I think its dumb people are abusing the rep system. The rep system is so people reading can tell that the post is informative or not. STOP -REPPING HIM BECAUSE YOU DON'T LIKE HIM. Someone gave him a -rep from quoting my post lol. Wtf.

Where are you gettin optimas for $30? I found a stinger SP2150 on Clist the guy is asking $300 I think its 91 ah Is that even a good buy used for $300? $300 for a used battery?? You can get a new one for $340 shipped. Anyway, the cheap battery trick has to do with the manufacturing date. All batteries made by Johnson controls will have a round sticker on them showing the date of manufacture. Find one at an Auto part store that is one year old or older in manufacture. Most Auto chains will not sell you this battery at retail if the worker is educated in any type of business practices. When the battery is over a year old, they have a choice of sending it back, (just to be rebuilt) or selling it as a "used" battery. Instead of losing out on all money, they will change the sku number on the "old battery" to a used battery and sell it to you. I know for a fact Autozone does this (I was store manager at 2 stores) and O'Rielly's too. If you live by a low volume store just go in one day, ask them about used batteries, look at some manufacture dates, see what you can come up with. Another neat battery that chains have you could get "used", is the Mazda Miata battery. Really cute, really small, perfect for a clean simple install with little power. I'm actually buying another D31 from O'reilly's today and will gladly take pics and post a receipt if people don't believe companies do this....

Technology has improved greatly over the past 20 years......however the laws of physics remain the same, which is what we are battling in the realm of sensitivity. An article on sensitivity can be found here (and was also linked in my post in the DVC thread) that will provide the answer to your question: Subwoofer Sensitivity - SSA Car Audio Forum

I don't know what your problem is, but when I click on the link, I'm given the option of seeing it full screen. How to post pictures in a thread - SSA Car Audio Forum

146.6db, 37 hz, 108 degrees outside in the new prototype enclosure

Yes, a supergauss motor.

Now this post is the beginnings of something never attempted by myself nor my son. Ever heard of 10lbs of crap in a 5lb bag??? Well we are attempting to put 120lbs of crap(just a figuire of speech) in a 20lb spot. We have come to an understanding that because of space limitations we have to make some choices on a happy medium between looks, space and performance of the products we have chosen. So, that being said we have come up with a design that should give a nice wow factor and still have decent performance. We also were trying to make sure that all the tail-light and such were accessable once everything will be installed.(Don't want to tear out the system to change a bulb.) The looks of this box for the 15" sub is really scarry. By sefugi at 2010-06-05 Mock-up of the 2-10's and the 15"--Not to sure at this point...Does seem to have an ok flow from one to the other... By sefugi at 2010-06-05

If you are only using a single coil of a DVC driver and leave the other coil open Qes and hence Qts would double, sensitivity would decrease by 3db, motor force (Bl^2/Re) is halved, the inductive corner frequency doubles and power handling is decreased (some argue that power handling is not cut completely in half because the 2nd coil helps act essentially as a heat sink which helps dissipate some of the heat, but I've never seen any testing done to confirm power handling of a single coil compared to both coils). I found this link by accident one day a couple years ago, and it shows a good comparison of a driver's change in T/S parameters with coils wired in series, parallel, one coil driven the other shorted (for both coils), and then one coil driven and the other open (for both coils); woofertester.com If you are interested in the math of why the above happens, you can skim through the formulas for the T/S parameters here on Wikipedia. Resistively Damped Operation can be accomplished by only driving one coil and using a resistor or potentiometer across the 2nd coil to "change" the Q of the driver. This was the entire premise behind the old Ascendant Atlas driver. Yes, they really are. If you want to calculate the efficiency of your subs (or any other speaker), you would use the formula found here; Efficiency (N0) = 9.64 * 10^(-10) * Fs^3 * Vas / Qes *To express as a percent, multiply by 100 *Vas in liters So, for example the Efficiency of a 12" SSA Icon is; 9.64 * 10^(-10) * 29.9^3 * 43.7 / 0.45 = .002502 .002502*100 = .2502% And to verify, to convert this into SPL 112+10*log(.002502) = 85.98db And the sensitivity of the SSA Icon according to their specs; Spl 86.0 1W/1m TaaDaa!! So the SSA Icon converts .25% of the power you feed it to acoustic power, the remaining 99.75% is spent as heat.

If your looking at the Havocs, you may want to look into the XCONS here .... http://www.soundsolutionsaudio.com/index.php/product-information/xcon.html I hear they are pretty good ....

