^

38 hz is a good target freq. for tuning...

it will get loud too...

nice sub

2-1 - Id tune 33-35 hz should be pretty optimal - roll out some pics

hd3 tuned to 40hz sounds good...

9500's sound good at around 36ish...

33hz for really deep bass...

but my L7 was tuned to 40 and made a great dd...

straight from their site, I cant seem to understand why you chose the APXX for a daily driver takes ALOT of power to even get it moving, the APX would have been a better choice, but to each their own, with that power 4500 do you have the electrical to support that or are you just going off the amp/amps ratings? I would say 6cubes tuned at 36hz is going to be your best box in that hatch back.

I

like

the

sub

bigger box is you can do it! I have had my APX 18 in 5.8 cubes, all the way up to 10.2 cubes, and it just got louder and louder and sounded better and better. I would do around 7.5 tuned to 36-38 for best results.

APXX isn't really a daily sub though, APX would have been a better pick as stated above.
