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... …

I am currently taking advantage of the Audibel Customs free enclosure special and getting myself an SSA Icon 12". I am going to be going with a ported enclosure, and Quentin is currently working on my design. the first design he had was with the sub on an angle, firing towards the hatch, and port firing out the top. I had envisioned a upward firing sub and port, and a raised sub floor in the back to make it all flush. Now I realize that the box is just going to be so big regardless that the sub floor idea went out the window. I am only concerned with it hitting hard, going deep, and being able to keep up with my tastes in music. I drive a '05 Scion Xa, 160 amp alt, 0g …

snoopdan uses pink panther insulation to seal around his box so it acts like a wall in his cherokee. I just got done building my box in my scion tc with 4 15s and i need to seal around it so it can act like a wall. I was gonna use pink panther but have 2nd thoughts because it states that it's purely a thermal barrier, not acoustic barrier. Is there any methods u guys use or can persuade me with facts as to continue to go with pink panther insulation or is there a better method?

Ok so speaking purely visually, i understand a basic motor and the LMT but XBL^2 i've never seen a good pic of, what exactly is it and how does it differ? what pics i have seen, i can't tell the difference from a normal motor. Now, someone explain in some more depth for me, or point me to a good link, the way the magnetic force helps hurts the voice coil movement. I'm not understanding why a lateral force is necessarily a good thing. Next, why is the cone concave instead of convex? Has anyone ever experimented with flipping the cone over? What affects would this have on the frequency? Obviously i'm procrastinating studying and my mind needs anything else to think abou…

Finally designed my first enclosure. It is for a 12" GCON. ~2.5 ft^3 tuned to ~33hz. Does my math/design look correct? Does this look like a design that will translate into the real world effectively? It will be going in the trunk of a 1996 Honda Accord sedan powered by an AQ1200. This is what I came up with to fit my trunk space needs. Any critiques and opinions are welcome and greatly appreciated.

i talked to my cousin earlier and he was explaining different box designs to me, he said that he had a box that was a cross between a t-line and a horn design box, he sent me an attatchment w/ pictures of the different types but i cant find formulas anywhere, i used the search but none of the links for formulas worked so i was hopign someone could help me out... thanks

The box is for a pair of DC Level 4 18's in the back of a 2007 Suburban with all seats in, including the third row.I have the following for outer dimensions to work with: 27 x 49 x27 Now my drawing shows a height of 26 1/2, but I'm only counting the height at 25 3/4 in the Box Calc program because the top board was double baffled. I'm seeing a box tuning at 33hz. Here is my other design, this one is pretty much the same as the first except for both subs and port firing up. What do you guys think? Box Design: I think I still like the whole port and subs up design better. My current box is a dual chambered double slot ported box. Each chambered tunned to 32hz. Has anyone…

hi every have another question my step dad bought me another sa-12 as a late xmas gift and he gonna help me build a new box for my 2nd 12 gets here but the space i have is 39x16x22 1/2 which is w x d x h. now my question is is it possible to build a box for these two subs with this much space ? and how high do you think i could tune the sub's at as well if it's not i can add more height to the box.

ive been hearing that the tantrum amp can actually get u put in higher power classes in some organizations because of the output at 4ohm..anybody know if this is true or not? and if so what organization does this.

I am trying to find out how many cubic feet i would need for 6 SA-15s in a ported wall It will be ran by 2 2600w soundstream amps and I willl be playing rap and bass tracks.

Its been a while since ive been on here... but i need some help... I'm building an enclosure for my new car (02' focus ZTS) which will house 4 10" woofers firing towards the rear of the car at a slight angle with the deck lid.. (ie 35-45*) question one... is this going to cause a lot of cancelation? question two... i want to build a seperate air chamber to fit the spare tire well... and connect the two chambers to increase my overall air space... will doing that actually do anything for my airspace considering for now... the box is sealed? thanks for any help -AcId-

i have a 1997 mercury mountaineer with 2 fi q18's DRUMMING~! they are powered by a t20001bd rockford. i am losing so much pressure out of the back glass do to flexing. do they make clamps for the back hatch to hold it down? its a daily box in now and will future be a crx style spl box. i currently have a 12 cube crx style box with 120 sq. inch of port. thanks for any and all help!

There are 2 drivers in each side wall that would acoustically, i assume, act as port length. So, if that's true, does leaving just the opening in the back act as length of the side walls which is ~25" long? also, i've never had the time to question these types of designs but does anyone have anything negative to say about drivers in the side wall like that? I've seen pretty much all different kinds of setups throughout the years and this particular one is not new either. I just don't understand what actually is going on when the front wave of these side wall drivers interacts with the port(2nd question).

i got bored and decided to draw this up, its right around 2.5 cubes @ 35 hz. gonna be for two 10's ( AQ SDC2.5's) Its gonna go in my chevy std. cab. Any comments or suggestions?

I have a friend that wants a box built for a 8" sub. I have some 1/2" MDF that I could make it out of. The box will be sealed and not have a lot of flat surface (maybe even some glassing involved to make it fit). Would this be a good idea? I'm not sure about the thickness of the MDF. The sub will only be seeing about 200rms or so.

hey, im thinking about building a pretty loud setup with just 1 bl 10. its gonna be for competition use only, just for the hell of it lol. its already in a good daily box...but i kinda want to build a burp box since i have 3/4 of a sheet of mdf laying around...im just kinda lost at what to tune it to. ik im supposed to tune high, but how high? i have no idea of what my car peaks at tho, since i dont have anybody around here that uses a termlab. i am using a hifonics 1610d and will b running at 2 ohms on it so about 1200 watts is what the amp puts out. it will be a box for competitions only, so if anybody has any ideaso of what to tune it to that would be great. also, its …

I know I've seen plenty of people use spray/roll on bed linings for the outside of their enclosures and such. I am wondering two things though, was it applied to the bare MDF or with a primer on the MDF first and how well is it holding up after "x" amount of time? I'm about to start on the enclosure and amp rack for my Jimmy. I had planned to paint the port to match the truck and use standard charcoal colored cabinet carpet to cover the box and amp rack with. Though upon thinking about possible liquid damage to the MDF on the floor/amp rack I'll be building I thought perhaps the liquid bed liner may be the better route. I have no experience with it though so I was ho…

I'm going to build a truck-style enclosure for a Fi Bl10 with a 3'' aero. Dimensions are w: 38 h: 12 d1: 6 d2:8 This is 1.217ft^3 internally. After the bl10 displacement it comes out to roughly 1.1ft^3. When determining the port length, online calculators asks for: Volume of Box in Cubic Feet Tuning frequency Port diameter Number of Ports I want to end up with a tuning of somewhere around 33-35hz, depending on how long of a port will fit in my box. So...... Do I put …

Does port/woofer aiming really matter that much in an SUV? I'm looking at placing the box in the passenger rear corner with the woofer firing cross cabin and port forward.

ok, i'm gonna risk one hell of a flamming here and ask you guys. i was nomeened R-tard of the month on CA.com for saying this so chances are it's gonna happen here too, but what the hell K my question is can you guys hear the difference between a 4 ohm and 1 ohm load? now im not talking about sitting in someone else's car and knowing it, but if you have a 2x2 sub and wiring it to 1 and 4 ohm load. i have tried it with a two different amps(a 2 channel in 2 ohm bridge) and my current RF bd 1000.1. although on a 1 ohm load and lower it ponds like a bastard it just sounds too off, sort of muddy... this all applies if the amp is stable on those loads of course just curious...

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