Hi, my name is Frederic, I am in France, I am 30 years old and I am an electrician in a college. Really saddened for my language, but I use a translator !

I am the happy owner of a DC 18" XL Dual 2 ohms. Will be running off SoundStream TRX 2000D with 1/0 AWG and a Optima Yellow Top 4,2L.

The vehicle is a Peugeot 207 SW.

The box :

- 8,61 cuft total

- 7 cuft

- 0,25 cuft displacement woofer

- 112 sqare inches of port and 15” length

I don’t know the frequency of the box. More it’s low, better it is !

DC 18" only

And in the car

And my new Clarion (DXZ588RUSB)

But I have a problem, the frequency of the port is too high according to Box Tuning Calculator (39.94Hz). I listen to musics slowed down from 20 to 40 Hz, the box has difficulty in reproducing them.

If I reduces the port, that will be good ?

Before :

Future

I'm going to add a wooden thickness above (port length : 15"--> 16"). By reducing the port could I shoot from 20hz to 40Hz ?

Thank you in advance.
