my gramps use to say "it takes all kinds" .... referring to it takes all kinds of people to make the world intresting!!! it sure does!

going with this on first build ........ will attempt to experiment with different style enclosure perhaps Janurary starting build tomorrow... it will be under the build log section!!! thanks, chop

I think I got my first box design down, hope to have you guys double check it all for me....... tunning will be at 35 hz. port area is 62 sqaure inches box volume is 4.29 ( havn't figured out what the 45's and braceing will displace) I just used 4 cubes for all my math. useing 3/4" mdf and will use double baffle. port opening will measure 15.5" W X 4" H , useing the bottom of the enclosure as the bottom of the port, ported to the side. port length will be 27.5" long the port will fire toward a vertical mdf wall on the drivers side. sub will fire up, and i will plan on having it inverted, for now. it will work out that the sub will be almost centered in the vehicle. keeping in mind this is not a comp build so the pressure i would put on the mic is not factored in. the sub will be the furthest away from the internal port opening. 43.5" W X 17"D X 16"H i think that is all the info needed, planning on useing the 1 5/8" coarse drywall screws, predrilling and countersinking all holes/ useing wood glue and clamps, gotta look up prefered name brand of glue still. will either caulk with normal caulk or look into useing more of the same used on first box, high velocity duct sealant < this sh*t is tuff stuff now! planning on useing internal braceing and 45's, leaning toward 2" X 4" 's for braceing material due to cost, even though i like the look of the all thread better. will round over all angles and sand box down, the finish will start out naked due to low funds, slowly becoming all black. everything will be blacked out in the rear, it will either be black or chrome.....with white strobes, (slow) well looking for any and all input as usuall, so let me know what you think newbies, and gurus please check my math! thanks guys, chop equipment is in sig!

see anything in there about subwoofers only? nope, me either. with no attempt to judge here, just geniunally curious, what sort of setup / install do you have, if any? o, and when it says "HIGHWAY" , what, if any diffrerance is that to, well lets say street, parking lot, driveway, or private property...... once again, just curious???? thanks chop wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

uh, so you do have subs and amplifier installed in your trunk? ones that in which upoun visual inspection, suggest the ability to get loud? this is what you are thinking of hiding? Why, again are you wanting to hide them from the proof of your sound system? just not sure if i personally ever got pulled over for nothing, i have my ticket proudly displayed as a trophy in another post, so i am not being a hypocrit (sp?) here. if you indeed was not playing it loud.... then no, don't hide it , but speak your mind in court in your defense, at least you will have told your side..... not sure hiding something is not sort of admitting it is indeed wrong? has he perhaps heard it before or perhaps a complaint call sparked his intial arrival? don't know, just asking.... our cops don't fuck with you unless you are in the wrong..... like i was! 4 12"s @ 4K, doing 146's.......write it up, i got caught.... the trophy part was we were on the strip every one is banging, we were just alot louder, lol.......... ticket said bass could be heard 200 feet away setting off car alarms! priceless. we respect our neighborhood fully and we abuse our cruise strips equally.... do you have a area where it is considered okay? yeah, I say if you feel you need to hide anything , you are sorta guilty....pay it....and also post a build log up, we want to see it!!!! if you feel there is no way it was you, keep it in there , but be sure to at least tell your side in the court room. chop

hey hank...... still waiting on the crx t be shipped over here......

http://i162.photobuc...soneisright.jpg sooooooooo, we like this one with the amendment of ; dividing the H in half and subtracting that from the port length, as opposed to adding ......?????? thanks chop

thanks fellars ....... hey i wanted to note that there is a "wrong" way to foam....... it is exactly how we did it!!! FTL the thought process was to fill the areas super full, tape it off to avoid any big leaks and be done with it = FAIL the foam needs that extra air and space to do it's thing......if you over fill the voids it will restict the air flow, it will expand, only to shrink and turn into some nasty liquid junk at the bottom of the cavity, we have done this lots of times but always real slopy and just did not attempt to prevent the over flow spills.... little did i know, this is the way it should be done half ass at a time and sloppy..... lol. ......well lol now, anyway. the foam needs the air...then it does great....let it dry then it is easy to remove... if it is a surface to be protected , tape it off using masking tape , go wild, let it dry then remove all the mess and tape....this will be FTW. just wanted to throw that in there..... will have completed pics of big three and the painted panels installed tomorrow..... Mikey, big thanks for the door speakers... Steve, thanks for all the help.....

ready to hear it

o, i see , cool

too cool, i am still learning all about the tunning, i like seeing bilds that are a little different, unique! i think i am tunning this first box to 35hz. , i was thinking this would be too high at first, lol..... i am anxious to see what this will do for me..... i bet you got a few hours in that enclosure!!! uh, after taking a second look, where are the ports??? lol. i can't find them....