O.K. We all have our jobs. To take a break from sanding my son worked on the front and rear bumper. Had to cut and fit the wire mesh to fit in all the holes that are cut in them. He also wanted to add some support rods to the front bumper for strength. This is the rear bumper with the screen cut and fit in the bottom holes, one side will have to be cut out for the muffler to fit through. Oh! Yes those are headlamps wired and modded into the back-up lights. His idea, I guess he needs more light when he backs up. By sefugi at 2010-05-30 Untouched front bumper. By sefugi at 2010-05-30 Support Rods and screen installed. Starting to look good. I might even drive this thing! My son says By sefugi at 2010-05-30 By sefugi at 2010-05-30 By sefugi at 2010-05-30 Thanks for looking, will continue to move towards getting this together a peice at a time.

Another day is drawing to a close but we have made more progress. I'm so tired of sanding. Originally had a couple guys that were going to do the body work and paint the car, but you can't count on anybody anymore. So all the preping that has been going on was not suppose to be in my lap, but now it is and we are doing our best. It's coming along but it sucks. Here's a few more picks of the progress. Got the side-skirts mocked up. By sefugi at 2010-05-30 Then got them primed. By sefugi at 2010-05-30 Front fenders primed. By sefugi at 2010-05-30 By sefugi at 2010-05-30 Started wet-sanding fenders. By sefugi at 2010-05-30 Finished wet-sanding fenders. By sefugi at 2010-05-30 Anybody wanna help sand this thing???

OK, Got the headliner installed. Made some mods on the B pillars cause the factory seat belts are out, will be using a set of 4-points. The B pillars will make more sense once I get the carpet and rear seat installed. Did a quick mod on the rear speaker mount. Factory speakers were 6X9 and we liked the 8" coaxial that O2 Oxygen offered so we made them fit. Once the rear panels are reinstalled the back will look factory, but have a little twist. Stay tuned for more.....Lots more comin' By sefugi at 2010-05-24 By sefugi at 2010-05-24 By sefugi at 2010-05-24 By sefugi at 2010-05-24 By sefugi at 2010-05-24 By sefugi at 2010-05-24 By sefugi at 2010-05-24 I have seen a lot of veiws on this build but few have replied. If you got comments (good or Bad) let um fly. Interested in what people think!!!! or

i know...i understand there are many things that can change the answer....i would just like to know how far other fi bl owners have pushed them in what ever install they may have... so i have a greater overall unsterstanding of the sub and what it can do....when installed right....or wrong.....i myself am happy with the 140 db. im getting out of mine and would only take it past that if i had too....comp....out bump a JL...beat up my car...ect ect...

Since the center console has turned into a switching station we opted to mount the bass knobs for the two sub amps in the console as well...Wont be installing the center console in car yet, waiting on carpet to show up.

i just got my fi bl 12's in the mail and unpacked...in the screw holes of the sub surround there seems to be foam or some type of material blocking the screws path to the box... should i just force the screws through or is there a mistake in the build of my subs???

got my box in and everything is gravy...... will have pics of head unit under the hood batts amp ect.... coming as soon as i get them

and as i said it was np....affter looking at the sub with the surround off it was clear to me... and the extra glue is a good thing.. i just more or less posted the question with haste....and then waited for an answer even tho i was thinking just drill them out...

i really dont care about my rep...to me that show how stupid you ppl are...-rep for 150 db. ty rly ty... dont change the facts tho does it lol at that, most people here know my GF...... At least I'm not the only one who hates you. Yours: Reputation: -25 Bad Mine: Reputation: +11 Good

o i do what i told and learn from it.....but in a town of 14k ppl....we dont do alot of big stuff.... anywho none of this matters....and yes as a matter of fact i did need to know that.... and not talking down on fi here but there was a good deal more glue built up in the screw hole than i had ever seen and the surround was crooked so at first that was a bit strange too me....but it was np at all.........buck up your buddy and his slander...and doubt me if you want but as we speak i am uploading proof lol try and put a system in the back of a van..... see how loud you are then. I am pretty sure if I put the same system in the POS you drive, it'd break the car while do 55's lol. And we all know your lying man, just chill out. I'm not going to say your lying, although I think that you probably are. I just find it odd that you supposedly work in a car audio shop: Best way to learn how to install your own car audio - SSA Car Audio Forum Yet, you don't know what to do with a new sub: screw holes in fi bl blocked with foam?? - SSA Car Audio Forum Something doesn't seem right here... Maybe he sweeps and cleans the bathroom?

well listin trick mabe you should go get some more db. out of your setup....or get a hug from a female feel me....you being a flat out hater....and right now the only one out here lying is you......every time you fix your brain/mouth to type/talk this ...... this....what i can only call slander.....now sit back and shut up fat boy...and wait for the video i will have my proof by nights end and then you can make up new reasons to hate yourself lol try and put a system in the back of a van..... see how loud you are then. I am pretty sure if I put the same system in the POS you drive, it'd break the car while do 55's lol. And we all know your lying man, just chill out.

