    Just wondering about a 4 order box for this sub. Could it be done? Would it be louder on the meter and still musical? I've heard lots of great things about 4 order boxes great frequency range, more flex, better spl... plus I've started to chase numbers too haha but I love listening to music on my current box it's not as loud on the meter as I hoped but it is tuned lower also so keep that in mind. So what I really would like to know is a 4 order going to play as low as my current box but be just as loud if not louder? Could I please get input and help on this maybe even some designs? Thanks guys

    Thanks so much man couldnt have done it without your help man. The electrical will definitely help and you'll have give me some pointers on the big 3 haha

    Glad I could help out man. Anytime you need some help on somethin just shoot me a text and we will get it done. The big 3 will not be a problem at all. just have to get use to soldering and after that your good. I think once that voltage stays 13.8v+ you will see near a steady 2k rms.

    I'm going to upload the pics of the box design below. Got to get them on photobucket and ill upload them shortly.

    Thanks for uploading my box design man the only difference on there is that the port width ended up being 6 inches right? which tuned it from 32

    hz to 30hz

    My local shop has a termlab so I was curious what my system would hit. I have a 2002 nissan xterra with a hybrid psi/fi bl 18, crescendo bc2000 wired all to one ohm in a little more than an 8 cu ft box tuned to 30hz. Well I metered 141.8 for my peak and that was on stock electrical. I am purchasing an xs3100 soon and doing the big 3. Also I will sound deaden my roof, my trunk is already deaden but I will be deadening the trunk even more with some great stuff to make it heavy. But anyway was that a good number with all those factors in play?

    id probably try putting a sundown audio sticker on the window first, before you spend all that money. it will make you 30 points cooler and give you 15db, which is well worth $5 for the sticker.

    Haha yet I don't run sundown but that may help... If I put kicker comp stickers I'd hit 180dbzzzzzz haha

    Id start with the box.

    I've thought about maybe trying to design a removable port or something like that.

    Don't deaden yet. I lost a few tenths after deadening my hatch. My hatch like to rattle. If anyone even touches it, I lose .5. What frequency did you peak at? I personally think you would see an upgrade moving to a box that closer to 6 cu ft. tuned around 34. But still be musically.

    Post up some pics of your box and install so we could help better. But yes, I agree. Start with the box.

    Is there anyway I could mess with the current box you even think deadening the roof wouldn't help because it looks mad. my roof is going crazy plus it doesn't sound great outside either because of that...

    john253a he is a member here. It is also tuned to 30hz though which is low my next box when I go for two 18s or a bigger 18 I will make a removable port for numbers I think the tuning is killing me... well that and the lack of deadener the guy at the shop said I could be losing an easy 3 decibels from all the rattling which could be the case when I first deaden my trunk I notice that it got louder it sounded loud that was just by ear with a 10.

    Well I want to compete so is that not bad for competing? I like just giving demos too though but like everybody I want to get louder. your sure electrical wouldn't help? my voltage dropped to about 11.8 maybe even a little less on stock electrical but it was only for a few seconds and the amp will push more power with steady voltage going to it most amps are rated to 14.4 volts right?

    Okay my depth without the amp rack is 2ft x 7 inches to the top of the seat that was with the trunk closed all the way to the trunk. and 3 ft all the way at the bottom of my seats the seats sit at an angle. Hopefully this added space will help design an appropriate enclosure. Thank you.

    Okay just got the sub today! Here are the dimensions in 3 ft x 6 in for the width, 2ft for the depth I made an amp rack that takes up depth space if more space is needed I will remove it and mount the amp to the box once its built and the height is 1ft x 4 inches and that is right below the window line. Thank you for the help.
