I have 2 jl audio 12w6d4 in a sealed box and I am looking for more bass at lower levels using a jl audio 1000/1 amp. currently I have them in a sealed double enclosure aftermarket box with about 1.3 airspace, would I do better with a different box?

It all depends on what music you listen to most likely I would tell you to do a ported box like 4 to 4.5 cubes after displacement for them at about 35 hertz. How much room do you have in your trunk.

yea if you want a better box to be designed from the guys here, you need to provide your trunk dimensions.

short answer - the box design can make or break a killer deep sounding bass thats solid and works with your setup.

long answer - do you have access to a freq CD or a frequency analyzer?

if so, dont take out your sealed box just yet. figure out the resonance peak frequency in the vehicle, and that will allow you to know the tuning frequency of the port, and also give you the building requirments of the new box using port-to-box references.

what those exact numbers are i dont know. im sure someone could chime in and give you the specs.
