Fi Q 18 on a kicker zx750 sealed enclosure question

[bs1991 0]

So I just bought my new car, a toyota celica, and I am going to have a custom box built for my q 18. with a kicker zx750, how many cubic feet should I go for? I am looking for a flat frequency responce and a good balance of sq and spl. I know these are all really rough terms but I just could use some advice.

Go the biggest you can basically. A Q18 is doable in a 4-8 cube sealed box. The larger the better, so take measurements. If you can't fit 4 cubes in your Celica then go with a Q15. 2.6 cubic feet isn't much at all....

the bare minimum recommended box sizes won't give you flat responses either.

Are you looking for sealed or ported because a ported box for that is 5-10 cubes.

IF you go ported, you're gonna need almost all that room so u can tune very low to attempt to get a smooth response.
