hey im putting 4 l5 15's into my van but was wondering iwhich way i would be louder, if i had 2000 watts going to all 4 so it would b 500 a piece or just do 2000 and only hook up two for 1000 watts a piece , in my spl class for this year i cant exceed 2000 watts

I'll soon be picking up a second Skar VVX which leaves me to a new box build (: It'll be going in the rear cargo area of a 99 Jeep Grand Cherokee I'd did it tuned somewhere around 33-34Hz and about 5 cubes after displacement Subs up and port back Will be using 3/4 mdf and the top will be a double baffle (2 3/4 pieces) and the subs will be countersunk will be building an amp rack off the back (so facing the front of the car) but that really isnt part of the box design Max dim are 40 wide 25 deep and 20 tall, (pref 15 tall though) Everything I will be running is 2 Skar VVX 15's D4 wired to 1 ohm Concept HPN-1500 (clamped clean at 1100) Big 3 upgrade (to be done when i buil…

Me and smokedog will be hosting a show in bluefield wv at an autozone. We will have it at the end of sept. To space it out from the other shows thats happening up here so we dont get burnt out on it. Spl will have 5 classes still and we are gonna do sq as well. Door prizes will be supplied by Autozone, it should be a blast. But spl and sq will be happening at this show.

So was wondering if this box design was good for spl( stole the pic from smd froum ) http://i1352.photobucket.com/albums/q641/antoinez28/1571462d541ddd32176d702a8041523f_zps241afbf8.jpg The only thing I will be using 3/4 mdf and the top of the box will be 2 inch thick plus bracing.

Alright guys, here it is. Not too bad for my first time I think. PS. This is on completely Stock electrical (other than a cap) and we all know how well caps help you out and only 1.5k wrms. Music Peak: Test Tone: ~48hz

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

I am new and am designing a ported box, it is 4.1 cubed inside for 1 15 and i want to tune low. how big should the port be so the air speed is not too fast?

Hey everyone. What do you think would be the best for music and spl box size for a 15" Zcon. Been looking but can't find the suggested box sizes on here. Thanks guys.

Hey guys this is my first post! Seems like a great forum with knowledgeable members, so anyways... What is the best stuff to seal an enclosure with? Silicone? Caulking? Which type?

So I got this 30$ subwoofer which I bought 3 year ago and it still plays good and I like it. But the box what it has now I was told is too small and tuned very high(indeed it does not hit the lows very good). I have no information about its xmas, vas, FS ... etc. It says 900W max (maybe 150w real ) 12 inch Thunder. Model BC1250RD I want something to listen to my music till I get money for NSv2 ( rap and some bass tests... so low tuning around 34Hz). Here are some pics. My fail box. Yes I know I don't need polyfill for a ported box. Port is 4.7 inches radius , long around 5-6 inches. So help me forum. I was told by a pro I should go with 2 - 2.25 cub ft , 15 sq inch r…

So here is the story. I finally have all of the stuff I need to install my saz2500d. Took box out, 4.75^3. Big for my s-10 3 door. Basically an extended cab with a door. Have the zcon's ready to drop in. Put empty box back in to see where I could put my amp and this is where I run into a problem. Box goes from floor to 2" below back window. From driver side door to 5-6" from other side. With subs installed there is 12" of room on top of box. Amp would hang over about 5" or so. The port is on the passenger bottom. If I mount it on the box overhanging the open port side, would that be a problem? What about mounting it inside the box? The port is 20" wide and 24" long. Plent…

So I'm in the Midwestspl local and I'm going to change my class to nationals and was wondering if any body on here is from the same group "Midwestspl" that in the basic 4 class that can tell me how tall my box can be I know it to the window line but my 2005 tahoe has to different window line heights the side window is higher than the back hatch window...more ? To come once that one is answer.

I decided on a vehicle, and am just waiting for my check; In the mean time, I have some money set aside to start on the system in the new truck. So far i've decided on the equipment for the front stage (Zed and Crescendo speakers) just not how many lol. I think $1250-1500 is fair for a setup; and that's what i'll put towards the subs. (tax money will pay for the front stage ) My goal is as loud as possible below 40hz. I sold my BTL this morning, bittersweet, I only got to enjoy it for a few days before losing my truck But the new plan is a bunch of obsidians on a hifonics BRX 2400. I'm thinking four 18's, 24cubes @ 30hz. That is about half the budget there, plus…

My current front stage has visible speakers in the a-pillars and kick panels. Imaging is great, sound stage is deep/wide and often outside the vehicle. I have wondered what it would sound like if the speakers were hidden. Would the sound stage be wider, deeper and even more transparent because I would not be able to visibly localize the speakers? I stumbled across The McGurk Effect. Just to give you an idea of how visible my front stage is. Hmmm..... time to start re-making a-pillars for a hidden install? And carpet over kicks?

