My wall project

Gold Member Username: BestmankindFi AudioBTL Post Number: 7377 Registered: Oct-05 | k guys. ima build a wall for my car starting next week. i need a few pointers so if anyone have any suggestions let me know. couple of questions for you guys. i don't want to cut the headliner so the edge of the wall is going to be about half an inch from the ceiling of the car. what should i use to fill the gap that won't damage the headliner? should the face of the box be a little slanted or should it be straight? 10cu ft, 9 cuft, 8 cuft? 120sq inch of slot port or 6 4 inch aeroports? like i said any input is appreciated. thanks in advance. |

Use at least 2 layers of MDF. 3 for the baffle. second, dont be afraid of port area! third, subs on passenger side...as close to the passengerside wall as you can get them, stack them staggard if you have to. |

Gold Member Username: BestmankindFi AudioBTL Post Number: 7382 Registered: Oct-05 | yeah i was thinking the same thing B but i have a problem. i can only do 30 inches max height. my subs are 15s. wouldn't it be a bit crowded? will it sound good for daily also if i tune low? like 36hz? |
|
Gold Member Username: RedlinerWilmington, Ma Post Number: 3120 Registered: Jun-05 | as marshall said stagger them if u have to so put one in the lower left corner and then put the top one a little to the right if u cant stack them straight. yea it should still sound good but if ur going for a wall i would say sacrifice the sq and tune a little higher like 40 |
|
Gold Member Username: BestmankindFi AudioBTL Post Number: 7383 Registered: Oct-05 | well plenty of wall setup tuned low that sounds good charlie. i doubt i will tune that high cause i want to maintain some sq. i don't want a straight spl car. |
|
Gold Member Username: SouthernrebelMonroe, Louisiana DD 9515d~~]... Post Number: 3883 Registered: Mar-04 | do option B. use masking tape and expanding foam to fill the gaps around the box. 'daily' and 'wall' really dont go togther, but 40hz would be ok. when you wall the car, it is prolly going to want to peak at a much higher note than it would want to w/ a box in the trunk. you may want to build the port so you can block part of it off and retune lower for daily driving |
|
Gold Member Username: RedlinerWilmington, Ma Post Number: 3123 Registered: Jun-05 | ya i know what u mean chad i just figured u were going all out for spl so just trying to help chad but ya 36 would still sound great but chad when u make it please take pics along the way |
|
Gold Member Username: BestmankindFi AudioBTL Post Number: 7384 Registered: Oct-05 | lol charlie you know me. i like to take pics of stuff. so option B with a 10 cuft box. tune to 40hz with 160 sq inches of port. does that sound right? also marshall, is 2-3 layers of mdf really necessary. can't i just brace it well and just do 2 layers for the front baffle? i don't want it to weigh it down. 150 seems like its right around the corner. lol. |

" There is a black foam pipe insulation that would work well. Its cheap, comes in 6' lengths, and has a slit in it. Open the slit and slide it over the MDF and then snug to ceiling. As far as the other stuff, your own your own. |
|
Gold Member Username: BestmankindFi AudioBTL Post Number: 7385 Registered: Oct-05 | thanks marc. that would work perfect. i am gonna cover the face of the box with black vinyl so i will cut it enough to cover the black foam stuff too. you think can use that to cover the gap in the side of the box which is like 4-5 inches? |

Gold Member Username: Van_manBoston South, MA Post Number: 1326 Registered: Mar-06 | this is just for the idea on the black foam. http://aolsearch.aol.com/aol/imageDetails?invocationType=imageDetails&query=foam +pipe+insulation&img=http%3A%2F%2Fwww.perfectwave.com%2Fimages%2Fpacking01.jpg&s ite=&host=http%3A%2F%2Fwww.perfectwave.com%2Fpacking_tips.html&width=120&height= 76&thumbUrl=http%3A%2F%2Fimages-partners.google.com%2Fimages%3Fq%3Dtbn%3AHmhRjgq 6i9XNiM%3Awww.perfectwave.com%2Fimages%2Fpacking01.jpg&b=image%3Fquery%3Dfoam%2B pipe%2Binsulation%26page%3D3%26userid%3D-396977058899277683%26invocationType%3Di mageTab%26clickstreamid%3D3323805516133912222 For the sides, get some of those Swimming noodles. they are kinda thick. You could electrical tape up 3-4 of em in a bundle and stuff em in and cover with vinyl. http://www.pooltoy.com/noodchairand.html |

