Wall with four 15 inch subs.
|
Silver Member Username: DomenicoGlendale, AZ USA Post Number: 205 Registered: Apr-09 | I am starting my first wall build and need a little bit of guidence. The truck is a 1986 GMC S15 ext cab (2wd) The equpiment I'm using is 15" Alpine Type R I have not decided on the amps yet. I am going to get 2 2000rms 1ohm stable amps I'm going to have the drivers wired to 1 ohm. I think I'm going to get 2 MRP 2000's for the amp... If someone knows a powerfull amp that'll do the job please let me know. What I really need help with is the building part of the project. I've never seen a wall in person or built one. I seen pictures online and have the grasp of it. So.. if a box builder could help me with the blueprints on my project I can get started. Thanks-Dom |

Silver Member Username: DomenicoGlendale, AZ USA Post Number: 206 Registered: Apr-09 | Yes I'm seriously thinking about getting into comps. Do you have some reference links I could go too? The kind of wall I want is competition style.(so I heard) I tried looking for a picture but couldn't find one. It's not a box, it looks like a sheet of wood from celing to floor with the port being on the drivers side seat. |

Silver Member Username: DomenicoGlendale, AZ USA Post Number: 207 Registered: Apr-09 | and I'm thinking about getting 2 2200d from audioque BUT will 4400rms be too much for 4 15s rated at 750 each |

Gold Member Username: LoudonPost Number: 3015 Registered: Jun-04 | think of everything else ull need first ... good electrical which i assume u know already.. on a burp those subs will be fine.. realistically ull be getting about 3800-4k out of th ose amps .. |
|
Silver Member Username: DomenicoGlendale, AZ USA Post Number: 208 Registered: Apr-09 | I'm thinking either dual alternators or a 300amp one. (mechman) big3 extra batts yeah yeah yeah but what I really need to knwo is how to construct it, do you know what kind of walll I want? I know the describtion I gave earlier wasn't swell. I also need to learn about the classes in competing.. that can wait till later once I have my blueprints mapped out. |

Post Number: 15667 Registered: Jul-05 | wait so ur going to use 4 15" type R for comps ? on music those subs shud sound gr8 but i dont know how well u will do in spl there r some guys out there with alot of $ & packing some serious power maybe if u do a single 18 with alot of power of it so u can go in a lower class i compete in iasca stock pro with just 1 15" RE MT off 2 3000D powerbass amps strapped ... i have beaten sets with 2 12s ,1 18 , 2 15s , 4 15s & even 12 10s in a wall my best score to date is 152.5dbs & im no6 on the iasca worldwide list .... |

Silver Member Username: DomenicoGlendale, AZ USA Post Number: 209 Registered: Apr-09 | I kind of figured that the type rs wouldn't be that good of a choise, but it's just kind of a dream per-say to have a wall with 4 15s. Next summer when my season starts I'll be getting some raw equipment when the cash flow is here. Rovin do you know a website I can go too just to learn about competing? Keep in mind I'm not being stubborn, I respect you guys telling me that I'll probably get eatin alive but the truck is for show as well so there are alt. reasons for doing a wall. So back to my question, can you guys help me with the building part? How to caculate port, what size wood, how many layers, how to prep the cab, all that good stuff? |

Platinum Member Username: Rovin1 15 = 152.5 DBs ...Trinidad & T... Post Number: 15671 Registered: Jul-05 | i hear u it will look cool though it has its drawbacks few yrs ago i was going to do a economy set in my wagon with a 8 10s pioneer set - so i started it with 4 10s which sounded really nice for cheap subs did 144.4dbs off a soundstream 2000d on the termlab meter with a 38hz music tuned box but it took up more than 1\2 the trunk in my wagon & its weight too had my wagon moving not like b4 this is it :  those 3 speakers u see hanging on each side are pro audio 10" , 6" & 4" super bullet tweeters entered 2 shows & won 2 trophies but i didnt like how much space it took up so i sold it & bought a single DD9512 which did 143.7 on the termlab meter also in a 38hz tuned musical box so this 1 12 is almost as loud as 4 10s , those who heard it said it sounded about the same loudness...... yet takes up about 1\3 of the space but hey if ur going to do 4 15s type Rs walled u can get 6 or 8 12" type R for a little more $ which will have more cone area & that wud be a sick sweet sounding set ....  |
|
Silver Member Username: DomenicoGlendale, AZ USA Post Number: 212 Registered: Apr-09 | I was thinking about doing 6 12" type rs cause I already have 2 and a pdx 1000. So four more 12s and I would have to sell my pdx and get 3 more amps cause chances are I won't be able to find more pdx1000 off craigslist haha but rovin what I really need is some options I can go with when desinging it. What do you have in mind? and by the way that set up looks godly hahaha |
|
Silver Member Username: DomenicoGlendale, AZ USA Post Number: 213 Registered: Apr-09 | and another thing is the ho alt, what size do you think I would need? 350amp? or would I have to get into dual kits? |
|
Gold Member Username: TejcurrentPost Number: 2027 Registered: Apr-07 | From the numbers most h/o alts do at idle speeds you'd be better off getting two alternators. 4-5kw would hold up very well with 2 200-250a alts and 2-3 large batteries. |

