What would be the best amps for 4 BTL 15"s

And I can not wait to see them.

I wanna get loud...I wanna sound good. Im on a little bit of a space restraint on my box. So i plan to go 2.4 cu ft. tuned to 32hz more info later

i placed an order last night but the paypal said some funny stuff i was wondering if i could get a number to call fi at?????

hey whats up fellow bassheads, i had bought my had a 12" re seX for christmas and he has loved it in a sealed box. Ok so he needed to use my car the other day for a trip so he let me use his truck for work. So i was checking out his settings on his amp to see if they are where they should be and the bass boost was on a little bit so i turned it off. ok so i went back to check out how the sub was doing and i gently pushed down on the cone to see how stiff it still was. when i pushed down easily i felt like a scrubbing or kind of a gringing against something?? I have no idea what this could be or could it be blown? i thought it was not normal but then again it doesnt sound …

Thanks a million Scott for helping me get my SX recone kit. it took me a while but i finally got the order in and finally received the recone kit for this sub that's been sitting around for over a year. the packaging was EXCELLENT. nothing on the box shifted around or got banged up. well in the order i completely forgot to mention that i need CA Glue. though buying a recone kit i would have assumed that you send out CA glue with the kit, but anyways, How about can i get some CA Glue to set this sub up? if i have to buy it since the order was completed please let me know.

i purchased an SSD15 for my niece's car back in October i believe. built a nice ported enclosure around 3.5 cu/ft. i also installed a Kolossus Fleks 0 Gauge amp kit to an ASA800.2 powerbass amp. power at the amp was at 13.6 to 13.8 at full tilt. i also set the gain with a volt meter and tinkered with it by ear. i am no expert by any means, but i did a lot of reading on the subject of install to avoid any kind of clipping. anyways, i told her not to mess with the setting on the head unit. well, played around with her system several months later to find all the settings were jacked up, loud button on, bass boosted in the eq. changed anything back to where i had the…

my buddy is wanting eather a 15in fi bl or and fi Q he can't decide which on will hit harder.

Just wanted to say that Nicks CS is very good. I shot him 2 emails yesterday asking about recones, and he got back to me within an hour, and has been answering all my questions. So......... GJ NICK!!!

I was thinking.... Right now I have a 15" BL with an RF T10001BD amp, its loud, very loud. I want a more sensible setup but attempt to keep the same sub output, I don't think its possible. I want small box, small amp, and still be able to do 140s. I know thats not possible. I just want to reclaim my trunk space back and my spare tire and jack!!! With that huge box in my tC there is no more trunk space!!!! Now I am getting kinda tired of hauling around a 100lbs box... Ok I'm done ranting....you may return to your regularly schedule program.

I am just looking for a few different color FI ball caps.

After watching some youtube videos of some fi's I heard a lot about stock electronics and what not. I am getting a 15" Bl and will power it with a Hifonics 1200 or 1600, and am wondering what "electronics" i will need so that I don't wreck my system/car.

Just wanted to say thanks to scoot and fi for helping me get some materials i needed to get my sub up and running for a usaci competition today. Got 3rd place with a 146.9 but more importantly had a blast.

hi its me again, i currently have a bl15 great sub, Ive seen people seem to like more the 18 inch subs better than 15" are 18 that much better, i see they need a big box but would the output be that much better if yes what percentage increase do you guys think i can get with a 18". Now my other question how can i make a box for one that is going to be in my caddy devilles trunk i cant go higher than 19 inches tall for the box and i dont think i would make it becuase the sub is 18" plus box material .75, so can i make a box facing up and port facing to the back of the trunk?? would that sound good in a car?? thanks again and comments are apreciated.

So, I'm going to Vegas for a vacation from the 10th-18th Sept. Any chance for me to see the factory? Seriously.

I've already seen the tracking information on UPS about the BTL18 and BTL15 that my Aunt ordered for me. I was kinda worried when I saw the shipping weight on both packages. One package weighed at 69lbs which i assumed was the BTL18, while the other weighed in at 55lbs. I was expecting the BTL18 to have a 72lb weight considering that its fully loaded and packaged with wood reinforcements as to having wood reinforcement is very important because im gonna have it shipped to the Philippines together with the BTL15. Im just too concerned about their weight because I was informed that the BTL18 should weigh around 72lbs while the BTL15 should weigh around 69lbs. and im startin…

You all might be wondering why I would post this in the Fi section, so i'll just let the pictures do the talking: So far, all panels have been cut and port areas have been painted. The plexi front panel will have a Fisher Custom logo CNC machined on it as well. To follow the build over on CA.com: http://www.caraudio.com/forum/showthread.php?t=284556

Hey guys! So I just bought a brand new 2010 cobalt Lt 2 door and I am lookin to throw a 12" BTL in it! One problem is the trunk is Small!!!! My old sub box wont even fit and its not as beefy as an Fi it was an Orion hcca 10" But I really want this sub so I was thinking of getting the Fi built into the trunk Like Fiber glass or something. You guys are really helpful so I was wondering does this seem like a good idea to you? any other adivce perhaps? I would give you the trunk specs but its drark right now I can get them tomorrow. Has anybody tried na Fi in a custome trunk? thanks for any help!

Hey guys, ok so I bought a 12 ssd with the copper coil option and Im going to be running it off the Kicker zx1000.1 amp im putting it in a 2008 nissan frontier extended cab and i was wondering what you guys think would be the best box dimensions for both ported and sealed enclosures I am building the box my self and i just wanted the deepest lowest bass with the SQ Thanks

I have not really got a direct answer yet, so figured I would post here. Would 2x12" Q's in a sealed enclosure move more air than a 12BTL ported? I prefer low bass ~30Hz. So far, I like how deep my 12BTL gets, I don't want to lose any of that. I haven't heard many systems, so I need to ask alot of questions sometimes..lol

I was wondering how a Fi Q12" sub would perform in a 4.2ft^3 enclosure tuned at 21hz? I would be giving 2 of them each in their own 4.2ft^3 enclosures 1000 watts each from a crown XLS2500 amplifier. Would this perform well or are their better sub options? They would have a subsonic filter at 21hz and then a LP at 80hz. My surround speakers can easily keep up with almost any sub combination out there considering I spent about $4,000 on DIY towers and DIY center channel alone... I hope this being a car audio forum it doesnt bother you guys me asking about home audio... I know a lot of guys using car subs for home theatre.

i am running (2) 15"D2 Btl's in 6 cub. ft. @ 32hz right now. the amp i am using is a zx2500.1. what is a safe or optimal freq. to turn the amp to? is this something that is done by listening or is there a general rule of thumb. i am just noticing that the higher notes in almost all the songs i listen to, are almost not even audible. the lower notes are def there but what would correct this "problem?"

I used to have all three of these numbers but I lost my old phone. Please don't put these numbers on here publically send them to my email at [email protected] thanks guys I appreciate the help.
