all hooked up to a good electrical system should i run the amp at full tilt or dial back just wonderin if the sub will take it for a daily beating and last

Recently Purchases a 10" SSD Fully loaded, Dual 2 Ohms, Standard QTS. The amp is a Kicker ZX1500:1 at 4 Ohms. Just curious as to if anyone here has ran an SSD in a T Line and if so what advice do you have as far as box size etc etc. ,Ethan

i bought 2 bl 18's d2's in 2008, one in october, one in november. Now i am wanting to run 3 18's but was told not to mix those 2 with newer bl 18. I got these 2 with cooling, flatwind and universal options. Do you have any older bl's in stock or stuff to build one? Or could I run a new one with those? thanks

I currenty have thhe two subs in a 4th order blowthrough off of a 4500d on 16 volts. Gains were set around 1/2 way and it pounded for bout 4 days. Then I decided to turn it up a little. Between 1/2 and 3/4. Now the subs don't seem near as loud to me..could it be I'm just gettinng used to them? I'm gonna check with the dmm tomorrow and read the coils and see how many watts the amp is putting out...I hope I didn't mess anything up:(

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?

Scott at fi car audioi sent me this enclosure.. http://yfrog.com/eq23cuft33hzj Is this a good enclosure? Is it going to be very loud and clear?

I am running an AQ-1200D @ .7 ohms to a 15 BL and my friend installed it yesterday and set the gain on the amp a little less than half way and when i turn the bass knob about 3/4 up and turn the volume up to like 25 out of 35 the clipping indicator on the bass knob illuminates on and off with the bass hits on some notes. its aggravating the shit out of me because I just spent alot of money and I dont want my shit to fuck up. He told me the amp could be too small for the sub or the HU is sending out bad waves to the amp. It sounds amazing, dont get me wrong. I just wanted some advice on how to get the clipping to stop. I have a Kenwood Excelon KDC-X792 head unit and it has…

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.

I was driving around and all of a sudden my btl quit. I have tried to rewire it using just one voic coil and noluck it wont even turn on... Any idea?

Sorry if this is covered elsewhere but I can't seem to find the answer im lookin for I've got two alpine pdx1.1000 rated at 1000w rms. One of these would be underpowering a btl rt? And I couldn't run two to one sub? What would you guys do? I have an audi A4 so only one huge box would fit in my trunk

how does this look. the sub will be in the trunk firing into the cabin with the port as well I'm also debating between the sundown 2500d and the audeque 3500 to run a 15" Fi btl at 1 ohm my electrical consists of at the moment optima red top up front optima yellow top in the rear, big 3, 0 gauge through out

This is my setup: A US Acoustics USB-2150 rated for 450 watts x 1 @ 4 ohms powering an 18" Fi Audio IB3 at 4 ohms. I have a seemingly solid install now, but my score has stayed the same, 132 and change on both the termlab and my spl labs lcd bass meter. Check out my build HERE. I decided to test the output of one of my sub amps. I tested with tones from 25hz to 65hz. I checked the AC voltage output of the amp. Simultaneously I checked the output amperage to the sub at the positive wire to the sub. With these numbers I calculated the wattage by multiplying the volts times the amps. I also calculated the impedance by dividing the voltage by amperage. This is what I got 25Hz…

Hi, sorry to cross post. I just put this in the wrong section the first time... This i what i'm working with: 2006 Dodge Ram 2500 Diesel Quad Cab Big 3 upgraded 2- 15" fi BL 2- kicker zx1000.1 3/4" MDF custom center console box with 5.6 cuft of airspace after sub disp, bracing, and port. Would love to have a bigger box, but space is LIMITED. No divider between subs/ subs share air space Single Slot Port is 15.5" x 3" and 14.75" long (around 32 hz?) Subs will be down firing and port will face up. Definitely SPL Questions: 1- Are the port dimensions correct for a 32 hz tune? I keep getting different measurements depending on the port calc I use. I think carstereo.com…

