General Fi

So, I am lookin for an amp to run 2 10" bls and am not entirely sure what to go with, would something like a RF4000.1 be good or should I stay with a 3k watt amp....in which case, what is a good 3k watt amp

I have a 12'' fi q with the bp option in a downfiring box 2.5 cu ft tuned to 32 hz. I have a hifonics bxi 1208d powering it. I am worried that i am clipping the signal. I had the radio turned up to 25 ( goes up to 62) and everything sounded good and crisp but when i turn it up to 50, it seems like the bass isnt as loud and not as crisp. Idk if i have things set right. Here are the places i have things set two: Subsonic: Three o'clock LPF: 1 o'clock Gain: 12 o clock Bass Eq: 12 o clock I know hifonic amps are known for clipping and are pretty cheap. I just need some advice on what this is. I dont wanna fry my baby.

Ordered a 12" Fi Q dual 2 tonight Will be purchasing a sundown sae-1000d later in september to go along with it

Sup guys Given i have limited space in my ride i was wondering which of these boxes would be loudest: ported 5.3cuft after displacements @ 31hz or sealed 6.88cuft after sub displacement I could tear out the backseats which would give me plenty room to make huge boxes (16cuft) but im not really eager to do so. But i will if there's no real option. Im also just wondering if this will be louder/lower than my previous setup : 2 12" RF Punch HX2's ~ 4.3cuft @ 33hz PS. This is on a 1000wrms

question in title. wondering if there is any way to VISUALLY tell if a BTL has the daily versus the spl option. got a sub im looking to buy...but the dude doesnt know if the sub is daily or spl (he bought it from a guy named "beau" who goes by the name "astrolade" on caraudio.com) and i have no way of getting in contact with him.

I ordered the 18" BTL on december 30th. I've been reading that they don't get like the motors in or some stuff till next monday? Thats fine with me, cuz I got a lotta work to do on my car. I have 3 batteries, one to replace under the hood. No alternator yet, but I'm doing the big three. Sub up, port back no speaker upgrades yet and headunit soon, but probably after an alternator does that sound decent for now? I'm going to start taking out my third row, and I'm paying 10$ for box specs from a kid named aznboi on an explorerforum.

would a alpine m1000 be a good amp for a fi bl 12? i was going to get the SAZ-1000D but i can get the m1000 for cheaper. there both 1000 rms so i think it would be good

A while back I posted a topic about one of my subs having a softer suspension than the other and I knew this would happen because one was bought like several weeks before the other but figured eventually they both should level out to have the same stiffness of suspension but that isn't the case. After doing some testing last night a couple of buddies of mines who happens to be a serious competitors bought it to my attention and said it may cause somethings such as cancellation or something then again it may be nothing but you never know. Again I have bought this up to FI and said it would be fine and eventually level out but I am worried that one of the subs may have a be…

so i have been tracking my shippment and it finaly got over the border and into windsor. but all of a sudden it is back in the states no in ilinios? what does this mean and am i going to have to pay more dutie on top of this?

When it says that all subwoofers are custom made in 3-7 days. Is that one subwoofer or is that the ones you order. Like if i ordered 2 12". and it took 3 days to make them. would that mean 3 days to make each sub. or 3 days b4 both were sent

Big Island guy, on O'ahu for school. Was looking at RE's SXs, but now I'm really leaning heavily toward Fi's BL 12" after reading online. 1. Can you quote me shipping cost (USPS if its cheapest without being super slow) to 96816 2. If this is non-competition, wanting a solid daily-driver that can handle my old Kicker 1200.1 which if any of the additonal options should I be looking at (i.e. cooling, flatwind, etc.) Thanks for any info, I've been building my own systems for about 8 years but haven't had the pleasure (or so I hear) of working with Fi products yet.

