Like title says........what is the recomended port area for an X 10? It will be in .75cuft using aero port...............I'm thinking I read a 2.5" was enough once just need confirmation.

Alright, vehicle is a 99' infiniti i30, 4 door sedan, I have two 15" Q's on a crunch 3000d-pro. The enclosure is 7.2 cuft after port, and displacement, tuned to 32.5hz. It gets pretty loud, but kind of a empty not real full sounding bass. The enclosure is built into the trunk with the woofers mounted invertedly, so that the magnets are pointed toward the back of the backseat. the port is firing out of the top of the box through a hole in the rear deck. It sounds like there is a lot of cancellation, and when I open the trunk and crank the system it sounds way better and hits the lows way better. I understand this is some sort of phase issue I believe, and have had o…

Ive got 2 BTL 15s and i wanted to make sure my calculations were correct before i started building. The total room i have to work with is h=23 w=24 l=39inches. Total internal volume is 10.5 cubes, and after all displacements i have 8.65 cubes. the port dimensions are h=22.5 w=4.5 l=18.4 which should make the box tuned to 33hz. can someone check this for me to make sure i didnt make any errors. Thanks Keith

whats the most power you could safely put through a btl 18 loaded, and not blow the coil? im just wondering what some have tried and found to work where as someone might have tried ____ and blown said sub.

Not at the same time! I have two boxes built for my single 12BL. (D2, loaded, daily) One is 2.5cuft @ 32. Slot port. Homemade The other is 2.0cuft @ 32. Kerfed port. PTS They are both designed around the 12BL t/a parameters. Two questions. Is the BTL a substantial upgrade from the BL? Could I use the 12BTL in the same box which was designed for the 12BL?

How would having an enclosure bigger than the recommended box volume affect my system. I am planning on ordering a 12" SSD w/ copper coil. I am trying to save money on this system which isn't something I'm used to since I usually go all out. I was thinking of buying an already made enclosure to cut down on costs. I'd like to know how this would affect the sub's performance. Here's the box I was looking at: http://sonicelectronix.com/item_7521_Sonic...Box-+1SA12.html Thanks!

Both setups will be run off of a Sundown Audio 2000D amp. I only have a space of 1.1 cuft per chamber to work with. I mostly listen to rap and want these subs to be able to lit the lows well.

I've got 2 15" BTL's and the tinsels have snapped off. How can I get some replacements?

Hey everyone ! I got the aq1200d and the 15" BL ready but i made a ported box that i want to make smaller for more room in the trunk and its just a pain to get in. I was just wondering what is the smallest ported box measurements I could use to get as much as i can out of the sub while being tuned to around 32-33 hz. Please help! thnx

is it ok to trace around the inner black gasket ring that comes with the subwoofer to get the size for the cut out hole?

hello, ive been looking on her for the past while and only see box designs made up for 1 btl 18. does anyone have anything made of for 2 of them? thanks

OK, I'm going to buy 1 18" BTL today and I need to know what options to go with. I want to compete in SPL but I do sometimes want to be able to listen to music. I'm running it with a SAZ-3000 and I don't ever plan on adding another Sub. (I could never fit another) Yup so what options should i get?? thanks

ok so what im gunna do is put a single 12" BL into my f150....i have a bench seat in the rear so im gunna fold the short side, which is behind the passenger, and put the sub box there....i have approximately, 18" wide 16" deep and about 20" in height...the height is flexible tho....i have a kicker zx1500.1....can any one please help me design a box? thank you

My tahoe was rear ended a 2 weeks ago destroying my BL 18s. I had just purchased a RF T2500-1 and im awaiting my second. I have an Avalanche now and i want to run 3 dual 1-ohm BL 15s. My question is will the two 2500s be too much power for the BLs? Also, is there any problem wiring the subs in a "single voice coil per amp" setup, ie: 3 subs, 1 voice coil on one amp, one on the other?? Im kinda new at do-it-yourself car audio when it comes to complex wiring, so any help or advice, good or bad, is welcome.

I know people are going to say it depends on my application, but what would be a good starting net volume for a box for a single Team 15. Running on a DC 5K with 2 XS batteries and a Northstar 170ft. Do these subs like bigger enclosures? I will be slamming it daily but also doing some SPL. I'd like to tune it around 33hz. Thanks in advance.

I have a 12" BTL with pole chamfer and my Memphis MCD2500 amp is coming in soon. I want to get everything ready so when the amp arrives I can install it right away. This is my mustang 2004 stock electrical: 130-amp. heavy-duty alternator 540 CCA heavy-duty battery Battery amp hours (58Ah) Battery-rundown protection I will be doing the big 3 wire upgrade with 1/0 gauge wire from batt to alt to ground. Besides that, what else should I invest in? I'm trying to keep it as budget as possible. Thanks. PS> This is my daily driver.

So I got 3 15 in dual 2s wired in series tuned to 33hz on an audiopipe 30001d amp isn't turned up a little under half no clipping and as normal subs gets a little warm never hot enough to where u can smell the coils burning up. Now my issue i ran into today Is I was listening to them going to lunch with no problems and shut the truck off and came back out and just turned system on and how I can describe it is one of the subs instantly started to make a distorted rattling noise... kinda sounds like the sub is farting all lower frequency but not noticeable at higher frequencys. I pulled speaker out and the coils dont have any noticeable scratching or rubbing.. Now I'm just …

What is the lowest amount of watts to feed a 12" Fi Q and still get decent/good performance? I'm shopping for an amp and want to see what my options are.

So this is how much room I would like to use, but I have more room if necessary (I need some trunk space :laugh:) My dimensions are 33x21x17 and here is a picture with how what space I would like to take up. Just post your input on if this is good or if I should add more space for the box and how much! This should be around 6.817 cubes without any displacement. (btw this picture isn't mine I just googled what an 05 equinox trunk looks like, and no those side panels do not come out) hmm for some reason the picture came out a little blurry, but I think you should get the point and for the height I can also do up to about 21 inches so if i wanted to mount the sub back i cou…

I want another t-line in my truck. I had a dd 9515g, it didn't hold up. I will have 3kw on hand. What options on the 08 model BTL would get where i want to be with suspension, cooling, and power handling, as well as x max........If a combination of stiff spiders was needed then that would be ok as well. I just don't really know how well they will handle this type of application. It a 2006 nissan frontier(the big ones) xtra cab so i have a decent amount of room as my backseats are removed. advice will be appreciated. Jason

I am looking to build an enclosure for my 4 12" fully loaded BL subwoofers and was wondering if 8 cubes after displacement and everything is large enough or too large? I want to tune to 32hz as well. Please chime in with any ideas if you have them?

Hi, I am currently having someone build me a box and they are looking for a cut-out template to cut the hole for the woofer. I gave him the cutout diameter but he wants a template to be sure. I can't seem to find one on the website. Do Fi offer one?

I need box plans for a Fi Q12 (dual 2). It going to be powered by a Sundown 1000D. I want it to get loud but also have SQ. So Im thinking tuning it to 32hz. Fi recommends 12-16 square inches of vent area per cubic foot of volume. The demensions I want to use are 14.5 H, 28 W, 18 D. (can change alittle)
