SPL & SQ / Fabrication

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.…

Hey guys, so my dad really wants an Image Dynamics 12 for Father's Day and I want to build him a box for it. It's going in a Honda CRX, and I want to try and load it off the rear hatch. I just need a simple sealed design and cut sheet. He's got 35"s between the two shock mount plastic panels and 28" from the open storage box to the back so space isn't an issue whatsoever, especially for a sealed box. Only thing important is that I want it fairly close to the 35" across so I can mount it right behind the storage tray angled back to the hatch class. Any help? Thanks a lot guys, and here are all parameters you might need http://www.imagedynamicsusa.net/files/59633398.pdf

I have a zvx12 and a sk800.1 I need box advice I want to invert it in a 2000 durango, need advice seald or ported what size box do u think I should go with any advice would be great thanks

I am looking for a box builder in the Louisville Ky area. I live in the Jefferson-town (J-Town) area (40299-3520) of Louisville Kentucky & I was wondering if any of you guys would know or recommend any box builders in the Louisville Kentucky or Southern Indiana Area. I just want someone who is good at what they do & will give me a fair price. I figure that cutting out shipping costs will save me at least $100.00 & with someone local they can actually see my car & build what I am actually looking for. Thanks Mike

i have a box all designed on sketch up, 4.2cuft tuned about 30hz. the sub will be on the rear passenger side of the cab, it will take the middle seat and the passenger seat in the rear. the sub will aim inbetween the front two seats and the port will either face towards the roof of the cab all the way to the passenger side or towards the drivers side. what would you guys do? originally i was going to face the port towards the drivers side, but if i have a passenger in the back i think it might blow their ear drum a bit... but i am sceptical about aiming it towards the roof because i dont think ill have as much air moving throughout the cab as evenly? idk.. what would you …

I been going back and forth about taking my rear seats out my crew cab silverado.The idea that i have if i remove the seats completely, is to build a enclosure/amp rack that rear passengers can still sit on and still be comfortable. I was thinking about covering both in some type foam and vinyl...have this been done before and would it work?

hey guys i have a 2006 toyota tundra access cab. currently my sub is in a 2.5cuft box tuned around 32hz. its much too small. it is being powered by a percision power black ice bk1300.1d. and i have been fiddling around on sketch up trying to make a box to fit nice and tight up against my seat in the back passenger side. the box will be roughly 4 cuft with 2 4" pvc ports. will this be enough port area for my sub? the box i have it in now has much too small of a port. i am planning to tune to around 30hz this time. sub will be roughly in the center of the two front seats firing foward, with the ports facing the drivers side. there will be one seat still usable in the rear b…

Doing my sq setup, has 2 way components 125 watts each side. Looking for a good sq sub that goes loud but good quality under $300 I will upgrade later to something higher end. So far looking at the image dynamics idq10v3. (500 watts rms) also would a sub 500 watts rms overpower the front stage? From the comps? cheers any reviews on the idq would be good too

I'm about to start building me a new box and I was thinking of bracing it like this 2x4's & 1.5" dowel rod What do you guys think?

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…

I posted this on another forum and I would like to hear the thoughts from the gurus on here as well I have been ready through pages and pages of threads on adding rear fill to help maximize the front stage. After understanding how rear fill is used for this application many folks (including myself) have been thinking how to acquire the necessary L-R. On a side not L-R seems to be the most common method although there appears to be other methods for generating a rear fill signal which require a fancy processor. The MiniDSP 2x4 has a plug-in Rear/Center Channel. This plug-in gives you the generated L-R signal, xover, 31 band eq, and up to 27ms of delay. You can al…

Ok I got my new install done which consist of 2 15 xcons facing cabin in a sealed box, ran off a crescendo BC 3500. My question is will it be a significant gain in output if I go with a ported box instead. Only reason we went sealed was shortage in trunk space given space we had enough for opt sealed enclosure. Any info?

i had a rockford fosgate t1d415 before and ive been messing around with custom boxes for a little while. i didnt know too much about winisd back then. luckily my first box i built for it played very nice and didnt have any port noise. i tuned it around 34hz if i remember correctly. i loved how low it could get down. i played into the lower/mid 20's (i know i was playing a bit lower than the tuning freq) and loved it. this time around im going to design a box for my fi sp4 15. it should be here any day (i hope) and i'd like to be tuned low. heres my current design for it. can you guys let me know if my design is ok. i know the port is a little skinny but it looks like the …

