I bought a used 18" ssd from a buddy.. I sorta wanted to due a sealed box with it but I was told you need the copper coil option to be able to due a sealed box.. I just didnt know if there was any way to tell. Any help appreciated alot

yes, i searched. my sincere apologies if someone has asked this before. i am planning on buying a single 12" D2 SSD or Q... which one is yet to be decided the amp is a hifonics 1206d, an alleged 1200w rms but closer to 900-1k probably. stock electrical + big three already built the box, ported 2.25cubes@34hz so.... i want to make sure the sub sounds good, i know both of them will get plenty loud for my tastes, but my main question is, if i get the copper coils does that reduce the rms rating of the sub? do the CC's really make taht big of an SQ difference? the reason i'm asking, is becasue the FW coils improve the power handling at the expense of some SQ, so i didnt kn…

Does the 15" BL need to be in a 4cf enclosure to work well or can it be used in the smallest recommended enclosure which is 3cf without sacrificing anything?

Hi im gettting a 12" q and i was wondering if this could be done? I just dont want to worry about tinsel slap and i kind of like the look better thanks

This is my original plan and am wanting to make sure this is my best option for Loud and clean bass. I was used to running 1 Audioque 15" ported at 29hz in 7.5cu ft box off of 1400w, it was ungodly! Current setup - 1 Audioque 15" Sealed in 2.2 cu ft off of 1400w. It is a little less loud in the low frequency area due to a lot lower group delay as well but like how it sounds as well. Anyways, my current project is to have 3 12" Qs off of 3 optidrive 2000ds. Each q would be wired to 0.35ohms all in a common chamber sealed box roughly 2-2.4cu ft stuffed with polyfill (emailed fi about this to see what they say bout the polyfill). Now, these amps are rated at doind 1,600w at…

I am selling my MD2, and I have a 40.1 sitting there for when my 2 other Q15's arrive and get installed. My questin is... If I am careful with the gains, is it ok to run only 2 Q15's on a 40.1(rated @ 3600w rms @ 1ohm)? Or should I just wait until I get the 4 pack installed?

Ok, so I already have a Fi Q that I have been bumpin for about 4 months now. I am planning on getting a second Q after X-mas. Should I recon my broken in one before throwing it in a box with a new woofer? Also, what would be the total price for a recon kit with is being sent to 95677. The sub is a Q 18

Hi, I'm for sure a newbie, especially when making boxes, I just ordered my first Fi product ever, the 18" SSD, and i'm super excited. Probably to excited to be honest but I have a question about my box. I used RE's box calculator and tried to make it fit perfectly in my vehicle, I wanted the box tuned to 30 hz and I did all that. The thing that I'm worried about is if my sub is going to move to easily and I'll end up damaging my woofer D: The box size is 5.6 cubic feet and tuned to ~30.7Hz. The port is 3" wide and 22.5" tall, and its a slot port. The port area is 67.5 square inches I can give all exact dimensions if needed. Thanks in advance!

is a single 4"ID x 5.5"L port enough for an SSD 15 in 3.5cu ft. the box will be tuned to 33. trying to finish up the details on my enclosure and i keep questioning this.

ok so i just bought an 18" fi btl fully loaded dual 1ohm....i originally wanted my box to be 40"x30"x20" with a port size of 10"x18" (which would pretty much take up my whole trunk space) tuned to 35hz ....but ppl tell me thats probably too big...its goin in a lincoln navigator...can anybody PLEASE just tell me if thats ok or too big or what it is that i have to fix to make my sub hit HARD! also how should i face my sub and port? i originally thought both up, but i heard sub facing up and port facing the rear is better, is this true? ok well first off i working with a hifonics 2000 watt brutus for now...hopefully a saz3000d soon...i listen to mostly rap but pretty much e…

ok this is what's up I have an mmats d3500.5 I can buy 2 more or 3 massive p3000.1, already got 3 kenetik 2400's to add to the 2 1800's under the hood. I plan on putting the 3 15's in a fiberglass wall like the old JL audio 3 10 set up approx. 7-8 cuft per sub, so what amps would you guys suggest. Oh getting 3 massive's or 2 more mmats would be about $100 doller dif.

