SPL & SQ / Fabrication

Okay, I have a guy that lives behind me that has three 12" Kicker CVR's . He currently has them in a very crappy box and is wanting me to throw a better box together for him. I stand to make a few bucks from this project. that is all. there is no possibility of him competing or even keeping this setup long term. just a better box than he has and some cash in ol' chop's pocket. So for the sake of getting good responses, i am not looking to buy these, i only want to get some good input on what volume and tunning would be good for them to get loud with. not a fart box, but i am sure he has no interest in catching the lows. I have not used these subs before..... off the top o…

I was curious if anyone had any sites i can browse and educate myself on custom fabrication....not real complex chit, just things along the lines of amp racks and custom door/kick panels.... much appreciated

Got a question: Noticed that spl meters seem to have a simple pressure sensor in them. Does anyone know the formula to convert SPL to PSI? If so, I may just make a home brew SPL meter to test changes made. I have a 3-bar map sensor sitting around which can read the barometric at first for calibration, then anything after that. Or am I way off base here?

Alright, so I messed up on my port. The port it skinnier and longer instead of wider and shorter. I have a BTL, and whenever it plays the lows, I feel like its not hitting them as hard as it should sometimes. I guess I don't know how its supposed to hit in the 30hz - 38 hz region. People say songs like Juice box will hit hard, and it barely hits hard for me it seems like... Same goes for some other low songs. Here is a pic of the port in the box: Here is the port that should be 33hz: Here is the port now (the 21" measurement comes from the 22", I had to cut an 1" off to get it to equal the port opening on the back of the box): Could someone tell me what this tuning wou…

im in need of a 3- 4" aeroports at parts express. their kits only go up to a 17" port tube. what should i do when i need atleast 21-24" of port length? i went to my local home depot and compared the pvc pipe with a 3" areoport i had laying around and they do not match up. so do i need to order "special" tubing for my application? thanks!

This has nothing to do with audio, so if this is in the wrong section, I apologize and feel free to move it. The package tray for my hatch was broken when I bought the car. Looks like someone put something too heavy on it and cracked the structure inside. Can I lay chop mat down on top of the carpet and resin it or will the resin not adhere to the carpet? I'm just looking to do the underside of this to make it rigid enough to hold it's shape again when it's in the car. I've heard you should lay rope or something similar to give the mat a corrugated look for linear strength. Here's a picture of the underside of the tray where I'd like to strengthen it. The carpet is hook…

Crown Victorias have some pretty big trunks, i drive one. Heres a pictures Is there a way that i can place ONE piece of MDF and mount it somehow onto my trunk so i don't have to make a whole box. Its my car so i can use up that space however i want, place it anywhere in the trunk.( dont' have to worry about groceries etc.) I want to use 1 board, and the trunk itself to act as the rest of the box. Is that possible or will it be bad for my sub? Any help in this area will help, just bought a SSD 15. Or if you know any other simple ways to not have to go threw the trouble of making a box.

So here goes... I have a 98' Mustang GT Convertible. I want bass in it. It Doesn't have to be anything outrageous.(though my Boyfriend said I should put 4 12's in it) I was wondering if yall had any ideas on what i could do? I Don't Really want it in the trunk though ,for one..trunk rattle really annoys me, and I like to see the woofer excursion. Second My trunk is sealed off from the cabin of my car.. My Boyfriend and someone else Mentioned to me That maybe a clam shell would work in the back of my car, If i took the backseat out. I'm not really sure if theirs any other possibilities that could go on..considering it is a convertible. If there is though, I am open for s…

I purchased this sub on closeout from Parts Express earlier this year when TC-Sounds was filing for bankruptcy. My daily enclosure is a sealed pair of RL-i8's. I'd like to build a ported box for this single TC-Sounds 12" sub but I'm a complete noob when it comes to enclosure design. My typical listening style is loud SQ; typical artists include Smashing Pumpkins, NiN, and Daft Punk. Any suggestions? This is just for fun, so feel free to be creative.

I think i wanna run a buss bar only across the ground terminals of 3 batts in the rear of my vehicle. I can't safely run one for both power and ground if you are wondering. Anyway, the reason why i would want to run one for ground is so i can just run all 3 of my amps ground out to the batt's ground buss bar. This way i can run multi runs of ground wires off of the buss bar, let's say 2 runs of 1/0 off the left and 2 runs of 1/0 off the right. Where exactly do i go to get one and how do i know if it's thick enough... if it'll fit on my batts, etc... they are for kinetiks so i know i can take the posts out of the batt to bolt it back down. I found a site that was selling a…

I am looking for some songs with very good LOW bass notes. The best I have so far are: 24 23 by Trae (and by jeezy, there are two versions), Dopeman by OJ Da Juiceman and In Tha Hood by Trae. Preferably not chopped and screwed (or slowed), as I can do that myself if needed. Thanks, --Chris

I have a 2003 Jeep GCL and i am wondering if I can fit 2 21 inch Wardens in the rear storage area, a ported box would be optimal. I am just unsure if I have enough volume in order to fit the box. If anyone has any experience with the storage capacity of a jeep please help out.

I am pretty serious about doing a blowthrough to my F-150 in the next few months. I am pretty settled on 2 18"s on 4000 watts (will be more with upgrades in the future.) I was thinking of a 4th order bandpass box for them but I want to be loud on low hertz (like around 30-35). How can I accomplish this? Also, what would be better: 2 18" or 4 15" all on 4000 watts? Like I said, I want to be loud but hit low.

Hi, Just pick up a HDS208, Would like some help with a box design. Because i don't know how much Sd this speaker takes up. I'm just looking at a 1cuft box tune to 35hz. look at a box 14x20x10 external measurement with a 3inch aero port x 16.5 Please advise, Gao

Ive got a sundown 3000 amp and a 300amp circuit breaker. ive been to a few comps and my circuit breaker has blown in some of my runs. Is it ok to run the system without the circuit breaker just for comps?

I'm working on a box design for a single ported SA-12. I looked at the Sketchup design they have for a 1-12 ported, and I came up with this for my vehicle. It seems pretty dead on. Is the 13.5" x 2" port too narrow? The one in the Sketchup is 14" x 2" so I figure it's good. Thanks.

When using a PR in place of a port, you would keep the same internal box volume as the equivalent ported enclosure, correct?

does anyone have any rituals before they go in the lane?

ok ill give a quick run down of what i would like to do.. i would like to build an upside down L box.. with the slot port going into my cabin.. and my subs on the long part of the L inverted. to save space and show off motor... here is a pic of my trunk. the top part is is 10 tall... 19 deep and 41 wide. from the floor to the step level is 14 and from the floor to the top lip is 26 and i want to port thru the rear deck ill cut this all away i know its kinda hard to picture what im talkin about... ill come up with some sketches of what i would like.. but im wondering WILL IT WORK!!> i need some where around 3 cubes and tuned to 30htz thanks guys, ps. not…

so i want to use 2 10" aero ports, sono tubes,... and i dont know how to find out how long they should be, i want to start off at 32hz, on a box that is 15.4cf or a box that is 16.6cf, i want to put the ports in side so do i have to subtract the area space of the tubes or just find the calculation with out taking out the area space of the tubes???

i just finished my 5 CuFt box for my fi bl 15 and i used just about every square inch of my MDF wood i had for the box. my question is if its ok to use 3/4 inch plywood for my second baffle? i have a bunch lying around and would be nice instead of buying a huge sheet of MDF i would barely use. lemme know what u guys think! Thanks!!