Silver Member Username: DomenicoGlendale, AZ USA Post Number: 214 Registered: Apr-09 | I'm glad you messaged me troy, I have a few questions about your last build and was planning on using some of the ideas. 1) Howd those brackets turn out that you used in replace for the inline fuse holder? 2) what size ga did you use for your speaker wire? Would you recomend me using the same ga? 3) and the bolts you used for the speaker wire that you had bolted to the box, did you have a washer on the inside as well? |

Silver Member Username: DomenicoGlendale, AZ USA Post Number: 215 Registered: Apr-09 | Quentin that's why you always use a flash drive or an iPod. Doesn't skip from the vibration or wear n tear |
|
Gold Member Username: Kingandsons07TEAM NEBRASKA Lincoln,NE Post Number: 1035 Registered: Aug-08 | i use my ipod all the time, but in USACI you must use a CD from a store when your in the lanes, i think troy used 8ga |
|
Silver Member Username: DomenicoGlendale, AZ USA Post Number: 216 Registered: Apr-09 | No sh!t? Well it makes sense but that's dumb cause CDs can jump from the vibration. I'd make an enclosure for my h/u and dynamat the balls outa it hahaha. buuttt back to my post. I NEED HELP!!! lmao dose anyone know a forum where I can look at competition walls? I need to get this show on the road. I'll be posting demensions of how much space I have to work with. |

Platinum Member Username: Rovin1 15 = 152.5 DBs ...Trinidad & T... Post Number: 15672 Registered: Jul-05 | im busy at work these days so i dont have time to calc a box but a quick glance shows : 3x4x1.5ft = 17cft if u build a box without anything in it using 3\4" mdf that already reduces ur space to 14.39cuft if u use 1" mdf thats even less available cuft after u add subs & ports displacement + any internal braces\pieces too : id say u wud only have room for 2 good 15s maybe Fi btl Treo SSX DD9500 RE audio MT RD audio SHW Sundown audio nightshade etc ... |

Silver Member Username: DomenicoGlendale, AZ USA Post Number: 225 Registered: Apr-09 | Well if space limitations is an issue I'll just do a blow through with 6 12s. It doesn't bother me to cut into my truck. okay well that's a lie but in the end I think it'll be worth it. The 12in type r's are decent/good and not to sound like a cocknozzel but they're cheap as well. I found this dudes build log with 4 15type r's Ina avalanch and it turned out amazing. Ill try to find it and post it on here so you guys can get an idea of what's going in my head. ----------------------------------------- and try Mike Jones -- In the turning lane. The song is old as dirt but it's probably the hardest hitting song he's ever had. My neighbor thought it was a bass test cd ha |

Gold Member Username: DeadrabitMarionville, MO Post Number: 2166 Registered: Jun-07 | i wouldn't use mdf. and for a wall i wouldn't use advantech like i did beacuse of the weight. use birch the front baffle needs to be THICK! with 4,000 watts i would make it at least 4 or 5 layers thick and on the inside round it off. so the first hole fits the sub the 2nd hole is bigger and the 3 is bigger than that. so when u look at it from the inside it looks like an arrow port, if u have winisd use it to find how big of a port opening u need. i made the mistake of building a port to big then trying to plug it up to make it louder . if ur having problems with space go ahead and get 4 12s. i have 4 15s now in a wall and i next time i rebuild i am looking and going 12s because my car is so small. keep in mind 4 12s with enough airspace will be louder than 4 15s that are shy of the area they need. for tuning what i did and i would do again is to make 5 or 6 different boards that u can slide in and bolt down the seal up to make the port depth. make on short and one really really long and everything in between. u just put them in and test each one of them with a TL if u can get ur hands on one. really if u want to make a strong wall u will need a LOT of wood. big sheets of wood like to flex unless its in layers |

Gold Member Username: HdubbTeam Revolution Post Number: 4256 Registered: Nov-04 | there is a lot of work that goes into the wall without having the wall in.... are you looking to compete in usaci? or dbdrag? or just local show mainly? 2...are you doing a blowthrough or a ext cab wall? 3. have you tested the res. freq of your s10? i believe they like around 63hz walled off, but thats a blowthrough, i would imagine its the same. IMO a ext cab wall never do good. id either do a blowthrough OR do a stock box design. subs fwd. porgt up. under the window line. if you do it right you can get all 4 subs in under the window line. |

