SPL & SQ / Fabrication

Hello, I have 3x SSA DCON's in a box that I handmade from a design from a member here. I recently bought a new SUV and the box will not fit. The box is too wide by 1 inch. The inside area of the port now is 14 3/8" X 7 1/2" ....if I cut 1 inch off of the port then the new port would be 14 3/8" X 6 1/2". Would this change the sound of the subs a lot or would it be ok to do this ? Thanks in advance for any help.

I currently have 2 SA10's in 2.5 cu ft net tuned to 32hz. They are running at 1 ohm off an SAZ-1500D. I'm pretty happy with them, but the box is the wrong shape to fit where I want it. This is going in an 03 Lincoln town car on the hump behind the seat on top of the gas tank. I have 41" of width, 18" of depth, and 10.5" of height. So I should be able to get 2.5 cu ft net, but just barely. One reason I'm considering the skar subs is that I get a free box. I can get 4-8's in a custom ported box shipped to me for $500. Or 2-10's for $380. I've been thinking about 8's since the sa8 came out. And the box would look nicer for 8's since I could do a flush mount baffle. I don't h…

hi all , just need dimenstions for a ported box, for one PIONEER sub TS-W121SPL its the same as the premier TS-2000SPL, thnx for help

Okay got 4 Old ass but brand new in box, pioneer SVC 150 RMS TW-W33C subs from the local shop, for 100 bones. I figured it'd be a good start for 4 12's to mess around with. Well i built a Box the size of the Explorer XLT's cargo area. So thats 30" Deep, 40" wide, and 16" tall. (exterior demensions). Anyways made a port thats like 3" wide (give or take), and about 5" deep. Well what did I tune this thing to?? I have no theile small parameters, for the subs so it was just a shot in the dark for this project. Its almost as good as my 2 Vipers in 47hz boxes made for DD's. Anways this setup is prolly going soon. I am trying to get jcc's 4 Vega Vega 12's to put back there next.…

Made another video showing the rest of the kerfing process!

Tought to explain, but here it goes. I plan on using an 18" sub in my car. Due to size restraints it will be firing up into the lid of the trunk. Now, has anyone tried to make a baffle to go on top of the sub? The baffle would be touching the box at the back of the trunk and be touching the very top of the trunk at the front of the trunk. The baffle would span the entire length of the trunk. The sub would then fire into the baffle and create compression loading like in a hatchback. Damn, that is tough to understand. If anyone knows what I am talking about and has a better explanation than please feel free to elaborate. I just drew it up quick. I am just wondering if the …

just need to know if anyone could tell me the port lengths inside this box http://www.ebay.com/itm/4-0-FT-3-TUNED-32Hz-SLOT-VENTED-CUSTOM-MDF-SUB-ENCLOSURE-2-10-INCH-SUBS-/400326246337 id rather make the box instead of buying it lol, but if anyone could be so kind to help out thatd be great

I have an old lanzar max12 subwoofer. My friend wants to get a system for his car but really dosnt have much money for one. If i put the max12 in a custom made t-line box that i made and gave it like 200rms would it be decently loud? Or is there something else i should do to get the most out of it? Im being paid to install everything and make his box so i do want it to turn out very nicely if possible. What does it usualy cost to wire for an amp and just put the box and sub in? (iv done all my own stereo on my own so idk how much to charge him...)

What is the best way to determine the frreq of a box? How do you calculate the Hz it will be tuned to?

hey im putting 4 l5 15's into my van but was wondering iwhich way i would be louder, if i had 2000 watts going to all 4 so it would b 500 a piece or just do 2000 and only hook up two for 1000 watts a piece , in my spl class for this year i cant exceed 2000 watts

Just like the title says, what is the best way to splice a wire? Solder? If so what kind? How about some sort of crimp thingamabob?

