SPL & SQ / Fabrication

I was wondering how I can properly set and adjustable a LOC with a stock radio and aftermarket amps. Equipment: Stock H/U SVEN LOC Zed Minilith Sundown 100.4 The RCA's after the H/U are going into the Mini and split (y adaptors) to the sundown. The LOC has four individual knobs for setting the input signal. Sorry if this is not enough.

What would be considered too small for a round port (in terms of diameter)? I'm trying to design a ported box (0.7 ft^3 ~ 24hz) w/ round ports for an RL-I 8" and the only diameter port I can use w/ a reasonable length is less than 1.5"...won't this create noise? I just can't imagine using a 1" port for that monster... What's the rule of thumb y'all?

Hi guys, A good friend of mine want to use his Fi btl n2 15" in a new ported box. He was using mine until I sold the box. This will be a temporary setup, as he is in the process of ordering a second btl, and the box for the 2 is ready (he had 2 Xcons 15" in, before). So, the box he wants to use has those dimensions: 83 cm x 37 cm x 50 cm 32.7" x 14.6" x 19.7" Those are internal dimensions. He has 2 4" flared ports that he wants to use. What length should he make them to achieve a 32 Hz tuning ? Thanks very much for your help. I use to "work" with RAM Design for L port boxes, but I want to try the forum members for these round ports.

Planing on tuning it to almost 42 hz. This will be a competition box for my 04 jeep liberty. Subs up port back left. My question is what type of sq foot should i use for this box. Alpine's site says use around 2.5^2 per sub in a ported enclosure. Also if it matters im planning on running these off of a Sundown SAZ 2500d

Just made my first go at this google sketch up and was wanting some feed back to see if i need to make any corrections i'm building for either 3 fi bl 12's or 3 psi platform 2 12's heres a pic of what i have came up with so far

I only get static when both sets of rca's are plugged into my 4 channel avionix amp. When i have ony 1 set of rca in the amp it is clear (Static-free). I tested this on both sides of the amp and the same thing happens regardless if i have the rear rca installed or front rca installed or vice versa. ANy ideas?

i have 3 300amp breakers now... im popin one of them somtimes.. the onw between my amp and my rear cells,.. i know that once thay pop thay pop easyer... i bought a new one on ebay... i was stoned and bought another 300 amp!..... so now im looking for a 350 amp or a 400 amp CIRCUIT BREAKER... any ideas?

i am trying to build a box for 4 of my kicker cvx 15's. i called kicker and they recommending using separate 3.5 cub. ft chambers tuned to 38 hz. since this is gonna be my first box build is there an easier less way to build the box without having 4 separate chambers? maybe 2 subs per port or all 4 with one port. it is going inside the car. maybe even a wall design. my available space is 32x56x36.

Ok so I am going to be going to sevierville tomorrow and stopping by the place my brother in law works. He said I was more than welcome to use the equipment they have. --read cabinet shop-- Sooo I figure why not go ahead and make a better box for the one avalanche. I'm looking for 3.5-4 cubes, tuned to 21hz. I would like it to be 30"W X 16-18" H X whatever deep. 16" high is better than 18 cause it'd be easier to fit, but i could do 18 if it really helps that much. I guess i will do slot ports so i can actually get a working box quickly. I will probably be using 3/4" MDF. I'm thinking a port on each side with the woofer in the middle. BTW its a 15" sub and the …

Pic of specs (or really close to, but hows the design, first ever, opinons, ideas, positive feeback.... will it work?? lol thanks guys!!

I'm trying to figure out an enclosure configuration for 3 SA-10s, just not sure which way to go. Was looking at doing a downfire enclosure with an aeroport(s) firing to the side,. Just curious if there is any drawbacks to something like this. I like the idea of it being less visible, as well being a little more protected from the elements if the top is down. If it's a terrible idea, I'm all ears for better options. Thanks

hey all been looking to make a t-line for a large scale project but wanted to start off with something small in case it doesn't turn out so well. now i no the port area has to be the same as the subs cone area, and the length is the speed of sound divided by the fs of the sub then divided again by four. but ive been told some have a common chamber and some don't and also im trying to figure out how to tune it or can you only tune it to the fs of the sub? any help would be greatly appreciated and ill let you guys know how it turns out once im done thanks mike E

hello all i have a system installed thanks to the great guys at phoenix gold and its really fricking loud which attracts the hoodrats and hence, i have no window now. So i went to go get a new window and the thing is almost 700.00. so i looked at lexan and that is way frigging cheaper. so heres the deal. How in the hell do you install this crap. i know i am supposed to be able to cut it with a jigsaw and like sand it or something but i dont really know how or what techniques to use or anything else. i need to know how to put this in or someone that does it needs to do it for me but either way i need the big fatty lexan in there. Since there is literally nothing on this su…

first off here is my box: here are the plans i used to build it: 2.26cuft@34hz i have a 12" fi Q BP power off 1200 clean watts and it sounds great in the car but when i pop the trunk while the sub is playing there is this whistling and its really annoying... seems to happen worse on low notes... what is the cause, not enough port area? cuz i am pretty sure there is plenty of port for this sub ive already decided i'm building a new box eventually but this is an annoyance that i would like to avoid with my next build tia!!

Just brought home my second first place trophy in as many competitions. Little higher this time. 150.1 In modified 901-1600.

Hi all, I'm designing a custom boot for my car, what is the best way to place 2 x 12" phase aliante subs in a boot? I was told the best place would be one on each side (one on left side and the other one on the other side). and I would love to do a fibreglass job something like this: but on my car would be 2 of them..so one on the left and the other on the the other side. what do you think? or is it better to do something like this (which one is better, sub firing the front of the car or the rear)?:

Where is a cheap place to get some 3" Aeroports ? I saw them for $13.88 on this site, just wondering if there are any places that are cheaper. Its gonna be about $35 shipped for 2, which isnt the most appealing thing ever

jsut curious who all is excited that both will be offered in the ame even? I know me and my team are. Who else?

Can anyone help me design a ported box for 2 RE 8's? Needs to be 1 cube, around 32 hertz... I just don't know how to figure out the Port Lenth (want a slot port), the external demensions (with port displacement), and so on... Any help would be great... Oh, it's not vehicele specific, just your basic retangular box... -BW

Anyone have the meca world finals results? Just curious on how our shop vehicles would compare..

So I don't have a lot of tools and I don't feel like ordering flush mdf rings so is there something else that I can glue to the base of my ring cut out to give it that same look when I fiberglass them...I do not have a router and I'm not going to buy one just to make 4 flush mdf rings...so Im just wondering is there anything esle out there.

Hey everyone. I am not sure what the policies are with box designs are here so i thought i would ask. If I asked for a design on the forum and someone does give me one do i pay them or what?? this is just a picture of the box. Like the dimensions of the pieces of wood. I could make the box but i have no clue on how to design a port or tune a box. If this was not clear or difficult to understand than let me know or just delete it , hha Thanks, Matt Cusack

Okay so, I got my designs, and lowes completly messed up all the cuts, so I have to take it back and complain and hope that they give me new wood or something..... So in the meantime, I just "sketched" up this box. Here is a pic here is the google sketchup file http://files.filefront.com/fibtl18skp/;13080625;/fileinfo.html for anyone who wants it Let me know what you all think! (I didn't make up the specs for this, a help from another member on this site did, I just drew it)

Friends Does anybody know any alternative methods in contacting Custom Car Audio Home I am trying to order a box but can't seem to get a reply either by phone or E-mail. I also tried contacting fisher customs and have not gotten a reply from them either. R, Julius