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…

Ok I read the options page and I understand it pretty well. My question is I know I need to get one of the cooling options on the sub but which one? The sub will be used for daily. If I go with cooling, the strength of the motor will be reduced but if I g with just teh p/chamfer option, will it be enough to keep things under control? I really don't want to loose any structural integrity inside the motor if I don't have to. And the inner heat sink? I don't quite understand that one what is it for, and do I need it? So the options that I think I need are: p/chamfer, hi xmax coil, daily, universal? Would these options be what Ineed for daily 2k+ rms? thanks

hello i currently have one 18" bl in my trunk and the box pretty much takes up all of the usable space, i have this box : http://www.subwoofertools.com/forum/ported...mp;Fs=&CE=0 Anyways i was wondering if it's possible to fit a second 18 while still keeping the box dimensions because i can't make it any bigger due to space restrictions..any help is appreciated..thanks

Hello all my box is finished,carpeted ,tuned at 33hz... what is the best tune for my subsonic filter? my ampi is a DD Z1 thanks a lot

hey everybody, ive had my 15" BL for a month now and its running off a Rockford P1000-1BD (1328 rms @ 1ohm) but ive noticed after playing a couple of songs its hot to the touch but not too hot,,my gains are only half way and the bass knob is only half way.... i was wondering if this is normal and is my sub taking on any damage by being hot....????

I have 2 12" Fi SSD's with copper coils coming soon and I need a box for my Charger and found this. http://cgi.ebay.com/2006-Dodge-CHARGER-SUB...%3A1%7C294%3A50 Would this box be ok to use or should I have a shop make one? I also found a ported one http://www.onlinecarstereo.com/CarAudio/Pr...ProductID=21319 I mostly listen to rap but also listen to rock, death metal, etc. if that helps

Robin (iamamp3pimp) was in the process of building me a 2.8^3 @ 35Hz box for my AA Chaos 15D2 when I had to sell the sub due to financial issues. My question is would a Fi BL15D2 run off my AP15001D work in this enclosure? Sub would have cooling, flatwind, and daily options. Looking to get decent lows and numbers out of this box, though sound is more important than numbers to me. Had the CHaos 15 in a similar box before with good results, just bumped up tuning on this new box from 30 to 35Hz trying to get a little better score than the 143.7 at 40Hz I got with the first box. Here is a pic of the first box, new box will be designed the same but built out of raw birch. Th…

I have a 2006 Nissan Sentra (1.8L) that has the stock alternator putting out 80 amps. I am looking to soon be running 1200 watts RMS through the system. I know I will have to do SOMETHING with the electrical system. But what? New alternator? Extra battery? (Big three is a given) If new alternator, would the one in the link below be suffice? (20 extra amps) http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=120530973171&viewitem=&_trkparms=algo%3DLVI%26its%3DI%26otn%3D2&category=33573

Been debatin on 3 10" bls or 1 15" BTL off of 4Kw. I'm thinkin about goin with 1 15" BTL so i got some questions. What options do i need exactly for the following scenario? - It's for daily, tuned to 33hz, running off of 4kw of power. No SPL but i will be playing, sometimes, bass tracks for show off purposes. Absolutely no clipping guaranteed. Let me know if this is correct or if i should change\add something- Cooling, HIXMcoil, 3rd mag(do i need?), Daily. Can the BTL take 4KW daily? I know Meade does it but is it still safe in Fi's eyes? And i would like a discussion on the cooling option. It states not to get it if used for SPL. Can someone please define what specifi…

ok guys im gettin a box for 2 BTL's fully loaded...anyone have any ideas bout where to tune it to and how big of a box??? thanks
