SPL & SQ / Fabrication

Here is my dilema! I wanted an 18" BTL N2, BUT my malibu only has maybe 19" height in the trunk throughout. My dimensions to work with are something like 42 from wheel to wheel, 30 deep, and 19 Height. I am open to all opinions on what would be best. I REALLY want the BTL 18 but if everyone tells me 2-BTL 15s would be better I would obviously do that. I know the nightshade and SMDs like smaller boxes as well? I just bought a Sundown 2000d today sooo that will be my amp pushing w/e sub I get. I was also considering building the box out of the trunk and into the cabin therefore allowing the 18 or 2-18s to blow through the cabin in a wall type enclosure. Here are some pics …

Hope everyone had a happy and safe holiday. Alright, I want to upgrade my front stage and would like some help with speaker placement, setup, installations and whatever else you guys suggest. Check my signature for the setup I currently have. I have a lot of time before I get everything and install because I'm in Afghanistan right now. So basically I want to improve on my overall sq because my speakers are lacking in the midbass area and want to change my setup and I guess try to go active and really experience a real sq system. I'm not trying to go all out in the sq area but I want to do a 3way setup and just upgrade my setup. Any help would be greatly appreciated. Than…

Hello all, I have been a traditional sealed box kind of guy, but I want to try something different. I am going to build a bandpass box for some SA-10's that will be pushed by a SAZ-1500Dv2. The port will be pushing through a ski hole in the back seat. The sub that I have now fires through the port, but I am hoping to eliminate some of the trunk rattles by creating a port that extends through the ski pass. I have taken a few pics to give you guys an idea of what I am trying to do. I want to fire through a port where the homemade ski pass, the trunk is sealed very well, so I opted to cut a hole. I have come up with some figures for the SA-10s by using an online ca…

I was just wondering how much space between the end of the driver to the wall of the enclosure is sufficient? Meaning what wont hurt the driver or sq/ spl. I'm thinking of a 15" havoc ported. The xmax spec is 30 mm if that matters. Thanks in advance and merry Christmas to all.

I'm trying to build a box for a single FI BL 15, fully loaded. I want it tuned around 32-33 hz. Also my trunk in my car is kinda small height wise, so I was wondering if it was possible to put the sub on the top of the box and lower the height a little bit so the sub doesnt get close to the top of the trunk. The port I want on the front. Is that possible? The dimensions I have so far are: Width - 32 Height - 14 Depth - 25 Port Height - 12.5 Port Width - 5 Port Length 1 - 19.25 Port Length 2 - 8 62.5 inches Total Port Area, 3.8 ft^3 for box. Tuned at ~32. Would it be possible to put the sub on top of the box with this design, and still have the port on the front?

Ok i need some more help trying to figger out how big to make my port, it is for two sa-15's on the saz-1500d .v2 in a 97 Blazer. The box will be 19H, 38W, and 26D, subs up and port back. But i wanna put the port on the bottom centered and i was going to make the port. 6H, 20W, and 19L, but that didnt give me enuff port area and i want it somewhere between 32 to 38 or so Hz. So if someone could please help me out it would be much appreciative thanks.

I have a question regarding port length and how to measure it in my application. I have decided on one 15in FI-Q in a downfiring ported console encloser for my truck. Question is: I have attached a photo of an example I did and I don't know how to figure the length. And also, how do I figure the port area and will this be enough for a 15in FI Q. A SA-1500v.2 will power the sub. The port will be 3.5in wide and 14.5 in tall (inside diameter) but how long will it be? Looking to tune at roughly 30hz and the box will have 3.65cu after displacement if this works. Is it A, B or C. Red would be airflow Thanks in advance

I'm having trouble designing a box for the two Dreadnauts I'm getting in April. I don't know if I should have both of them in the same box or have two so they take up less space? I would like to have them in separate box's that are taller and narrow so I can still put stuff in the back of the suv. But when I try to look up the Recommended Enclosure I don't understand it. if someone could give me some pointers I would be thankful. I have never made a box before so this all new to me I will put all specs I have on the subs. Recommended Enclosure Vented (Net) Port Specs …

I'm designing a new box and have a sort of kink in my design. I'm looking to do a baffle with a 30 degree angle in it. Now the issue with this that I do not know the clearance for the sub since it will be angled downwards. It is a 15" Havoc (standard basket), and I just wanted to know if anyone had any ideas about the clearance. I basically need to know how far above the bottom of the baffle the sub needs to be to clear the bottom piece. Thanks!

