SPL & SQ / Fabrication

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.

can I make a port in a shape of a L and still tune the box too 35 hz. your advise is need badly

This is going to sound awfully newbish, because...well it is. I see all over this forum and various others about what to tune a ported box to. Well it dawned on me a while back, what does it mean if you tune a box to, ah lets say 32 hz? Does that mean that the subwoofer can only play notes above this frequency, or what? Also what particular specification(s) point you in the right direction on what to tune the enclosure to (besides the obvious manufacturer's recommended boxes, as I see a lot of people that don't necessarily stick to what the company provides.) Please go easy on me, as I am really clueless when it comes to ported enclosures (as I personally like sealed …

I sm trying to get my trunk ready for everything but before I start deadening I need to decide what to do with my spare tire well. I know I cant leave everything in there cuz it will vibrate like a mother. But if I take everything out there is just a big hole so what can I do to cover this that won't cause any noise?

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…

Memphis doesn't carry them in their site. Did some searching but only came up with the subs or some other t/s parameters . I doubt the place that sells them here will give them up cause they make boxes. They are kinda like that. They gave me recommended optimal. The port however doesn't make sense. I used Torres calc. To do their recommended port size. It's way too small IMO. 4ft^3 for two 12's with a port of 12x2.5x19long which tunes it to 28hz. I wanted to get what the actual T/S parameters are so I can get an accurate idea of how to build it.

I was wondering if anyone has ever seen a port like this? Is it even possible for this thing to opperate properly, it still sounds great, but I'm starting to think that its just the DCON making it sound good.

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

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

i can't find it anywhere, where do you all buy your polyfill?

I have yet to personally use an RTA for my own personal use so let's see if I get this right- I want to use Pink noise because that is generated to play how our ears perceive sound. When analyzing what pink noise looks like on a computer, it appears from 20hz-20khz, for every octave from 20hz, the amplitude drops 3db. So, at 20khz, it's very low compared to 20hz but our ears must be very sensitive there(if you can hear it) to perceive a flat response. So, when i go to RTA my front stage, is my goal to also (if it were perfectly possible) to achieve a full range reading exactly how pink noise is generated? 3db drop for every octave up? In the end, I would assu…

I was told by a former "audio guy" that althought 3/4 MDF is used in car audio enclousers, 3/4 partical board could be used to reduce the weight of the encloser. How tru is this?

Unfortunately due to some extenuating circumstances this year's event has been POSTPONED!!!!!! The Clayton Chamber of Commerce has postponed this year's Clayton Classic Car Show. Since the show is put on in conjunction with the Classic Car Show, we have to postpone the Clayton Car Stereo Show. We will be in close talks with the Clayton Chamber of Commerce and see when they will decide on a new date for the Classic Car Show, when we get a new date for the show I let everyone know and we will try to have it then.

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.

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.

hi, i am thinking about having woodlawn Cabinetry build my box for the 2 12" Icons and i am wondering if anyone has had any experice with them. i would build it my self my i have no tools and he only wants 205 dollers for it and thats with it carpeted and i wanted the baffle to be laminated black.

Can anyone give me a fairly straight forward design for a bandpass box for two 5 1/4" woofers? I like the one i have, but it is uber ghetto (Current Box) I would like to have it peak around 28-30hz for chopped and screwed music, but maintain some punchiness on higher notes. Box size isnt really an issue, the one i have currently is around 9in tall, 4ft long, and 3ft wide. I like the style of mine, the way it is laid out, chamber, port etc so anything similar would be perfect (i might use a plexi top; If i do go with the plexi, i'm spraying the insides flat black). I will build it myself, out of 3/4" mdf and some bracing. Only requirements are is that it must be at most 12…

I found a formula that seems to work at http://www.caraudio911.com/ under designing a ported box. But I was wondering why on step four they say to subtract half the port width from the port lenght to get your physical port lenght? When I made my box I dont think that I did this so I may be building a new one if this is important. I was also wondering if this formula works or has been used by anyone here?

I recently changed the enclosure of my sub. Nothing else has changed : same electrical, same amp,... The old one was too small, and badly tuned (too high). The new one is really a good one. When I made the change, I was not so happy with it. And after a few days I start to like it more and more! Could it be that the sub need to adapt to its enclosure for some time before playing as it should ? Maybe I am just getting used to it! What do you think about that?

Hi I need help making a spl/daily box for 4 15s, I'm going with subs ip port back and want it to be crazy loud, I have 3500 rms going to all of them how should I make the port and what to tune it to?

had today off, ran up to the shop... and did a 147.2. voltage drop was to about 11.5 or so, with just the optima of front, popped the 300A breaker. Kinetik 2400 came in yesterday, I really need to find somewhere to fit the damn thing in...

Im looking for a nice 1.7-1.5 cu ft sealed box for my 12" Xcon. It willl be powered by my SAZ-1500d. Any ideas for some nice sealed boxes on the internet?

could someone please double check these numbers. I know this box is small but that is all i have to work with and its still at the minimum.
