I currently have a 12" JL W3V1 in my girlfirends 2008 focus 4 door powered by a sony XM-2200GTX amp. I cant remember exactly how its wired exactly, but I think its bridged giving the sub 500 watts. The sub is in a sealed box with about 1.25 cuft of airspace and it sounds great on everything except the really low frequencies. I had a 12" Kicker CVR in a previous Car and it seemed to hit those really low frequencies better than this JL and it did it on less air space.
I ran the JL in this ported box for a while and wasn't impressed, the sub seemed to bottom out too easily so I went back to the sealed one. This box was free and I have a little MDF sitting around so I don't mind cutting it up a little bit, is there anything quick I can do to change the port and make it sound better? Or would I be better off closing the port and using it as a bigger sealed box?
I apologize for not having specific numbers at the moment but the car isn't here right now. I'll have to go get some numbers on the box and look at how the car is exactly setup this week. Any help is appreciated, I've been out of the game for a while but I miss having a good system to enjoy.
prefabs aren't built that well usually so if possible you may want to just Build one..
1.25 may be a bit small for that sub but im not the britest bulb in the pack

1.25cf is plenty for a 12'' if it is in a sealed application I think maybe a fourth order may be what you are looking for it will be clean tight but also should give you the low end response you are looking for as well.
