SPL & SQ / Fabrication

We are having a meca sponsered show, and should be a blast , there was about 50 cars here last time, and everyone had a blast. if you have any questions feel free to call us at 269-426-0009 ask for kyle here is the link to the flyer for the show. http://www.mecacaraudio.com/flyers/5-20-07MIv2.pdf

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

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…

is there anyone in the Dallas area that could help me build a box?

My car audio team is holding a Car Audio competition in the town of Lodi. Here is the link http://www.team-bio.com/2nd_Annual_USACi_Sound_Off.htm This would be a nice little meet, for some people who want to come out and have a good ole' time. There will be a ton of cars, a ton of extremely nice cars, and its just alot of fun. Last year we held this event, we have around 50 cars. If you need any additional information let me, know Falout2guy __________________

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.

Powerbass xs15dv2 4.834gross volume 3.997net volume 63.375 sq inches of port (3h x 21.125w) 22.854 port lenght tuned to 38hz powered by orion 1200d @ 1ohm Are my calculations correct? If so do you think that is enough port area? 4.834gross 4.459net 42.245 sq inches of port (2h x 21.125w) 15.344 porth lenght tuned to 35hz Which one would you chose?

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

i want to wall my lincoln but first i need to make sure i wont get a ticket if i do have a wall. any one who knows about that kind of stuff any help would be good.thanks in advance

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…

my question is im trying to make a box for 2 18" btls dimentions are 49"L x 24"T x 27"D here are some rough sketches from paint how should i go about bracing it i know that i need to(or do i?) since im planing on running them on 2 SAZ-3000D and i will doublebaffle the top where the speakers will be mounted would simply corner bracing like in this pic be enuff and also placing a small block of mdf on 1 or both sides of the port to support the middle of the box

wondering if anyone else is going to do SLAP this year, I am not sure because there are not that many shows near me, and I am tight on money to build for competition

its a box for two Fi 15 ssd's. the dimensions i have are 42"w X 20"h X 22"D total of 8.8cu.ft and total of around 8.5cu.ft with sub displacement. and a port 8"w X 8"h X 13"d would tune it to 32hz. thats the calculations i came up with,i just want to double check before i go cutting up mdf.

Sooo...got a bit of a rude awakening today. Found out my e12a is actually presenting close to a 10 ohm load to the PG Tantrum 1200.1 in box - impedance rise is killing me. The sub is a 2 ohm DVC currently wired in series, and it's close to 2.5 times what I was thinking the impedance was. Pardon the extreme n00bish question, but is such a drastic rise common? It just feels a little strange running my sub at a lower impedance than my amp is rated for (if I drop it to 1 ohm), but if it models out well, hey...that's what I'll do.

I'm in need of help finding someone who can make me a second alternator bracket for my 2005 ford escape 3.0l motor I've been in search for months now and can't seem to find anything for this vehicle.

I got 4th in 139.9 after busting out against alpine. But I got to take Bill out in round 1 so that made my day 1-6th place finishers in 139.9 all qualified with a perfect score My scores for the day, 145.0 windows up 145.8 windows down 146.6 drivers down All on music (jeezy, ~40hz) Thanks DC for making a lvl 4 strong enough to hold 2800w rms -Derw

The box is for a pair of DC Level 4 18's in the back of a 2007 Suburban with all seats in, including the third row.I have the following for outer dimensions to work with: 27 x 49 x27 Now my drawing shows a height of 26 1/2, but I'm only counting the height at 25 3/4 in the Box Calc program because the top board was double baffled. I'm seeing a box tuning at 33hz. Here is my other design, this one is pretty much the same as the first except for both subs and port firing up. What do you guys think? Box Design: I think I still like the whole port and subs up design better. My current box is a dual chambered double slot ported box. Each chambered tunned to 32hz. Has anyone…

Planing on tuning it to almost 42 hz. This will be a competition box for my 04 jeep liberty. Subs up port back left. My question is what type of sq foot should i use for this box. Alpine's site says use around 2.5^2 per sub in a ported enclosure. Also if it matters im planning on running these off of a Sundown SAZ 2500d

Hi, i have 2 offers for subs one is for 1 mt 15" quad .7 for about 300-325 and the other is for some 10" xsite D4 which i was thinking to get bout 6-8 for 28 ea. so...which should i get?? i want spl btw i dont care much bout sq... edit: i have a SAZ-1500d and planning on getting a 2nd one

Hi everyone, first time poster on this forum. Posting all the way from Australia. Okay, So I'm in the planning stage for a system in the new car, and I've just started doing up some rough design/placement ideas on Inventor, when I ran in to a problem. I'm designing this for a Fi Q12 ported, and I know the recommended enclosure sizes given by Fi of 1.8-2.5 cf @ 28-33Hz. However, that is quite a large margin of variation for a recommended enclosure volume (0.7 cf and 5Hz tuning frequency can affect the sound a fair bit). As I'm not a massive fan of guessing/speculating about the best enclosure volume, I decided to pull out the calculator and the old loudspeaker design c…

i got bored and decided to draw this up, its right around 2.5 cubes @ 35 hz. gonna be for two 10's ( AQ SDC2.5's) Its gonna go in my chevy std. cab. Any comments or suggestions?

My friend just got his first non kicker sub and he got a fi bl 15 he is putting it in the back of his Chevy extended cab he can make it about 15-18 inches deep 17 inches high and can be up to around 50 inches long he wants his box about 5 cubic feet and 32 htz can anyone help with a design
