SPL & SQ / Fabrication

On the Termlab im hitting a 144.3 sealed up at the dash with a sweep. its in a trunked cavalier. i just want to know if i can get that score a little bit higher? would holding the trunk lid, sunroof, or doors down during a run help? would more room for air to get into the cabin help? does subwoofer box placement help, meaning how far away from the trunk lid it is, also how about rear seat folded down half way help? how about front seat positions? kind of just trying to get as much of an edge as i can. with the 144.3 run it was all set up for daily driving, not much tuning done at all, as in i didnt play with box position, or seat position or anything like that. i just k…

im lookin to start a new build and try doing a wall. i know i shouldnt be doing this myself but the only way to learn it to ask a ton of questions and do it yourself. im not sure on the best/proper way to safely secure a wall. the walls gonna be for 2 psi platform 3s which arent too light. i just dont want the wall crushing me if i ever get into an accident. thanks.

My lil ass will be there with my bro from Tallahassee...just booked hotel and plane tickets. see he just busted a 159.5 Shane? Like 5th in the USA (SS1-2)..hell yea! more free chit!

Last 4 years and last 7 boxes I have all used slot ports. I have never even looked into aeros before so I got a few questions and would like some support on what others have told me about them. As of right now I am using the torez calculator to try to help me with this. The box Im designing is for a 21 warden, I would like to have 115+ sq in of port for it tuned to low 30s. I have been told that flared ports somehow equal a bigger straight port, example I was told that a 6in flare would equal a 9in straight port. Im guessing the torez calculator goes by straight ports that are not flared. I am getting confused with all the diff info I have been given and would like any ki…

I might be doing an install with a clarion DRZ9255 with a active setup on the HAT L1's .. wondering how accurate the built in crossover is on the clarion if anyone here has used it in this fashion

I have a phoenix gold ti 12d and i'm wanting to build a 2.75 cu/ft SQ box tuned to 25hz. which are the specs. that site recommends for it. i have a mtx te 1501d that will be powering the sub in my 08 4dr toyota tacoma. i'm not the greatest with math and formulas so any help to make this buildup as painless as possible would be great. thank you

i need a box build for my sa-10's

Hey all.I have a few questions about walls for car audio in cars.I have wanted a wall ever since i got into car audio but ive had a few concerns about them.Here are a couple of questions/concerns I have about them. 1.About how much does a wall weigh on average? ( I was told i could get a wall built in my car that would weigh about 300lbs made of birchwood.Is that possible?) 2.Is it a must to have air shock or whatever in the rear of the car (I have a 2001 Mitsubishi Galant ES 2.4L and it would cost over a grand to put airshocks in.) 3.Do you guys think my car could handle the weight of a wall? i VERY BADLY want a wall in my car and I know I will not stop fiddling with my …

Hey guys just need some advice here. I have a 98 Dodge Ram Extended cab and plan to install a BTL 18 in the back. The seat will come out and I have ample room for enclosure. I just want to know if anyone else has done this kind of install in a similar truck and I basically want to know if the FI specs for box will be the best, maybe someone else has found something that works better. I have an Exile X2400.1 that is going to push it. I listen to mainly rap music and I want that sucker to pound. I already performed big 3 upgrade and have cap ready to go, my truck is diesel so I have 2 batteries already. I figured FI's specs for enclosure are on the money just looking to see…

this is my plan. im building a box that has 4 nightshade 15s. i designed the box on a 3d program to scale. the box is 19.5 cubes. the port is 7inches wide and 38.5 inches tall. that gives me 269.5^2 inches of port area and i need 12-16^2 inches of port area for each cube of airspace. so ill make the port area requirement. the box is tuned to 30hz. i will also be having all the walls 1.5inches thick. everything will be liguid nailed and screwed together.what you guys think? i cant seem to get the pictures to upload. i dont know how to get it from google sketchup to a image hosting site. any help with this?