Gold Member Username: BestmankindFi AudioBTL Post Number: 7386 Registered: Oct-05 | thanks marc. those stuff will work out perfectly. i just don't want it to be permanent. i want to be able to take it out later. |
|
Gold Member Username: Van_manBoston South, MA Post Number: 1328 Registered: Mar-06 | yea, It will make a nice neat install. That expanding foam stuff looks like poo poo. You see some installs and its all over the place some one puked over it all and never cleaned it up. |

Gold Member Username: SouthernrebelMonroe, Louisiana DD 9515d~~]... Post Number: 3884 Registered: Mar-04 | The 2-3 layers of MDF was for SPL...kinda going all out. I see walls w/ 5-8 layers of MDF for baffles all the time. just brace the hell out of it and you should be ok. 160sq inches tuned to 40hz should be ok for a daily/spl wall. 10cuft net and you could make the port 20"x8" and ~16" deep. Maybe even do the wall w/ interchangable ports...now THAT would be shweet. You vehicle will prolly try to peak at 55hz+ w/ a wall though...if you do interchangable ports, you would be able to play w/ the tuning very easily. |

Gold Member Username: AdddisorderWest palm, Florida Post Number: 2043 Registered: Jan-06 | look on some other fourms too they have wall building stickys. although it seems like cannan and B got you coverd |
|
Gold Member Username: StnorrisDavenport, IA US Post Number: 1805 Registered: Apr-06 | do an interchangealbe like me! then you can run 33 - 36 daily and 42 - 45 for spl. its alot of calculating, but i bet canaan can help you (lol marshall haha givin u more work) or winisd works easy to design ports. |
|
Gold Member Username: BestmankindFi AudioBTL Post Number: 7387 Registered: Oct-05 | "10cuft net and you could make the port 20"x8" and ~16" deep. " if that is the case then the port wouldn't have to bend cause the depth is around 38 inches. i can just make a plug for the port so it would tune lower for daily. i can't wait til i get started. actually i can't wait til it gets done. it will be one loud azz mofo. lol. lots of progress pics for you guys. |

Gold Member Username: FrkkevinResonant Engineering..., Fort Worth... Email Post Number: 1750 Registered: Nov-05 | if you want to get your note with a wall.. build the wall 50inches away from where the mic will be and use the 1/4wave formula.. only works if the wall is 50 inches away... but yeah your sacrificing daily with a wall so your best bet is to tune where you will peak and just build some port plugs so you can plug for daily or street beat |
|
Gold Member Username: BestmankindFi AudioBTL Post Number: 7393 Registered: Oct-05 | at the comp they ran a sweep and my car peaks out a 51hz. should i just port the wall at 46hz for a insane burp? lol. naw i still want nice sound and i think i can achieve that with a lower tuned wall. |

|
Gold Member Username: BestmankindFi AudioBTL Post Number: 7395 Registered: Oct-05 | okay this is how it looks inside my car. as you can see the box is in the middle of the car and doesn't really have anything to resonate off of. this is why i want to build a wall. to minimize the air space and also i want the subs to be at the edge of the listening cabin. i hope i am making sense here. my car is just damn too hard to get loud.  |