I have been searching around and just can't seem to get a good enough grasp on these so hopefully somebody here can help me. I'm building a box so after the displacement of everything it will be 3cuft. I will be running two Audioque HDC310s D1 and want to tune the box to 35 hz. So my question is how many ports? How long? What diameter? I just don't want to screw this up and have port noise or inefficient ports. I was also wondering if I could just get pvc pipe from a local hardware store and use that and buy some flares online to save some money. Thanks in advance!

In the back of my escape there is little room, especially with the rear strut towers protruding about four inches out each side. The space I have to work with is as follows: 40" wide, 24" deep on top, 32" deep on the bottom. which comes out to be about 10 cubes. The height is what can move, although 18" is ideal. I'd like to keep the box rectangular but if I have to make the back slanted for space that's fine. I want the box to be ported but I have very little room. What type of port should I use and will this work for two 18's? Brand is yet to be determined, I'm still in the planning stage.

guys i have an idea i want to do a new enclosure in the trunk of my 1995 caprice i was thinking of building 2 boxes one on the left side of the trunk facing inward and the other on the right side facing inward as well the boxes will be built to specs and ported for my db drive k915d4s powered by a bc3500d i also plan on cutting out the area behinfd the arm rest in the center of my back seat to act as a port into the cabin thid setup is for spl only but be used as a daily driver what do you guys tthink as fsr as the perfomance aspect of tis desighn there will be a total of 4 subs 2 on each side withe aproxamatley 10-15 inches between the boxes or less tips and feed back n…

I am looking to do 1.5 ft3 with a slot port. I am thinking 20x14.25x12.5 with a .5 wide port by 9.8 inch. For the slot is it as easy as it seems just make 13.75 x 9.8 and keep it a half inch off the side wall?

I have a single ported kicker CVX 12" in a custom box which I built, IT sounds nice. It is powered by a kicker 750.1. The box is tuned to 34hz i believe and is 2.25 cubes. The audio is nice, a nice mix between power and quality, the way I like. But Im looking to go bigger which is difficult because I have a volvo. I came upon an AMAZING deal. I am getting TWO kicker L7's and a 1500.1 kicker amp. Each L7 requires 3.23 cubes ported I believe. THER IS NO ROOM FOR TWO PORTED IN MY TRUNCK. But each one only uses 2 cubes sealed. MY QUESTION IS: Would I get more sound (louder) with one CVX 12 ported @ 750w OR would I get more sound (louder) with two SEALED L7's @ 1500w? I KNOW s…

the back window on my 2000 ford Explorer is Mage Flexxing !!! what can be done to stop the spl from leaking out ???

i have a 89 chevy 1500 standard cab and am tryin to design a box that will fit behind the seat. Anybody on here have any expericence with these vehicles and enclosures like this?

I want to run a Fi Q 18" off an saz-1500d in my new project, a 95 eldorado. I want to put it in the trunk. My trunk isn't tall enough to fire an 18 back so it'll have to fire up. I'm getting rid of the rear 6x9's, so I was thinking sub in the middle of the box firing up and a round port on either side firing into the empty speaker holes in the back deck. Box dimensions would be 38wide, 16.75tall with double baffle and 24 deep. Winisd is saying to tune 6.5 cu ft to 28hz i need two 4" round ports 10.15" long. That's .073 cu ft each. Or .015 total, and .24 for the sub. So .39 off 6.9 cu ft, giving me a net of 6.5 cu ft. Should the ports be flush with the top of the box, or …

My goal this yr. is farely ambitious. I want to post the loudest Trunk score in DBDrag. This is not gonna be an easy task by no means. Thier are some seriously big shoes to fill following in the likes of Dave Dasilva, Mike Stiers, Don Doyle, Steve Sears to name a few. I will have to achieve at least 154+ to achieve my goal. My starting point See ya in the Lanes

I have a 95 extended cab Silverado that I want to put a decent sounding system in. Nothing radical, just decent. The enclosure will be going under the back seat and the best i can figure I will only have ~2 cu ft to work with. The box could be 60"+ long but only ~14" deep and 4"(back) x9"(front) tall with a considerable section (21") that would be much more shallow across the hump. I was pretty discouraged when i measured my dimensions. I don't think i can raise the seat as it's mounted to the sides of the cab. My options are wide open. I am willing to do anything from 8s to a single 12" (doubtful). I'm not sure I can make a ported design work but I guess it's possible.…
