I hooked up a DD9515 with a jbl bp1200.1 in my friends car hes complaining because itts not nearly as loud as my blazer was with the 2 of them, He is running his sealed and still need to upgrade his power..... Tell him how big a difference having a tuned and custom ported box is vs a sealed box expeccialy for this sub and him wanting it super loud... i already know the answer

Dear friend of OP,

WHY THE HELL ARE YOU RUNNING YOUR DD9515 IN A SEALED BOX? AND WHO THE HELL TOLD YOU TO PUT THAT DD SUB IN A SEALED BOX?

YOU ARE WASTING THE POTENTIAL OF THAT SUB.

BUILD OR BUY A CUSTOM PORTED BOX.
DON'T EVEN THINK ABOUT RUNNING IT SEALED OR IN A CRAP PREBUILD PORTED BOX.

You could also give it atleast 2x the power it is getting currently. DD subs are ridiculously underrated.

Ported would be the way to go for any SPL application.

And thats even MORE true with a DD sub... they are designed to perform well in a certain box... there is a reason DD does not recommend sealed for any application.

^ Simple, DD drivers are designed to have less xmax and more motor-force, for use in a ported box. Efficiency vs. displacement.

he'll gain 3 to 5 decibels by going to a ported box, and it'd be of great benefit to have an electrical system that can support that amplifier too, before he fries the sub from clipping the amplifier.
