SPL & SQ / Fabrication

A buddy of mine wants me to build him a subwoofer box for two 12's in his Ford Ranger Edge. Now he is taking out all of his rear seats which gives me a good chunk of space to work with. I know how to build and design an enclosure, all i really need to know is subwoofer/port orientation. Havent made an enclosure for a truck like this and I dont have the time to build multiple enclosures and test them all out so I was hoping this could save me some time. -Mike

Hey there! I need serious help building a ported box. Ive never had, nor built a ported box and i want to see for myself what the difference is. Ive tried every different box calculator i can find, but im sad to say there a little too complicated for me to understand. Im a rookie when it comes to car audio specs. Im a pro at listening tho lol. I want to learn more, a lot more, but everyone close to me dont want to teach, they want to charge. i could easily build a sealed box, but i really want to port my subs. I have 2 lethal injection 12's. I need 4 cubes, 60 square inches of port and i want it tuned at about 32hz. Space is not an issue. I took the back seat out of my ra…

the box specs 48w*40d*20h port is in the center 18.5h*14w*22d what would this tune to and is it to much port for this box.goals daily ground pounder. subs 4 15 db drive plt15wd 2500rms

Hey guy I need a good beating song with a long bass line ( about 3 min) box is tuned to 32hz and my car peaks around 40-44 on burps. I need a song that will last 3 mins. I have a comp in the morning and there is a kaos class ( average spl score over the 3 mins) I haven't had any time to try any on a tl any one have any sugestons?

I have a zvx12 and a sk800.1 I need box advice I want to invert it in a 2000 durango, need advice seald or ported what size box do u think I should go with any advice would be great thanks

right now my box is subs up, port back 20 cubes before subs and port with about 200+square inches of port tuned to 33hz, designed by chris at fishercustoms. It picks up lows and pretty loud, only metered before i built this box and was 149 on tl and did 151.7 on audiocontrol meter at local show. Now with this box, it sounds louder to ear, but havent metered yet. Problems now are i have bought 2 boxes of stinger roadkill bulk, did roof, doors and back door. It doesnt rattle bad, the back glass is terrible, but everytime i open back door, metal braces or pieces of the lock and handle are broken and fallin off. LOL. I got guy i work with to tig weld a rip in back door alread…

i can design a sealed box fine. but how do i add the port? i cannot figure this part out!! especially when using 2 woofers and putting the port in the center. or even putting the port at one end or the other if anyone can give me some simple directions or a link to some i would greatly appreciate it

My buddy had talked to me about building a box for his F-150 for 2 12" Xplods. Looking around I think it may be possibly to get 5 Cuft. (or very close) for the 2 12s. behind the seat I was curious what is the best way to face the ports and sub. I think the only way to face the the ports is up, but I do have the option of either down facing them down or foward. What is generally best practices for SPL?

hello hello. ive just built box for (2) Nightshade 15's, its tuned at 33 hz and really gets down.. im trying to brace my box and dont wanna take a chance of screwing up my tuning and overall eclosure. my box measures 49x24x20. with a port opening of 18.5hx8.5t. i guess im seeking advice on placement and what exatly would be the best to use. my face is doubled and my overall box is 1.25 thick.

How could I brace my port more, or do you think it needs to be braced? Here is the bracing of the entire box, but it is also for an idea of what the port looks like... also, do you think a 45 would be helpful in my port? I don't think it would make much of a difference....

they had it locked on to show just the highest db hit, so idk what i made on tones. my sweet spot is somewhere between 40-45hz but i hit 135.7 with my single 12" FI Q w/ BP Option, powered by SAE 1000D my first box, tuned to 31hz playing the opening of Tortilla Chips by T.Bizzy. mic on driver side dash, passenger door half down. in a 2001 Jeep Grand Cherokee. sub and port facing back hatch nothing fancy in here. i know when i bought it i was curious of some numbers, i know it's not made for SPL but i was somewhat impressed with what it did.