43hz. , wow, i like all the shapes goimg on in this build, gives alot to look at. the lighting is definetly a nice touch. nice build all the way around, thanks for sharing. chop

right on.... trying to get Alex to sleep, then i am going to tackle the next one

http://i162.photobuc...soneisright.jpg i used this one and came up with 29.58" using that math.......that seems alot longer than what you had suggested @ 25.5" this is with a additional 2" added to the answer, if i were to subtract the 2", then i would of been at 25.58" ........... so am i really that close to getting it right, subtract instead of add the 2" with this formula ????? chop

i will take my numbers and run them through the formulas again..... keeping in mind what you have said. i am determined to walk away from this with a complete understanding of what to do and how it's done.... did you take a look at the two i have....port length calculation formulas........ do they appear to be correct? thanks chop

roll on will tend to deliver better coverage and texture..... if spraying, a spray gun ddelivers the better coverage in comparison to a rattle can..... spraying in either fashion requires the most prep work...... i would suggest grabbing a couple of rattle cans for trim work or hard to reach areas and roll on the rest..... another thought process could be to take the vehicle to a truck bed liner shop..... it will cost more and the more prep work you do, the easier they will be on your wallet..... a fellar at our state fair had a demo of a pop can that he sprayed.... you could not dent this can....not at all. he said $350 to $400 for a complete trunk and lid color matched to our car..... if you do straight black, alot cheaper.... prep work is the other factor.... the roll on stuff is easy enough and is good coverage.... sometimes you can get a deal on it as well. chop .02

also was wondering why we do not have this info in our "how to" section or a link to it at least..... i mean like a pinned post that can be referanced easily enough? chop

somewhere in that post i was to ask if these are good ones to use....

okay......... i think i understand some of what yo are saying, i will re-check my math....mainly because i think i aleady did this.... am i confused still or is there a typo or mistake in these two sentences.......... sentence # 1 " So, in a slot port, you take half of the width which is 2" here and subtract it from the required physical length." ......... so this is saying "SUBTRACT".... sentence # 2 "The port wall depth itself would only need to be 17.25" deep, then add 2" for acoustical length - 19.25" then add 0.75" for wall thickness - 20" " ........... and this says " ADD " ............. what is going on here? if both calculations stand true...subtract 2" and then add 2" , ... i end up the same place.....0 - 2 = -2 + 2 = 0 !!! i use these........ http://mobile.jlaudio.com/support_pages.php?page_id=165 http://i162.photobucket.com/albums/t246/Kickerlivenloud/PortLengthsolved--Thisoneisright.jpg thanks for the help so far... get me the rest of the way now, lol chop

so, I finally got my crap together enough to take a closer look at begining this box. I have a couple of questions perhaps to help better my understanding of the concepts applied. first off, port area.....12" to 16" sq inches of port area is suggested per cubic foot.......i went with 62 sqaure inches (4" X 15.5" = 62" ) ........puts me at 15.5" X 4 cuft. I am powering the sub at rms. I want it to be loud, but not just farts, daily music loud. I was under the impression that I should go with a larger port area....to get louder....is this correct? I am asking because when shizzzon redesigned the port, he also changed port area......smaller. second problem I am coming across is port length......I cannot find a consistent formula to design the port length.....it is cool to find answers on your own....you know?! so, I have read that there is no two port length calculators the same..... okay....well I am confused about what the hell one is right? I mean I floated a design around in a few places and found no consistency, I mean a couple of inches differance in either direction.....? I don't want to question any ones methods....I just want to find a method that is consistent.... consistently correct perhaps even. It is very important to me that I learn this and learn it correctly. If I need to back all the way up yo learn it correctly, then thats fine. any input our links to info would be great..... I am planning on rereading the info I have located so far... attempting to apply it to these designs, hoping to find a consistent bases in wich I can count on and apply to build designs. again.... any and all info would be great, input is fine....draw it out, step by step, help get ol' chop right....100%. thanks alot for the help, chop

first and foremost,,thank you for your prayers, they are needed and do work! It feels good to be part of something that is real, I am glad that we have all of your support. Alex has a very aggresive skin condition that is resulting in large, puss filled blisters, (3/8" to 5/8"), they are very concerned of them entering his blood stream (at first they thought it had already) they have taken countlees bllod samples, they have taken cultures of the sore itself, (by cutting the sores literally off), and also strapped him down on a board and done a spinal tap, removing flood directly from his spine, all of this has been sent to labs, it is a horrible sight to see so much trama to a new born. he is in a very reputable hospital here in Indy, and they have included the neighboring hospital help, in which is a complete childrens hospital, he has what they cal a team working around the clock with him, consisting of eleven doctors, all of who have nurses and interns as well. he is in isolation until they can identify what has attacked him, we have to gown up and gloves, mask, footies, before entering a second doorway, and remove all of it before exiting, everyone has to do this. there is no fever, and he has all healthy baby signs, just a very aggressive skin condition, they have given slight hints but no true info has came of it. they are saying it could be 24 to 48 hours still for first results and realistically several weeks before he is home again. please keep praying, your prayers are stronger than 100 of their teams put together, I know he is in the best hands, and i know the lord will see that they are guided in the right direction. thanks for giving a listen, helps to get it out. Chop p.s. Samantha and Paul are being super strong, they are going through hell in all of this. they are great 'new' parents.

lol, she is referring to the enclosure covering..... as Jay-cee was saying...... i believe she is wanting any info or leads to where to get the fabrics at..... hey sis , when you buy it, get enough to cover some panels and stuff in the car..... any pics of these type of installs? chop
