SPL & SQ / Fabrication

i know its kinda of a noob question ... but how big should i cut my counter sink hole, like the diameter

Okay so I want to build my own box of time I've had my box built in the past for me. Mostly leaning towards the sq side. I want to build something loud this time. I seen read a lot of stuff on here its got me confused. I did try downloading winid on my laptop but couldn't exactly get it to work right. I left it alone for a couple weeks cuz I had plans on changing my subs but they fell thru. since then my laptop has died and I do not have a way to use that program to figure out what kind of numbers I need. So if somebody could tell me port size and cubes to build i can use those to make a design. I have 2 zcon 15's. Cresendo 3500 on each turned down a bit. Thinking 31hz. I…

so i need the calculations needed to figure out my problem(or the answers) with this build want it to be a true not done on a online cal.(unless one will give true port cal within a 2hz of needed frequency) box 20h*48*40*d using 6in PVC? thanks to all that have any input for me. its 4 15s and want to tune between 30 to 34hz.

i just went on car stereo.com and i have a 2 cu.ft. box and to tune it to 34hz with the sub being an icon 12 the round port would be 4" diameter and 11.72" long is this right

do aero ports have to be straight or can they have an elbow somewhere in between .. also when designing a box with an aeroport does it need 90 on the edges ?

im trying to fit two lethal injection 15's in a 06 monte carlo. so according to looking to specs they say that i need about 3 cubes min. i was wondering i could fit a box that big in a 37 w , 36 l , 16 1/4 h. i am also open to using aero ports if thats what i have to do to fit the enclosure. thanks for everyones help in advanced

does anyone know if a single sundown audio sa-10 would sound good in a box tune at 45hz ?

Has anyone done one of these before ? I reciently picked up a eD e8a and I wanted to try it in one. I found a formula that seems fairly simple to follow. Build a box with 2 chambers, one at 3 cuft and the other one EXACTLY half of that, ie 1.5 cuft. Next cut 3 ports all IDENTICAL in length. Put one in the face of each chamber and the third in the wall separating the two chambers. In this instance each port would be either 12.5" long for a little deeper response or 8" long for a little more SPL. Now you have a box with a big chamber with a vent in it, a small chamber with a vent in it, and a third vent in the wall between the two. The woofer also mounts in the large chambe…

i've got a sealed box for my rl-p's. its built into the well of my car and is a major, major pain in the ass to take out of the car, or i would just pull it out and feel for air moving at the joints. when i push one of the speakers in, the other will push out, and very, very slowly settle back. is this normal or does that mean there is a leak somewhere?

So I've had the car a year, and after a spring break trip to Florida, I found out that it's cramped with three passengers and luggage for a week. My brother should be getting a car within two years and he wants the current set up, so I'm getting a head start on my planning LOL, ready to pull the trigger when I get the money to do so. I built my own floor for the extra battery and some storage space. The sub box currently fits across the whole trunk from the back to the break in those side pieces. I want to put together two separate boxes, each to house either an SA-8 or an SD-8, sub facing back. I still want to keep access to my spare, so the cover I made for it …

Unfortunately due to some extenuating circumstances this year's event has been POSTPONED!!!!!! The Clayton Chamber of Commerce has postponed this year's Clayton Classic Car Show. Since the show is put on in conjunction with the Classic Car Show, we have to postpone the Clayton Car Stereo Show. We will be in close talks with the Clayton Chamber of Commerce and see when they will decide on a new date for the Classic Car Show, when we get a new date for the show I let everyone know and we will try to have it then.

I am planning on designing a box for my rli-8s I am getting and I am trying to figure out a way to latch down the box in 2 places. I want the box to sit in the well for daily driving and I want it to sit up top when I take the t-tops off. I want to design something like the back seats on the nissan quests. There is a compartment where it hinges down into to stow the seats. I am thinking about going to the junkyard and looking around for some hinges and latches that I could use. Does anyone have any ideas? I can draw it up in paint if yall want. Thanks guys

jsut curious who all is excited that both will be offered in the ame even? I know me and my team are. Who else?

I had a last minute change of heart and decided to scoop a pair of Obsidian 18's. Can anyone give me a general idea of what size to build it? I am still going to get a BC2000 or a SAZ-1500 (The sundown is so much prettier .-. ) and I would like to tune it lowish for chopped and screwed music. Is 26hz too low to be realistic for music? I don't listen to hardly any rock or metal, mostly slowed rap so tightness and accuracy are hardly concerns of mine (my xplodes are going into the fire pit though) What would be an optimal size for a pair of 18's? Once I get a feel for how big it needs to be, i'm going to see what dimensions I can squeeze out to keep the box as low as po…

could someone please double check these numbers. I know this box is small but that is all i have to work with and its still at the minimum.

I'm wanting to build a new enclosure for 2 12" Eclipse TI's sw-9122(tc 3HP) I currently have the in a CRX style enclosure 4ft3@35. Its in a CRX. This works well. I just want to try a different sttle enclosure. I really like the chambered t-lines Rich(stratus) from here and ROE designs. I'd like help designing a box like the one in the pciture below, its from a member on here. he did 2 separate boxes, but there CRX style sub up/port back.. so if anybody would like to give me a hand I apprecite it.. thanks, Joe

So I have my normal starting bat up front and I'm going to put an additional battery in the rear of the car near the amps. My question is should i run a fuse near the main bat to the 2nd bat as well as in between the second bat and the amp. All in all I don't think an additional fuse would hurt anything and if they power wire ever chaffed through I think I'd be really glad I had a fuse there. any help

What do you guys use to make those box blueprints?

Wondering what numbers you guys are hitting with your XCON trunk cars?

Hi I need help making a spl/daily box for 4 15s, I'm going with subs ip port back and want it to be crazy loud, I have 3500 rms going to all of them how should I make the port and what to tune it to?

Whats up guys. I am going to try to build my own box. I have only built like 2 before, but I want to give it another try. I was wondering who can I Pay to design a box for me for 2 15" Type R's... If you are interested, or have worked with these before please let me know, or send me a PM.. Thanks. Steve-o

Sooo, it is time for some ass time in my car seat tuning the system. I need music! Every genre (besides rap please). If you have links to some FLAC torrents of said media, please link me!