lol try and put a system in the back of a van..... see how loud you are then. I am pretty sure if I put the same system in the POS you drive, it'd break the car while do 55's lol. And we all know your lying man, just chill out.

i will have more pics like of the sound proofing batts amp ect later..... but by the nights end i will have my TL posted... until then this fat boy needs to go have himself a cookie

and also no one has thought of telling you that you look like shit in all that green keep running your damn mouth....your setup dont hit and you are but hurt...bottom line...take that funk out of here

No one has thought to mention that the TL can be modified to show higher then true numbers simply by adjusting some setting in the program.

with the box facing the front of the car....and no i dont CLAIM anything....i only relay what the TL says... Claiming 150's with that?......

word i got it

much thanks

you i dont need to hear from until my TL is posted....you have proven yourself to be of a very weak cloth........bottom line... and also i have no idea how to post videos and pics on the threads due to the fact i am new here........ I would say, your stupid and can't handle using links the proper way. And not everyone can access your gallery. Fool

I would say, your stupid and can't handle using links the proper way. And not everyone can access your gallery. Fool

thts crazy im looking at the pics right now...and they have views on them...i would say...somthing is messin up on your end

its a link to my gallery in my profile.....it still works when i click it.....but you can see the same pics in my gallery........150 on TL video coming soon

Yeah, I had an 18" xcon walled. The Xcon is in perfect shape sitting right beside me in my room. The wall that the Xcon was in was about 3 years old and the mdf on the port started splitting while playing woofercooker by bass hit. So, I was like F it, the Xcon is a ""SQL"" woofer, so it can't be that hard to make a louder setup. The opti's have a lot more car flex and feel louder, but on my meter I'm about 2 db quieter than my xcon was. I still need to seal off my wall, and I need to brace my port, the damn thing flexes like galloping gertie. I don't know what to do with the xcon. I really wish I had a 15, not a 18. I'm also pissed at SSA for making such a great woofer. For something that is not made to get loud, it can do it pretty well.......

i have another buddy looking to get a 18 inch btl and he wants to build the box before he gets the sub.... seems like a bad idea to me lol dunno why but i would like to know how much sub displacement to account for when building the box for a single 18 btl... he refuses to listin and jst gets all pissy when i tell him to get the sub first then make the box to fit it.... so before he does somthing stupid i was thinking maybe this info could be found here.....

150.7 @ ??hz And where at? and what in? Who what when where how? Never post on SSA again......

no.............. i put the meter in my box behind the sub

i had the front windows down about 25% i may be wrong but this may be called midwest style

no nothing like that...it was legit....other than my box facing me and my window cracked....both give me a boost im not going to lie... but for some time now i have been trying to beat the 145. put up by 2 mojo 12's in a car that to my knowlege was not even sound proof'd ok weird... cause i was thinking if you had the lab running while you slamed the door with it sealed it would put up a good number if your car was mega sealed i have seen that happen before... also i have seen the wire come unlugged from the mic causeing a huge spike in number.

Sundown SAZ-1000D Sundown Audio - SAZ-1000D Best amp on the market for your sub! You won't be let down. If you dont have the money for that I would look into Audioques 1200D Audioque: Amps: AQ1200D Sundown>Audioque

there are only pics of my box and subs right now...all tho on the same phone there are also pics od my eclipse and my big 3 amp and batts...but i dont have them posted yet waiting for my buddy to let me get them.....but this would not prove my tl...as i said i will be here for a long time too come...and will get everthing posted in time

more than possible its fact....it seems to me some ppl did not hit 150 and now im taking heat but it is more than ok....i will turn the other cheek....i wont hold any grudge when all is said and done

they guy sticks in to my driver window on the passenger side....... and i know the power was dirty.....but i do run a clean 140 db. i have heard i can get a bit more at the kick....but also from what i have heard that does not count.. also i heard windows have to be up for it to be how it would be done in a comp...not sure if this is true and i am not running them like this daily...it was no more than 60 seconds....i dont want to blow my subs...but i have faith in fi's products...and no harm was done....just got a lil bit warm

if im not trippin the TL mic is the lil box stuck to my windsheild right? come again>?

port was center to the car in the back...the mic was in the front passenger side...so i dont think so...but there is a good deal of air so i cant say for sure...i can always feel the air tho... come again>? yeah no it does we were typing at the same time... the time line for fucked... and the port was not lined up with the mic? like where the air moving was of course blowing right on the mic?
