How is this for 2 15 bl's? http://www.subwoofertools.com/forum/ported...mp;Fs=&CE=0

which of the old 3 slug options were cosidered basically universal, D1 or D2. i bought my btl from teampsi on ca.com, on his ad he said its a D1 so its basically universal. i have read else where that the D2 were the ones considered universal. can anyone clear this up? im about to order a recone, and i want D2's but i want to make sure it will fit! thanks fellas

Does anyone have or know where to find a wiring diagram that shows how to wire a single 1 ohm sub to 2 ohms?

hey i have a question for anybody who can answer, i am installing a 18 fi bl in my 01 sonoma my intent is a daily driver with occational spl comps. My box is 48 wide by 24 tall by 13 deep that comes out to about 6.9 cu feet i believe but i dont know how to figure my port size ? Needin some help

Ok so here's the deal. This is my wall design for my two 18in. fully loaded btls that will be running 3000rms a piece. I have never done a wall build before so I'm hoping i somewhat got it. EVERYTHING is double baffled 3/4in. mdf . In the 1st picture showing the front plate it looks double baffled its only supposed to be single " which i just fixed and im to lazy to take and upload another picture" due to the fact that there will be another front vanity plate to go around the curves in the car all nice and snugly. The box is , 15.7341 ft³ BEFORE DISPLACEMENT 15.2141 ft* after sub displacement displacement port is 6 inches in height width is 29.224 in…

well as u can see i have a kicker zx1000.1 rated at 1258 watts. which i do not have installed in my car yet which is an 02' dodge stratus R/T coupe, and i think it hase either a 85amp alt or a 90 amp alt. And im also goin to be buying a 15" BL w/ the p chamfer i already have the big3 upgrade done with elemental designs 1/0 gauge wire will i have to consider on upgrading the alternator?? ive looked all over the net, and i just cannot find one for my car, so i need some help on that IF i do NEED to upgrade and wat about mabe a battey or 2?? thanks

i would like to know the dimensions of what 5-10 cubic feet is...im not a math whiz sorry. i would like to know roughly how long and tall it needs to be to meet 5-10 cubic feet. thnx so much guys, mike

hey guys , i recently ordered 2 15 Q's , am going to run them off of a single SAZ-1500D , with 1500rms to both subs. i want to build the box before the subs get here , and had to ask for advice i noticed on the Fi website that the recommended size for each Q15 is 2-2.6 CF. i can give each 2.5CF . will i get good lows? will i lose anything? not enough power to them? im not planning a LOUD LOUD system .. just loud and clear;) thanks. Eli.

My amp is going to be a 1500d, for sure. Two SSD12s have a recommended ported volume of about 5ft^3, and a BTL15 has a recommended ported volume of about 5ft^3 as well. I understand the two 12s will move more air, which may be more impressive as far as my budget will go, and being realistic, I don't anticipate being able to buy another amp or the surrounding electrical to back it up for awhile. Anyway, I ask your advice once again. Should I go with two SSD12s or one BTL15 powered off of a 1500d running at 1 ohm? If built in their ideal boxes, which would get louder, or would it matter? What would be the pros/cons of either? Mahalo, Trevor

I have been told the 12 ssd weighs 25 pounds, i was curious what does a stock 12" Q weigh? Just curious because i might get one if i can sell my 2 12" HCCA's old schools.

Hey everyone, So i recently sold my 2 audiobahn 12'' sub woofers, and my amplifier. I have the money now to buy my 15''BTL fully loaded. I had a few questions that i am still not sure about. 1.What should my "ohms" be if im using a mono amplifier. 2.If my box is tuned to 3.25feet at 30HZ is that too little feet, and too low HZ? 3. Does anyone know a good mono amp to go with 1 fi BTL 15inch 4. Also is a BTL legit 2000RMS? i really aprciate all help, thanks everyone.

Will 2-18'' BTL's be happy with 2000 watts per sub? And will they play with 2000 watts each or do I need to put 4000 watts per sub? Need to smoke 2-13" w7's. Can 2000 watts per sub do it???

I was wondering if 11.25 net tuned to 31hz and 166.25 square inches of port is too much for 4 fully loaded 12 inch BL subs running off of 6,000 watts of power?

