SPL & SQ / Fabrication

Well, that meter is comin in handy... I've got spreadsheets on my computer right now of multiple setups of what they do from 30hz-52hz in 1hz increments off of a 100w amp. I chose low power so when i make a change i can see it's difference better with low power. So far i've tested 8 different positions(i don't list all of them due to bad output and tested others with failure as well in output potential) using 1 10" sub ported at 42hz(just because it's only box i have at the moment before it gets warmer) (This is daily driver only) I've tested all positions AT THE HEADREST ONLY. So, all the Db ratings below are noticeably low. I've been to comp before in the past but m…

I was messin around and just seein where the power wire would go through, and i realized that the firewall already in use for the factory wires was pretty much full, and i don't see how 1/0 is going to squeeze in there. But a couple inches to the right and one or two inches above it, theres what i'm guessing is an unused firewall hole. Its a rubber surround with a rubber filling. I tried to see where it came out on the engine side, and i couldn't find it. Does anyone know if i could (once i find the hole, as it was a little dark when i did this) puncture the rubber filling and take it through there? If not, what should i do?

Went out to a Texas Bass Productions event today with the Sebring wit 1 12" Soundstream SPLX Quad 1 ohm.. All 3 runs it did a 151.3 Got 1st place in my class(no one was close to me). Brian(Lord Baccus) did a 151.2 with a set of bad RCA's with a Pierce Audio Products 1 off(specially made for him) 15" MOAB subwoofer, ...sorry bout that Brian..we'll et em' next time! Every ones asking about the Sundown Audio amps that me and Brian are kicking butt with....most people haven't heard of them...they are getting a ton of attention... Hoping to get higher on this single 12"...

had today off, ran up to the shop... and did a 147.2. voltage drop was to about 11.5 or so, with just the optima of front, popped the 300A breaker. Kinetik 2400 came in yesterday, I really need to find somewhere to fit the damn thing in...

I have a 97' Thunderbird that Im doing now. I wanted either a pair of Fi BTL12s or Fi BL15s. I want the BL15s because I would save a lil money on power and can be used in other areas such as the build, elec system, etc..... But the enclosure size needed is kinda on the large size for my trunk. But I can fit them in there if I angle the baffle and use 2-6" aero ports. My real question is I was reading on another forum that a guy with a mustang (which is basically the same trunk as mine) had success with his subs facing forward and his aeros on the side. He said that subs back/port side was the loudest on the meter but subs forward/port side was the loudest to ear. Has anyb…

going in my 86 towncar. trying to use only the lower part of the trunk for box which measures 44"L 28"W........... as for depth i can go w/ 17" (would be flush w/ upper back part of my trunk, where the spare would go), or i can go up to 20"D. subs up and vent/port up. can be either single chamber 1 port (whatever side) or seperate chambered t ported. give me some ideas w/ design and tuning. thank you.

The Car:2000 Maxima The build i talk to some guys from americanbass usa they sending me 4 12's sq 600 rms subs im gonna need a amp to push them they have a 1000.1 they wana send me but i need to worry about the box build 1st thats where you guys come in..lol i need to build a box for 4 12;s ported threw my rear deck now on a ported enclosure these speaker need a box volume of 1.5 Cu Ft Now i Need to figure out how would i tuned this box out to 40hz thats the max the speakers can hold so i wana give it alls its got..BUT i have no clue on tuneing a box to 40 hz i can build a reg box to 12 ported slot in the middle but on the whole 4 12's i have no clue i hopeing one of ya c…

My question is, is it worth it to double up on 3/4" mdf on all sides, or should i just strengthen the side holding the sub? 18" Fi Bl--- p chamfer and flatwind 39"x18"x22" (sub is on 39x22 side) tuned to 34.4xxx hz any suggestions? thanks. also, this is a daily driver, not going to a termlab anytime soon, just want it to be a good, solid setup for daily driving.

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!

Gains will be set low (to start off, i realize hifonics isn't top of the line, but it'll do the job well even if it is overrated).. so any suggestions on a good wiring kit to buy?

Sorry for all the questions lately, but i'm getting very close to having my box complete, and want everything to be right. So, has anyone used bed liner for their boxes? I really like the look of it, and i really dont like the look of carpet (it's allright i guess, it just seems like everyone has it). Does anyone have suggestions on what kind i should buy and maybe a lil info on how to apply it and make it look good? Thanks to everyone thats replied to my questions.

