true....but i have a good grasp of car audio subs amps ect....they are in a big box but it is within the bl 12 specs....and i try to run clean power no clipping...

yes true....but more or less...i was looking to see other bl 12 owners and what the max they have put on them is.... so far they seem to be runing fine on a crescendo 3k.....but i have my gain set to 50% and the amp could give so much more...i'd llike to see the bl's take it im not going to lie... but im not willing to risk them....until i know if they can take the amp on full tilt....i mean i did pay for the options to they would take more power....so the rms should be above 1000 right???

im not 100% on this.....but i think at least the bl sub comes with a plug under a sticker on the back of the magnet...im not sure if im right...and or if q's are the same...but if they are...it could be the plug...but i dont see how...are you sure it came from the sub and not the box....maybe you left it in or maybe....JFK....u.f.o's.....rouge wave......HAARP...ect ect

one billion!!!!....puts pinky to lip******

lol i sold my old subs to get fi's went 3 weeks with no bass.........even that felt like a year lol

nice...what HU is that i got the eclipse avn-7000 myself..

i have 2 fi bl 12's running on a crescendo audio 3k and the fi's are getting real warm...not hot.....just real warm....and i was wondering if this was normal?? also would a crescendo 3k be over powering them?.... im hitting around 140 db. and it sounds great in a 5 cft box tuned at 32 hz...its just getting warm and it worries me...

lol nice...when you say you ran them hard....how many watts are we talking about?? 3000+ 4000+???

true that........i just recently seen two memphis mojo 12's hit 145.5 on a memphis 3000 watts amp.....and i really wanted to see if my bl's could match this in my current setup but i punked out....would really like to see not only what the subs can do but also the crescendo audio 3k.....i really want to see if its as good as the other zenon amps...i may never know lol You will be fine as long as you know how hard and far you can push them. Its better to be a nancy boy then a damaged sub boy, but you should be fine as long as you know your subs limits.

i got 2 of these also....great subs.....

i have 2 bl's in my trunk..dunno if this helps...but look at building a multi part box outside of the trunk and then fitting and sealing it together inside of the trunk...its kind of a one way thing...but it worked for me...worked great

right now im n0t taking them much past 140 db. in this box....im not sure what two fully loaded bl's should peak out to in idle conditions...but i just keep my head unit sub level and bass boost on the amp at 0....turning them up seems like a bad idea lol...maybe i am being a lil nancy boy about it but im at least a small bit afraid to damage them.. You will be fine as long as you know how hard and far you can push them.

yes they are new 2010 bl's less about 1 month old but i just got the amp...and also they are fully loaded

also about the crescendo audio 3k...does anyone think this amp is too much for two fi bl 12?? or should they be able to take it?

you need to build a box to fi bl specs for the bl.....i had to make a few boxes to get my bl's to hit the way i wanted.....ended up at 5 cft 15 inchs of port per tuned at 32 hz...loving it also running off a crescendo audio 3k amp

i was thinking is was normal....they did cool down quick...10 minutes with the car off and they are cold again

yea about and hour at a time on most drives... but i can get it alot louder even in this box....i use no bass boost ans keep the sub level of the head unit at 0 and also only run 50% gain...its what i like to call a easy 140 db. i say that just to be safe...i have no idea what its max is yet..i will be finding in about 2 weeks when i go in for my next term lab...but im happy with the box it really slaps good in my car...moves a good deal of air..

thank you...perfect...i just did not want to act with haste...but this is what i figured..

i just got my fi bl 12's in the mail and unpacked...in the screw holes of the sub surround there seems to be foam or some type of material blocking the screws path to the box... should i just force the screws through or is there a mistake in the build of my subs???

hello this is my first post here..i just got 2 fi bl 12's they are not here yet...but does anyone know what kind of db i can expect from these??

nice

i know can hit 139.7 tl with my first install.....it was all optidrive....it was ok but cheap...im trying to break 149 with this one

good show thats the type of stuff i was looking for

yes true...there are so many things that come into play.....well i am running them at 2400rms 1 ohm 1200rms per sub..i have the big 3 upgrade done a 0ga setup and 2 kinetiks khc1400s...still a stock alt..and my box is dual 12" single middle vent box tuned at 33hz with 1.8 ft per sub...i still need to build another box.... but what im asking for is more or less a range of what these can do with the right or wrong setup...or if anyone else has two of them what they are doing db wise..
