Fi Technical

Has the title states, how do I get a 1 ohm load with 2 btls? My first previous subs where dual4 so I wired them in parallel. Do I need dual1 ohm? If so how do I wire them? Thanks.

Besides the voice coil, what are the differences between MT and BTL softparts?

i have a kicker zx1000.1....1000wts rms at 2 ohm planning on getiing a dual 1 ohm 10 inch or 12 inch bl for an 2001 eclipse need the recomended specs for the 10in bl and 12 inch bl.. which sub would be better for my setup and car?

what fi specifiacations (dual voice coil, hixm, etc) shoud i pair up with a 2600 rms hifonics?

I was wondering if 140in of port is to small for 2 of the Bl 18's? When I build my box the port would be 20h x 7w x 12d that would be 32hz. The box would be 40h x53w x14d. Should they be tuned lower or higher? Thanx Jason

im redoing my room and i want the fi revolution picture you see when you first go to the website in high resolution cuz my teacher is gonna make me a laminated banner for my room and i cant seem to find a high quality picture or the picture anywhere for that matter i looked everywhere and cant find it and now im asking around is there a way i can get the picture emailed to me or someone know a website i can get the picture?

scott i have 3 18's but 1 only has 1(the other 2 are fine) of the voice coils that works, there d1 coils what should i do

http://imgur.com/a/lNcLR#0 i have two sets of images its this album. a 33hz tune and a 36hz tune. i intend to build the entire box minus one side (leaving it to be held on by only screws) and change out the port as i test the subs volume. once i have things set ill glue on the final side. i would greatly appreciate it if someone would check my math and offer and criticism on what i have laid out here. thank you very much.

Scott we talked about you reconing a DD 2500 motor which has a 2.5" coil. Well i was woundering if you have any coils that will fit an Atomic AP/SPL gap? If so im going to send you an email with some more info. Just wanted to check with you before i picked up these other two motors. Corey

just wanting to know if you guys can or know if another company can. thanks!

hey guys, i would like to know what you think of this box, im a some what noob/mid level at box building SUB- ssd12 basic with maybe a flatwire option AMP- rocksford t500.1bdcd, the birthsheet on this amp say it does 810watts at 1 ohm, which is what i will be running it at. here is the box http://s1244.photobucket.com/albums/gg580/ott9311/?action=view&current=a1_zpsf9dcb1d5.jpg please give me any input u would have, i listen to alot of rap/hip hop so im tuning for 33hz i know im prob under powering the sub, but i thought in a ported box you could under power it by a LITTLE bit. based on my above state facts, should i make the box any smaller or bigger? more or less po…

im looking for a ported box for the trunk of a 95 caddy, 14"H 14"D 38"W is the max for the box. it's for a 12" ssd how long/big should i make the port to tune it around 33Hz's it also going to be powered by an alpine 650 watt amp.

im planning on making my own box for my btl. but im not really sure on the port at all. so here is my question im planning on making a box with about 4.5 ft3 of air 35.25L x 18W x 17H how big should i make the port if i want to tune it to 32hz? like the outside length and width, and the internal length of the port thanks if you have any suggestions ill gladly take them this might of been posted before but the search hasn't worked for a couple days now

I was told that I could check the sub with a dmm meter to see if its in good condition I got a 1.9 reading is this good, I think so just want to make sure? Its a 2 ohm dvc

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

Got 2-12" BTLs the old versions. Im trying to make up my mind on what to power them with between a AT-5000.1D or the AT-7000.1D. Its only going to be a daily blowthrough in a '97 Thunderbird. Which do u think I aught to go with? If I went with the 5K Id be saving needed space due to less batteries. If I went with the 7K its a $400 difference in price and Id have to get an extra rear battery on top of the ones I already plan to run.

i have a 15' Q. want a box that will get really loud. recamended size is 2.6- 4 cu ft. @ 28-33Hz. with 12- 16 sq. in. of port per cu ft. would a larger port be better than a smaller one?? i was thinking of doing 4 cu ft. @ 35 Hz. with a 6" x 10.5" port. how long would i need to make the port to tune at 35Hz??

I scored 2 15"q's of ebay for 405$ So im in the process of designing a new box for them. My box total after speaker and bracing displacement is 11.488cuft. So i need about 137-183 inches of port area. I was thinking a 9inx20in port 25.84 inches long for 30hz. That would leave me 8.798cuft after all displacement with 180 inches of port area. Does this sound good? If not what would you reccomend?

I'm looking for the best box designs for this kinda of subwoofer? I want sealed because I want clean cut bass and me and my buddy are going be building the box tomorrow and sealed is the easiest build for right know till summer time. So any one have the best box desgin for Fi 10 Q sealed and test on it or pictures would be great. thanks lata

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.

Can someone tell me if this port size is right for what I want. Box size is 12.91 cubes after subs and port displacement. the port size is 23hx7wx14.56d = 32Hz. Is this right? 2-18'' Q's will be used in this box. Looking for it to hit really hard and will this box hit loud and hard? the subs will see about 6.45 cubes each. Is this box good for the Q's to hit really hard in?ready to build today....

I ran 2 bl 18's off 2 sundown 1500d's for little over 2 years with no problems at all. Those bl's had cooling, flatwind, daily options. Now they offer to have a 4" coil for extra $50. This time I will be running either an aq or sundown 3500 on 2 18's. With the 3500d should I go ahead and get the 4" coil, Im pretty sure the 3" would be fine since I ran the others with no problems that long. thanks for suggestions

Alright i'm in need for some help designing a box for my 15Q. Its going in my Diamante. The largest outside specs for it are 36 wide, 24ish deep and 16 high. If anyone could help it would be greatly appreciated.

I want to build a box for an fi ssd 10. Should I go ported or sealed. I'm leaning towards ported. I could use some box design help and any suggestions. I'm waiting on my brz 2100 to show up until I order the sub but wana get going on box designs

does an one know the displacement of a fully loaded BTL the web site say .26cuft but thats not with the 3rd slug, just tring to get as close as i can so that way my port will be as tuned as possible, or is .26cuft close enough
