General Fi

So I've decided to get a sundown SAE-1000D to go with a 12" Fi Q and I have one question before I go ahead and order them. For the sundown amp, do I want to order the Q with the dual 1 or dual 2 ohm option? And would I need the BP power option as well? Thanks Ryan

I ordered my Fi sub about the beginning of this month, i was wondering when will i get my sub. then i get a call about my sub being delayed, man!.. missing my bass.... wondering how long Fi?

after changing from goin bl to q...i wanna kno if i can still compete with em and still be in the high ranks(high 45+db)..if anyone has done it ...specially with a pair of 18 q's lemme know your score on TL and your enclosure specs...i have a an old(tricked out)corrolla hatch back...enclosure designs for optimum output??,..thanks!!

i need two amps to power 4 15 btl loaded. i want them to be clean power, low voltage, stable at 1 ohm or lower, be able to get 2k-2.5k a piece. i will be entering in spl comps and need something that is going to stand out if ya know what i mean? i want mid 150's, this is going to be in a nissan p/u truck ext. cab that i am going to put a camper shell on and have it walled in! also what does everyone think about the z-1, i have concidered 2 of them because the are 12.5 volt required and the are strappable.

Okay everyone I am going to order later this week and I need to make sure I am doing everything right. This is my first system. I mostly listen to rap but I like rock too. Its going in a '97 tercel. I'm going to get the dual 2ohm ssd 15", and I'm gonna have it running at 1000wattsRMS@1ohm off of a Hifonics Txi1008D. Which should I get the flatwind or copper coil? I'll be running 8GA. And the box I'm going for is 3.6cuft after port and displacement. Port is tuned @ 33hz. I have 40 inches of square port. Its 34"W/17.5"H/16"D And just to make sure I did a picture on paint, here ya go. Am I ready to order?

This past weekend I attended DBDrag World Finals at Dayton Ohio (I only live 45 minutes away) and competed in the 3x event. The event was ran great from the judges and ran smooth from start to finish. I was very happy to see fellow Fi competitors. One was Dr. Boom. For those of you that don't know him, he has 6 15" BTLs walled in a Scion xB off of 6 Sundows 3500s. His install was by far the cleanest there, and his car was a show stopper for sure. I got a demo from him, unfortunately my esophagus started to close up so it got hard to breathe, but boy did those BTLs sound great!! A total of 5 light bulb covers fell from the ceiling, 3 from Dr. Boom himself, the other…

which one would hit more

Looking into getting 2 sp4 18s or 2 team 18s....whats the wait time if i ordered either one?

Hi, I have a strange issue that seems to be getting worse. Ill start from when I think it happened. My friend and I built a 4CF box for 2 FI SSD tuned to 30HZ. When we put the box in my cobalt I noticed that the wire terminals were upside down. I didnt care at the time I was just wanted it done for the time being. This was back in 2010. A few weeks later I decided to have my other buddy help me remove the box and put it in the right way.and reposition the subwoofers so that the labels looked the right way. When I was reorienting the subs I unhooked one completly to show my buddy,turns out when I hooked it up I wired the coils out of phase. I didnt know until I was on my w…

Ok i am gettin a 240sx do yall think a fi btl 15 or 18 wood blow out the windows of the car and if so what is a good kinda glass to get to keep that from happen

i have two fully loaded fi btl 18 dual 1 ohm subs cant decide on wich amp/amps 1 rockford fosgate t4000.1 bd 1 sundown audio saz-4500d or two rockford 2500.1 ANY Ideas???

Ok, I have posted several things in the past asking question to help me with my own vehicle setup, now for something a little off the wall. I am getting ready to have to write a thesis and would love to write it on the mathematics behind subwoofers, car audio, etc. As you can tell from my previous posts I don't have to much of an idea of the all-around idea of mathematics. I was wondering if ya'll could point me in the right direction for anything regarding any type of mathematics behind car audio, etc. Again I know this is a odd request, but I researched every major mathematics college and no paper has ever really been written about this from a college student and wo…

Haven't heard from Nick or Scott in awhile, so I am checking up to see if my BTL has been rebuilt yet or not. I understand that yall are busy, but I emailed you twice, and the last thing you said to me about 2 weeks ago in your last email, was that it would be done nearly 2 weeks ago. Just give me an update is all I ask, and please don't take this as me getting hostile or an attitude with you. Any time I have talk to Nick or Scott, they have been very helpful, and I understand that this a busy time for them right now, but I would really like to get my sub back if it is finished. Thanks, Jonathan

I have a saz3500 and i was wondering will that be enough to power to get these bad boys moving?

Went to lunch today and when I got back to the office there are 2 big boxes on the doorstep. I didnt realise anything until I saw the USPS logo on the boxes and I know that is may package. As I carried it onto my desk I realised that the sub nearly fell off. After opening it I saw the packaging was terrible. I'm not sure whether it was originally packed that way or the someone else opened it to have a look as there were signs that the box was already opened. Well I am just grateful that the sub make it without any cosmetics defect though. Anyway thanks Scott for the subs and I cant wait to built a home for it. I'll post pics tommorow. This sub will go into a 3.5 cu. ft. a…

Well to make it easier and shorter let me just paste the link so you can see what the problem is....: http://forum.ecoustics.com/bbs/messages/4/354626.html And since im on this forum now, my other 18" has never been able to go to 1 ohm load. I am hooking it up correctly it just doesnt even turn on when i try to parellel it. What could be the problem?? Thanks, Thomas

Pwnt! , that is all.

i have a fully loaded bl15 and i need an amp, wich amp would be good for my sub???

due to a drunken night i completely ruined my Fi shirt. i poored cranberry juice all over it, and somehow got a hole in it. it was my favorite shirt, and now i need another......is there any way i can purchase another one? feel free to pm me with details, or ill contact by email if need be.

Which is better? what are the good and bad points of each? can one handle more power? does one sound better? whats the deal? lol

Paid on Apr. 18th, still nothing, FTL. Damn USPS. Paypal id #1HR841786S1913713 I shot you an e-mail today as well Nick, not sure if it went through or not.
