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 ?

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.