Way late but as promised here are a few pics, sorry it took so long and even if you don't know it all you guys on the forum have helped me in some way or another. The idea was to obviously keep a sub inside the car (like my 8's that were in there before) those of you who know BMW trunks understand why. Keeping it stealth was a main focus hence the flat black paint it really blends it into the car. Any and all comments are welcome, keep in mind I designed it to be way stiff, sound great, and astetics came in last. I estimate that it is around 1.2 net after polyfill. I set it on top of my 1.5 cu ft net box and it was fairly close. Later, b

where did it go!?!?!?

ok my friend will build me a box in his wood shop but i need to get him plans. SI 15 MAG, ported. what do you think of the aeroports? is it worth it for only $25 extra? most people use 2 of them at $12 each. power will be a hifonics ZEUS 1000D 1000@1ohm it is a lexus 2002 es300. should be the same as the new camrey. people have put 2 15 in there before with a almsot bent box. i only need 1. the red strap is what i will be using to hold the sub in place, i would also love there to be ehough room to put my trunk battey next to the box. it is 6.5 inches wide demetions are THANKS FOR ALL THE HELP I AM FINALLY BUYING A SUB TO FINISH MY AUDIO SYSTEM AFTER 2 YEARS!!!!!

i just had my wood cut from lowes (they did a bad job cutting) and i was wonder what size screws should i use to put the together? i dont have a router so what else could i use to cut the hole out for my sub? i have some titebond wood glue and some heavy duty liquid nails here.

Well, i didnt think this was going to end up happening but i actually saw an Fi BTL N2 18" For $400 in my city. I was previously going to get a 15" Fi Q or BL which was going to cost me $400 shipped anyways so i cant give up this opportunity. Now in the quest for less trunk rattle, i wanted to fire my subwoofers forward into the cabin, BUT i dont have foldable seats. OhJay gave me a good idea. Use external aeroports that go through the rear deck where the 6x9 speakers go. I thought it was a great idea, something a bit different. Now i was wondering if any of you could make it happen. Iv got probably 19 inches maximum of height, probably about 40 inches of width. I…

I Recently Talked to Chad Kyupers Drivers Start Shipping a week from today. While talking to him i mentioned 6cuft@29Hz, he said he had a guy do 4.5 at 30Hz and its output was INSANE with only 800w. he said 6@29 with 1200w should wang hard so im down to 2 enclosure options, both with equal port area (77sqin) only one iwth 2 ports and one with one. originally i though there was going to be no way to get the ports on the same plain as the driver, so i designed a side firing enclosure and the port a straight shot. then i came up with the idea to get the port on the same plain... see image below http://i11.photobucket.com/albums/a167/CBFryman2/avatest.bmp the bottom thing…

alright so I will start building a sub box pretty soon but I have an issue, there is a metal brace on the floor of my car going from one side to the other. can I work around it? or does the box have to be flat one all sides?

Okay, from what ive read over the past few weeks ive decided that i want to go with an active frontstage. My DEH-7800MP is capable of this from what ive read. I plan on glassing the front doors to accept a well acoustically matched woofer and tweeter combo, i was hoping someone here could give me some suggestions on what woofer and tweeter to use so that i have little flatspots in my sound. Also for reference i hate harsh pingy tweeters, i don't particularly like all my highs to sound like crashing symbols! lol.... With switching to an active front stage this also means i will be completely losing my rear audio am i correct? Thats the only thing ive been confused about! T…

About to start the new enclosure for my 2 zcon 12s. It will be a trunk wall. I will be trying a 10 inch round port this time. I'm wondering how many cubic feet you guys think I should aim for with the new enclosure? ? Will have an aq3500 at .5 on them but Will be adding another 3500 as soon as I can find another. . Going to be tuning around 33-34. any suggestions?

Anyone wants to donate some blueprint of boxes that could fit here sub is 9515 w/ strapped saz1500 amp Length - 31.5 inches Height - 18 inches Depth - 22 inches These measurements are the space left to be exact, no box yet. Assuming 1inch MDF will be used and I'm eyeing for 4.5cu.ft. or 5cubes plus port tuned to 40-42hz. Sub is facing up and port is facing the rear hatch door. With the given depth, there's a 4inch gap remaining before the box/port would hit the rear hatch. Id appreciate your suggestions. Thanks

I'm going to be putting together a new box this weekend for a 10'' BL in my reg cab ranger. First off, the box will be 1.6@36-37 with (2) 3'' aeroports (Fi recommends 1.25). Will I run into any problems with having the box larger than optimal size? How should I put my ports? Here's the space I'm working with: Option 1: Option 2: Option 3:
