General Fi

hi im going to be buying 2 of these beasts for my 79 gmc stepside. there going in the bed & ported of course because there is no way in hell there going to fit in the cab. im looking around for amps to power these subs and am wondering what rms @ what ohm to get. i need to know what ohms to purchase the 2 subs dual 1 or dual 2 and what kind of amp. i was thinking about audioque 2200d because fi says the 18's rms is 2000 watts. would two of these amps do the trick or should i look for something else? thanks

i have a fully loaded bl15 and i need an amp, wich amp would be good for my sub???

Which would be best? A US Amps XT2000D (1200 rms), US Amps XT4000D (1500 Rms), Hifonics BXI-1600d (1600 rms, but probably closer to 1200), Power Acoustik OV1-4000D (Says 2200 rms, but ?), PA PS1-3000D (1700 rms, but ?) (is PA good?),

i think im deciding between a rockford t3000 or a hifonics thor 3000 any other amps you think would hit harder for the same'ish price. thank you

Just as the title says, I'm looking at the best amp for my money to power my single SSD 18. Currently I will be using my 700W receiver as my amp untill I get a new amp for christmas. Sundown seems to be super duper popular, and apparently the best amps around. But the problem is that for the money, I won't be able to get 800W RMS if I go with sundown. I know its probably not recommended at all, but I found a Boss Audio amp rated at 750W RMS at 4 OHMS for $155. It didn't have any bad reviews from what I read. But I know boss audio doesn't really make quality products (at least from what I have read). Hopefully there is something better for the money. I really want to ths s…

hey guys, im purchased a 18 inch fi btl n2...i need an amp thats stable at one ohm and is under $300..i was looking at some hifonics amps? are they any good? thanks, ben

i am looking for the best amp for under $300, i am looking for an Sq system, I have a Fi Audio Q12, and custom ported box, tuned to 32hz, I have a 2007 honda accord V6 EX-L. I was looking at Memphis 16-PRD 1000.1, and people have said that this amp is pretty good, but i want some more input. thanks C

Alright so im going to have a pretty big box in the back seat of my quad cab, 35w 31h 17d before displacement of the sub and wood. The cab in a 99 dodge really isnt big, so its a big box and big sub in a small space. What do you think the tuning should be? i want it to get loud and low, and i was thinking 30hz. (actually like 29.7 or something) opinions? Also the sub and port will be on the 31x35 side of the box on opposite ends. Or should i center the sub?

lookin at buying a new vehicle and im wondering what the best vehicle would be for 2 18" BTL's ?? iwas thinkin Grand cherokee but i dont think theres enough room, what vehicles do you suggest i check out?

Ok so everyone keeps telling me to go get the big 3 upgrade done cuz its a pretty simple way to relieve stress from numerous things. Ok so i go to my local shop today to get a quote and learn a lil more about what it takes to do it. The guy comes out and looks at my car and i tell him the 3 wires that i want to upgrade to 0g. so he comes in and starts crunching numbers on his calculator and comes up with a price of $263??? I almost walked out of the store right there haha but all the stuff was good quallity. all was RF power and ground wires and new terminals and rings and the whole 9 yards. but nobody every told me that i would need all this stuff for a big 3 upgrade. So…

FiQ 18 + AQ2200 at 2 ohm vs AQ hdc3 18 + AQ2200 at 1 ohm really confused and dont know with sub to get because I originally wanted the FiQ for its SQ but for $60 cheaper I can get something LOUDER...but how is the hdc3 18 when it comes to SQ Help would be appreciated

I am almost done my setup on my corolla 98 and I just wanted to thank everyone in these forums for helping me put this thing together. I'm running a fully loaded bl 15 off a sundown saz 1500d (3.7 cubes net volume), i have 4 cdt cl series components with the upgraded tweets, my headunit is an alpine 9886 and an sax 100.2 should be here through the mail this week (temporarily while sax 100.4 become available) all my wires and fuses are from knukoncepts. I have never owned a soundsystem myself,but I have many friends who have them and just this year i caved in and decided i needed to buy a top notch soundsystem without paying big dollars for a brand name. I've been slowly p…

I'm deployed to Iraq (9 months done, 6 to go) and I was starting to get serious sub bass withdrawals. I just got a great deal on a Behringer EP2500 for my HT setup. I was going to order a Q12 for my car when I got back but I had an idea. So I emailed Scott and Nick to see if they could build me a small sealed box and ship the box to Iraq loaded with a Q12. Scott said yes so I placed my order. I was getting impatient because I wanted to know how much more Fi needed for the box and additional shipping. Then it arrived today and it is amazingly in 1 piece. I've had a smile on my face all day. It is jury rigged with 3 adaptors inline running of my laptop but it still so…

What is the biggest difference between the 12 inch SSD and the 12 inch Q other than the 200 watts of more power?

whats the biggest size to have a sub reconed to? 18" ? and thers noooo way it could be made bigger?

Soooo I ordered my sub early morning monday and it still says billing information received on the ups thing... just wondering when it will be shipped out =( Invoice number: I-11383/00

So my grandfather comes down for a visit in his new car, one of those two seater fast driving Caddy's, nice car. He sits and listens to my system, seems to love it. Out of no where this 72 yr old throws me in his car and cranks up his radio. He has an SQ setup using 3 10" eclipse subs (not sure what type, but nice), and two sets of Rainbow Germaniums. That stuff sounded nice. For the first time I was listening to something that didn't just throw out so much bass that is almost all you could hear. To make things better, my old lady is makin me sell one of my trucks to get a car in the next couple months, meaning a new setup. I will probably be on here asking all sort…

Does any one have a design that they could /would share for a single BL slot ported at around 30hz? Thanks all! David

Well to begin, I will report on my expierence with FI customer service! I ordered through the site and paid with my paypal account, the site was very easy to understand and use! Once I ordered, I began harrassing Scott with all kinds of annoying questions. Scott answered everything I asked as best as he could, without complaint! I even sweated Ndmstang a few times, he too was helpfull and understanding. So all in all customer service was top notch. Tracking was so so, UPS sucks in my honest opinion, that has nothing to do with FI at all though! They rarely updated the info for tracking, it always looked as if my sub was just sitting around. I am biased though because I l…

Ok i just installed my system yesterday... Its not hitting at all. They guy at the shop said that it needs to break in a little bit before he adjusts it? I have a sundown sae 1200d and all 0 gauge wiring. Is it not hitting becuase its not adjusted right? I know that 1500 watts rms is ALOT of bass and should be LOUD, but its not hitting. So is it because the adjustment on the amp?

Is 1800 watts rms too much for a BL daily in 2.25 cubes at 32 hz? also how loud are these subs? this will be in a regular cab silverado.
