SPL & SQ / Fabrication

hey whats up guys i have seen on the internet and on a few forums people using bedliner as a sound deadener does it work and has anyone had any good or bad experiences from it

is there any discernible difference between a square port and a circular port. I'm thinking about using a circular port tube from somewhere like Elemental designs. Mainly due in part to my lack of knowledge and how to build a ported enclosure.

Most of you know that there was another vehicle added to the fleet. 1999 GMC burban. Now the old 97 DUBurban had a massive 8ft^3 enclosure in it and housed 2 Brahma 15's. 4000W amp running them. Well this time its all about saving space and keeping everything stealth. My plan is to flip the spare tire around and glass the inside of the rim. Then i'll glass a mdf enclosure onto that so i can get my needed air space. Right now ive got only 4" of cargo area taken up by the enclosure because its to tall and wide. Sub will be my 12.o.44 sealed running off of my autotek 5600X. Bro will be doing the glassing work since he has the experience. No idea when this will all take place…

I've got one of the few remaining 18" Inhumans that I desperately want to hook up and listen too before I get rid of it. I designed up a quick box in WinISD and came up with these numbers. How do they look to everyone? 8ft^3 tuned to 34Hz 98" of port, 20.31" in length Nothin special, just a good daily driver box.

I want my subs to face up with the port up like one of my previous boxes. I cant seem to get a lot of input and like Ive said previously the pro designers dotn wanna mess with a camaro enclosure. Assuming ive done my math correctly does this look like a suitable enclosure? I just started using sketchup so I have figured everything out so nothings 45'ed or anything.

considering doing a box with aero's wanna tune it lower also around 30 hz right now its in 3.4-3.5 cube at 34 hz on 3k rms to get the tune i want and my depth issues guided me here, i hear you need to have roughly the diameter of the pipe distance from flare to back of box for it to be right? so final figure would be 4.25 cubes at 30 hz with 1 6" Aero at 16.5" for that tuning and thats from flare to flare. Should i just go to 2 3" aero's or what do i do hear, because i will be going 16.5"+6"+1.5" for the MDF im too close to the rear hatch, it would be like 3-5" from it

I been going back and fourth for the past few weeks about doing a enclosure to go under the rear seat in my truck. I entered my measurements in the enclosure calculator on the12volt. and i came up with 4.7 cubic ft but it have the transmission hump thats right in the center of the floor and i dont know how to subtract that from the total that i got from the enclosure calculator....do you guys think and enclosure like this would work with a external port? Im still looking around for some good 10's that would work with 1 cubic ft or less

POLYURETHANE FOAM the reason im writeing about foam when im talking about fiberglass, is that you can make mold's out of thing's. just fiberglass over it then get some acetone and it will eat the foam and keep your fiberglass mold. they have 2pt. polyurethane foam that is equal mixing self-rising foam. most 2pt. will start foaming around 45 second's after you mix the two, and will go for a few minute's after. now it will expand around 25-30 time's it's liquid form. unlike polyester foam, polyurethane foam it's compatible wth both polyester resin and epoxy resin. (which mean's you can paint the resin on and it wont evaparate) now they have polyurethane foam sheet's allread…

I need a sheet of hard plastic like ABS to use in a bunch of places in my car. Does anybody know where to get anything close to that? I haven't really done any research so if anybody could point me in the right direction I would really appreciate it.

i am doing a 4th order in my grand cherokee and was wondering what would be a good sealed chamber and ported chamber. Equipment i have right now: 2 18" DC lvl5's 2 Sundown 4500d's 1 300 amp powermasters alt 8 3100's

Come summer/next fall id like to hit a few competitions and then head to daytona even next spring break. Because ill be finished with online classes and im officially done with soccer. the onlything preoccupieing my time will be work and cross country. As for ocmpeating, im doing competition on a budget. Id like to run my BX1205D it even less for power and run maybe a pair of 12's. Im thinking a pair of 187 12's in a 4th order bandpass. Ive always wanted to build "The Wicked One" to see how it performed. The 187's seem like a good canidate. Reletively high efficency, good Xmax, and reletively low inductance. For Competition i would build one with a wider throat for high…

