So, I am lookin for an amp to run 2 10" bls and am not entirely sure what to go with, would something like a RF4000.1 be good or should I stay with a 3k watt amp....in which case, what is a good 3k watt amp

so how do you "break in" a ne sub? i relly wanna know thanks in advance

The rubber lip around the edge of sub is not aligned properly to the holes in the metal. I was just curious if it would damage the sub for me to peel the lip off and align it correctly. The only reason I would do this is so the people that install the sub dont slip up and just drill right through the metal instead of the holes designated. Thanks.

Leaving now and going out of town for the weekend, email me if you have questions as i may have data service with my cell phone...other then that i will be back here Sunday night. Thanks! -Nick

i blew a voice coil in my 15" btl, how much are recones and is reconing it difficult?

Sorry everyone for not getting to spend much time on here this past week. We have been excessively busy at the shop, but I have simply hit the "not enough hours in the day" thing recently. Between Fi, Ascendant, and several new OEM projects I have been swamped. I finished up a some design and testing on the OEM front this week and will clear up one more sub system by the end of the weekend (or at least the latest iteration of it). Im hoping to be back on here in full force starting Monday next week. In the meantime... there have been a few things I wanted to do this month that I simply havent had the time too... Since this is our 1 year anniversary for Fi, I wanted to…

Hi, I'm looking at purchasing a SSD10 (Dual 2) but I don't quite understand the other three configuration options, flatwind coil, copper coil, and BP Power. Could someone explain what each of these mean/are and what their benefits are? Thanks! Adam

Hey guys! Here are a few vids of my Q 15's. The first 2 are vids with my first box which was 7.2 CuFt after all displacement tuned to 32 Hz. That box fell apart cause the guy who built it didnt use any kind of adhesive in the joints...only screws. You can actually hear the rattling from the box...it sounded horrible. The second 2 are with new box which is 8CuFt, tuned to 30hz with 120 SqIn of port. Enjoy! The vids just dont do these justice. This is by far the loudest and best sounding setup I've ever had. If you look in the last vid, and look by the sunroof, you can kinda see better how much the roof flexes. Was shot with a phone so its not the best but you will…

I hate to ask this question, but I need to for my own clarification. I have been seeing a lot of IB setups lately, both on this forum and also in magazines. I listen to almost all heavy rap. Would an IB be totally out of the question due to all the extreme bass? SHould I just stay with my 2 10" BL's that I am planning? I like the look of them and the fact they take up so little room, I just have never seen one perform and dont know how they stand. Sorry for any inconviences, but it would be nice to know.

well i have seen alot of ppl asking for some weird recones lol so i thought id throw mine in too CAN YOU RECONE THIS JL W6 18" WITH FI PARTS???????????

but just in case, the top plate on the OZ 12 is 0.5" thick. give me a call so i can give you my debit number thanks!!

As the title suggest, can I resell or trade back the 15" SSD I have that is still in great shape for some credit for purchase of a "bigger" and "badder" sub? Looking for 15" BL with a few options and different ohm load. Advice? Input? PMs? Please let me know! Just thought I would post here for Nick or Scott or Shawn to provide input, or tell me to take it to PM if necessary. Bob

so does this sound better then tryin to fit a 18 in my trunk.. run a btl in a 3 plus cube box.. http://www.reaudio.com/speaker_box/LPort_Box_Calc.html http://subwoofertools.com/forum/ported-box...mp;Fs=&CE=0 if thats better which amp should i get.. at least the rms right..

Hey guys, i have a question about box size for the BL. I have an 18" BL fully loaded and its going to be going into the trunk of a 1995 Honda Accord Sedan. Currently, the box is mounted horizontally because I needed to do that to get the minimum size of 5 cu ft. However, after taking up the entire trunk in my car and having the subwooferer horizontal. I'm wondering what the minimum size you guys could see? I'm hoping to still keep it ported somewhat low...at around 32hz or so. I realize this goes against all of hoffman's Iron Law and what not, but what are your guys best ideas for this? I'll sum it up for you: Current Box: Subwoofer mounted horizontal 5 cu ft box @ 29Hz…

well last night i was going to work and i saw 1 blown infinity kappa perfect 12 so at first i walked by it....then an idea popped in my head hmm maybe i can send it to scott and if he's able 2....recone it.... so i picked it up and as im carrying it( it weighs no more than 20lbs) i start thinking some more....wat if i can get it reconed to an 18..if not i will settle for a 15inch recone so i start thinking of names like the fi perfect 18 or 15, or the fi kappa 18 or 15...so my question is can fi recone the kappa perfect 12? i really hope it can be done this is wat the kappas look like.. http://www.caraudio.com/forum/showthread.php?t=259792 .this is not my thread i just…

ok guys i need to get this reconed to a 12" please pm me info and pricing if you can. i can ship it out either thursday or friday. i also have the owners manual in pdf if that will help. thanks!!

Hey everyone. I am new to not only this forum but to FI as well. I have always had "eh" subs that are sold in my area. I currently have 2 10" RF T1's in a 3 cu ft enclosure....I am lookin to upgrade to something louder and better and am not sure of which sub to go with. I listen to 75% heavy rap, 10% techno, and 15% heavy metal. I like SPL mostly, but want to retain some SQ. Are the Q's or BL's a better replacment for what I have?

okay on the fully loaded 18 inch btl what would be: peak to peak xmax rms power handling weight and what would be a good amp to run four of them or amps. i was lookin at 2 jbl crown amps the 8k watt ones @4 ohms would that be good. or should i do one per sub. well what would the experts do. i listen to rap and thats what will be played loud and long. so what amps would you put on them-brand,series,and wattage

Hey guys, I have a question about horizontal mounting a subwoofer. I've read various articles on it, looked at the sag factor tech page from adire, and etc... still, i've heard some convincing things about it still not being good. Here's my question for you: I have an 18" BL full loaded and its horizontally mounted. I ran the sag factor equation from adire and it meets the "criteria" of mounting horizontal. however, iv'e heard also that with gravity...it doesnt matter because gravity pulls down on it more and therefore i get more distortion, etc. whats the low down on this? Am i in some bad shape with having my sub horizontal? normally I mount my subs in the typical, firi…

I'm back....and my subs are still kickn ass. great product Scott.

http://www.caraudio.com/forum/showthread.php?t=260162 sorry for the link, but i had a problem trying to upload pic on here. check em out and tell me what ya think...!

What is it?

So.....I just installed the 4 Q15's in a sealed enclosure (8.6ft^3 after displacement) running on a IA 40.1. The car is a '07 Dodge Magnum, a 140amp Alt, and a 2nd NSB90 Battery. The meter was an AC, but it was recently calibrated and actually metering about 3 db lower then the other one I was previously metered on...(not that that reallly means anything) anyways, I hit 163.5db outlaw and 162.1db legal. I am competing tomorrow on another AC, and I'll let you know how I score there.

First the system: Right now I plan on doing 2 12's ported or 2 10's ported, Q's of course. 2k watts total. I will be running lots of mids and highs for "look" purposes as I am hoping to compete in shows, so I imagine around 1k watts, depending on stuff. I have a 160 amp alt and the stock battery is a 730 ampere battery. I already plan on doing big 3. I will probably throw in an extra battery as well. Will I need a bigger alt or will a 160 amp alt work? I know it brings a lot of other factors in. My amps are more than likely gonna be RF amps cause I can get a little deal on them. Any other suggestions or ideas to ensure I have adequate power would be great.…