Hi, Ive got a MTX TA81001 amp that pushes 1500 watts at 1 ohm and im going to run a 15 inch Q. Do i need to get the BP option or will it be fine without it.

I'm looking for someone to build me the box specified in the "BTL Cut sheets" thread. I have the Fully loaded 12" (2010) model BTL sub. I would like to know how much it would cost (both for the box and shipping). And I like to find someone who has made these before and knows what they are doing. If you can show me pics of your previous work that would be great. I would prefer it if you had a PayPal account as well. If there is anything you need to know from me, let me know. Thanks for any replies.

Hey, This will be my first time buying FI subs and just had a question about what I should buy. I was gonna get two 12" FI BTL's and power them with a Sundown SAZ-3500D amp when it becomes available. Under the amp specs it says: ----RMS power, 2 ohm linkable/dual mono 6000W x 1CH ----RMS power, 1 ohm mono 3500W x 1CH I'm confused as to what the difference is would I be able to get 6000W to the two subs if i got the 2ohm versions? or should I get 1ohm? If I can only get 1ohm will 3500 be enough for two of those subs or would that be very underpowered? Any recommendations on the box size and port size would be greatly appreciated as I will have it made by someone. I'm …

Ok I am about 10-11 months from buying a 2009 Mini Cooper S (waiting because I will pay cash) so I have started my plan for the low end. I have a 10" BL on the way and plan to run it of of a Fosgate 25 to life Punch 150 (birthsheet states >800w rms) I want to keep the box small but want good bottom end I am looking at around .5- .7 ft^ Has anyone run the BL in a small box like that? Any problems or chalenges? I can go larger if need be as the car will not be a grocery chaser but my commuter car BUT I want to still have space in the tiny trunk area for the times the wife and I need to put something back there. As you can see I have time to change the plans but the BL is…

Hi. Im from Romania and i bought 8 or 9 months ago a FI Q 12''. As far as i know there are 2 speakers sent in Romania A FI Q 12 AND A 15. OK i have a little big problem with my fi q 12 sub. the spider has unsticked , or broked , from the center of VC or how is called in english and that makes the sub scratch if i play music. i stopped the music since that day cuz even if i slowly hit with my finger the surface is does pack pack !!! oufull sound. and... i expected more from Fi ... i never tought it will broke. by the way the voice coils are intact. tHE power that the sub recieved was 900 w/ 1 ohm . thanks ... i hope u can help me. http://img76.imageshack.us/my.php?image…

will a 4 cu ft box all one chamber tuned at 32hz be ok for 2 12 Fi Q? or do the chambers need to be seperate for each speaker? thanks

I need help on how to fix my torn surround. Can I get a replacement from Fi and repair it myself or do I have to send it in? Is there a proven way to fix a tear in a foam surround other than shoe goo? Also, can you determine the options a sub has without tearing the speaker apart? Thanx guys.

hey i got some cliff designs cd120c and im looking for recones need to handle about 1400+ rms they will be on a rd 1750 for now but im upgrading to a sundown 3000d. got anything. pics thanks

Just placed an order for my 15" BL Anyone willing to help me with a box design? Trunk Dimensions Estimating: 36 x 36 x 18 width = 36 in. length = 36 in. height = 18 in.

not sure if this is the right spot to ask, but would 2 stock SSD's be ok on an AQ2200D?

I am going to be ordering a 10" BL and was wondering which to get? Should I go with the dual 1 or 2 ohm? I plan on running it off the saz-1000d. If I get the 1 ohm, that would bring it down to .35 ohm, but with the rise, shouldn't that bring it back to almost 1 ohm? Just wondering as the amp reports that it is only 1 ohm stable. or would it be better to go with a Mmats 2100.2 and get the 1 ohm and wire them in series? this isn't something I need ASAP, but any ideas would greatly help the process. Or... another option is to go with the dual 1 ohm wired in series and go with the saz-2000d. Ideas?

Hi, i've been passive for a few months right now. My last system was one 15 btl dual 2 on two RF t20001bds @ 2 ohms with few kinetiks and 300 amp alt. I think of adding another btl 15 but keep the amps, one btl strapped to 1 ohm and one t20001 @ 1 ohms per sub. Do you think this would hit harder or should i just recone the current btl to dual 1 to use the full power of the amps.... Patrick
