SPL & SQ / Fabrication

im getting my system installed next week. Am i going to get bored of it after a while? Will it not seem as loud as it was when i first put it in because i got used to it? I am going to run 1500 watts rms. i have a sundown sae 1200d, 12in fi bl fully loaded, 0 gauge amp kit, and im going to do the big 3 upgrade. This is all going in a 2010 maxima

ok so the car is a 98 Dodge Stratus. I have to have access to my spare tire and would prefer a removeable enclosure but thats probably not happening. What i have now are two boxes 3/4" MDF 3.13cubes each tuned to 36hz. i want something that'll look more custom and less amateur. I've considered finishing my boxes and what not but its really not worth it to me, i'd rather just toss the boxes (not actually throw away) and start with fiberglass. I'm pretty good with fiberglass but never tried it in cars/audio, i think i can manage though. what i really need from you all is ideas on how to make this look good, i'm wanting front firing subs like they do now, and my amps a…

This is the final version of what's going into the back of my truck. (1) About 20 ft^3 box (2) ~15 ft^3 after port and displacements (3) somewhere around ~220 inches^3 port area (4) tuned to 32hz Thanks! * If you can't see the image then flickr is blocked where your using the computer.

not for sure where or when this happened, james herren sent it to my phone, hence the crappy quality. anyway, figured it would be good for some laughs. and yep, it's a 172.2db run. wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

Hey guys, I am gonna start a few projects and try and glass a few things, I want to put 2 8's on my rear deck and something upfront to put the tweets on the dash. I can't put them in the A-Pillars so I was going to put them in the corners of the dash and I want them to look clean. I was wondering what kind of resin and bonding agent? I think you mix the resin and something else before you put it on the fabric, I read about it a while ago and I will go over it again because I don't remember much. Just thought some of you guys would have some tips on how to do this... I've got some pretty good ideas to actually design it but I will touch back to see if it is plausible... …

to seal this gap inside my box....if i glass it, whats the absolute BEST way to approach this, so the glass doesnt ever pop off from the bass over time?

I was thrown into the fire so to speak at work, designing and building a box for 2 phenox gold 12" subs and i found out our company policy today is to resin the entire inner box and glass the corners. I do not believe i have enough resin to coat the entire box so my question is this: does covering the box with resin or any section of the box improve its performance? should the corners be glassed and if so what is the best way to do this? i was shown a corner piece with resin and kitty hair pressed into it, it was not smoothed. i need to finish the box tomorrow.

if your going see you there,,,cars still not ready but im taking it out anyway

What wood glue iis best to use and caulking should it be hard or more elastic like for sealing?

144.3 in the middle of hte dash on the AC and i forgot to turn my bass knob all the way up, it was set to 3/4 it was on track 19...whic his 38Hz...wow. [email protected] also, the both doors and windows where closed, which isnt MECA style. my nuts where vibrating agianst the seat and my nose tickled really bad. so windows open and mic on the floor and bass knob al lthe way...145 on the AC shoundnt be a problem. and it was a new mic, or so says the owner, so it was still a little stiff, the highest hit on it so far was 149.5 and he geussed mine to be 140dB and hte pansy guy that sat i nthe passenger seat started plugging his ears at 141dB...i tried to talk to him and a…

so im gonna go active again.. im going to use the new sundown neopro8's head unit us going to be a Pioneer FH P8800BT not the bestfor active but its what i have. amp is sundown 100.4 v1 so im open on tweeters... i used these https://www.madisound.com/store/product_info.php?cPath=45_229_324&products_id=1466 last time.. they were decent, and small... and i could mouth them with out alot of custom work or cuttin a 3 inch hole! but im open to seeing what advice is giving. i also wanted to ask a few questions. last time i went active i bought 3 sets of tweeters before i got dialed... i would LOVE not to do that this time. so would these help me stay out of rang…

Okay I'm seriously considering going active for a few reasons: I want midbass with authority, hopefully better sq since I can tune everything, and I like to fiddle and adjust shit like crazy so this will give me something to work on and "perfect" so to speak. Tweeters and or mid range can fiberglassed to a-pillars or installed in dash. I'll likely try both. Midbass 6.5s will be in kick panels. I once heard a hybrid audio demo car and it has 4" mid ranges, 6.5" midbass, and 8" subwoofers, no tweeters, and it sounded awesome. Not saying that I'll be able to get away with not using a tweeter. Let's start from the bottom. Midbass I'm looking at: peerless sls 6.5s http://www.m…

