Fi Technical

So I got a 12" Q last week and I LOVE it but my sub cuts out or has alot of background noise and i hooked it directly up to the amp and it plays fine and I am figuring that its the speaker terminal because when i put my finger on the negative it starts to play but when I take my finger off it stops? and In addition the - wire looks charred on the inside connecting to the terminal so my main question is has anyone else had this problem and what would be a good solution?

Hi, Ive got a MTX TA81001 amp that pushes 1500 watts at 1 ohm and im going to run a 15 inch Q. Do i need to get the BP option or will it be fine without it.

Scott, I just want to start off by saying thanks for the fast delivery of the recone for my sub it made it here in time for me to take 1st at usaci show in Omaha with a 141.7. But, now I need to build a competition box tuned to around 43-48Hz since my car is tuned to 45Hz. any help with this would be great. My email is [email protected] for box deminsions and print off sheet. Thanks again for all of your help.

would i be fine if i just did the big 3 upgrade with 0 gauge wire. I have a 12bl fully loaded and a sundown sae 1200d.

Alright im not realy sure about this so ill ask it here. I ordered 2 18in D2 Single stack recones with highxmax coils but there not flatwound. Is my order wrong? im under the assumption that these should be flatwound for better power handling and cooling.

Well, my box for my truck is gonna have to have a few pretty tricky shapes in it and I need to be sure that the magnet will clear on one side thats gonna be sloped.... I just need to know how wide the mag is on the ssd and if you don't mind, the Q as well... Thanks...

What is the Xmax with this option? I only see the 28mm on their website and I assume this is without this option.

I have an X12, 4ohm with BP power option, in a 1cu ft box after displacement, running on 350 watts. I need to know about what frequencies to set to LPF and subsonic adjustments on my Mono amp to best meet the specs of the sub. My subsonic will adust from OFF to 50Hz and the LPF adjusts from 40Hz to 220Hz Thanks Steve

i am planning on hooking a fi bl 12 up to my kicker zx 1000.1 amp which is 2ohm stable. do i buy a dual 1 ohm sub or a dual 2ohm? please help! thanks

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?

Ok right now I have the Q 15's and I've gotten used to them so I want to upgrade to the BL series. My question is, ok i want the same freqency response as the Q's have cause I like how they perform down low, but I need to know which options in the BL should I go with to have a good daily woofer? I was thinking of going with the cooling, flatwind, daily, and universal options because I am not looking to do any competing just some really bad street beating. But Im a little skeptical about the cooling option because it says that there is less metal in the motor thus making it a little weaker? So should I just go with p/chamfer, flatwind, daily, and universal because I dont w…

Putting a brand spankin new 15" Q dual 2ohm in a 97 honda accord. This is for daily music kinda stuff, no comps, I just want it to be clean and wang on the lows. I was wondering if anyone has had experience with these trunks and knows what can fit in em. I am thinking that ported would sound best but am open to all suggestions. Also, if ported should I go with slot port, aero, other? If my measurements are correct, Max we're looking at 17 tall x 32 wide x 22 deep. Will a ported 3.0 ft^3 sound as nice as 4.0 ft^3? Any help would be great

I'm currently looking at components to go with my 12" BL. I'm going to either go with Rainbow SLC 265s or SLC 265 Kicks. What I was wondering was with my box tuned to 32 Hz would my BL get loud enough up to 80 Hz to be able to have my high pass at 80 for the Kicks? Thanks

I was just wondering if it was possible to replace the push terminals on the BTL with the terminals you need a hex key to open and close, could someone also tell me what gauge wire will fit in the push terminals. I don't have it yet, I'm just asking if its possible.

Hey guys, bottom line is i have designed a few enclosures and they sucked. I'm not so bad on the building part, just the calculating port length and area and volume and stuff. I have a 15Q and was wondering if someone could design me a box of around i dunno 3-4cubes tuned to like 30-33hz. My trunk limits the box to be like 16-16.5 inches tall (otherwise it won't slide in) and uhh yeah thats the only real limitation. Thanks in advance.

hello im building a sealed box for 2 q15 subs in my 1996 honda civic hatchback, i have a few questions? 1.... should i have each sub in seperate chambers or the same chamber? what is the pros and cons of doing either? 2.... what kind of difference in sound should there be between the largest recommended size encloser and somewhere inbetween? and whats the pros and cons of each? 3.... what kind of effect would there be having the subs down facing? Now for my front stage i want some more midbass, i have 2 different types of 6.5 inch woofers, infinity perfect 6.1 and older set of diamond audio hex series, i was thinking of putting the infinitys in the doors and getting some …

I have an ssd 10 under the back seat of my nissan titan and im havin problems with it hitting the grill i have on the box when it pounds. Ive been adding wood to create more space between the sub and the grill but i was wondering if there are any other techniques i could try. Any help would be appreciated.

I just bought two 15 fi Q's with BP and a aq2200 to power them at one ohm. Running 0ga and doing the big three also plan on another battery and a HO alt soon. My question is with the box setup,its my first time buliding one and would like to do it right. The max demensions are H 16 W 42 L 28,.(ported) i was thinking around 32 or 33 hz.. But i could be wrong? i want the lows and alot of bass but sound good aswell. my other question is should i put a divider and run a port for each sub or have them both to one port? Any input is helpfull thanks

Has anyone used the IB3 series subwoofers, specifically the 18" in a home audio open baffle application? If so, what were the results and how much eq was needed, if any? If ordered new, does anyone recommend any modifications during manufacturing that would improve OB performance? Thank you!

I have a 12in fi bl fully loaded and a sundown saz1500d with all 0g wire and stock electrical. My alternator is 110a. Im not sure what I will need to do to see full power from the amp. Would the kinectic 950 be enough for an extra battery in the back?

Any reason my first SSD with D1 copper coils suspension is way looser than my newer one which is about a month older? I know there would be a difference because of the break in period and that eventually the new one would soften up slightly to sit like the old one but the newer one has a firmer suspension as oppose my old one and worries me that it may be a possible problem with my old sub. I got the first sub in february and the second one in march and have beating on them since day one but the second seems to have a better suspension than the old one? Please let me know what the deal is?

I will soon be running a fully loaded BTL 15 in a 4 cu ft ported box. Which tuning would be better SPL wise, 45, 48, or 50 hz? I know it is a bad question because it varies, but what has been a good SPL tuning most people have been using? Thanks Dustin If it would be best to build a bigger box would a 4.5 cu ft box after displacements be a good volume for SPL? Thanks. Dustin

2004 Monte Carlo a pair of 18" fully loaded BTL's a pair of Power Acoustik A3000D amps one lonely termlab 500 pounds of wall... 153.6 @42 hz windshield 152.5 @38 hz MECA reality stand 151.8 @30 hz winshield ...and just for Meade... 150.6 @27 hz all in all these subs are very impressive and tough. the monte carlo lacked a lot of the needed airspace to make this setup do the 155 i was projecting but a little added wattage will fix that issue (BTL's like power and dont be afraid to give it to them). innitially there was some metering issues getting the car to go over a 150 which is the main topic of my post. 40…

I ordered my BTL's on July 28th and i got an email saying they accepted my pay pal and i got an invoice number. After that i got no tracking number or shipping confirmation. I waited about a week and decided to email them and i havent recieved any response... I tried "[email protected]" "[email protected]" "[email protected]" and "[email protected]" Any ideas on how to reach them?

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