Ok guys, Who wants to be first and jump in on some sketchs/layouts for me? :-) Ok here we go, I have a Fi SSD 15 on the way with a sundown 1200d But no box to put it in. So here I am, I need some help with a box layout The dimensions I have to work with are 29" wide X 31" deep X 18" Tall. If possible I think a Face up Back port would be the best for my car, But if im wrong please let me know. Thanks in advance ~Tyler

http://www.craftsman.com/shc/s/p_10155_12602_00964473000P I found one of these at a local pawn shop and was wondering if it would be worth picking up for 50 bucks. The one at the shop has a attachment that looks something like a router and has a circle cutting attachment among other things. Really would just need it for cutting circles, and then possibly other household things. Sorry if this is in the wrong section didnt really know where to ask about tools here.

have an 18" aa havoc and it's going into a 98 pontiac bonneville....want to build a ported box inside the trunk but i don't really know where to begin....the box has to be 6.0 cubic feet after displacement and tuned between 28-30 hz. thanks

I will be installing a budget audio system in my 2008 Hyundai Elantra four door. I will be running a three way front stage. I am using Viper Audio 650.2 passive component set. They are metal dome tweeters with 6.5" midrange and crossovers. The tweets are harsh and the 6.5's lack midbass. I picked them up bnib cheap.... I will be using a Boss REV-665 four channel for power. Again got the amp cheap..... Channel 1&2 for the component set and channel 3&4 for 6.5" woofers. Mounting: tweeters in A-pillars aimed at each other, 6.5's midrange in custom kick panels aimed at dome light, 6.5 woofer in bottom of front doors mounted behind factory door panels and aimed at each…

Ok in the cargo area I got 38Wx20Dx22H. Was gonna only have it 20" high but bumped it up a lilttle to get as much box space as available. According to a box calculator on the12volt.com puts me at 8.01cf, figure about 7.5 after sub displacement (i think thats about right). I tried figuring out for ports and when I put in a 4" aeroport tuned to 32Hz put it at only 1.5" in length.....this does not seem right to me. I tried figuring out for a slot port at 4"x18.5" tuned at 32Hz put the length at 18.9". A 2"x18.5" slot only comes out to 8" of length. Does all this seem right? Tried to mock something up in google sketch but I failed pretty hard at that. If I can't figure thi…

After searching for a subwoofer I have decided on the DCON 12" it seems perfect for what I am looking for. My question is regarding the box I saw the recommended plans were 2.25^3 at 30hz I think but I have plans already for a 2.5^3 box tuned for 35hz. Would the sub work well in that box or should I scrap it and just build the recommended one. I also have a 350 watt alpine amp, would it be ok to run the dcon at 350 watts? Thanks in advance for any advice/help. - Alex

After doing the math i come up with a .825 cubic foot enclosure which doesn't seem to leave me with room for ports. Can someone help me out here please? What should my internal volume be? I used the box calculator at the12volt.com, is there a different calculator I should be using? Thank You to anyone who can help me.

Ok, I just want to know some of your guys experiences with t-nuts or huricain nuts, wich ones hold better? The screws I am using are not holding well in mdf so I need to get somthing stronger

Well, a buddy of mine has one of these, it's a single cab, long bed. He just got a new, sweet ass small block 350 in it, sounds mean. But his audio, just makes me want to cry.. Stock 28 year OLD 5x7's in the rear, if what he told me is right, and it has no front speakers, doors or top of dash. Well, I told him I could fabricate him some 6.5's into his doors, there's plenty of space, and I was just wondering how would I do the wiring since it doesn't have any power options in the doors what so ever. So what I'm asking, do I drill a hole into the side of the door near the inside of truck and vise versa and find some rubber grommets or what? Thanks for helping!

I need some help would u guys recommend a figerglass box and mdf or jus an mdf box I don't know much about mdf an fiberglass boxes it's for an 18" btl

Hello, I am building a box for a friend and I had my MDF all ready to cut, measured out panels and everything and he calls and tells me that he want an aeroported box. I have searched and read different things in this section and after figuring out slot is actually a lot more different than aero ported, I just don't get it. So, I have come for some box designing help. Dimensions: Depth: 16 Height: 16 Width: 40 It is for an Fi X 12. Was hoping for 2.0ft^3 at 32hz I really just need to know how many flared aeroports I would need with no port noise. Diameter and Length of the aeroport would be nice. Thanks in advanced, Jay

I'm planning on securing my sub box to my trunk using L brackets. I'm also putting in a plywood floor so I can mount amps/batteries/etc to it also. But my question is that, when using the L brackets on the box, do I just bolt straight through the side of the box? And if I ever move the box to another vehicle or change the arrangement, it will have a handful of holes in the side? Just seems odd. Is this the right was to do it though?

I have the Morel Dotech Ovation 6 two way set and was wondering if I could still use them to go three way sometime next year. I actually was thinking of using the Selenium 6 inch midwoofers as midrange or should I just get another midrange for this? I actually was told to use the Morel midrange but some say go with Hertz Audio midrange. What you folks think and I am going active with this in the future. Thank you.

If I have a box that is 36" wide by 22" deep by 24" tall how big would I want my port for tuning it to 32hz? Its for an 18" n2
