Fi Technical

I've been trying to decide for weeks what i wanted to do for an audio set up. Im pretty sure i have it figured out. Im thinking about ordering it all today or tomorow, so i could use some fast help. Im getting the sundown 1000d and 1 12'' FI sub, i would go fifteen but i don't think i could fit it. I'm stuck between the FI ssd, or fi bl. I listen to mainly rap, and heavy metal(alot of double kicks and what not) so its a daily sub. I like boomy deep bass, i don't care so much about higher notes but the better one could hit them the better. I was also wanting to ask about enclosure suggestions, im not too worried about loosing all my space in the back, but if possible i wan…

I have 4 fully loaded 18 btls in a 20cuft ported enclosure..dual 1 ohm subs.. I have the option of using 1 or 2 jbl a6000 amps to power them. My installer thinks that using both amps will blow the subs. He hooked up both amps and said the woofers started smelling. When he used 1 he said it was actually louder. I think he may be trying to save me from replacing subs over and over. Will using both of theses amps eventually blow the subs? If I get 2 more and put 3 on each amp will it see a 4 ohm mono load...something like the JL w7s? Thanks for any help

Hello, i'm looking at getting a Fi Audio 12" SSD sub. So I was wondering if a square port of 29.25 is alright? My box is 2.1 @ 33Hz. Thats after all displacements. I haven't build a ported box before, so i'm learning how to.

ok so i hooked up my new fi ssd and my kicker 750.1 amp. ok so the problem. when i turn the volume down all the way on my kenwood kvt911 headunit. i still can hear a little bass. then when i turn it up its not loud at allll. i turned the bass up on headunit and still the same thing im soo confused someone please help

could someone give me advice on a box for 2 BTL's 12?? it'll be powered by a 3500D or 2 2000D's. thanks

For some reason outside of my power my 08 Bl with cooling caught fire. I was on my way home from work about an hour and a half ago, i smelt something kinda like burning leaves so I turned the radio off and pulled over and opened the hatch of my jimmy and the sub was on fire. I could see this bcuz there is aplexiglass window on the front of my box... I have no idea how or why it did this, it was on fire at the spider btw. The amp wasn't warm nor the wires... The amp isa sundown saz 1500d. 0g wire, 12g speaker wire. Itwas only playing for about 5 min when it all happened. I think the warrenty is still in effect, but I'm not sure if that is even covered. The gains are all se…

Ok, so I finally finished stage 1 of my install today. It's gonna take too much time for the custom fab needed for my components to fit in my door so I used a Line Out Converter to get me by. I couldn't change out my HU because of the factory amp and it would cause the speakers not to play and there is no harness for it yet. Anyway, back to the point of the post. So I have my Q in a sealed box with about .8-.9 cubes after displacement. It's a cheap $20 prefab box. I'm just not happy with the current output of the sub. I've seen 10" Q videos, sealed and ported, where there was trunk flex and the rear view mirror noticeably vibrates, and this is only on 1000 watts. I'm runn…

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

Well here it is. A freind got a new 18inch btl, and he was throughing out his 10. I figure, since I have some left over LN from a computer cool, I would design a box and have LN cooling the sub. Yes this will involve some major work on modifying the sub. This ever been done ?, I just want to run 8000rms to it. And not have er burn. This is my first post aswell, and ill be ordering some subs later on . I figure if I vaporize the LN and have blowing through the sub, that it atleast not kill it for 10 seconds of playing. Crazy or worth a experiment ?

I have Term-Pak and am looking at the graph for a box for my BTL It looks horrible. Is it just me or does the sub just plot poorly? I used the specs off the site. I'm using a model of 4ft^3 @ 32Hz

Ok so im about to order 2 12" Fi Qs and just want to know what setup i should get. im thinkin on getting a JBL GTO14001 amp for it, is that ok? also... i need to know if i should get an extra battery or cap for it, if so what kind?