Silver Member Username: DomenicoGlendale, AZ USA Post Number: 230 Registered: Apr-09 | I've looked many build logs, pictures, forums, etc etc So far for s series trucks people tend to do a blow through, I've learned alot about what to use when building a blow through, how to sell the vent, gap between the cab n bed, what sealent to use, how to protech the box from water. What I do want is a bandpass box. I'll post pictures. I believe it's 6th order.. not too sure though. When you look into the box from the inside of the can the drivers are almost seems to be comming to a point. Thanks and sorry to the people who've been helping me, I know i've been scrabbling throughts around and i should have been 100% sure on what I wanted then posted. I really apreciate the help from all of you. |

Silver Member Username: DomenicoGlendale, AZ USA Post Number: 231 Registered: Apr-09 | Here's two different kinds of boxes, I wana do whatever one will sound the loudest, I'm guessing the red one sounds louder. <img> <img> ---------------------------- <img> <img> -------------------------- below is what I don't want. <img> <img> |

Gold Member Username: Livin_loudCOD4 Addict Post Number: 2973 Registered: Jan-06 | well the RE install is our man Steve Meade. he's almost complete with the new 'Ho upgrade i believe. don't quote me on this but i don't think that's a bandpass... looks to be like a clamshell almost |

Silver Member Username: DomenicoGlendale, AZ USA Post Number: 232 Registered: Apr-09 | Which is better for spl? |
|
Gold Member Username: DeadrabitMarionville, MO Post Number: 2167 Registered: Jun-07 | i have talked to the guy with that system. i don't like him. lol i don't think he is getting very high numbers. like 151ish if i remember right but i could be wrong. bandpass can be good. i have seen one kill every one with ported. but if its not build close to perfect i don't think it will be so great, i think that is the same with a wall. if u do build a wall u have to look at the cab as a box and the wall as a box. so it is kinda like a bandpass box but part of the car. u should talk to me on facebook. a lot of people on this forum know a lot about car audio but then again some of them do not. i knnow rovin knows a lot, and i like to think i know a lot just beacuse i have tested so many different things in my car and in my freinds. |

Gold Member Username: Livin_loudCOD4 Addict Post Number: 2974 Registered: Jan-06 | bandpass are considered one note wonders. they peak out at the frequency you tune them to, and don't do so well in the other ranges, which is why they aren't generally used in daily driver applications (unless you buy the sweet @ss plexi glass and neon prefabs in walmart already boxed up and ready to go) to be honest don't know a lot about clamshells except they look sweet and obviously get loud when done proper. |

Gold Member Username: HdubbTeam Revolution Post Number: 4257 Registered: Nov-04 | a 6th order would be a great idea if you decide to go blowthrough. i know alot of people hate this....but....pwk designs is very good at designing 6th orders. i have a friend with one, 4 18s in a ranger. c pillar wall could street beat around a 56 easy and would play down to 28 hz. but the only downfall is it died off at about 51. |
|
Silver Member Username: DomenicoGlendale, AZ USA Post Number: 234 Registered: Apr-09 | yeah I've heard about that, I'd rather just get some specs from someone on here though. Whats the URL for pwk |
|
Gold Member Username: Livin_loudCOD4 Addict Post Number: 2977 Registered: Jan-06 | google? haha. his site was the first thing that popped up for me  that guy has enclosure design down to a science. can't go wrong with his stuff. |
|
Silver Member Username: DomenicoGlendale, AZ USA Post Number: 235 Registered: Apr-09 | haha yeah I figured a search engine would do the trick. I guess Ill check it out, it's 50bones right? |

Gold Member Username: Livin_loudCOD4 Addict Post Number: 2978 Registered: Jan-06 | ... what are the ranges you want your sub(s) to play at. should be something around what you set your filters on your amp to. ex. 80hz upper 20hz lower |
|
Silver Member Username: DomenicoGlendale, AZ USA Post Number: 239 Registered: Apr-09 | Well I figures that. What should the highest freq for a blow through with my equip be? 70 80? |

|
Gold Member Username: Livin_loudCOD4 Addict Post Number: 2981 Registered: Jan-06 | in order to know that you need to decide on what equipment you are using first, subs in particular. without that information it's impossible to say. you would be best off making a sub choice then e-mailing PWK if you plan on using his plans and getting his input. |

Silver Member Username: DomenicoGlendale, AZ USA Post Number: 248 Registered: Apr-09 | 6 12 inch Alpine type r SWR 1242d either 3 pdx 1000 or 3 aq1200d bandpass box (6th order) I was on there forum and alot of people said that he took months just to reply with a rush order included. I'll email him and see what he says. |

New member Username: SeanthemortgageguyKeller, Tx USA Post Number: 5 Registered: Nov-09 | forget the 15's and get 2 or 3 Toby Rangers, they are dual 10" Bandpass subs, literally the loudest, and best sounding subs for a car I have ever seen. Here is the link if you http://www.toby.com/ and there is a video that demonstrates the power of this box. Truly amazing. |