I have 1 PSI P1 15" sub in a 4.5 cubic foot ported enclosure. I have a 6" diameter aero port that is 10.5" long. My box is a 6 sided wedge design and we are trying to figure out where to place the port. I have a 2010 Hyundai Accent Hatchback and my box is in the very back. Here are my 2 options. Option 1: Port on top of box next to the sub. Option 2: Port in front of the box on the angle. If the port is placed in front it will be a few inches from the back of the seat with the seat up. If it's placed on top it will always be in open space. I would rather it in the front so i can blow more air towards the passengers but i dont want the seat to interfere with the sound qual…

What wood glue iis best to use and caulking should it be hard or more elastic like for sealing?

I need a box for two AA Mayhem 12s, and Ive got the external dimensions, trunk dimensions, port lengths and everything. I just need someone to build it because I am in the Army Active duty living in the barracks and I cannot build a box, I need to order one. Please post if you know if a website, or if you know of someone that can build me one. Greatly appreciated guys!

What is best used to paint the port latex? Or oil based mine is a wall with top port so it's the first thing you see just wanna make it pretty and any color sugestions?

its going in my 92 civic 4 door in the rear seat area i was thinking sub up port up...but curious to see what sub up port forward would be. only reason to go in that area is because we could barely get a 5 cube box in the trunk without beating some stuff in box is gonna be 6 cubes at 36hz anyone have an experience in a setup like this one? im not sure if its exactly legal in most comps because the box itself is gonna be over the window line unless they would consider it a wall?

I bought a box i just saw some of the glue is coming undone so im gonna glue it again and screw it down and seal up the inside. But i need to know what it is tuned to here are the measurments thanks in advanced. I have an L715 in a ported box the measurments are 16" h 40" w 17.5" d and the port is 3.5" w and 13.375" deep. I would like to know how many hz it is tuned too and how many cubic feet it is after port and sub displacement. Thank you

I wanted to paint my port chrome and layer it in plexi. What would provide me with the greatest reflectivity as far as spray paint goes? I looked into mirror finish film but it seems to be quite pricy. I wanted to spend around 50 dollars max for about 25 sq ft.

2 fi bl 12s ported box dunno if it will fit in my car its a 2012 ford fusion.I like to hear rap music and deep and low

Im looking to make a box for 2 12inch kicker l7s. I want the subs to have individual chambers and to face up. I want to use aero ports and have the ports facing back. I want to use 3/4 inch birtch plywood. I am having trouble to come up with a design. I want to tune it to 32hz. I am looking for help with this design and I am looking for opinions on what I want for this box. I want it to be loud with little distortion. the width of the over all box cannot exceed 40inchs and the depth of the box cannot exceed 24inchs.

2 part question, lol. 1). I'll be getting an '05 Chevy crewcab next week sometime, and I was wondering if it's possible to get 2.5 cubes anywhere from behind/under the rear seat? 2). If not, I may consider a blow through. The problem is I dont want to cut a big hole. What effect on tuning would building a box like this? Thx for any/all help you guys can give. :clap:

hi, what is the rule of thumb for port tuning to gun for in SPL install? 45~48hz? cheers

i need a free box design program to run on my mac thanks

I was just wondering how much space between the end of the driver to the wall of the enclosure is sufficient? Meaning what wont hurt the driver or sq/ spl. I'm thinking of a 15" havoc ported. The xmax spec is 30 mm if that matters. Thanks in advance and merry Christmas to all.

I got a box built for my 2 Funkin Audio 12" subs but something is wrong with one of them So I used 2 of my Mass destruction napalm's I had never used them before. I had the box built at 2.742 cubes ported to 40 for the funking audios the Mass destruction napalm seem to be doing ok and they seem very very loud.. My question is do you think they will be ok in this space or should I get 2 of something else like the BTL that is good up to 3 cubes.. I am running a xxx-6500d and they seem to be taking it ok I don't want to push them just yet as they are brand new. Open to suggestions don't want to smoke to new subs for sure.
