What is the Fi BL 15 able to hit on the spl meter.. Options are p chamber, and daily running off a rockford p 1000-1bd(1382rms @ 1ohm)

hey everybody im new to the forum but im really looking to support FI and need some help .. i plan on buying 2 12 inch subwoofers but im not sure if i should go with 2 Q's or 2 BL's .. i would get dual 1 ohm on each so i could have a final load of 1 ohm. i plan on wiring them to a Rockford Fosgate Punch P1000. my question is wich subs would be better for a solid hard hitting low , something that will take your breath away almost. i aprreciate all opinions

Here ya go guys... enjoy! BTW, I hope not to catch any hell from running the 8 guage speaker wires through the port

Im fixin to get 2 ssd 12's stock and a **** hellfire 1000.1 amp what kind of box do you think i should get to give me the most bass travel

I think you guys at FI need more descriptive information on each speaker. On how each driver reacts to different enclosures and how each driver compares to another. If i was a new customer coming to your site i wouldnt know which woofer would suite my needs just with the information provided on the website. Im not trying to bash you guys in any way. Just more info would be good. Thanks James

Well Im about to pull the trigger on the 15'' Fi Q. It will be in a Sealed box ill be putting about 900w give or take to it. I wanted to know will this sub be louder/ hit harder than a 12'' type x? I know its not a SPL sub but i just wanted to see because i hear it hits pretty clean.. Thanks

i plan on ordering 2 12" Q's w/ bp power option but am not sure whether i would want dual 1 or dual 2 ohms? i will be running them off of a sundown 2000. also what size speaker wire would i want to run for the subs? thanks in advance.

2 fully loaded btl 15's -or- 2 bl 18's please help !

I have a 2006 F-150 super crew. I'm planning in running 10000 rms in 4 subs. I plan to install them in the bed of the truck but I dont know what size is better for a blow through. I would like to have 4 18'' but I dont know if they would have the space that they would need.

Was pulling my bl to get pics of it and noticed a hairline crack in the top slug that goes about halfway around, il get pics in about 30 mins. How could this have happened? It was fine when i put it in the enclosure.

I have an 18" ported box ~6ft tuned to 32hz. I have 1200 watts on tap not upgrading on that end, which 18" will fit my set up better? I luv my bass deep and loud but really looking for an overall good sounding speaker to play with rap, r&b

Does the older style Fi Q have push terminals or standard allen wrench terminals? I know they have a different motor style than the new ones just wondering about the terminals.

hi i just bought my fi sub yesterday and took the dvc 2 ohm and was wondering if a hifonics brutus bxi2010d would do the job or should i go with a more powerful amp like the bxi 2408d or simply another brand.. please let me know whats your opinion on that issue

hi i purchased my sub couple months ago its a Q d1, im runnin it on a mtx te1501d 1000rms in a 2.5cu box at 32hz at 2 ohm and i have all the options on the sub and its used daily, few days ago i noticed it wasnt bumping as hard still worked then all the sudden on my drive home today smelled somethin smoking and my sub went out , pulled everything apart wasnt the amp pulled the sub and soon as i pulled it out the box a bunch of smoke, the cone was cracked and broke away when i touched it, do i need a recone or what i thought runnin it at the 2ohm would set me staright for daily use didnt think it would abuse it too much, am i wrong, pls help thank you

Hi, I am from india and i am keen to order the FI subs for my car after seeing so many satisfied customers and so many videos of good things about them. I want to install them in Chevrolet optra (4 door) aka Lacetti in USA....My current setup has HU--Alpine 9887 Compos :-- rainbow SLC 265.65 NG Amp for Compos : -Audison Srx 4 Sub :- Alpine Type-R 1222d (12") 2no.s in a sealed box 1.35 cu. feet for each Mono amp :- Alpine MRD M1000 Power acoustik 3.0 F capacitor Audison and Directed Audio RCA, power cables, Audison ground and distribution block I have touched 140 DB on the windscreen easily in my sedan with this setup now its time to upgrade wherein i have multiple choices…

Got my setup running yesterday and it hits the top end of the spectrum with ease I am finding the lows are a little lacking ? (16cuft wall, tuned to 30hz) They are brand new subs and the suspension is super stiff, will playing them over time make the lows better ? Reason bein my previous Re Mx install played the lows very well straight away.

Its on the fi website. What are they getting at?

Do I really need the Hixmcoil option on a 15" Btl? It states that if u use the sub for daily bumping then Fi suggest that option. But if u must have it for daily bumping then should the Hixmcoil be standard/stock instead of a option(If you choose daily option)?