Gold Member Username: RovinTrinidad & T... Post Number: 9992 Registered: Jul-05 | nice ride ^^ - lol yep im liking that removable port idea too ..... |
|
Gold Member Username: RedlinerWilmington, Ma Post Number: 3130 Registered: Jun-05 | interchangeble rem do it right the first time so do it the best way first dont build one then want something else so do this and make it amazing u will be so happy after i promise or i offer a money back guarantee lol |
|
Gold Member Username: BestmankindFi AudioBTL Post Number: 7408 Registered: Oct-05 | ok ok ok. interchangable it is. i will dedicate my wall to you charlie. lol. i will make 4 ports consisting of 32hz, 36hz, 40hz, and 44hz. i might make a 50hz port also cause my car peaks at 51hz right now and with the wall it will peak higher. ima go tint my windows this week so i can get start on it next week. |

Gold Member Username: BestmankindFi AudioBTL Post Number: 7410 Registered: Oct-05 | btw guys if i do a wall i would have to compete with this guy.   that little car is hitting 154+ db with only 1 18 inch sub (i don't know what sub) and 1 amp in a wall. he puts a piece of paper in the port and the pressure from the port tears up to pieces. |

Gold Member Username: SouthernrebelMonroe, Louisiana DD 9515d~~]... Post Number: 3888 Registered: Mar-04 | OMG....that is Quad's car! (Leonard) he has been known to start alot of sh1t on the dbDrag and Usaci forums. he always talks sh1t...i wish i had pick of the install he had a finals bout 2yrs ago, some of my friends told me bout it. The called it the 'quad-wood' box...looked like it was built out of sh1t. BTW...you can get 154's out of those BTLs and 2500d's if you really work at it. A friend of mine, Pat Day, used to do 161's w/ 2 MT15's and 8 crossfire 1000d's. |

Gold Member Username: BestmankindFi AudioBTL Post Number: 7412 Registered: Oct-05 | awesome man. i didn't know he was famous. lol. one of the nicest guy you can meet in person though. very helpful. whenever he gets in the lane, he takes out his seat and has a little box that holds his stereo from the outside. i am gonna take my time with this one marshall. i want to get it right. i will post progress pics so you or anyone can give me some suggestions. |
|
Gold Member Username: Tdeaton1021Near Tampa, Florida USA Post Number: 3463 Registered: Sep-04 | do a 3 section port with ALOT of port area tuned to like 45-50hz. Then make it so that you can bolt panels over 2 of the sections to greatly lower tuning for daily driving. 5 minutes can take you form daily to SPL. |

Gold Member Username: RedlinerWilmington, Ma Post Number: 3156 Registered: Jun-05 | yea i feel special all of a sudden chad lol good luck building it man hope it comes out awesome and gets the job done |

Gold Member Username: BestmankindFi AudioBTL Post Number: 7414 Registered: Oct-05 | ok rob. you see the diagram of my car above. what kinda box can i do to increase spl? it can't go in the trunk cause it won't fit. |

Gold Member Username: BestmankindFi AudioBTL Post Number: 7417 Registered: Oct-05 | awesome canaan. i love wall. wall is your best friend. the thing about my car is the wall cannot go down that low. i can only have 31 inch height. i measured everything yesterday and i have it all planned. gonna use 1 layer of mdf all around and 2 layer for the front baffle. gonna use 1"x1" wood for the coners and also make a H shaped brace for the sides and the back. then between the front baffle and the rear, i will use 2 x 4 s for brace. i will also stiffen the inside with resin. this wall is going to cost me but when i read 149.9db playing the song "da blow" by liljon, it will be all worth it. 140-149.9 bass race class here i come. lol. |

Gold Member Username: SouthernrebelMonroe, Louisiana DD 9515d~~]... Post Number: 3908 Registered: Mar-04 | B, I have seen quite a few SUVs walled behind the second row of seats. Not nearly as loud as walling them behind the B-pillar, but you usually peak at a much lower note. I saw 4 soloX 18's on 16 kx1200.1's so 156's in the kick like that...the wall was not your typical wall though...whoever did it really didnt know what they were doing, they had separate chambers for each 18". The would have done ALOT better w/ 1 chamber. |