HU: Pioneer P99RS Amp for front stage: Arc Audio KS900.6 Tweets: LGP 25NFA Mids: JL Audio 4" Midbass: JL Audio 8" Amp for sub: Sundown SAZ-1500D v.3 Sub: (2) Fi Audio IB315 I think I have my front stage dialed in pretty good. My tuning includes, gain level setting, t/a, phase adjustment, rta (not relied on heavily), eq balance adjustments and crossover setting. Not in that order but those are some adjustments I made. I also meet with a MECA multi champion who was very helpful in the tuning process. The two biggest issues my setup has right now is slight smearing to the right side and I would really like the soundstage to be wider. The smearing of the center image is ver…

I need a ported sub box to around 33 Hz for an xcon .. I have 12.5 H x 32 W x 14 D to work with. I have a metal brace on the floor of my car that I need to work around. I've hit up ram design and he said he was to busy at the time , Dave the box guy never replied back .. and all the audio shop stores I go to say they can build it but the lowest tuning they can do is 60 Hz wich is bullshit. any help is greatly appreciated

Hey all, Ever wondered, what weight chop mat should I use? What resin do I need? How much hardener (MEKP) do I need to add to the resin? What is it is hot? What if it is cold? Whats the best way to use fiberglass and add strength to something? Wonder no longer my friends... As i gear up for my door pod build I have been amassing some more fiberglass fabrication products. These products are typical of what you would see in any car audio install that involves fiberglass show I wanted to share them with you, along with an explanation of each and some answers to questions I see repeatedly online! Enjoy! Also, here is a wonderful table that allows you to better un…

This is my first attempt at sealing off my trunk. With the new box forward facing, there is a gap on top that is about 1 inch in height, and gaps on ether side about 2-3 inches. What are some ideas on sealing this off completely and still look somewhat respectable? The rear deck is completely sealed off already. The only sealing that needs done is the gaps between the box and the trunk opening.

this is my first time tooling around with winisd. my fi sp4 should be here any day and i'd like to make sure my box design is okay or if i should tweak it. ive seen port velocity used frequently around here and i was wondering how i can determine port velocity. is it for aeroports only or can port velocity be determined in a L slot port? can someone explain how to find out the port velocity for a L port. and before people start saying, yes i did search around a while on the forum and google and couldnt come up with the answer. thanks!

Alright I'm looking for advice on a sub box design for an Sa-12 that will give as much SPL as possible - without sounding terribly peaky. I'm willing to compromise on Spl for a frequency curve that would be acceptable for normal music listening- hip hop, rock, and country. sub is on JX 1000/1 - if you have questions about my vehicle and setup - look on my profile first under "About Me" and then ask me if the info you want is not there. Member Quentin Jarrell said "I would build the enclosure 1.75 cubic feet net tuned to 32 hertz. This will give you a 3db ripple (boost) at 35 herts and give you a F3 (-3db) at 26 hertz. This will give you the sense of exaggerated bass …

Hey guys. New to the board here so I hope this isn't a played out topic...... but the only design I can find on SSA's site is for a single sub. Is there one floating around somewhere? The only one I could find on the net was here ----> http://www.*****.com/board/topic/158983-need-a-ported-box-design-for-2-12-ssa-dcons/ Is this a good one to try? I noticed all the youtube vids I've seen with 2 the box looks like the single enclosure design, with the port to the far side of the face. Thanks in advance.

I recently opened up a tint shop and have had a lot of customers wanting audio, so I just picked up the Sundown line. I've been an installer for 14 yrs now, but all the shops I've worked at did cookie cutter systems with pre-fab boxes so I never really learned how to make a box and match it to the subs. I've built plenty of boxes, so the actual building is not what I'm looking for it's just getting the correct size and port length I need. I see a lot of threads recommending box calculators like torres ect. which I've downloaded, but I don't see how you're converting the sub specs to box design. I found the AJ vented designer program which does this (I'm looking to built m…

Hi guys. I will have some time to hang out next week and wanted to use up all my extra MDF. I wanted to attempt to make a 4th order bandpass to put a couple PWX 10's in there and hook it up to my xbox. I know they are not subwoofers but they are my test speakers. If this box turns out good I will refine my design for a couple of real subs. This is what I have come up with. Each side chamber is 1 ft^3 sealed and the center chamber is 2 ft^3 tuned at 33hz. I have no clue how a 4th order works but this is what I have come up with. If you could explain to me how a 4th order works that might help me design this and also let me know if there is anything I can change to make my …

What makes this enclosure perform any better than a normal forth order enclosure? Or this old style. Just a forth order bandpass?

Total volume = 5.333 (1 inch MDF) Port Volume = 0.64 Tune = 31hz Box dimensions Total Box = 38 x 18 x 18 Port = 3 x 16 x 23 Is this a good design for a ported 15, or two ported 12s? If not, what needs to change? also, could the subs be mounted on the top? Would this effect quality or spl?
