Fi Technical

currently running a sundown saz1500 powering a fully loaded 12in fi bl in a 2.5 cu ft box tuned to 34 hz. I was recently at a local audio shop and had the main guy set my gains properly so i did no have any clipping. I was not very impressed with the outcome. As i come to find i had been running with clipping since day one and my system is now quieter. He told me to tune my box to 40-42hz and it would be louder. My question is how much louder? and will i still be able to play most rap music? What would be the lowest tone i could safely play?

Can someone post a blue print of a ported box for this. my friend said someone was going to build me one for the past month and nothing has happen yet so i figured if someone could just post a blue print i could build it my self i was looking for something tuned around 33 hz. can someone get me dimensions and all that good stuff. thanks for hepling.

Would you guys suggest tuning a BL 15" to 28hz? Has anyone tuned their box for one that low?

ok wat up guys i just ordererd a 15" bl flly loaded BUT i chose the extreme lead option and wasnt aware that this was for spl applications only and not for daily my question is what is going to happen if i run this option daily? my setup is 92 hatchbak mustang with a brutus hifionics 1606d and da bl 15" ,Thanks

Ok I'm planning to run a 15" BL in my trunk and was wondering what box idea would be louder. 1. A regular ported box facing the rear. 2. Wall off the trunk and have the sub facing the cabin in a ported box, with this setup i could make the install look nice with the box i would do the plexiglass with mirror inside of it with some L.E.D. lights in it or something to see when you pop open the trunk with the amps on the floor with a false floor, itd look real nice but it gotta sound good too...would that way be louder??? and my seat fold down if that has any factor...thanks

Well just in the past few days I have noticed that my sub was not working. Me being the lazy person that I am put it off for a while assuming that just a connection was loose. Yesterday I finally got around to taking a look and all the connections outside of the box looked fine. The amp (sae-1000D) looked to be working fine, but no movement or sound from the sub. With the music playing I pushed the cone a little and then it made a little effort but once I moved my hand away it did nothing. This was initially, but today the sub does nothing at all, even when I push on it. Still not sure if the amp could be damaged, I connected another sub that I had laying around and…

FI website says 5-10 cubes is the recommendation. i will have 1500w on tap and am wondering, what is the difference between the 5 cube box and the 10 cube box. obviously the 10 cube box will be more efficient etc etc. but im more concerned with whether 5 cubes is really going to be enough for an 18? most people build 8 cube+. biggest i can get is 5.5 to 6 cubes, is that size box really enough? anyone with particular experience with this would be especially welcome.

I have a 12" BTL with pole chamfer and my Memphis MCD2500 amp is coming in soon. I want to get everything ready so when the amp arrives I can install it right away. This is my mustang 2004 stock electrical: 130-amp. heavy-duty alternator 540 CCA heavy-duty battery Battery amp hours (58Ah) Battery-rundown protection I will be doing the big 3 wire upgrade with 1/0 gauge wire from batt to alt to ground. Besides that, what else should I invest in? I'm trying to keep it as budget as possible. Thanks. PS> This is my daily driver.

Im building an enclosure for a Bl 12 I would like to tune it to tune it to 32 Hrz only Im not sure how to get the results Im looking for the specs for the enclosure im building is 16" deep 53"wide 8" tall on the back side and 9.5" tall on the front side I plan to fire it up I will be running it 1 ohm with a T1000 fosgate amp can sombody tell me what size port and length to use round or slot pot ? total air space is 2.79cuft with 0.18 deducted for sub displacement its 2.61cuft

The car is a 2001 chevy blazer(SUV). I dont want to take up my whole cargo space for this single subwoofer. I dont know wheather to go with sealed or ported, what would be the pros and cons. Would anyone know an estimated demension size(hight,width,dept) i would be expecting to get with either ported or sealed. THNX alot

i got a 15 btl FL dual 1 ohm i need a good amp or amps no more then 350 dollars i have 1 sae 1200 on it now but my buddy is going to buy it so i can get something bigger any ideas???????

I just bought a 12" Brahma MKII, its working but has had the tinsels resoldered after they broke. I was going to attempt to repair the tinsel leads and run with it like that, but, the guy I bought it from originaly said it was a 10" , now he says its a 12" , so I want to go ahead and recone it down to a 10". So, I want to go ahead and place an order for a 10" recone kit with 10" basket and gasket shipped to 26851. Just wanted to post this here before I send any emails.

I'm just curious as to why the Universal option isn't on the subs by default? It doesn't cost any extra money, yet i do not see any disadvantages of having it done to a sub even if you do not want it. So... is there any disadvantage of having it even if someone doesn't want it?

ok so im going to be running a 12 fi bl on about 1300 rms...which gauge should i use 4,2, 0.. i have no knowledge of amp gauge wire so anything will help...

I opened my trunk this morning to find my Q15 had puked out a fairly hefty metal object and blew the dustcap off. I believe this happened listening to the sub well below tuning freq. (tuned to 30 hz. and playing "late Nite tip" by Three Six Mafia) What is this piece of metal and what purpose does it serve? You could stick your hand through the middle of the sub and this piece would have prevented that from happening. If this can be glued back in what do I use? CA glue? The sub still works but i want to fix it before playing it again. Thanks in advance for all of your help!

how much max RMS watts can a 18" fully loaded BTL N2 handle ?? i was wondering if i can run a 2400 watt RMS hifonics amp to it ?? also will a 6 cubic feet box ported to 35 hz sound good ??

all hooked up to a good electrical system should i run the amp at full tilt or dial back just wonderin if the sub will take it for a daily beating and last

hey i was just wondering what would be a good amp to run 2 18 in BTL off of for my 2002 chevy avalanche and does anyone know if everything necessary will fit? right now i have 2 12 in alpines back there.

Im looking at buying a Fi BL 15, im going to run it off a 1700 rms amp. i dont know what opions should i get. i was looking at the 4" coil. i think that makes it 1500 watts rms i heard but im still undecided. little more opinons would be helpful.

So I got 3 15 in dual 2s wired in series tuned to 33hz on an audiopipe 30001d amp isn't turned up a little under half no clipping and as normal subs gets a little warm never hot enough to where u can smell the coils burning up. Now my issue i ran into today Is I was listening to them going to lunch with no problems and shut the truck off and came back out and just turned system on and how I can describe it is one of the subs instantly started to make a distorted rattling noise... kinda sounds like the sub is farting all lower frequency but not noticeable at higher frequencys. I pulled speaker out and the coils dont have any noticeable scratching or rubbing.. Now I'm just …

I'm getting ready to build an enclosure with 2 BL 15's in my 06 Civic and was wanting to know what frequency would be best for both daily and competition.

Hey. I am doing a 5.5 ported box in a hatch of my 1995 camaro, off of a hifonics 20006D, What Sub(s) would you recommend? I want the sub to hit the lows and be pretty loud. I was thinking a 18" BL. Tuned to 36-37. Or maybe 2 15" SSDs? Not sure if these subs will be suffocating in the box that is 5.5 without displacements.

I'm the one with the konaki motor ! Please recone it. I've sent you guys emails and nothing yet. Its been almost a month. Give me dual 1 18" with the strongest softparts available . K-thanks bye. My email is [email protected]

just got a blow sx 12 and the glue on the top plate gave way when i pulled the coil out, so the gap collapsed, is there anyways to realign it, if so how much. thanks

Ok I have a x 10" with single magnet structure. Svc 4 ohm. I need this sub to be a svc 2 ohm and have a small tear in surround fixed. I have emailed fi twice on this and gotten no response. Anyone know how much it would cost or anything about reconing this?
