1- when are there going to be stickers 2-when are you going to make a badass hat?

hey guys, i ordered 3 Q 18'' subs which i intened to use in a ported application but for some reason not sure how the high QTS option was selected..and in the options it says this is for only sealed applications..so i sent a email thinking i would be ok since it says there is a 30 day wait time but i just got a email saying my subs have shipped so im not sure if they got my email in time and made the change or not, so my question is how bad will it sound if i still throw them in a ported box even though they say the option is only for sealed applications?

My enclosure is 1.3 cu ft sealed, should I add some poly-fill to soften the boom a little if so how much should I use, 1lb, 2lb, somewhere inbetween ? Thank you.

I am running (2) of the 12SSD's in a ported box at right about 4 cu. ft. net and its tuned to about 32 hz. power is rated Zapco 1000W if I can get another cu. ft. What can i expect in the characteristic of the box? More efficent? more boomy? I do not want to make it sloppy, it's already ported which is a trade off for me to begin with. Or I might consider the max sized sealed box. How would you compair that to my existing ported box? thanks

I love my Sub and plan on purchasing another one but ever since i purchased my 18" SSD back in December i sort of drifted away from the forum and keeping up to date with everything that was going on with FI. I have read different articles saying there are new lines for the BTL and i think BL but not sure on the Q and SSD. Well anyways i plan on purchasing another 18" SSD soon and my first question is, is there a new line of SSD subs and if there is my second question is, will there be a problem if an old SSD is in the same box as a new one.

i have a FI bl 15,cooling,daily, universal d1, im (thinking of) adding another bl to my car (not like i really need it ) but is there i could wire 2 d1's down to 1 ohm?( wouldnt it end up at 1/4 of an ohm? or 4 ohms) i don't think you can but, hey theres always hope(or none) but i was thinking about getting an excessive amperage alt like a 250 amp, run 0g wire front to back add a kinetik battery all KnuKonceptz wire, with maybe a crunch or hifonics amp Ideas or comments?

it doesn't make sense, when i chose the p chamfer option it added $10 then i chose the cooling option too and it doesn't have a price. and there's a note that it i chose both p chamfer and cooling, uncheck the p chamfer because p chamfer is incuded in the package of the cooling. in short, if i get both options, the p chamfer and the cooling, i will get it for free, but if i only get the p chamfer option, i need to pay addtl $10 for it. can someone explain this for me, thanks. i'm also planning on getting the universal option, my question is, if i get this option will there be any changes in the performance of the sub? or side effects?

I'm thinking about buying 2x FI 12ssd's and was wondering what amp would be the best choice for these subs?

i am getting a 15" Fi Audio SSD15 sub and i am wondering what amp i should get. i dont know if i should get one with 800 rms or 1000 rms. also, what are the best specs for this sub? Also, will i have to do the big 3 or anything else to handle this wattage? i have 98 navigator. thanks!

I guess my original post got lost, but was looking for some help with my choice of amps. I have a 2000 Nissan Maxima, and I have one BL 15 now and I want to get another one. So for 2 BLs I know I will have to upgrade my amp. I dont have a HO Alt, so the SAZ 3000 would be out of the picture (right now anyway) how would a SAZ1500D push 2 BL 15s? what other amps do you recommend? All name brands are welcome. Also how much do HO Alts usually run? Thanks

I think I'm gonna add another sub soonish and am hunting for an amp. My budget will be around $150 and was thinking 500 watts total. I'm going sealed. I have ~160 watts on this one now and it gets loud which is why I was gonna add another with a little more power each. Or would I be better off just getting a bigger amp on the one I have. My budget may go up some just depends on the amp. Definitely not over $200. I have 4ga wire running and will need to put an amp on fronts. I have a 4 channel now running entire system. My car is a 2011 Honda civic systems in Sig. If I'm a noob and you have questions just ask

is my rockford fosgate t20001bd at a 2 ohm load too much for my 2 q18 d2's? its a 2 ohm load at 1600wrms. thanks!

i have a budget of $500 for an amp can anybody tell me what would be better for a 18" bl and 18" btl i will appreciate any help from anybody. thanks, Jose

Im wondering what amp to run for a dual 2 ohm btl 15 with cooling, HiXmCoil, Daily, I Heat Ring. what would be the best bang for the buck? My budget is around about 600 but will pay more if its worth it. Thanks

I was looking into the hifonics amps for price reasons. Looking for an amp around or under 200. I was thinking about the hifonics brz1200.1D. Opinions? This is just going to be a daily driver build with one BL12. Any help is apreciated. And just for kicks, the car is a 1987 Suzuki samurai.

I am new to car audio and need some help with what i would need for a subs as powerful as the BTL's. I heard you need a charging system for your amp to keep up with it, but im not sure what that is. Also what kind of amp would i need for, lets say 2 15" BTL's

Im getting a Fi SSD 15". I need to know what options to get and what i should get for an amp. Its GOING TO BE A DAILY SUB THAT WILL BEAT TO ITS MAX EVERY DAY. I want to go with the hifonics brand amp and wonder which is right. I myself think it'll take 1,500 rms no prob. These are the amps im considering... I want to get a 4.0 cu ft box tuned to 32 hz HIFONICS TXI1508D ---------1,500 rms HIFONICS-BXI1608D ---------1,600 rms HIFONICS BXI1208D----------1,200 rms All are 1ohm stable Im going with hifonics cause they are affordable but open to others. i only have like 400 for an amp.

alright guys i need some help on choosing a amp for my sub. i was thinking of getting a crunch 3000 pro 3000 watt rmms at one ohm for 439.00 is this a good amp or should i look in a different direction. i fogot to say the btl is fully loaded

So I just recently ordered a fully loaded Fi Q 15" and now I need to decide on an amplifier. I'm thinking either a Hifonics HFi2000D or a Hifonics Brutus BRZ2400.1D. I will be running them at 1 ohm. Do you think 2400 watts rms is too much for a fully loaded Q? I think it should be okay, but I would like to hear some other opinions.

What are some good amps that can put out 1600RMS at 1 OHM. Please post the price of the amps if you can. Dont want to spend to much.

i currently have 2 12" Fi Q's in a monochambered enclosure tuned to 32hz for maximum SQ but no amps from what people have told me (2x) sundown sae-1000d should be perfect but my question is... if both subs run 1000 rms each, would it be better running (2x) 1000 watt amps or (2x) 1500 watt amps??????????? also, which amps would be ideal if money wasnt an issue? preferably brand name and specific model. thanks a MILLION!!! NOW HELP ME BUILD MY DREAM SYSTEM!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I have a 12" bl with a kicker zx1000.1 and an optima red top for a battery and even with the gain only half way up I am getting headlight dimming and my amp is clipping. I have a friend with the same amp and the 15" bl and his doesn't clip and he has a weaker battery so I have no idea why mine keeps clipping.

well..i saw alot of guys using behringer's ep 2500 for powering dual Q 18's(my plan) in setups over on hts forum..however..i know that the behringer doesnt put out 2500 rms maybe somewhere around 1000 so i was thinking ..maybe the dayton plate amp might do a better job and give me a little extra features...any ideas or opinions??all is welcomed..thanks

A buddy of mine has an Orion amp, I'm not sure on the model of it but it's a 2400 watt amp and the yellow ecp light I think it is comes on and there is no output from the sub so I'm just kind of wondering what the ecp light is for and why it is on.

Will the new sundown sae 1200 coming out in november be too much for a 15Q loaded?
