SPL & SQ / Fabrication

So Im collecting parts to do a blowthrough in my fullsize chevy regular cab. 1988 k1500. Just bought a crescendo 3500. gonna get a singer 250a alt and a couple 3100s and one up front. multiple runs of 0. okay so now for my question. i have been pondering ideas on sub/box setups. I have been set on 2 18s for a while, but got to thinking about 4 15s. and idk whether to a 4th order or just a regular ported box. i can do the rregular box tuning but would need some help designing a 4th order as i have read and have yet to wrap my brain around it. My goals: Daily, Hairtricks (move air yo) not super low. 30-32 (in regular box tuning terms) not sure where that would be in a 4th o…

Im new to building enclosures and would like to know the correct type/brand of screws and glue that i should be using. Thanks for the help!

So im building my first box out of 3/4 mdf...what size bit and screw should i use? Also whats the best glue i can get...money aint really a problem right now so give ur .02...

I want to try out a transmission line box or quarter wave, whatever its technically called, and want to know if im off to a good start... I want to use a 10" Fi BL Dual 1 so 41.5fs with an sd of 310cm^2 = 48in^2 1130/41.5/4*12 = 81.7 inches... so my design looks something like this... I dont know much about these kind of boxes it just sounds like a fun project, If it turns out horrible I only lose a few hours and a little off my wood stockpile...What do you guys think about this design and these measurements?

just wanted to get some thoughts on bass box 6 pro..is it user friendly for a noob box builder like me and if so does n e one have it avail for a small fee

Where is a cheap place to get some 3" Aeroports ? I saw them for $13.88 on this site, just wondering if there are any places that are cheaper. Its gonna be about $35 shipped for 2, which isnt the most appealing thing ever

Anyone tried this? http://www.splenduro.net/

Well thaks to McVay in Oswego we finally have some "local" shows scheduled for the 2005 competition season for IASCA. The first show is on March 27th, with one show a month all the way up to the month of October. I don't know about the rest of you guys but since I was unable to accrue enough points towards Finals last season, I just can't wait to get back into the lanes this season.

ALright, I'm getting to the point of install. I am curious about the whole gain knob deal. I have always just turned it up to where it sounded good, and went on. I remember reading something about matching low level volts? So, anyway, my headunit is a whopping 2volts. - that goes to my Phoenix Gold EQ, which has a built in line driver, adjustable from 1 to 8 volts. Then, back at my Memphis amps, they are able to recieve between 1 and 4 volts. SO..gimmie a run down on how to get this stuff adjusted properly..or is there a link that could tell me and save somebody the typing?

Just as the title says, I'm paying this kid 10$ for a box design. He is going to be working with me to help figure it out what would be the best results, I think so atleast... Is that a decent deal?

In this video I show you how to cut a perfect circle for your car audio install: What you need: Router (Preferably a plunge, but I show you can use a normal one) Jasper Circle Jig Drill 3/16 Drill Bit Wood to cut a circle into The Jasper circle jig in the video is the Model 200. Search Google for "Jasper Circle Jig Model 200" to find it. Mark

hello all i have a system installed thanks to the great guys at phoenix gold and its really fricking loud which attracts the hoodrats and hence, i have no window now. So i went to go get a new window and the thing is almost 700.00. so i looked at lexan and that is way frigging cheaper. so heres the deal. How in the hell do you install this crap. i know i am supposed to be able to cut it with a jigsaw and like sand it or something but i dont really know how or what techniques to use or anything else. i need to know how to put this in or someone that does it needs to do it for me but either way i need the big fatty lexan in there. Since there is literally nothing on this su…

Been bumping my 15" SSD for a while now and I'm still loving every second of it except for one thing. The rattle. Its not the trunk rattling its my back deck speakers, and the reason their rattling so bad is because the sub is firing up towards them. My dad had to buy a special bolt and locking nut to keep the screws from backing out because every time i listened to it the screws holding the back deck speakers in backed out about 2 inches. Its really annoying, you either have to listen music with the bass so low it doesn't rattle them or so loud you can't hear the rattle. *And I'm not taking the back deck speakers out they help fill the cabin with highs So here is my plan…

alrighhtttyy guys.... i got a different build that i need some help with because i realized the two SPL15s had a slim chance of working out =[. I'm putting a ascendant audio mayhem 18" in the trunk of a 01 chrysler sebring sedan. The sub is going to be front firing and im just going to keep the back seats down (when i put them up for people to sit in them i will just cut the subs off). The trunk is pretty flat and the box should be pretty easy to load in from the car with the seats folded down. I have L29 x W34 x H18 to work with. for you who dont know a mayhem is essentially a loaded BTL.

Hello , I need a new box design for a friend. It is for a Soundstream XXX sub in 18". Power : a Soundstream XXX 15000 amp !!! It is too much, but it's what my friend have bought !!! He'll have to turn the gain down for daily listening. He wants to compete in spl but needs to be able to listen to music. Can he have a way to change tuning / port easily ? The box will be like a wall, panels will be added to the sides of the box to make it look & act like a real wall ! Here are the max dimensions : 38.58" (Height) x 35.43" (Width) x 31.49" (Depth). If it is too big, we can have it smaller, just tell us. He wants 45's in all corners, and some kind of slot port. No tube …

I would love to use PR for car audio application. Before I start designing the system I have a couple questions. 1. Will the automobile environment be too abusive for PRs? With a vehicle in motion, going over bumps and accelerating/deaccelerating, cause the PR's cone to move affecting performance? 2. I have read that downward firing a PR will cause the diaphragm to be displaced downward. If the PR is mounted cone up will the cause a similiar situation (diaphram sinks towards spiders)? In my current vehicle the only way I can use PRs is with cones pointed upward.

hey guys my friend has a cda-9855 that has a big green wire what does that do becouse it was cut when he got it will it work with out that wire thanks

If i use a flared areo port in a 2.5^3ft box would one four inch be alright that would be 12.5 square inches port area. Box will be for 4 8" subs

hey guys i have a 2006 toyota tundra access cab. currently my sub is in a 2.5cuft box tuned around 32hz. its much too small. it is being powered by a percision power black ice bk1300.1d. and i have been fiddling around on sketch up trying to make a box to fit nice and tight up against my seat in the back passenger side. the box will be roughly 4 cuft with 2 4" pvc ports. will this be enough port area for my sub? the box i have it in now has much too small of a port. i am planning to tune to around 30hz this time. sub will be roughly in the center of the two front seats firing foward, with the ports facing the drivers side. there will be one seat still usable in the rear b…

Do I fire my sub towards my trunk lid or into my vehicle? I have asked several people and now I'm going to ask the proz.....which way would yeild the better sound? I head that on paper it should be the same? Could you guys tell me why i should do either or? PLEASE - THANKS
