What i want is the box to be smooth, without being able to see the screws so i can paint the box and have it look very smooth. I have to ways im thinking of going about this. 1- This is the one i feel as the better of the two....sink the screws a little further into the mdf and put a filler then sand it smooth or 2- After the box glue has dried take the screw out then use a filler and sand? Is there any reason for the screws to stay in the wood or can i take them back out? Thanks, Jack3d

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!

i would like to congradulate chris and rick for going to finals. and placing 10th in the world for ss1-2. it's good to see someone from up here to actually make it. now lets see what they are going to do next year. saggs

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.

I want to build a sealed box behind the back seat of my 08 Dakota Crew Cab. There is VERY little space back there, to the point that to get my airspace, I need to get rid of the back wall of the box. My idea is to use some damplifier pro or spectru sludge on the cab wall to create the back wall of the enclosure. Am I on the right track? Or is there a better way to do this. This is the only location I can use, due to restrictions from my wife. Thanks Rob

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 will be building a box for 2 Sundown E 15s. The subs are dual 4ohm going to wire them to 1ohm on a audiopipe AP10001D. So they will be gettin a little more than rms wattage but I dont see that being a problem. Thats where i need help. I know on Sundowns website they recommend ported 3.0-4.0ft^3 @ 35 hz. What would yall recommend on box size and hz since i will be overpowering a little. Subs are going in a 2005 Silverado crew cab z71. I have the 60/40 sectioned backseat. I will possibly removing the 60 part for box. So pretty much what i need to know is that: ft^3 size/hz level SIngle chamber or dual? Daily application not sure on dimensions of section on backseat but i …

So I am stuck, cannot decide what to do or which direction to even go at this point, need some assistance and I will try to make this short as to avoid the TLDR syndrome. To start off here is what I have currently in the vehicle (a 2009 Honda Fit), (2) Sundown SA 12’s wired to 1ohm on a SAZ1500D. They currently sit in a ported box that is 20”Hx31”Wx16”D, with (3) 4” aero ports 12” long, yielding a box of 4cuft net, tuned at 38Hz subs up port back. While this has been the loudest box I have built, it’s not the only one. I built another 17”x39.5”x16” with (1) 6” aero port tuned at 34Hz sub/port up, and finally another with the same dimensions however this last one was a slo…

ok im making my first attempt at a custom box. its for 1 sd12 in the trunk of a honda accord planing on sub facing back and ports facing up to go through the rear deck. plywood (no mdf at local building store) 3/4 inch depth 18" w 20" h 14" port (1) L 12" dia.3 if my calculations are right box is 2.21 ft3 tuned to 34.15 sub displacement is .10 so that should net me a 2.11ft3 box (damn i hate math) am i anywhere close? or even headed in the right direction? any input would be great cause right now its in a cookie cutter Q-logic box (1.5 ported and its starving for air) thanks guys and gals

What do you guys think of this design? The huge ported section will be roughly 50 width, 36 Height, and 36 length all the way up to the back of my front seats. The sealed section in the trunk will have roughly 1.5-2 cubes per sub with the ported having over 30 cubes hopefully Give me your opinions of this design please Thanks http://img573.imageshack.us/img573/9628/boxdesign3.png http://img341.imageshack.us/img341/570/boxdesign.png http://img29.imageshack.us/img29/7765/boxdesign2.png does that make sense?

New JBL W12GTi MKII waiting for a home. Need to do sealed as space is limited but plenty to work with for a proper enclosure. Looking for it to attack the lows and have a flat(ish) response. Not a ground pounder, rather a SQ build for this old man.

I plan on doing some dynamat here soon, would it be worth also filling my panels and/or doors with polyfil? What effects will it have?

some people know that I want to switch my blazer over to sq after I get a car for bass race/db drag so here is what I have so far let me know what you think mids amp (2ohms) http://www.woofersetc.com/p6743/PCX2125--P...t-Amplifier.htm tweeter amp (2ohms) http://www.woofersetc.com/p6743/PCX2125--P...t-Amplifier.htm sub amp (at 1.5ohms) http://ampguts.realmofexcursion.com/DD_Z1/ head unit ( I have just wanted to try it) http://www.woofersetc.com/p6576/CD7200-mkI...CD-receiver.htm mids for dash http://www.woofersetc.com/p1564/ES400--CDT...;-Midranges.htm mids for door http://www.woofersetc.com/p1566/ES600--CDT...;-Midranges.htm tweeters (a pillar mounted) http://www.wooferse…

for thoes who have compeated in iasca or usac sq the question i have is where should the center of the stage be in the car. my personal prefrence is center of the steering wheel. i want to know if it should be right in front of you in front of the steering wheel or the center of the dash as you would need to look at the middle of the dash to imagin thats where the voices are coming from. which is the correct answer for competition i am runing 3way active and have time alignment to play with

I've recently wanted to start making a horn style box, I've build one on accident before, but didnt know it was a horn box. Now im just needing some advice or basic tips on building and tuning of them.

Hey all.I was wondering if my port is to close to my rear hatch.My friends and I both seem to think my system should be louder and I seem to think that it might be my port being to close to my rear hatch and not having enough room to breathe.My system consists of a DC 5k and 4 10" DC lvl 3 m2 subs with the level 4 upgrades.My enclosure was made by DC Creations and is 4.5 cubes after displacments (I believe) and tuned to 33hz.Here is a pic of what im talking about with the port.I can take a better pic if need be.So what im wondering is if I flip the box around with the port facing into the cabin instead of towards the hatch,would it help out any or would a enclosure with s…

here we go Here you go. more to come Later

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

I'm redoing my box for 3-10" (or 3-12" not sure yet). Now currently my port is down low facing the dash. The current box is a TON louder with all the windows down vs up. I know this is normal sometime, but I don't like driving around disturbing everyone with them down, lol. So I was wondering if moving the port would help or make a difference? Port up with the subs, port back towards the back wall of the truck, or try it again with the new box faceing towards the dash again? Just an idea of what it looks like at this time. You can see the "box" at the bottom. It's an "semi-external" with 8" outside & 4" inside to save some space.

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…

http://www.woofersetc.com/index.cfm?fuseac...Product_ID=3637 or because the specs of the tc-7 are here http://tcsounds.com/tc7.htm http://www.woofersetc.com/index.cfm?fuseac...Product_ID=4450 this would work for the large ported box under low extension so pretty much the first ported at 1cu a chamber the obcon in the picture at 1.4 a chamber or the large ported for 1.7 a chamber which would give me low extention i waned 12's but they would be to big for my hatch. i listen to rap and have a small 2002 civic si hachback. and i want a quality system, but the thing is that because these are 10's i am afraid they wont get loud enough the power will be from this Hifonics BXi …
