Fi Technical

so i wired up my 4 fi bl 1ohm dvc subs up to my kicker zx2500.1. have them all wired up to a 2 ohm load(checked with a ohm meter) and it doesnt sound good at all. i get it past quarter volume and it starts to distort and sound like crap. im positive its something in my wiring but i cant seem to find out what. i have no idea how to post pictures on here. i followed a rockford fosgate wiring diagram http://www.dodgetalk.com/forums/showthread.php?p=4204724#post4204724 not sure if im allowed to do that lol but there is a picture of how i wired it on there.

Hi to all, this is my first post in this forum I have some question to ask and i hope to get some answers First of all, i have already checked the "SSD Box cut sheets!" topic but the box measures are too big, but also i read the box must be of 6/10 cu.ft So i ask if the following measures are ok for a FI SSD 18" (i want brutal bass, a huge pressure, feel bass hits my head and also get accorded at low frequencies like 30-33) Box: 6.6 cu.ft Box Width = 27.55 inches (70 cm) Box Height = 19.68 inches (50 cm) Box length = 19.68 inches (50 cm) Air Port height = 11.81 inches (30 cm) Air Port width = 3.93 inches(10 cm) Air Port length = 15.74 inches ( 40 cm) I calculated the m…

My buddy bought a Triple stacked BTL (first gen??) and I currently own the 2010? UFO style BL (without red sticker on bottom of magnet). My main point is will it be worth it to get his BTL? Im not sure how much of a difference the generations actually make but I'm assuming a newer generation BL will perform the same as an older generation BTL. Opinions? Im going basically for SPL and the box is 3.75 ft^3 @ 32 Hz. Please no flaming. Im already one hundred percent satisfied with my BL but just wondering if the BTL will give me that extra boom boom ya know. Ohh, and both the subs are fully loaded 15's and will be ran off of my RF T-1000Bd.

I got 2 12btl. fi recommend 30hz-35hz I want to be heared coming from far what do u recommend and why.

Well, Im planning on buying my fi btl n2 18 aroudn december, near christmas! I have an 03 nissan xterra, so im sure there is enough room for a box in there, but the problem is, i barely know anything about sound systems and their setup/ configurations. If anyone could please explain what i would need, i would appreciate it. Im getting a new double din headunit, 2 door speakers w/ tweeters, (Which i will wire to the headunit) I plan on getting the n2 18 What amp, would be best to run this at its best performance daily? I won't be going to competitions or anything. If you can please let me know a couple good options that arent super expensive, i am not on an unlimited budg…

I need dimensions for bl 15 ported box?? I have a hifonics bxi 2008d amp to go with it. and this setup is in a 2001 dodge ram 1500 sport, so the box needs to be on my back seat. any help will be appreciated. thanks.

what gauge speaker wire would be recommended for 4 10" fi bl (flat wind coil, cooling) i have 12 gauge speaker wire but im thinking that that is too small. its kicker shielded wire. would i be able to tie the 2 wires together and double them up to have roughly 8 gauge wire? or is the 12 going to be enough?

What's the best way to solder the tinsel leads onto the terminals with these new recones that have the leads coming out of the spiders. There are 4 lead wires for each positive and each negative. I think its obvious I won't be able to fit them through the ring on the terminal, so how should they be soldered? Should some slack be left?

my cousin has two tc9 12" subs that are blown. We were wondering if we could order baskets for 15" SSD recones to fit on the magnets. As far as the mounting screws go, they should about all be the same mounting area, correct? Do you think this would work, right recone?

I have attached a photo. the leads where built in but need to get this puppy rebuilt. I had my installer rebuild all 4 of my 15" and one took the dust. He had told me he ordered off the FI site but can not find the options he told me my subs had. From what he told me Dual .7 coils 3 back stiff coils 2 yellow (one with woven leads. i belive there wher 4 leads per post each. blank dust caps. reg fi cone and foam surround. My subs are the dual stacked. I have attached a photo. Thanks for the help. 154.00 @ 29hz

Does anyone have the TS parameters for the Black Fi-Day X, specifically the 10"?

ok heres the deal im wanting to buy two 18's for my truck and want to know if the btl n2s will fit. I have an 01 ford f150 supercab which is just an extended cab 4x4.What i'm wanting to do is build a wall basically take the whole back seat out and build the enclosure in the truck.I am going to apply dynomax deadner and i have a pioneer avic z130 bt head unit and going to purchase two kicker zx 2500 amps and two yellow tops cause my trucks battery is almost dead anyway also going to get a bigger alt. or possibly two.Have already bought power acoustik mids and tweets.all going to be ran with 0 gauge.so basically i want the btls but dont know if they will fit because of the…