I started the cuts today, and want to put it together soon, but theres a few things i'm missing. I know i need to pilot the holes, but what size screws? I was thinking 1 5/8" Drywall screws. And for the glue.. should i just use regular carpenter glue/weldbond or something special? Also i read that MDF is porous, so should i seal it? and with what? And someone on a different forum mentioned to do seomthing different for the edges/corners.. .any idea what he meant? 1. 1 5/8" drywall screws? 2. Weldbond/carpenter glue or something else? 3. What kind of sealant if any? (recommendations?) 4. What should i seal edges with? I know its long but thanks for readin.

i have noticed a desterbing trend on every forum... when someone post about : Loud SPL or anything bigger than a 10" sub the SQ sharks come out in force and rain on our good time. but GOD forbidd i rant on one of there rich boy toys *cough JL audio cough* can we have a lil less nagging from the SQ bunch PLEASE??? how would they like it if i/we go into there threads and NON STOP SLAMM them for having over priced underpowered subs & whatever ??? cant we all just accept that everyone has a different point of view as to what sounds good

My db drag partners ride this season 4- AUDIOPULSE 15'S, WALL 8- AMPS STRAPPED, 20,800 WATTS RMS 8- BATTERIES 2- ALTERNATORS= 510 AMPERS AND 300 INCHES OF PORT -Each amp at .5 ohms just like my sundowns (same wiring on the dual amp single woofer strap) -156 legal (156.4 later that night) with three out of 4 of the 15's on -amps have not been matched perfectly yet -woofers have not all broken in -wall still has not been sealed off -no deadening yet -batteries were uncharged

What are the advantages and downfalls of fabricating the vehicle below for a SPL vehicle. http://www.we-todd-did-racing.com/browse/g...oud/51586_mp6d9 Playing with the idea and would like some feedback. Much appreciated.

When building a common chamber ported box for four subs do I take the suggested enclosure volume for the sub and multiply it by the number of subs. ex. A sub requires 1.25 cub. feet minimum. The enclosure is going to have 4 of these subs does that mean that the box should be 5 cubes since 1.25 x 4 = 5

subs: 3 12" hx2 do i need 4" or 6" ports? tuning suggestions also welcome...i was thinking 6 ft^3 @ 34 hz

Yes... I have moved from Corpus Christi and have brought back USACI to the DFW area. I look foward to getting back in the groove with everyone here. You can check out www.myspace.com/usaciofnorthtexas If you need to know who I am and what I have done, go to www.myspace.com/bigmel22 Thats my life story and I hope to lower the boom in the DFW area.

how is it done ? what am i suppose to do with the crossovers for ea. set of mids ? tweeters ? is there a diagram?

not sure if this is the right spot but anyways any of you guys try to fit 1 or 2 of these under the seat of a pick up before? the truck actually is a 2006 F 150 super cab.....dont get it confused with a super crew. Im gonna try and figure out the box today and i just thought of using these i was going to run two 8's ported off 1 SAZ 1500D. im also considering two RE 8's too but i figured the AA would handle the power better than the RE's. Anways the other question i have is how much room is good to have between the cone and the floor of the truck. cuz i know i should beable to fit the RE's in there but the AA's are going to be tight as they are a bit taller in depth t…

i just went on car stereo.com and i have a 2 cu.ft. box and to tune it to 34hz with the sub being an icon 12 the round port would be 4" diameter and 11.72" long is this right

Can I get away with using a single 4 inch port for my Icon 12? I don't have enough room to get 2 ports in due to the length. Lets assume the box is 3 cubes after sub displacement. Can be made smaller if that is optimal.

Went to competition today out in South West Fort Worth.(Whole new world to me.) Got my single 12" SS SPLX back so I decided to strap both Sundowns to it for 0.5 ohm per amp and let her rip. On my Kinetik with almost no charge last night I did a 151.3 in a 60Hz SPL box. 2.5 cubic foot box tuned to 60Hz with 2 4" aero ports 6 inches long with 1 coat of fiberglass resin on the inside, and the master amp at 1/2 gain. Will post up a pic of the setup and score as soon as I get them uploaded.

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