Allright i got my btl in and the dustcap got hot really fast and i mean hot hot i have 8ga wire running to the speaker and 1/0 ga ran to my optima back to my kinetik 2400 and ran it full tilt and this happend its a duel 1 fully loaded and it is in series to make it a 2 ohm load the amp is a Rockford Fosgate t2500.1bd everything seems to be fine i mean i have not "Broken" it in yet..need some help does it matter which terminal i use to run series?

I want something that will flex glass but that i can us daily. i was sold on the btl 18" but will it handle everyday abuse? Any help would be great thanks

Ok, I am a ported enclosure built from pound that sound for 2-12" Fi Bl subs. I built a cardboard box like he asked as big as possible to fit in my trunk. It ended up being 39" wide x 13" Tall x 15" deep. This was sitting on the ledges on each side of the trunk and the spare tire hole being empty on the center. The box has to be dropped in from the top and has about an inch and a half gap on the top, and the side facing the rear of the car. Will this be enough space for those subs? I notice it asks for 1.8-2.5 per sub so I think I am a little small unless I would extend the bottom center of the box down into the spare tire well. HMMMMM?

I Have 2 12 Inch Fi BL's and i dont know what amp i should go with i was leaning towards a sundown audio 2000D but also was looking at soundstream PCX 2000D .. any suggestions on what i should do ?

I have 4 18 inch fully loaded BTLs that I will use for a daily driver. Can anyone help with how many cubic feet each sub should get? I want a ported box and will power them with 2 jbl a6000 amps. The manual says 5- 8 cubic feet but what size should i go with?

Ok i have a 03 silverado extended cab and im wanting to put either 2 12 q, or 2 ssd under the rear seat in a sealed box that has .82 airspace for each chamber and a 7 in mounting depth. i dont know what subs would be best because i really want something that would make people stare lol any advise would be greatly appreciated

I have 2 12" Fi SSD's with copper coils coming soon and I need a box for my Charger and found this. http://cgi.ebay.com/2006-Dodge-CHARGER-SUB...%3A1%7C294%3A50 Would this box be ok to use or should I have a shop make one? I also found a ported one http://www.onlinecarstereo.com/CarAudio/Pr...ProductID=21319 I mostly listen to rap but also listen to rock, death metal, etc. if that helps

Alright so i have a BL 15 in my car right now. When i get money i plan on buying another one. But the one i have right now is D2 instead of reconeing it to make it d1 i was thinking could i just buy another D2 and then just buy another SAZ- 1500d?

Gday all I am running two FI Q 12" D2's in a daily driver with a box that was built for it by a local car audio installer using a single round port. Sounds reasonable but no where near as loud as I expected from these speakers. I am driving them with a Hifonics 2k rms amp Boot mounted Optima inline with another optima under the hood. Also have a 2.5 Frd Cap. This is a boot mount install in a Aussie car Called a XR6 Family sized four door sedan.. ATM I have the speakers behind the back seat pointing into the car and the port facing the same way. Metered this setup at 132.5 before i upgraded the batteries seen alot better scores out of single speaker setups with similar siz…

hello, well i decided to put my (4) Q 15in. subwoofers in the bed of my chevy s-10, standard cab, it will be a blow through, has anyone done this? where can i get some information on how to do this? where i can find the boot to put between the cab and box? well thanks for your help, Brian

I have a 94 Ford Lightning and currently have a Alpine CDA-9883, Kicker KS components,4 gauge wiring, 12" L7 and Hifonics 1508D amp. Im wanting to get as much bass possible out of a single cab truck without cutting my truck up. So im looking into the BTL 12".Should I go fully loaded? I will be playing this sub everyday. At 1st I will have it running off my Hifonics amp putting out 1500rms at 1ohm. Do I need the dual 1 or 2 ohm to run it at 1ohm load? Then when I get some more money ill get a better amp. How much power can a fully loaded BTL 12" take daily? Im thinking about the Power Acoustik BAMF 5500 amp putting out 3200rms at 1 ohm. The biggest box I can fit in my tru…

I am wanting to know if these numbers are sufficient for a vented enclosure for for a 12" BL. I will have it hooked up to a MTX TA81001 A 1 ohm in the trunk of my 06 Honda Civic. Any suggestions would be greatly appreciated.