I know that Fi recommends ported for BL's, but for space reasons, I'm wondering if I could do a BL in a sealed box with one of TCSounds PRs (passive radiator). This will be running off an USAmps 4000DE (1600wrms). For space reasons, my plan was to go with a 12" BL in a sealed 2.5cf box, with a TCSounds 15" PR (or VMP as they call it) http://www.parts-express.com/pe/showdetl.cfm?Partnumber=293-682 http://en.wikipedia.org/wiki/Passive_radiator_(speaker) For those too lazy to click on the PR link "Passive radiators are used instead of a reflex port for much the same reasons—to tune the small volume and driver for better low frequency performance. Especially in situations i…

I picked this sub for cheap and all I have to power it is a sundown that pushes 600rms at 2ohm just was wondering if it would be okay to give the sub such low rms compare to what it could handle. or should I just get another amp that does 1000 at 2ohm. Also I have kinectic batteries with a 120amp alt wondering if that be fine or would I have to upgrade it anything. 12.8v and 14.5 at startup i think.

which one would sound louder (spl) because i like the idea of having an 18 but i only have room for about 5 cubes so after diplacement and all that it would be in the 4cu/ft range like i know it would have more cone area but in a box too small for it btl would have the cooling and himax coil options

right now i have a fi ssd on an aq1200d but i want to get a btl and maybe score the free cooling option before july 29 but i haven't been able to sell my aq1200d so i'm thinking bout keeping it and just buying another one and strapping them together but i will only be able to run it at 2 ohms so what would be better 2 aq1200d's @ 2 ohms or 1 aq2200 @ 1 ohm ? and how would i wire the 2 aq1200d's? this is my first post so sorry if it's messed up at all lol

Hey guys , i want to build an sq box for my FI BL 10 ! I hope you can help me with the port an the size of the box ! Thanks for helping me ! Nice regards

I am running 3 Fi Q15's. The box is 10.2cuft internal after port and sub displacement. The port is 5" x 28.5" and 26.25" long. Is that a proper amount of port area? That should put my tuning right around 32hz.

okay so i have an old three stack magnet btl twelve if i bought a new single stack btl 12 would it be worth it thanks.

hey guys heres the deal, i finally got my ported box completed and installed the D2 15" BL, hooked up the amp (aq1200d) to 1 ohm, saw that my fuse is blown so i had to use my friends to see if everything was working.. the amp was showing power, and hooked up a capacitor just to see and it was getting the proper volts, but NO response from the sub, no movement at all. We were soo confussed, everything looked properly installed. just wondering if anyone has any ideas! Please help, i appreciate any given. I miss the bass also how do i properly tune my amp, and where do i put the knob angled at on the subsonic, i need it set about 30 hz which is 2 under the box tuning, but t…

I have a 2006 Nissan Sentra (1.8L) that has the stock alternator putting out 80 amps. I am looking to soon be running 1200 watts RMS through the system. I know I will have to do SOMETHING with the electrical system. But what? New alternator? Extra battery? (Big three is a given) If new alternator, would the one in the link below be suffice? (20 extra amps) http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=120530973171&viewitem=&_trkparms=algo%3DLVI%26its%3DI%26otn%3D2&category=33573

Since both the Fi BL 12 and BL 15 are 1000 watts RMS, and I have about 1200 watts to play with, which should I get? Would there be a huge difference? And on a completely unrelated note, how do you guys go about bolting down your enclosures in your trunk? I have a 06 Sentra and below the carpet in the trunk is the spare with a piece of cardboard over it. Now there is about a foot of exposed metal running down both sides of the trunk. Just curious about how it's done. *Guess I should have asked first, will a box for a 15" BL fit in the trunk of a Sentra? Thanks.

Hello, today was one of the worst days ever, and what happened I thought never would, but it. So I'm here today to ask for advice. I was mounting the sub (15 fI Bl) and my hand slipped and ripped the outer foam ring around the sub. It's closer outside towards the steel ring where the holes are, and you can't see it unless you fold the ring. I managed to stop and retract and not run the whole screw drover through, but it did rip. Upon inspecting it closely I lost no material, it's just a 1/8 inch long tear. My question is this fixable? In been reading like crazy and can only see two common solutions. Silicone or superglue. I am leaning more towards the silcone because it w…

I'm seriously considering getting a Fi BL 12 and was wondering if the amp I link to below this would still be a good choice. Thanks in advance. http://www.db-r.com/sell/store2/index.php?main_page=product_info&cPath=65_67_69_105&products_id=248
