Fi Technical

I read the recommendations for each speaker, but still have a few questions. First, I'm going to be ordering a dual 2ohm fully loaded 15BTL, Its going to be for daily with roughly 2500rms to it. My question is, is going fully loaded the right choice? Or will some of the options hurt the power handling instead of help it? For instance the universal option because of the gap size? thanks for the help

I need some 2 cents on my new setup which will be 2 Fi Bl 12's fully loaded. im going to have 2 1700 rms watt amps total 3400rms. i have a 125 amp alternater and a redtop battery. i was wanting to keep my stock alternater for low funds reasons. for now what can i use to power the subs? could more batterys work for now?

i know this will sound stupid but what is a dustcap? is it the cirlce on the center of the sub? the one with the fi sign?

i am about to buy the aq2200d amp, and i am still wondering what subs i should get... 2 18in. bl's or 2 18in. q's. i know the q is for sq mainly and the bl is more for spl. i want what ever one will perform better on that amp. thanks

Ok i have a 03 silverado extended cab and im wanting to put either 2 12 q, or 2 ssd under the rear seat in a sealed box that has .82 airspace for each chamber and a 7 in mounting depth. i dont know what subs would be best because i really want something that would make people stare lol any advise would be greatly appreciated

The recommended box volume for a sealed enclosure is 4-8 cubic feet. Is there much of a difference in sound quality from 4-8? What exactly would be the benefits and disadvantages of having the volume be 4 cubic feet to 8? What about 5 6 7? So far what I could gather is there would be less low-end with the smaller box volume but the bass would be more detailed. Is this necessarily true? I have trued modeling the a box with WinISD but it didn't seem very useful to me. Also, would adding polyester fiberfill be useful in a larger volume box? Thanks!

I haven't built it yet I am just exploring options and found a design I kind of like. 8 cu. ft. tuned to 34 hz with 101.25 square inches of port. The port opening will be 4.5 " wide and 21.5" long. The box dimensions are 33x24x27.5 overall. It will be a crx style box , and will go inside of the cab of a 2000 chevy silverado. I plan on pointing the port towards the driver's side and have the sub behind the passengers seat. Do these specs seem alright to everyone? Would a different direction with the ports yield better results? Does that tuning seem alright or should I go lower/ higher? I want SPL but also enjoy the low notes that a highly tuned box sometimes lack. If any…

The fi Q 15 has a sealed enclosure range from 2.0 to 2.6 cu.ft. At which enclosure size within this range would product the best results for a SQ setup? Thanks guys.

What is the Xmax with this option? I only see the 28mm on their website and I assume this is without this option.

Can it be sealed and sound just as good ported?

okay first off i ordered a 18"bl dual 1,spl,and whatever the site says to order for spl...well i wasnt thinking,i admit i didnt know what i was doing i just ordered it..so i have it installed in my 01 jeep grand cherokee and after a couple enclosures i finally got one that sounds decent...and i have been running it daily with music with no problems..i know im a dumbass but whats done is done..no problems so far..well problem is on the dual 1 side..figured i could recone back to dual 2 since i had universal option but i dont wanna go through the hassle..my amp is the hifonics brutus 2010d..1300 at 2 ohms and 2200 at 1 ohm..since im running in series right now im not really…

What can i do to stop the screws from coming out the box holding the sub in

I'm looking at a BTL15, because I've heard good things. But until I get enough, I would probably be running 1 Sundown 1500d on the BTL15. If I got it optioned out, would it be able to handle a pair of strapped 1500d's? How much can a optioned daily driver BTL handle?

My enclosure is built at 2.5 cuft, my current port area is 10x4x21, tuned to 39 hz, I want to change this so its tuned to 32 and I would need to add 14 in in length, unfortunatly not possible. So I looked into it and I could change my port to 10x3x25, what will I lose(or gain) by changing the port area ?

I was going to order these options: D1 Cooling Flatwind Daily Do I need Extreme lead? My setup will be 2 18" FI BL connected to Sundown 3000D. This will be my daily setup. Thanks,

Scott at fi car audioi sent me this enclosure.. http://yfrog.com/eq23cuft33hzj Is this a good enclosure? Is it going to be very loud and clear?

I just ordered my dual 2-ohm Fi Q15 last night and will be ordering the Cadence iA7 today. I was hoping that one of you would be able to point me in a good direction as to where I should buy an enclosure for this, or where I could have one built. I plan on going sealed, is there an ideal size besides just 2-2.6 cubes? Any other suggestions? Thanks guys

I Emailed Fi about a month ago about the reconed and i haven't heard anything about it. If u could let me no what is up

the topic asks it all.

i am planning on hooking a fi bl 12 up to my kicker zx 1000.1 amp which is 2ohm stable. do i buy a dual 1 ohm sub or a dual 2ohm? please help! thanks

I am looking to run 4 12" BL subs in my SUV and was wondering what would be the best tuning and internal volume for an enclosure that size? Also would it be better with subs up and ports firing back? I will be running 2 Rockford Fosgate 2500-1bdcp amps on this set up.

Hi, I am thinking of getting an SSD motor used and reconing it. I was wanting to know if they are a universal motor and could put either a d2 or d1 recone on it, or am I stuck with what ever impedance that came on the ssd when it was 1st made. thanks

I was planing to make a box for my BL 15... but i have a few ideas.. whats the diffrents from the sub facing toward the rear of the vehical? Vs. The sub faced up ward toward the trunk lid? and what is a good tuneing for the sub? 35hz? 32hz? or 30hz? i have a 1500 rms amp... and i listen to rap and metal.. rap most of the time...

Hi I need some questions answered on the x12. I need some input on what size and kind of box to put it in. I have a phoenix gold xenon 400.1 to power it and I listen to a lot of bass heavy music ( rap, chopped & screwed, etc.). I know what the website recommends but I would appreciate any input or suggestions. It will be going in a 1995 neon 2dr. Thanks!

Hello all, I have a 1999 GMC Yukon that I use on weekends to travel to sporting clays shoots. This truck will never be used in a Audio competition just two semi deaf old guys(36 an 38) like to play it loud.

I have a second Kenwood 9104d (900 watt rms at 2ohm limited to 900watt at 1ohm from what little research I have done these amps really do around 700 wa…
