SPL & SQ / Fabrication

got my iCONs in, and im starting a few enclosures.. problem is, im not sure what kind of airspace is optimal.. id rather build 1 or 2 boxes and play with the tuning rather then ad to my collection of T&E boxes.. hoop of the trunk is unbelievably small, so the box might be split into 2 boxes.. ive got a few solid ideas for boxes that have measured out to 2.5 each sub.. should i be shooting for over 3.0??? from DevilDriver's review it seems the subs like the biggest possible enclosure.. il post pics in a few

Looking for some tips on the trunk set-up. I have an 18" BL in there currently that is upfiring as it is the only arrangement I could use and still get it in the trunk. I'm looking at switching to a 15" though and can change it around if you guys have tried anything that works well. Firing into seats, firing back, port arrangement. stuff like that that I was unable to with the 18". Looking to save some time before I start tuning!! maybe you guys have had some good tips for me to start with. Any other good trunk tips would be appreciated to. If I compete with this in my car, it'll be a first. I've typically only competed with hatchbacks

Gettin ready to start on a new build. Will consist of: 15" Sundown Nightshade D2 Alphasonik 1000HCA (Possibly saz1500) All 1/0 Exide Orbital Deep Cycle Damplifier Pro will be installed on all doors and on hatch and on the floor from the back seats back. I have more for rest of truck but probably wont have time to get it all on at first. I want to be able to put up some good numbers on the TL so what kind of design you got for me? Should I do a slot port or aero? About what size box and tuned to what? Thanks 3 cu ft tuned to 36hz with 3 4" flares?

Hi I am doing my best to avoid stupid pointless purchases with my summer build however the box Ive had built did not pass your guys inspection http://www.soundsolutionsaudio.com/forum/topic/58341-please-help-me-figure-out-port-tuning-did-i-get-screwed/ Current box: 34W X 14H X 24D outer dimensions Port: 4W X 12.5H X 12D (no L) (2) DD 2512C on (2) hifonics brz1200 @ 1ohm ea the only difference with the pics in the link above is that I have removed the slanted port divider I'm wondering if a "better" box would be the way to go I have no reason to think the box is performing poorly I'm currently on a mission for more power but Ive got alot of responses to my amp bu…

this is the box i decided to make for my 2 sa12's am i ready to cut it out or is there anything else i need to do? and does the cut list take the port into account? or is that a separate cut?

My plan is to use 3 fans as a just in case precaution the way how i am making my new floor in my car to house my amps. I will be contacting a couple companies tomorrow but before that time comes, lets see if anyone knows this- Can pc case fans be used in my car? I ask this because of the following- All these case fans i'm looking at are rated as follows- Rated voltage= 12v Starting voltage= 6v (there is only 2 lines on the fan, +12v and -12v so 6v gots me lost... Anyways, i do not know the voltage tolerance of pc case fans... My voltage runs at 14.9v. PSUs typically are set to a max of 10% + or - on any voltage line before they shut down. This means a pc fan could never …

i know pretty much nothing about mids and highs just to throw that out there. Is there a big enough difference between running mids/highs on 2 ohms vs 4 ohms that is actually worth sacrificing the power to run @ 4 ohms? or is 2 ohms going to be good enough for a daily driver? edit: by the way if anyone has a good place to educate myself on mids/highs that would be greatly appreciated.

Ok, well I just got a newer vehicle (2001 chevy tahoe). After spending my limit to upgrade my substage, I had my alpine 9831 from about 2-3 years ago die on me. I am thinking I'll get a cda-9887 to replace is since it will be pretty much a drop in change, and I can save some of my older cables. I'm really not that happy with the eq it has, so I'm considering adding one in there. I've never done this before, and while I've been researching it everyone has a different opinion as to what I should look for, so any suggestions will be appreciated. I have been considering adding 2 sets of 6.5 components up front, so I can keep my factory look without a large pod sticking out f…

so in a month or 2 i will be starting on my rebuild to run 2 old style XXX15's, 2 sundown saz-1500d's and other goodies i haven't decided yet(sound deading, comps and such). well, what my plan is on running these is to seal my trunk off from the cabin. for the box i want to forward fire it along with the port. from where i see it the baffle will sit 2-3 inches from the rear seat opening. the trunk space i have available is 40" wide, 17" tall, and about 29" deep. though for the size enclosure I'm going for about 6cu before displacement. i believe i have about 8-9cu before displacement total. here is a quick sketch i drew up on a graph paper. each cube length stands for 1" …

On bandpass enclosures, specifically 4th order for the moment, but I will be messing with 6th order later. I am always re-reading the diysubwoofers page. If anyone can reccomend books, sites, etc.... it would be great. Also an general rules of thumb too.

What is box impediance rise and how is it calculated.

