Fi Technical

Hi. I just purchased two 15" Fi BL's and im looking for a ported box that would meet the desired dimensions for the subs. Can anyone help me out and point me in the direction of a box i can buy. Thanks

So i picked up my 18 inch btl with hiXM coil and cooling options(DAILY). Now for the amp. Normally i would say that i don't have the money for the SAZ-3000D, but i found it online refurbished for the same price that i can pick up the Rockford Fosgate t2001BD from sonicelectronix. I read a post from a guy who got the refurbished SAZ-3000D and he claimed that it was functionally perfect so i wouldn't mind purchasing it. both are about $560. I plan on doing all the elcetrical upgrades necessary for either of these amps (big 3, Kinetic hc2000, high output amp, all that good stuff) now my only concern is that my sub is the dual 2 ohm and i will be running it down to 1 ohm like…

I have a toyota ex cab truck and I was wanting to know what is the biggest sub set up I can fit in the back? The space in the back is 19'' deep X 22'' tall X and 53'' wide. I want to do a ported box with either 2 Q18's or 2 Q15's. Given this amount of space what do you think I could fit back there? -Alex

Hi everyone on SSA and Fi audio, i am new to this forum. I herd lots of good things about Fi audio, so iv decided to give there woofer a try. i plan on ordering one in a few weeks. im thinking im gonna get me a single 15" BL to start Fully loaded as a daily with 2ohm and universal option. Now my question is i need plans for an enclosure and also what should it be tuned to?..... I never tuned a box myself so i may need some step by step if its a complicated design. Thanks

I'm running an SSD10 in a ~.8cuft sealed box with 400W from a PDX. I'm mostly satisfied but it seems to lack the very bottom end...just doesn't have any oomph and sounds like response rolls of pretty sharp. I only notice it once in a while on certain tracks where I expect to get a low hit. I've had this sub for a couple of years but I swear the enclosure specs used to call for a larger enclosure compared to the .2-.6 I see now. That's why I'm in the bigger box. Can this thing really perform well in .3-.4cuft?

2009 corolla, trunk i 13cubic foot.

So if I get a DVC 2ohm BTL that means there are two voice coils, which just ONE can handle 2kwrms correct? So if I hook up 2kwrms to each, shouldnt that work? Or lets say 1500 on each coil for less heat? Yes yes I understand Im retarded, but you never learn if you never ask P.s. figured out my other question..

So I'm new to car stereo and was hoping yall could help me out. I've been doing alot of research on subs and have decided on a 15" BL for my tahoe. Im wondering if yall could help me make some decisions on which options to chose for the sub itself and what kind of amp i would need to power it. I'm looking for some pretty hard hitting bass at some points, and at others i just like some good sounds. Thank yall for looking and for your opinion.

I need to know what kind of re cone i can get for this blown RE Audio HC Quad Coil or if i can even get one.. i would like to make it a dual 2 or something wondering what series you think it would stand up to with the FI's i mean this HC is tripple stacked magnet but i dont think its a BTL... i could be wrong thou. Let me know thanks Jesse..

What would be an excellent recone epoxy that I can get from Lowe's or Home Depot that would be good to reconing 3-12" FI SSD's???

I have 1.0 cubic feet before displacement and it is a sealed box. I am wondering will I be able to get a 12" in there with adding polyfill and make it sound good or should I stick with the 10". I will have a sundown sae1000d powering either one.

Can anyone design me a box for 2 12'' fi btls? I have a blazer i would like it tuned around 30 hz any suggestions?

Will the new sundown sae 1200 coming out in november be too much for a 15Q loaded?

i need help choosing between these two designs for my 12" BL. my last box didnt turn out so well. so i was hoping you guys can maybe help me out a bit. amp:hifonics bxi 1606d goal:spl first design: H:14.25" L:30.5" W:18.25" port width: 3" total port length: 29.75 square port area: 38.25 box volume:2.9 cu ft (before double baffle) tuned to:34hz second design: H:14.5" L:30.5" W:14.25" port width:2.5" total port length:31" square port area:32.5" box volume:2.18 cu ft (before double baffle) tuned to 36hz any input is appreciated, thanks.

Scott suggested that I do a 0.47 cu ft box. I'm having trouble finding the right dimensions. Can anyone help?

Ok if I build a box that has a port that 'folds' would that be just as good as a regualr port?

i am looking to try out a new design in my ranger. this will be for a 15" btl fully loaded. my max outer dimensions are 50 long x 16 deep x 18t all. heres the kicker, i would like the sub in the middle of the box facing the roof and would like to have the ports doing the same on each side of the sub. i am looking to get it tuned to 30-35 hz. the only reason i want the sub in the middle is because my truck is bagged and i want the weight in the center for even psi on both sides. i live near milwaukee wi if anyone is wondering

I was wondering if anyone know the spec sheet to this enclosure at 2.5ft^3 32hz. 3-D diagrams don't hurt =D

Is it that hard? How long would it usually take?

I am debating if I should dampen the custom box when I get my 12 fi bl 2ohm. Also what do you guys think about powering it with a PDX 1.1000 at 4ohm ~1229 rms?

I just got 2 more 15 fi btl to put in a 91 blazer. The box I am going to build will be 38" wide 31" deep and 20" tall. I want both subs facing straight up with the port also straight up. I was wondering how big I should make my port. I am looking to get around the 32 hz mark. Also I will be bracing with 1 1/4 inch wood dowels and will be using 3/4 inch mdf.

Need to know how much a recone would be for this sub. Thanks

Im gonna get 2 12in BTLs and I was wondering if they could handle 3,000RMS or higher and not have to worry about it, and the sub would be a daily sub but fully loaded otherwise.

OK, i am doing a system for a friend in a 1996 lincoln town car, the equipment i am getting is 2- 18" SSD's and will be powered off a Rockford Fosgate t1500-1bd . The problem is there are hydraulics in the car so i have very limited trunk space to work with. the measurements i have taken leave me with a max of 39" wide x 24.5"length x 14.5" tall . i think this comes out to be about 6.6 cu.ft. BEFORE any displacements . I know that this is WAY UNDER THE RECOMMENDATION, but i do not have any more room to spare. it will never be metered or compete it is just for show which is why he wants the 18's but even though it's, not going to compete it still has to be LOUD. I was…

Looking at Possibly Doing 2 18" SSD's in the Trunk of a Lincoln Town Car (1996)..On a Massive p1500.1,,, I was just wondering on overall efficiency on the ssd's.. ive yet to play around much with 18's and i figured i could fit a good 12+ cu ft back there.. Im thinking possibly subs up vent back but was wondering everyones input on overall sub/port placement on that specific vehicle