From what I've been reading, using a ported box will give you a 3 db gain in output, as will using a second subwoofer. Right now I'm running a ported Dcon. So, if I were to buy another one, it would pretty much be a waste of money to run them sealed? I should be getting the same amount of output from one ported as I would from two sealed? (Someone should really change the title under my name from "Member" to "Forum idiot". )

Hi everyone I am about to try my hand at making a box of a different type for the first time. Mainly I'm doing this because it is very interesting to me and also because I can stick this speaker in my girl's car and if it sounds awesome I;m hoping she allows it to take up that valuable "grocery getting" real estate in her trunk. So I'll start here. Vehicle : 2002 Lexus GS300 Location in the vehicle: Trunk Space available (Length x Width x Height): 36" x 24" x 22" Subwoofer make and model: Ampere Audio 2.0 8" (spec's below) Subwoofer Size: 8" 300 Watts RMS Number of Subwoofers: 1 Type of Port (Kerfed, Slot, Aero, etc.): slot (T-L…

For those with hatchbacks and/or hatchback experience. Folding rear seats, so large enclosures will work. What enclosure has worked best for you? CRX style? Sub up, back, forward, or angled towards glass? Port up, back, forwatd, or angled towards glass? Daily driver. I'm tempted to try something in the Mazda for the uberwoofer. Can be pretty large, so uncommon enclosures can work as well. It'll boil down to having the sub and port firing forward between the seats or any of the above ways.

I recently purchased an A.P. Axis 15 and was suggested to make this box. Box is to be 3.0 cu. ft. net and to use 4 - 4" pvc ports. Because of box dimensions I'm not able to use flare ports so this is gonna be straight 4" pvc. I'm told the beauty of this type of box it the ability to change tuning and also seal up the box using plumbing inside pipe plugs. A ported and sealed box combination. My concerns is port noise. When I brought this up I was told that I would not have that much and that I would certianly not hear it while playing normal music, just on bass tracks. Is this accurate information? I think this box concept is great but if it's so great why isn't …

1st run 150.7db 2nd run 150.1db charge batterys a few min. 3rd rub 151db got 1st place

Im tryin to see if anyone can custom fiberglass me some door panels, entire door panels for both of my doors of my car. I know some companies locally that do it but they charge extremely, i mean EXTREMELY large amounts of money for it. To give you an example, they charge $1,500 to do a 14cuft wall in my car.... i dont know why they told me that a while back but that's not what i wanted from them anyway because i know how expensive they are. I'm lookin to spend no more than $300 per door. Is that too low? I can't find anything for a Scion tC.

i got a kicker l7 15 dual 4 wired to 2ohms into a hifonics brutus 1200. i just got my box built by one of my buddies who owns a shop. the box is roughly 5 cubes tuned to about 35hz pretty sure. i got everything together last night and spent all day today playing around and trying to tune it and it just does not want to put out those real lows in some songs. sounds like its just blowing air. None the less it tears apart the mid to high bass. i dont know what i could do to change it up maybe rebuild the port or something. not to good with this stuff thats why im asking you guys. inside of box dimensions: width 39 height 13.5 depth 18.5 its got 3 in wide slot port its just…

Well I was bored so I made a couple vidz. Hope you enjoy :bigclap: Up first is a vid showing air movement from drivers window Breaking the lil guys in. Strange noise is not the subs. The closer the mic gets to the port the worse it gets. Lastly my no flex flex vid LMAO!! Will post more if ya want!

Alright, I'm going full blow post with this. I'm tired of wasting paint. I've been painting this damn thing with color now for around two weeks. Giving plenty of time to dry between coats, wet sand, etc. and it still looks like shit. There's 6 coats of automotive primer on it before I started painting as well yet it still continues to soak in, like so. This is after around 3 coats of paint. BTW the color is deep jewel green with the metal flake in it. Same color that's on my '70 chevy. And this is after around 8 coats of paint. The picture was taken this morning moments before coat #9. So what can I do with this? I was wondering if a coat of clear over the pain…
