Fi Technical

Hey, I'm wiring a 2ohm DVC Fi Q to a Sundown Audio SAX-1200D. Being a monoblock amp I don't know how to wire this properly. I've checked quiet a few of the websites with wiring diagrams but none of them are showing how to hook up to an amp with double connections ++ -- All they show are mono or multiple channel configurations. Currently the sub is wired following this diagram http://a248.e.akamai.net/pix.crutchfield.com/ca/learningcenter/car/subwoofer_wiring/1DVC_2-ohm_mono.jpg Looking directly at the side of the amp with speaker connections, brackets = [wire] [+] + [-] - I think with the way I have it wired that it's running @ 4ohm. The goal is 1ohm.…

Hello all, need some input from the pros. Currently have my Q in a box from obcon (1.25 cuft before displacement) that a friend gave me. The enclosure is made of paperish mdf that basically turns to dust so its time I get a proper box. Now my question is, should i make it for the max 1.5cuft after displacement? Want to keep the notes tight. Also I have it powered with a rockford t1000-1bdcp (birth 1366 @ 2ohms). Thanks in advance for the help.

Just yesterday listening to my system, and my sub went out. I checked all the wiring and nothing looks loose. And I don't think I blew it because there was no smoke when it went out. Is there an easy way to tell if it's blown or not? Or if anyone might know what is wrong here, please let me know. The sub is a 12" fully loaded BTL that I bought this summer. Any answers or suggestions are greatly appreciated. And if there's anything else that you need to know, feel free to ask. Thank you.

I am thinking about putting an FI Q 15 in a 2 cubic foot sealed box. I think that this size is on the bottom as far as recommended. Does anyone know how well the FI Q performs when it comes to small boxes like this?

i seem to recall either FI or a member on here stating to use a Bl or BTL cut sheet for the SP4. i am getting my recone soon and want to build a plane vanilla box tuned to recommended spec to see what it sounds like. what cut sheet should be used with the SP4?

Ok, so i have figured out what i am going to get. 1 fi btl 18 and ma audio HK4000D with pioneer premier DEH-P980BT deck. I need some help building a box, just need a very simple one I have a dodge charger and the dimensions we have to work with are 31w x 14 1/3h x 30depth and MDF 1inch since the height is only 14 1/3 i am going to have to slant it, can someone help me with a drawing or something, like where the top panel needs to slant in order to have enought room to fit the sub please tell me what you think and if you have any advice please tell me. Thanks, Madison

Hello I have a ssd12+bp running off a Alphasonic 1200da at 4ohms. Rms is 1200 at 4 ohms BUT my electrical system is stock so with around 50-70 amps at 12.5-14 volt I believe Im only getting 550-700 watts to my sub. The 12 is in a slotported box with 1.6cuft tuned to 34 htz. I built the box for 2-12 so they each have their own seperate enclosure, but I can not see another SSD 12 in the near future cuase times are tuff. My question is this- If I build another box for my 1-12 at say 2.3cuft with a slotport tuned to 32 htz, what do you guys believe the difference would be? more SPL? I really would like it to BOOM harder, louder, higher spl. Im not into SQ so if that goes down…

Will I be doing a great injustice to my Q10 by only have 600 on it? It will be in a .6 sealed box. Amp is an Arc XDI600. I was trying to sell the sub but cant seem to get it sold, and am tired of it sitting around. So I finally decided screw the weight gain and am going to put it in my T/A. Thoughts?

12" Fi Q with a rockford fosgate punch p1000-1bd Dual 2ohm coil sub wired to 1ohm in parallel 2.5cuft ported box in a 02 Impala tuned to 32hz ------------------- Is this a good setup and how will it sound. I listen to rap & want good sq but also want to blow people away. I also have a couple questions about the setup & about the sub -will it work & are there any changes or other amps that that can make it better for cheaper? -is the rf a good amp? -what component speakers/tweeters should I use? -should i upgrade any electrical (i will go to a yellow top battery already)? -will my alternator hold up to it (i know nothing about my alternator)? -do i need a cap?…

Hello, I plan to build a box for my Q18's (bp option). The box will be 12ft^3 tuned to 28hz w/4 4" aero ports eash measuring 11.5" long. Each 18 will be receiving 1600w. Please tell me if my specs are ok or not. Thank you, Larry

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 WAS WONDERING IF I COULD FIT 2 15'' BTL'S IN MY TRUNK. IF NOT COULD I FIT 2 12'S? I wanted to build a ported sub enclosure tuned to 32 hz. I ALSO WANTED TO KNOW IF THERE WAS SOMEONE I COULD PAY TO DESIGN ME A SUB ENCLOSURE? AND I ALSO WANTED TO KNOW IF HAVING 1 AMP POWER BOTH SUBS IS ANY BETTER THAN HAVING ONE AMP PER SUB (FOR EXAMPLE 2-2,000 WATT AMPS AS OPPOSED TO 1 4,000 WATT AMP? IF ANYONE COULD HELP ME OUT I WOULD APPRECIATE IT, THANKS, IM TERRIBLE AT MATH. My trunk mesurements are in the following link, I wasn't able to figure out how to post the picture. Trunk specs

