At 1:03 ish. Is Steve just not pulling enough power?

hey i was wondering how much will it cost to recone a re mt 15

Would FI Recone parts work to recone an older (3-4 years old) XXX 15? possibility of getting 2 blown ones for basically free. Thanks !

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…

so i only ask this because i saw this and i have all ways been told to run both coils at all times. but they are saying using one of the two coils just means you can just run half the power to the sub and its no harm no foul. they also said that you can use the second coil with a potentiomoter for a variable QTS system. i would like your thoughts on this, and i thank you for taking time out of your day to answer me.

Hi Fi...I have (2)Audiomobile Mass series motor structures. no frames or top parts, just the magnet strutures. They are(were) 3inch underhung dvcs. Can they be rebuilt at all? They don't have to be dvcs. I would actually prefer single 4 or single 3. They need whole new top assemblies and softparts. Can this be done...ballpark cost for 15's. Thanks for any info.

I am in pretty desperate need of help...I tried to design a box and I keep getting lost. I am working with about 18" in height, 48" in width, and roughly 20-25" of depth. I would like to do 2 15" BLs tuned to around 34 Hz or so. Can someone please help me out. Thanks.

hey i was just wondering if i could get a quote for; replacing a broken magnet slug, and a recone plus shipping both ways on a 05 xxx. shipping weight would be around 65lbs and its shipping from 87401 thanks again guys!

I must say Nick is the man. I contacted him with a few questions about my order December 12th and not only did he adjust the order my 3 SP4 15's arrived 14 days(not working days) but 14 days later. That's only 7 working days because I am sure they took Christmas off. That's fast customer service and the reason why I stick with this company. Just wanted to thank Nick again. This will be my first time running 15's.

I have a Blueprint 1503 from several years back. Someone told me that Fi's owners used to build these, and may be able to do a recone. Any info on this? Thanks.

My friend has two Alpine Type R's. After hearing me mention the fact that Fi makes recone kits for a coupla companies, he asked me to find out if you guys could recone his Type R's. -Thanks -Chris

Okay I am planning on getting a new substage setup in the summer because right now im just a poor college student lol. Anyways I have had a fi btl 12 before and loved it but now I know I want an 18 for sure and I have contacted argent audio and an 18 will fit with aero ports so my question is should I get another btl or the Q. I loved my old btl but honestly sometimes it was just to loud and I have heard great things about tthe Q. I have never heard a sound quility sub in car auido before though. I like it loud but it doesn't necasarly have to rattle everything too. So I was just wondering what you guys think between the two wich would be better. If I left any iformation …

I am looking at setting up a sub in my car. I have had systems in the past, but I'm used to just running subs from Crutchfield or Best Buy - just choose your size, amount of coils, and throw it in the car. I am looking for a single sub that can handle a lot of power, but still be very clean. I'm not looking to go to any shows or SPL competitions, I just want to enjoy it in my daily driver. My problem is I'm ignorant on reading the specs for the subs on Fi's product page - I don't know what they mean by Fs, Re, Qms, Qes, etc. I have an Elemental Designs Nine.1 amp that I am going to use. It is rated 1200W x 1 @ 1 Ohm and 900W x 1 @ 2 Ohm. What sub would best fit my needs -…

Initial impression is WOW! Haven't built my custom box yet but had an extra one that's 1.4cu ft so just plopped it in. Didn't change any settings on my amp but man, it sounds like there's 2 12s in there. NICE! Just did a search, looked up a few suggestions on what to set my amp at and will bump it when I go to school later. Thanks all for the help and will post pics later this weekend (papers and finals coming up). -Sunny

So i just recently bought 2 15in BL Dual 2 subs with the cooling package and i have 2 questions... 1) Now im usually pretty good with this buuuuuuut I'm guessing that Dual 2 means that i can only wire the subs at either 2 ohms or 4 ohms... 2) If I can only wire it down to 2 ohms what amp should i use? ive been looking and looking and the only amp that i could really find to push em was the Power Acoustiks 5500 BAMF series amp that puts out 2500w rms at 2ohms Any answers/ suggestions would be nice... THANKS

Hey Scott Just checked out your pics of the shirts that will be available. A little pricey, but considering all the stitching and how great it looks...all worth it. I am a little new to FI, haven't even gotten my subs yet, but I can't wait to rep you guys and get that shirt.

Just wanted to post again now that it is 2 weeks away. If so, are you competing or just banging out the trunk? I'll be going saturday and hope to have my btl in by then

as stated, I'm between these two subs. the r is rated @ 750 rms, and the bl is 1000 rms + whatever the flatwind coil and cooling adds. I'd love to get the bl15 cause I hear it absolutely pounds, but I'm scared my amp wont do it justice. Whats my best option? im open to any brand/size of subs too, looking to spend up to $275-300 thanks

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?

We're going to start doing some fun stuff with the Fi Side Chat and on our Facebook page...add us and we'll update the page and get some stuff rolling. http://www.facebook.com/home.php?#!/pages/Fi-Car-Audio/163751923651416

I had my 12" dual 1 ohm Q reconed right before i sold my old car, and have decided against putting a system in my new car as i have a baby due in 8 weeks and need the trunk space. so it hasn't been used at all since the recone. what do u guys think i should sell it for? thanks anthony

Whats up everyone i just received my 2 US amps (md-3d) 2000rms @ 1 ohm i am goin to be running 1 amp per sub 18" fi btl fully loaded just waiting for the subs to get in so i can build my box...cant wait to see these monster subs hopefully they are shipping out soon...........

What would be the best choice for an amp that could power 2 15" FI btl safely at?

All week I have been sitting around like a kid on Christmas eve and finally she arrived yesterday. I dropped her in and added a run of 2/0 welding wire as a ground for better voltage. I am soon to be adding a HO alt and finishing my big 3 off with better wire. Anywho all I can say is wowwwwwwwwwwwwwwwwwwww this sub is loud as hell. First setup I had that really hurts my ears. Like really hurts them and the thing that I like the most I still have more left in it as far as tuning it. I would like to say that to the ear thus far this setup is far louder than my 2 12" ssds on the same power. Only thing different is I actually built the box for my 15" as opposed with the 12"s …

Yesterday i received the amp wiring kit and the 10ft of power cable for the "Big 3". Today i received the 25 ft of speaker wire and the headunit. The sub and amp should be coming in shortly and then ill be installing it... so now i gotta decide quickly on my box ideas. I have decided to get a sealed box... i guess about 2.6 cu.ft. there is only one thing left to decide --- which way the sub faces and where to put the amp... in terms of sub direction/placement, i was thinking of doing something like like having the box in the trunk and when i open that armrest thing the sub will be facing towards the cabin....i was thinkn like when u opened the trunk itd be like sealed …
