"pure SPL" what freq you want to burp at and how much power you have?

he's working with a hifonics amp right , he want's SPL out of it . and as u can see he gave the specs for his trunk and sub's.

im not sure what he want's to burp it at but it's for a daily driver idk if he's gonna do any local comps around here or not.

Thats what I'm questioning... a pure spl car is much different from a daily driver tuning will will be drastically different.

as far as power, I'm questioning what is the ratio of what the amp will put out against what the drivers will take...

If you have a lot of power to spare you can work with a lot more port (which can be better for SPL) if your over powering the drivers you may not want as much area.

So refer to my first question above and I can help out with the design.