Hi my name is michael, I am new here and figured this would be best place to get help. I have 2012 fusion, I want to add these 15s I understand the box will have to be built in the trunk and will pretty much take it all up. I will be putting the batteries in the spare tire well. I will be running DC power 270Xp. Min of 2 runs pos/ negative 0 gauge from front to rear and probley the NS-1 amp. I have around 45 inches in length, 18 High, and 25 deep. I have been doing some research and it looks possible and many cars have 2 15s but just trying to get others opinions. I know it gonna be hard but I figured might as well do it right the first time. Thank you for taking time to…

I recently hooked up 2 Fi BL 10's to a pdx 1.1000 connected to the battery by 4 gauge wire. Within ten minutes of playing i had blown the fuse coming from the battery to the amp. I was wondering if attempting to run this setup off 4 gauge wiring is hindering the ability of the system and if it would be beneficial to up the wire to a 0 gauge. Thanks in advance for the help The fuse was a 10GA stinger fuse, switched to a 25A raptor ANL fuse & holder after burning the fuse. I switched because the stinger fuses were too spendy.

Hello everyone I'm new to this and need help.Ok I have a 2000 Buick Lesabre I'm gonna purchase 2 fi bl 15's and use a sundown saz-3500d amp.The question i have is should I get a dual 1 or dual 2? Also what kind of box and components should i get?Any suggestions would greatly be appreciated.

How well will this enclosure work for an Fi Q 10" sub. B

I just hooked up my brand new fi ssd 12 dual 1 ohm sub and hooked it up to a kicker zx750.1 amp and put it in a 2.5 cu ft box tuned to 33 hz. i turned the gain 1/2 way and bass boost to 9db. When i turn the head unit up the sub starts to smell like its burning glue or something. any ideas?

I have 2 loaded btl 12s that Im going to be running a T4k on. I want to use aero ports but the only way that I can get enough port area is to go a bigger than the recommended 2.5ft3. I may have to go with something like 2.7-2.9ft3.....is this ok for daily usage? Or will it hurt the woofer? I see on the Fi site that u shouldnt go any higher than 3ft3. Id be below that but they say 2.5ft3 on this site?

Hello all. my enclosure will be finished soon.. like i haven't a lot of space in my CLK trunk,i have made a 3.6 cu ft @ 33hz box(after port and diplacement... 55 square for the port area). So do you think it's good for daily? (no SPL competitions)... low will be good? good SQ ? value for the subsonic? I have ordered my amp, a "little" Digital Designs Z1 this beast give 4000-4500w/1ohm at 12v.. my new batt is a NSB90(enough for the Z1) give me your ideas,pronostics i'll be back with a video soooooonnnnnnnnnn... ps:Scott,like you have told me,i have dropped my car ....2inch with the total weight

Trying to figure out how to get the 3rd magnet option on the BTL.... I want to say I remember seeing it on their website as an option in the past --- has it become a standard? I only see the following options: Ohm configuration, p chamfer, cooling, hixm coil, daily or spl, induct heat ring, and the universal option. Thinking about getting a fully loaded BTL within the next month. Any help would be greatly appreciated. Thanks. Also, looking to get the AQ3500 amp w/yellow top up front, alt upgrade, along with big 3 upgrade. I listen to a lot of chopped and screwed music, so I think this setup would be perfect. C and S music isn't clean anyway - just good bass - so i'm not …

Hey guys i have a 2009 silverado crew cab. i asked a few weeks ago how to get more bass out of my truck a few of you guys suggested raising my seats to accomadate larger subs and enclosure. that being said i raised my seats 4 inches. i now 3.8 cubes before any displacments. my questions are im looking for the best spl but i dont think ill have enough space for two 12 btls if i port the box. the box is 55 inches long and a port is gonna take too much space. the subs will be firing down into fatmat so i dont think im gonna hear much "music" out of them. any suggestions? thanks

Would 1 10" bl with cooling and flatwind coil in a 1.4 cuft box tuned to 32hz be louder than 2 10" ssds in a 1.8 cuft Tuned to 33hz? Also what would be the ideal port area for the ssds if I put them in a box with two ports? Thanks

well i noticed yesterday when i was listening to late night tip that my sub bottoms out on one of the bass lines... how might i go about fixing this ?? i got a 15Q powered by an hk401sx

This is what i am going to do: 2002 Impala 12" Fi Q dual 2ohm w/o bp option Kicker ZX750.1 2.5 cf^3 at 32hz ported box tubeafter displacement Kinetic battery under the hood Cap Big 3 upgrade **NO ALT UPGRADE** Is all this fine & should anything be changed? Better amp for a cheaper price? Any other suggestions or comments?

I currently have a fi btl 15 fully loaded and i planed on using knu konceptz 8 gauge speaker wire but when i tried to wire the sub up the wires were too big haha...so is there anyway i can make the wires fit ive looked at banana clips and wire reducers but i dont know what to use and if it will distort or loose power
