Good to go? More stats: http://www.subwoofertools.com/forum/ported...mp;Fs=&CE=0 Anything else to change? I'm gonna buy the MDF this weekend.

Hey i use to have 2 (dual 2)12" kicker cvrs running off of a zx750.1 now i have 2 (dual 2)12" FI ssds running of a zx1500.1 and my cvrs are louder then my ssds, the ssds are in a 4 cube ported box tuned to 32hz. My electrical is a 200a EA alt, Yellowtop under the hood. Ive got 10guage speaker wire, 1/0 power/ground wire. When i try to set the gains using the gain setting tutorial i dont get any voltage reading from my dmm so i try and set it by ear and the subs just stop playing when the subs arent moving that much. Im not sure whats going on. Im almost positive i hooked the subs up to read a 2ohm load i remember goin gfrom the positive from amp to positive to sub to posi…

If I have a traditional trunk (large 300c trunk) and I fire the sub towards the back but fire the port up on the passenger side of the car, does the direction of the port make any difference, up, back side? I assume it would a little if there was resistance from say a seatback or side trim but up into the rear window or towards the empty trunk in the back, will there be much of a difference in the cabin as far as sound etc... Just got my 15 BL today ($105 extra for DELIVERY WTF?!) and can't wait to get it in... I am going to tune it to 33 or 34 hz PS: How reliable is the ported box calculator at reaudio?

Well, my box for my truck is gonna have to have a few pretty tricky shapes in it and I need to be sure that the magnet will clear on one side thats gonna be sloped.... I just need to know how wide the mag is on the ssd and if you don't mind, the Q as well... Thanks...

I have a BL 10" with DVC 2 ohm coils, I am wondering how hard it is to install the recone kit FI sells to recone it to DVC 1 ohm coils. I am asking because I am now considering ordering another BL 10", but I would need a DVC 1 ohm to get my amp down to 1 ohm . I know there are some out there that have ordered the kits from Fi, so guys, how hard was it for YOU to recone your sub with the kit??

hi im waiting for my FI SSD12D2 and i have a soundstream XTA880.2 and im gonna bridge it to run a 800rms 4ohm load to the sub in a 2.4cuft slot port box i have a 4g wire from my alt to my stock batt and a 4g ground from neg post to strut tower and a 3 farad spl cap can anyone plz give me sum tips to maximize my setup...i have a stock 90amp alt also also i have the flat coil option on the FI SSD12D2. the amp will b @ 4ohm so it will b a clean 800 rms if im right ? any info will help so i can make any changes b4 it gets here

3 weeks and no replys to email. i would realy like to get the kit. thx

My sub sounds like ass in the box that I currently have it in. Waaaay too much port noise! I am only running a single sub right now, but I will have two Q's pretty soon. I am in desperate need of a box design to fit my needs, my parameters are as follows: (Max Dimensions Given) Depth - 15" Height - 16" Width - 34" I need the box tuned to about 32HZ. I would like to keep the chambers separate, as it might be a while before I buy the other sub. I would like to hear what the first sub sounds like before spending more money on another 1. All help would be appreciated. You can PM me on caraudio.com under Qbenjamin.

ok so i was thinking of either getting 1 or 2 fi q 12's or 1 or 2 fi q 15's because i want a little more sq, but i like listening to rap sometimes and i was wondering how low a q 12 can play

sorry to make another thread about it, but i can t get anybody to answer me about my mt motor i sent to have repaired..its been over a month! i got a email from scott about it being fixed , then i never heard a thing ...i have emailed fi , and scott many times and no replies......am i ever going to get my motor back????????? or am i going to just never get it back......???? i was going to buy 2 btl 18's from you after i got my mt motor back, but if this kind of customer service is what i have to look forward to , im not going to buy a thing ........please let me know something please...

I have a excursion w/2 -18 Q's and want to know if i can tune them to 30hz instead of 28hz? and should i have the port and subs firing to the rear or facing up? all my boxes always had the port and sub on the same side.I would face them to the rear. I would face my box up and the bass cuts in half. Will this do same if i face the subs up and the port to the rear? I want to get the most that i can get out of subs and box. Any input....

