I'm afraid of my port being too long.i am by no means an expert but here is what I got... 1 team fi 18v2- 1 scv 4000 a couple of extra battery's 130 amp alt stock "mechman 270 soon" big 3-dual runs of 0 through out my box whic isnt built yet is 24t-24d-44w with a slot port 22.5x6" I'm wanting to tune to 28 for lows. I want it to be fairly loud but it's no big deal if it isn't I just don't want a boomy box tuned to 40 lol. Any way with a tuning of 28 and that size box I figured around 12 cubes before port-and with the port being 46 or so inches long I'll land near 8cubes after port. which puts me near 28 hearts or so... problem is with a port that long will I run into reso…

So I had a box design done by someone that seems to be a reputable designer around the car audio forums, and I have a couple of questions about it. I have a FI BTL N2 12" D2 running on a SAZ-1500, 250amp alt, 0 ga wire throughout including big 3 and additional grounds throughout the engine compartment, XS Power d975 in the back, Optima yellow top up front. The design he gave me has a net volume of 4 cubes. Is that too big for that one sub? I told him I wanted a daily ground pounder that can kill some lows. Well it does destroy the low notes, but it seems to be pretty weak with the majority of rap/hip-hop songs, and doesn't sound real strong on rock or metal. I know the …

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?

I have been looking in to these two subs for months now reading everything I can. I am still stuck maybe some smart people can help me out. ok I am looking for high quality, clarity, accurate, punchy sound not so much loud. mainly SQ. I had two Pioneer TS-W309D4 in a sealed box at 1.15 Cu. Ft. Air Space per sub. powered by a Pyle PLA2678. I liked this sound it sounded nice punchy. but I wanted something better so this guy told me about FI and Audio Pipe amps . so then I got a FI SSD 12 with only interior leads. powered by a AUDIOPIPE APSM-1500 and in 2cu ft. of air space. tuned to 32hz ported. it got so loud my nose flap would shake and it was awesome and still …

I got some new midbass speakers and ready to mount them in the door. Problem is, there is very little depth due to the window frame directly behind the speaker mount. I had planned on making some door pods, since my panel is really flat with the pocket removed. Here is what I have to work with. Buddy told me- Hey! You have a large opening in the middle of the door. You can make a baffle, bolt it to the door, and be done! Yeah, that would be pretty easy but I think soundstage would be terrible. Here is a pic relative to postion. Am I wrong? I tried hooking up the driver and moving it around. Kinda hard to tell holding it with one hand and moving it around the door a…

I'm currently building my first 6th order bandpass enclosure. I need a way to make the top panel secure to the box, but easily removable for access to the sub once the top is put on. Here is what I have done thus far. I have also added weather stripping all around to prevent leaking. I'm looking for suggestions for the best way to go about this other than glue and screws. Thanks in advance.

Okay, so there are two ways I can go about this. In the back of a Grand Cherokee I want either 2 15s or 4 12s. I was looking at buying 2 Dual 12 aeroport boxes from Davetheboxguy. Just hooking up 4 Soundqubed HDS200s and calling it a day. OR I could design and create my own box for 2 15s (I was thinking SSA ICON or the HDS300s or perhaps the HDC 3.0) The amplifier will possibly be a BC2000d good for 2250 rms. I could step it up if need be if somebody could recommend an amp that doesn't cost much more but will give enough power. Should I go with 4 12s, or 2 15s. (Yes I know its preference but I am good with either one so help me out here) and I am going to start workin…

I plan on building a box in the near future. Which of these would be best to build with and if there is any sound difference between them? Thanks, Matt Cusack

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…

okay guys, i am lookin to build a new box for my 2 12" kicker cvr's, i am wanting around 34hz for tuning and here are the dimensions i have to work with, 39"w x 17"h x 17.5"d and plans would be great i am either looking for the port and subs facing the same direction or subs foward firing and port side firing, any plans would be nice, and i am looking for a slot port, i am not going to mess with a pipe since i dont have a hole saw, thanks in advance.

Does anyone know anything about designing a bandpass box. I have a pair of 12 w6s in a ported box w 2 6 inch areo ports tuned to 44 hz and a jl 1000/1. I can do 143.4 db at a 48-50 hz tone. Im trying to get in the uper 140s without reaching the 2500-4000 watt amplifier range. Any help on design principals or general advise on how to get louder would be greatly appreciated.

im makiing a temp system for now in my 95 grand prix. i am needing help on how much port area is ideal for these subs. going to be pushed by a alpine mrp1000 at 2 ohms. the sub is a brand new alpine type r 12. thank you for your time.

If I had (4) 6 1/2's and I went to (3) 8's, how much louder would I be?

Hey all here is a noob question that I need answered.How do I double baffle where my subs are going to be?Like do I just glue 2 peices of MDF together or do I have to do something differenet besides glue?I know this is a major noob question but I am going to be attempting to build a box for my 4 10's and I want to double baffle and flush mount where my subs are going to be and wasn't 100% sure how to do it.Thanks in advance.

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 am doing a 4th order in my GF's 1998 Mustang GT convertible. The box will be where the back seat should be since the trunk is sealed off. She has 2 db Drive K9 12"s and a db Drive A7 1,500. I want to do a 4th order bandpass with a woofers behind either seat facing into the ported wide which wiill port into thr middle. = I am thinking 1 cube each sealed with 2 each in the ported side. So 2 sealed 4 ported with 80-100^2 port tuned to 48Hz. Any thoughts?

All 3 of these can be found at Home Depot. The goals i'm looking for is the best stiffness, yet no heavier than MDF (96lbs). All sheeting would be 3\4". I read and read about these sheets and i can't get any concrete info about them... I would have also done a vs Arauco but i cannot get that around here.

Hi All, Now at my job i search McMaster-Carr very frequently. and today i decided "hey lets see what they have for sound stuff" (cause they have EVERYTHING! lol) so i did a quick search for "Sound" and found they have some nice sound barrier material and some nice sound dampening stuff, looks just like the Sound Deadener Showdown Stuff just thicker and with a backing ( http://www.sounddeadenershowdown.com/cgi-bin/index.cgi ) any ways i was just wondering if the stuff on mcmaster-carr is good sound barrier or good sound dampening?

We will be partaking in a new format this year. We have decided, after heavy heart, to drop the dB Drag format and proceed to the IASCA IdbL format. We still plan on hosting our normal 6 shows and possibly a 2x event. We are also thinking of hosting a couple night shows so that the people who have spent the money on neon will have a chance to show that off. Also we are perspectively hosting all events this year in conjunction with "Compact Evolution" which is the brainchild of Garrett Sweet. This would allow our shows to not only become stereo competition events, but car show events also. Of course, all shows will be held at The Colonial Village Fun Park again. He ha…

Looking for someone to help me design an enclosure with a kerfed port. I have been trying out doing it on scrap wood in my garage for a while and wanting to try it out on one of my enclosures. I have someone wanting an enclosure built right now and figured it would be a good one to start with. Its for 2 sundown sa8v2's in a trunk . I was told there Going to be on 1-1500 rms. . .Max dimensions - 30 wide 10 tall and 16 deep. (Ill ask if any of the dimensions can get bigger) Wanting it subs facing up and port back. Tuned in the low 30s. 30-34. . . . . Listens to mostly rap music.

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 …

Just starting an install journal here. Ive made most of the progress so far only having the trunk left to do after finishing up the install of the kicks/horns. Feel free to ask any questions. See sig. for other components in install. thats all fer now folks

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.

Any thing I should know or be wary of? 5 1/2" blade? 7 1/2"? Corded? Cordless?