Okay, from what ive read over the past few weeks ive decided that i want to go with an active frontstage. My DEH-7800MP is capable of this from what ive read. I plan on glassing the front doors to accept a well acoustically matched woofer and tweeter combo, i was hoping someone here could give me some suggestions on what woofer and tweeter to use so that i have little flatspots in my sound. Also for reference i hate harsh pingy tweeters, i don't particularly like all my highs to sound like crashing symbols! lol.... With switching to an active front stage this also means i will be completely losing my rear audio am i correct? Thats the only thing ive been confused about! T…

it was hot & Hummid --- w/ 2 dead batterys got a 148.1db all i needed was 2 points to go to finals so i am in there

I am building my first box for my 4 aa's ported to around 25-28 hertz and about .75 cubes per chamber any tips its going in a 1994 gmc serria reg cab.

today is a little local show..nothing big, again sponsored by stereo one (yay )...so i'm going up to see what i do on a audiocontrol mic let ya know later!! wheeeeeeeeeeeeeeeeeeeeee

I want to go huge, so im goin to. I would like to get: Sub-Fi BTL 15" or 2 12" Amp-Sundown Audio SAZ1500D or Soundstream DTR1.3400 Alt-Iraggi Battery-Xs power (size unknown) or kinetic I dont know what to do about electrical, i know am going to do the big 3, i also know i need a new alt prob. Please help me out here, i want it to be cheap but i want good quality stuff to, i also want to do really well, ive been to 3 SPL comps and there sick, i loved seeing wat people did with their cars and what not. If you think there is a better sub or amp, let me know for a speakers i wont pay more than 500 for one and 750 for 2, for a amp i will not pay over 1000. If you can help it…

this is my plan. im building a box that has 4 nightshade 15s. i designed the box on a 3d program to scale. the box is 19.5 cubes. the port is 7inches wide and 38.5 inches tall. that gives me 269.5^2 inches of port area and i need 12-16^2 inches of port area for each cube of airspace. so ill make the port area requirement. the box is tuned to 30hz. i will also be having all the walls 1.5inches thick. everything will be liguid nailed and screwed together.what you guys think? i cant seem to get the pictures to upload. i dont know how to get it from google sketchup to a image hosting site. any help with this?

So I was looking at pics of banginAltima's Altima and noticed the external aero ports were facing into the car thru the folded down rear seats. I'm building a box for 2 Fully Loaded 15" BL's and was wondering if I can do something similar. However, theres a catch to my set up. I have a 88' Grand Marquis that has a solid, non-folding rear seat. So I was wondering if I could make custom external aero ports thru my rear deck between the 2 6X9's. Would that have the same effect as it did in Altima's car? He gained about 4Db when he re-designed the box and port set-up. Or am I just being unrealistic?

I am looking for some songs with very good LOW bass notes. The best I have so far are: 24 23 by Trae (and by jeezy, there are two versions), Dopeman by OJ Da Juiceman and In Tha Hood by Trae. Preferably not chopped and screwed (or slowed), as I can do that myself if needed. Thanks, --Chris

what is a good primer for mdf boxes a link would be very helpful thanks

whats a good tuning for a subwoofer box using 8" for sq purpose and would bring out the best musicality beats for new wave songs? swing out sisters, bizzare love triangle original track, gona get your love, godfinger, reasons, etc etc i was thinking of using a sealed box, but the 8" on a sealed box would just produce hard beats.. i was thinking of 38hz on a 1.0 cubic feet? any suggestion? im kind new to SQ system, and im having a hard time deciding on how should i tune the box or go with a sealed.. i would want the output to produce hard beats when needed at the same time could produce long bass when needed.. :puzzled:

I started to build a new enclosure today. Gross interior is 12.5 X 53.5 X 7.5 bottom and 3.5 top, so 2.5 cubic feet gross. I am recessing the amp and the panel is 22.5 X 13.5 X .75 sunk 1.5 into the enclosure. There are (4) 1 X 2 X 55 and (4) 1 X 2 X 12.5 to account for and the displacement of the sub (RL-P) I think is .18. I want to tune this thing as low as possible (28-32 Hz) so dual 3" ports probably. How long do I make them?

Pods are done... they didn't turn out to bad, here is the pics.... ohh yah they sound a ton better http://www.project04.net/gallery/main.php/.../pods%20001.jpg http://www.project04.net/gallery/main.php/.../pods%20002.jpg http://www.project04.net/gallery/main.php/.../pods%20003.jpg http://www.project04.net/gallery/main.php/.../pods%20004.jpg