I recently bought a 15' Bl and had a enclosure in mind. The enclosures dimensions would fit inside my car, so I went ahead and bought the 15' Bl with the cooling option. It arrived a few days ago and I was super siked. Then I realized how would I get this box into my 99' Grand Am GT. The box will not fit. (This one http://www.bestbuy.com/site/olspage.jsp?sk...=1218009774927). Now I'm in a pickle. I have found another box that is ported,that i think will fit in my car. It is on the small side as far as cubic feet wise though. link to it --->http://www.bestbuy.com/site/olspage.jsp?skuId=9026797&st=15+in&lp=4&type=product&cp=1&id=1218009790168 Will th…

The motors on these woofers look almost identical. I know both woofers are made out of the same build house. Is there any difference in the motors? I know Xcon is more of a sound quality woofer, Im a owner, and the BTL is more of a SPL woofer. Is it the soft parts and the coil that make them sound different? Please excuse my ignorance on the subject.

i already got the amp, would 1 saz1500d be enough for 2 BL 18s until i can sell the 1500d to get a 3000d?

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…

My friend is buyin a Fi Q with all the extras and we were wandering if any body had any old box dimensions and i dont want the dimensions from the website Q 15 – We recommend using a sealed box in the neighborhood of 2-2.6 cubic feet of volume. Ported box we recommend using 2.8-4 cubic feet @ 28-33Hz. Again use 12-16 square inches of vent area per cubic foot of volume. so plz if u have some dimensions for an 15" Fi Q ported box Thanks

Hey guys i have 2 Btl's fully loaded each runnin off a zx2500.1. Each sub is dual 1 ohm and im looking to throw another 2500.1 on each. What possibilities do i have as far as ohm loads ill be seeing.

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

Hello all, I purchased a Q12 years ago and unfortunately for the life of me cannot remember if it is the dual 2 ohm or dual 1 ohm. There doesn't seem to be any markings on the sub or coils...how can I tell what I have? I could have sworn it was the dual 2, so I wired it in parallel to put a 1 ohm load on my amp. It sounds great, but the amp is going in protection mode when I turn it up. The amp is 1 ohm stable. So I pulled the sub out, wired it in series...which would put it at a 2 ohm load (if it was in fact a dual 1). No matter how much I turn it up, it stays on just fine. Problem fixed, right? Wrong. The sub sounds like crap now! As if the polarity is wrong or somethin…

Hey guys I'm looking for blue prints for either a single or dual 15 inch ssd ported box with optimum area space. I'm not new to stereos or box building, I'm just way to lazy to design my own box. So I was wondering if there are any blue print boxes laying around like element designs puts out on there site. Thanks in advance and hopefully you guys have some so I can get to building.

ok here is my question can i run 2 amps (mtx tc4001) on a Fi q 12? the amps are rms 600x1 at 2 ohms. i know that the FI's are dual 2 ohm. right now i dont have the cash to buy the amp i want(sundown). the other mtx amp should be here soon but until then can i only run one VC? is that safe? any answers would be nice? my friend has one of the FI Q 12 in his 06 Z71 and man it sounds great... i want that sound

hey guys... i am trying to find out the T/S Parameters of the Copper Coil Option. i was looking at the Fi site and thought it was weird that the BL rating was so low when compared to so many other drivers. would a very low BL rating not be ideal for Porting? i was considering doing a PR or Porting the box, but i was told by the guys at AE Speakers that a low BL # leads him to believe that it is not a good candidate for porting or a PR. does anyone have decent experience in porting the copper coil SSD and what results have you had?

My sub is less than a year old. Listening to it while driving on the highway one day at about 1/3 the volume and it just shut off. I thought it was the amp or a bad connection somewhere. How do I get this fixed? Is it covered under warranty? I have an Fi Q 12

assuming both are in 8^3 ft @ 32 hz with 3kw to split between them @ 2 ohms with equal installs. which ones would be louder? my main concern is, do these subwoofers basically take power the same way and just 1 gears it more towards an SQ aspect and the other a SPL aspect. or is basically just the power applied that will determine which is louder? i mean both are rated @ 1kw and the only thing that seperates them are the power options that apply to the thermal side of power handling. but mechanically, as far as power handling goes, are they the same? same stiffness spiders etc? i have been told by one guy that his 2 15" q's were louder off 1.2kw of power than his bl 15's t…

Just a quick question, I have a JL 12W6V2 that I bought on ebay a couple of years ago. Sub worked fine for a while, but eventully died on me (my fault of course, got a lil greedy with the gains lol)and has been collecting dust at the house ever since. I was wondering if FI can do a recone on this sub? Thanks.