Ok so My FI BL 12" just arrived, i had a 18" previous in my Ford explorer. Now since I have a 240sx i need something smaller. I have my amp (saz-1500D) all set-up and ready to go. I forgot i need to reset my gains because when I tested the sub I could hear it clipping, and for some reason my gain (min/max) control knob mounted at the front of my car did not change the output of the sub. I lost the original cord but i read a phone cord could work so i tried and the blue led works at least. I digress to my problem which is that i forgot how to set my gain. I remember sticking in a 60hz cd at 3/4 full volume and reading the voltage from the amp but i forget the calculation. …

Okay so I'm going to recone my Q series to a dual 1. Its an older Q d2. I'm running a mmats d300hc to this woofer in a closed box about 2.5 cu ft. I love low bass. I want a recone config good for everyday driving and music. Mostly rap. Go with flatwind? Or copper? I want some leeway to have some fun so should I go with bp options for cooling? Enclosure reccomendations? About to order this shit tonight confirmation in the forum would be optimal

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?

Does aero style ports still fall in the recommended 12-16 CBF range? Was thinking of a single 10" in a 6cbf loud daily tuned around 32-33 range or maybe 2x7" what do you guys think?

i. I have an old Fi Q that I need to get reconed. When I cut up the soft parts and cleaned up the basket I. Saw it had "Q D2". I figured that would give away the time period in which it was made. I was wondering the power handling of the magnet, as I was thinking of reconing it with a BL recone kit. Could I do that with a Q magnet? I have a mmatts d300hc reconing it to a dual 1 would be my plan. Could the BL recone work with this magnet?

So, I've got a question regarding the power handling capability of the X series 15" sub. I'm building a Tapped Horn that's going to load the sub down at 25hz and 60hz. I am expecting to see maybe 5mm excursion @ 400 watts at those two frequencies with a max excursion of 14mm @ 30Hz. My question would be, in your guys' opinion, will I burn up the VC because there won't be enough motion to cool the coil off? This whole project is a bit of a technical practical to see how low and loud I can go. The tapped horn should give me excellent low end extension into ~20Hz and keep the coil in the gap @ 400watts. Just wanted your guys' opinion on the power handing capacity. Thank…

Hey guys, told you I'd be back ... lol ... I recently had the post concerning the enclosure design for the SSD 15 and got that all figured out and taken care off. it looks so sexy with it in the box! Looks like it belongs there lol. Well the Fi sub came in today and I've ran into a problem, and I'm pretty sure I'm going to have to recone it already within the first 5 minutes of play ... First off let me start off by giving some info, the box of course is tuned to 32hz, I do NOT have a subsonic filter. I was warned of this and my hardheaded self didn't think it would screw anything up that fast. (Almost instantly, bout 5 mins of play time.) The sub is a dual 2 ohm…

Buddy of mine has 2 bl 18's ran off 1 sundown 2500d, he has them in slot port now in about 12.5 cubes gross. They sound decent, but dont really have the lows, and its tuned to 32hz. He wants new box with 4 6" aeros's in about 16 cubes net tuned to 32hz. How does this sound for size? I ran 2 bl 18's about 2 years ago off 2 sundown 1500d's in about 18 cubes net with slot port and they pounded the lows, and sounded perfect. I just havent done any builds with aero ports.

So im about to order two fully loaded BTL 15's and Im trying to decide whats the best amps or amp to push them to the max. Right now im looking at 2 kicker 2500 or two rockford 2500. Any suggestions?

Ok guys heres the situation. I ordered a BL 15 with cooling and flat wind dual 2 ohm. I'm building a box myself and having trouble on what to do with the port. The box is planned at 3.76 ft^3 with the woofer displacement added in. Its recommended to have 12-16 sq in of port per cube so i need anywhere from 45-60 sq in of port. I want to just maybe slap a 3x6 aero port or maybe a 4x6 aero port. The 3x6 is 42 sq in and the 4x6 is 75. Both not in the range i need. Also looked on amazon and found precision ports 3 in and a 4 in round. Doesn't say the length on them tho . Reviews say there adjustable somehow. Help would be appreciated. Also wanted some recommendations on ampl…

i would like to know what is causing my sub to get to the point where i smell voice coil.. the sub is a 08 15" bl flatwound coil p chamfer in a 3.4 cubic ft box tuned to about 42 hurtz. Could the box be to small, port not proper size, lenght or could i be pushing it to hard? I am running jbl gto 1400 at 2ohms thank for any and all input.oh yea sub is d1

Hello all, first off let me say I am new to this forum, and hope to enjoy my visit here. I just recently bought a Fi SSD 15" sub, on the 16th or 17th and I realize it is probably going to take forever (or what feels like it ) to receive it, and the wait is already getting to me as I used to have Kicker CVR's and they died and so currently I have no bass! Ahh killing me hehe, so therefore I decided to take a bigger step up in the world of bass. My question is, I am in no way, any good at enclosure building, I mean I could put together a sealed box but who can't? I need a ported enclosure, and while I understand what tuning is, I have no idea mathematically how to figu…