I'm a noob so bear with me. I would like to have some trunk space available after i put my box in. Interested in a ported box I really want the 15BL but i am afraid it'll take up to much trunk space but i can settle for a 12BL if i need too. If i choose to go with 12BL or the 15BL, what dimensions and tunning spec so i go with? I listen to old school rap, trance and a little bit of alternative rock. Also which voice coil option should i choose to go alone with my amp? Current amp is autotek SS 1900 Thanks all

Just picked up one my BTL motors, plan on getting another soon. And I am working on a new box as well. I will be giving a Sundown3000 to each BTL, my question is can I safely tune the box low? I wanted to tune around 29-30hz but I have been told tuning that low with that much power on them is not a good idea.

if I got a tracking number does that mean my woofer shipped out?

Can a BL 15 handle 1000 watts rms on music for 10 to 15 min at a time with just p chamfer, Daily?? I need to know asap so I can place my order. In a 3ft3 enclosure tuned to 48hz.

Could you guys @ Fi recone a Poweramper XP2 18" if your not familiar with that it's identical in everyway to a old school Juggernaut. Please any help would be greatly appericated. It has a 3" VC but I'm not sure about the diameter of the spiders.

Need to place a order but I refuse to use paypal, please pm me a phone number so I can give you my order and credit card info.

Wondering when you guys expect the BTL backorder to be filled and shipped? Maybe its already done I don't know ha just seeing what the overheads looking like. Thanks

hey, ive been trying to contact you guys about recones for my 2 8" assassins that i sent in a while ago. ive been emailing scott back and forth, but my last email was last week, and he told me he'd call me on monday for my card info. its now friday, and i still havent heard anything from fi. i tried calling today and left a message, but no reply...any updates for me? im desperately waiting for my two cute drivers to show up.

Not sure if this is the right place for this, i apologize if it gets moved. So my concern is if sub-zero temperatures have any effect on subwoofers or their electrical counterparts. I know it seems stupid but i want to make sure i don't harm anything. I'll be attending michigan technological university in the upper peninsula of michigan next year where its not un-common for temperatures to reach below zero in the winter. IS there anyway that prolonged exposure to those sort of temperatures could hurt my btl? or my sundown amp? thanks

Hi there guys, I was wondering if someone could help me out. I've placed my order a little over a week ago and Paypal is still processing my payment. I wanted to change my dustcap to the Brushed alluminum instead of the white. My order number is I-17454/00.

Hey I'm new to this forum but I was considering getting Btl's as my next sub but I got a few questions. I already emailed nick but I thought there might be some members on here that would have enough experience with BTL's that they might be able to help me out. I want to get 2 12" Btl's and was wondering if they could handle 2500 to 3300 watts rms on a daily basis? Im going to have a Kicker 2500 at 1 ohm to each of them. I'm going to be competing with them every once in awhile to but I'll be listening to them on a daily basis more so that comes first. I thought about getting the inner heat sink option and the cooling package. Would this help them handle the extra power on…

This is my rx300 with a 18" btl with a kx2500. 5QLfYZpGA54 Dud9Wqh05lw&feature=related x1xmwCIC88g

Just got my Fi SSD 15" and built my box. The box is 4.3 cubic ft. tuned to 42hz. i know thats a little high but it sounds pretty good. What do you think? I'll be doing a blow-through in my 83 S-10 soon and this will go in it. Heres a video of the build. and heres some pictures

I have a 99 navigator that I just got and am getting ready to put a system in. I am strongly considering the FI BTL 18" sub and would like to get a fosgate t40001bd amp. However, the price increased from last time i looked so the t20001bd is probably in my price range moreso then the t40001bd. I will be getting the sub fully loaded and am fairly unexperienced with high quality subs and amps. My first question is how does a single 18 sound and should I go with dual 1 ohm or dual 2 ohm coils. Will the t20001bd (2000 watts rms @ 1 ohm) be enough to power this sub and make it hit the way it should, or should i go with a different brand of amp ($700 budget)? Finally, would I n…