Finally picked up a few sheets of MDF to play with to make my explorer box, what should the minimum port area be for 2 15inch RE SX's? So far i have messed around with the RE box tool and came up with a 6.1 Cube box tuned to 34.7hz with a port area of 74square inches. My available measurements seem to be 41 inches wide(before wheel well bumps), 18 inches deep, and i don't want to reach over 20 inches high on the height. If anyone can throw some suggestions at me for the area of port needed or maybe a box design they have used in their explorer it would be much appreciated. Thanks!

ok guys, its time to get some plans going for this box. im using 2 12" ssa zcons and pushing them with a audiopipe 3k (ONLY UNTIL I CAN AFFORD A BIGGER 4K+ AMP) so its not my perminant amp here fellas. i took my max dimensions tonight and used a box calculator and i have 6.81 cubes to work with. as for tuning, im not really sure. i like my lowwss (30hz or so) but i want to be able to throw up decent numbers. i was thinking 34-35hz maybe?? not really sure. thats why im here asking you guys for help on this so i dont waist my money.

It's about 7.4 ft^3 with a 13x6.5" port. Two 12" type r's are going in and will be running at 1000wrms. EDIT: What would be best to tune this box at? I'm doing daily and want it to sound good, not just loud. EDIT 2: Listen to mainly rap.

hey im workin on my new box and im puttin mirrors in side and i need to know how to get them securely attatched where they wont fall off later does anybody have any suggestions ?

When doing a blowthrough setup in a pickup, will it really make a difference as to whether the truck is extended cab or standard?

I know the pic is small and I'm not saying I will do this(but hopefull) Should I be concerned about cancellation problems or is this design ok

hey guys i got a question for ya. im building a box for 4 15 fi ssd's and i was wondering if a box built at 15.5 cu ft. net and tuned to 32 hz with 200 sq in. of port. its going into a blazer. think this box will work? any info would help thanks.

my box is going to be 7 cubes after displacemets. box is 20 inces deep (so one port side can be 18.5") 112 inches of port area, 33hz my question is, can i do two ports, each 18.5"x3" at 12" long for ~33hz would that yield a net port area of 112 and keep the 33 hz tuning? if not, how do i go about calculating this? im going to try to do a drawing real quick to help you see what im doing

I have a Soundstream Reference 500sx rated at 500 watts in 1ohm & 2ohm, is there a difference in sound quality in the different load and what about subs, does it make a difference in sound quality if you have a dual 1ohm or a dual 4ohm sub wired at 2ohm load are there any differences in sound quality.

just starting to figure these enclosures out a little. any one got any info.

I need Help for my 10 Xcon I would like A Ported Box, would like to have my tuning around 32 If opti.

Hi guys, I 'm always trying to improve my system. I have a 15" xcon and a 1500 watts Sundown saz amp. The car is a hatchback toyota Auris, with a little trunk. I had a slot ported box with sub up and port up, at 3.5 ft3 at 32 Hz. This box was too big for the trunk, but I thought it was not the right one for my car. I've heared this same box in a smaller car, with the same setup, and it was ...insane. In my car, it was not really loud. I have, now, a 3ft3 sealed box, with the sub firing back ; I found it was better than firing up. So, here is my question : if I want to do another ported box, what would be the best choice ? Sub and port firing back, or sub up and port back …

I remember playing around with making boxes and stuff and had some different software. I had somebody guide me through it before, I had a box deign for my other truck. But with it, I have to make some decent modifications to it to put a box in it. With my Jeep I can just design a box, go pick up the stuff, make it and drop it in. I think now that I can do that, I will actually pay more attention to how to do a box, have more interest in it. I was recommended subs up port up on the drivers side, not sure if it will fit or not. The max exterior size the box can be is 41.5"w, 16.5"d,21"t... I'd like to design a box myself but obliviously get some help with it. I think if I …
