i came up with this, can someone double check it?

ehh, okay, well im going to go with about 150 sq inches of port area? 12.098 cubes after port and sub displacement.

Right now i currently have 2 boxes around 5.4 cubes per box @ 34 hz. I know i really could get the BL's to slam the lows alot louder if i got around 7 cubes per sub. SO with that being said im going to make 1 ported box*walled* and tryn get my max dimensions. I was going to get crazy and fiberglass all the nukes and cranny's but im really not the best with just winging it and figuring out port lengths and cubes when its not a regular rectangle. On to my question... Do you find the Sq. inches for port area before or after all the displacements. EX. I have 15 cubes to work with total 45x34.5x20 external dimensions for 2 18" BL's Do i multiply 16(rule of thumb) sq inches x 15 cubes? I was told by FI to go with 14-16 sq inches of port per cube(i listen to rap)... Right now i have 70 sq. inches of port per sub in a 5.5-6 cube box(doesnt hit the lows like i want) My current box is 19.25 deep 34.5 tall and 21 wide Per woofer. ------------------------------------------------------------------------------------------------------------------------------------------- This would come out to be around a total of 200 some odd sq inches of port area for 2 18's.... does that sound right? heres a vid of my set up.. although uncarpeted and not baffled its different now. thanks for all the help and input.

Thinking something like this, but man are these dimensions Close, and this is with a 3.5" port

because im pretty sure the steering wheel would get in the way, and i dont see myself dissassembling my truck in that way. I normally just did it one by one through the passenger door.

Ok i have 43 Wide 20 Deep and 35.5 tall, however dont forget the width has to be in half because the onl way i can get it in is to use 2 separate boxes. 21.5W 20D 35.5T Per Box.

alright, so in conclusion, what would you recommend? i just want to be louder without going hella crazy with power. Throw some ideas at me so i can start workin on a box and ordering some subs. :-) 4 12" Q's ported? I honestly cant go bigger than 6 cubes per chamber its a rediculously tight fit as it is.

i know, i would have them each in 6cubes @ 34hz Heres a pic of my current set up without carpet to give ya an idea. its 2 separate boxes but instead of 1 18 per box i would have 2 15's in them if i went the SSD route.

i walled my 05' crewcab colorado, ive never competed nor do i plan on it.

thats what im thinking of going with as well. You think they would do well off 6 cubes a pair sealed?

Trying to make this as simple as possible I have 3kwrms @ 2ohm to work with roughly 12 cubes after displ. 45W 35T 20D Walled in a CC Truck 4 15" SSD's Sealed or 2 BTL 18's and add another 2kwrms I currently have 2 18" BL's ported but am looking for a little more spl. Its for daily and a groundpounder. I have my 18's in a 6 cube box tuned around 34hz, but they lack the real low end and high end response i was looking for. I wanted to do a sealed set up because its been a while since i went sealed. What do you think? Try 4 15 SSDs or just save up until i can get another amp and go btls in the same enclosure. thanks-

holy bumb! i thought i had bumb but this kid is going to have some mad bumb is the trunk of is bumber. he will probably have crazy deebeeze cuz of his bumb

hmmm... never dealt with that before, how do you plan on powering the woofer? Obviously an amp of some kind, but i never understood how to make that work

correct me if im wrong, but thats pretty big for an 18... and reallllyy low. The lowest id tune that woofer is about 31hz... Id say if your looking for a daily groundpounder do about 7 cubes after displacement and around 35hz, that way you can hit some good high notes and still get low.

3/4" but doubled on the baffle

Actually im not sure if this is under the right topic, but i have seen many asking for pics/vids of their soon to be set ups/installs. Ill start off with a short story I was supposed to sell all my audio equiptment to afford a new truck(trailblazer SS) and i was going to put something small in it in the future, however upon arrival the truck was severely damaged and the deal is beggining to fall through. a month later without bass and no equipment, i am switching my amps from my T10001s(sold) to a Massive Audio p3000.1 and getting a new highs amp... P450.2 for 2 more sets of 4" speakers for my baffle on the side of my wall and another set of KS 6.5"s.... Here is my old set up, i will be keeping the box design, however this time through i will have a few more mids/highs and a few changes, vinly the box etc. I just ordered another BL18 because i sold my other one along with my amps(T10001bd's)---What a waste of money all to buy it back http://www.youtube.com/watch?v=qe21H5vNREU So hopefully my new amp will push these the same if not better than the 2 T10001bd's and also i got a new Loadboss Alternator 250a... i ordered my woofer this morning so hopefully ill have it mid-day next week and finish up next weekend for the local carshow, lotta work to be done still.

your putting it in a 10 cube box @ 20 hz?

Just wanna say i got my woofers after checking the status everyday for 2 weeks... perfect condition and they slam. once again thanks for being so quick and professional, these woofers are amazing. i do have to get more stickers though, 1 per box? cmonnn! -Kyle

yeah just some bad luck, its friday the 13th n my subs are on there way today.... i hope all is well. took 2 weeks for me im 2k miles away

I ordered my BLs last Thursday.. so it took about 4 days to build and i just got the shipping info. Took about a week and a half, im pleased.

There is no doubt that JL is a good speaker. They have excellent SQ and can get loud, but its a fact that they are mainly SQ speakers/woofers. For the price, i would look into some pioneer shallow mounts, or even fosgates P3 shallow mounts. As for the headunit, pioneer has a nice touchscreen and so does panasonic.

did u just powde coat the rims?

print screen it into word save it upload via PB

ok i managed to get more space... 5.3 cubes per chamber including port displacement 34hz with 63 sq inches of port area.

i believe they are strappable but i do not have a bd sync cable... im just using the Master Slave feature on the amps via RCA. So i set the gain to one amp and it sets it for both.. freq and bass boost as well. I know the other kid is doing 2 18's with about 5 cubes and thats not even with port displ. so im sure i can squeeze the extra .4 cubes per box. I want to have a wall with the ports on top. I will get a pic in sketchup of what i want to do and what vehicle it is going in. In the meantime, how much port area should i do for a daily groundpounder? I was thinking 33-36-hz