Hey all.Ive decidied since my trunk is so small im going to do what ive always wanted to do.Wall my car.I have a 2001 galant and was wondering if it would be worth the money to wall it.I will use my 2 15" american bass xfl subs and my planet audio bb2 2400rms.I have a friend thats saying it wouldnt be worth walling because its not a hatchback car.So is he correct or would it be worth it? I will do some competing but I mainly want to be as louad as possible on music.

I am just wondering a little about amplifers and competition...... this makes me think because the wattage output of amplifers on the normal consumer market, is growing exponentially fast, for example a few years ago the Earthquake D2 was one of only a few amplifers that could be had for a not so bad price and was doing well over 2000 watts.... I am curious more about this in the purpose of street classes where 12volts and only one battery is allowed now Orion, Kicker, Hifonics, MMATS, PowerBass, American Bass, SPL Dynamics, Harrison Labs, Tru Technologies, Phoenix Gold, Zapco, Cadence, Rockford Fosgate, US Amps (the list goes way on) all make or sell a amplifer model tha…

http://cgi.ebay.com/4-0-CU-FT-CUSTOM-PORTED-BOX-fits-KICKER-CVR15-CVX15-/160554332666?pt=LH_DefaultDomain_0&hash=item2561c8b1fa It would be going with a Sundown nightshade. I am very curious to hear what you have to say about this, being that its from ebay. But 4.0 CU. Ft. tuned to 32 hz seem perfect. I know building one will be a little cheaper but it probably wont come out as nice and would save me the headache of building one myself. But if you recommended that I just build one myself then thats what ill do.

Hey I need to. Build a new box. I have mangled one of my subs so I need to down grade to one sub. I'm wondering if anyone has Term-pak. I just need a basic box 2.5 cu/f with big port tuned 31htz if someone could run the numbers for me it would be greatly appreciated. I really miss my bass.

I started to notice my sub was sounding a little weird today, so i check my box to make sure everything was ok, but it wasnt! i must have a leak in my trunk seal, because my box was soaked with water. booo. but anyways, i will be building a new box after i fix the leaks, and i need some advice on a different box setup. MY box was about 5 cubes after sub and brace displacement, tuned to 27hz. (sub/port back). I wasnt really impressed with the output at lower frequencies, and the overall output from the setup. (ss rl-p 18, aq2200d) Can anyone suggest a different design that can maximize the overall output? It's in a 1990 lincoln towncar. Thanks!

I want to know how to design my own bandpass enclosure. Can anyone link me to something to read? i wanna do 18s in my cut through but the box is going to have to be bandpass as my opening is only about 10x40. and i dont want someone to just design me one. i wanna know why the sealed chamber has to be this big and why the ported chamber has to that big and how to tune them and what not. i know its not an easy thing to grasp but you had to start somewhere... how are you guys designing them?

Help Please. I want to build a ported box for 4 FI 15" BTL's Currently I have a 9 Cuft box with 2 FI 15" BTL's. Each sub in it's own enclosure. FI suggests 3-5 Cuft per sub. Can I make just one box for all 4 with one port? Or do I make a box that seperates all 4 or two? I like the sound with 4.5 Cuft per sub. I am also lost on the port area if I make one 18 Cuft box for all 4. Really appreciate your suggestions here. Thanks, JR

Im designing my wall for two 18 zcons. Going in an 87 dodge colt lol will have them wired to .7 on an audioque 3500.1. upgrading to a 5k or 7k in near future so keep that in mind. so far i figure I will have 14 ft3 for my subs after all displacements. so 7 cubes each My port will be 197 sq in tuned to 34. will be 5.5" x 35 3/4" roughly 14 sq in per foot. Am i building the box too big? since i plan on upgrading to bigger power should i go smaller? also give opinions on port size and tuning. or do i stop asking questions and just get it done and find out lol

any body have it its impossible to find

Vehicle: toyota camry 1999 Location: trunk firing forward Space: 39w 14t 25d available Subs: 2 ssa gcon 10s Slot port Music : rap , rock Goal: everyday box Tuning : 33 hz ? Volume 2.5 to 3.0 cu. ft.?

Im tired of my setup so i sold my 4 15's but now im stuck with the box..so im really looking for some advice on how much should i sell my box for.. Specs: 4 15's, 15ft^3 tuned to 35hz via a 45"x4.5" port. The overall dimensions are 48" wide x 25" tall x 34" deep. The entire thing is double layered, except for the bottom..its bare mdf on the outside but the whole inside is coated in fiberglass resin.. http://i1223.photobucket.com/albums/dd509/Elrey7698/de7c216c.jpg http://i1223.photobucket.com/albums/dd509/Elrey7698/fe895540.jpg http://i1223.photobucket.com/albums/dd509/Elrey7698/abd78364.jpg
