Would there be a difference between 2 12" SSD subs and 2 15" SSD subs getting the same power. Would there even be a big difference if the 15's got a little more power.

I am looking at either a US amps XT-2000D, a Concept CD2410, or a Massive audio P1500.1. Which one do you think would be the best to get? Or any other suggestions for around $400.

i want some subs that will hits hard and will be heard from a block away but also have good SQ. Will the SSD's do the job or do ineed to save up and get the BL's.

well i think im going to order an 18" Bl and was wondering what options i should get, i have a ed nine.1 (1200rms) but will probably be a lil more cuz its underated but anyway what options do i need for this type of application?

I was talkin to this installer today about various things, such as size limitations within vehicles. He said that there is barely a noticable difference between 2 15's and 4 15's, and at that only about 3dB's. Is this true? Doesn't seem to right for me, but I am a noob.

Let me first start off by thanking the guys at Fi. Scott, Shawn and Nick are awesome guys to deal with. I would have no problem recommending them to a friend or dealing with them myself again. They got back to me extremely quickly whenever I had questions. It just blows my mind that someone like Scott can work an eight hour day, then come home and continue to help his customers. On to the goods, I have a pair of DVC 1 ohm 12

What would be louder 2 12" SSD subs each getting 800RMS or a 1 15"BTL series sub getting 1800RMS.

First off, I could NOT be happier. Alot of bang for the buck, and that's what I needed from this sub. It sounds excelent, especially for being in a box thats 11.6 cubes. I set the amp to send the sub the full 1000 watts when the bass boost is all the way up. When I listen to music, I have the boost all the way down cause its still loud, but sounds perfectly in tune with the mids and highs. Whenever I get bored is when I crank it up, but personally my ears dont like the pressure all too much. This enclosure was intended for music with the tuning at 28-30 hz, and I never planned on competing, although I went to a db drag on the 15th. I entered and qualified with a 138, quit…

Alright so i've done a lot of measuremeants and i'm pretty sure i can easily fit in an BL 18. How well do they work in a box around 5.7 cubes before displacements. Also i need some help figuring port size. I'm going to have to have sub up but where should port be and size. Height is 17" to any obstruction, 36" width and about 28" long. Any ideas for box??? or should i just settle for a 15. Its going to have a US amps XT2000d on it and i'll get cooling. Thanks, Austin

Ok, here's the deal. I need a little more room for passengers in my truck so i've decided to down size to a 10" sub. These are my questions: 1) Will a 10" Q handle the power from a SAZ-1500D at 1ohm? or would a D1 wired at 2ohm be better? 2) Would there be a noticable difference going from a 12" to 10" sub? SQ wise that is. 3) What is an optimal sealed enclosure size, square footage wise, for a 10" Q? I want it to get loud but sound quality is my main objective. All I can think of for now. Need more info just ask. All help greatly appreciated. Chris.

Hi everyone, The Prototype BTL 12" w/ pole chamfer dual 2 ohm was purchased back in Nov 06. Wow it's been that long already! The enclosure I'm working with is the recommended 2 cuft tuned to 33Hz for a solid daily driver. The amp is currently the Fosgate Punch 800.2 wired at 4 ohm bridged which I have been waiting a long time to upgrade but haven't had the necessary funds. Everything is going into a 2004 Mustang. I just upgraded the wiring yesterday to 1/0 Kicker power wire. It was a tough fit on the thin trimming by the door but with a few modifications, I made sure it would get installed. My Head unit is a Pioneer DEH P780MP. Fi has been great to work with and they …

Ok i'm wanting to get 2 BTL 15's, i've got an MA Audio HK4000d for power(2000 watts to each 15) it will be mostly for daily driving, but i do go to 3 or 4 comps a month.. What options should/i need to get to get the best performance from these subs? thanks.

So the new BP optoin on the Q is spupposed to increase the power handling from 1000 watts to 1200 to 1500 watts correct? Does anybody have some pics yet? I can't wait to order mine, I just need to sell my old stuff first.

Show your pics

I have been researching amps and came across a Soundstream. Haven't heard much about them at all. Are they any good and could the 2000 easily push a fully loaded BTL daily with ease???

im about to get my 2 subs reconed to se/xxx's by the one and only Scott :-D then in a few months upgrade to 2 15" btl's. i have 700-800 for sub amps or amp what do you guys think i should get. the subs will be 2+2 coils a/b 200.1 or 400.1 or 2 bxi 2006's ?

I recently had a Hifonics BXi2006D, but I think that is blow up . So I am looking for a new amp. I am trying to keep the price around 500, but that doesnt look like its going to happen. I am just looking for some sugguestions. Thanks.

Im gonna put Four 12" subs in my car and only have .9-1.1 cubes ea sub and want the best and want it to hit really low and good in the midrange also. J

I will be pushing 4 15 BTL's in my truck and am not yet sure which to use. Either 4 Kicker 2500.1's or 2 RF4000's. Any ideas would be nice. Overall, the 4 kickers still only come out a little above the price of the 2 RF's if I buy local. any suggestions, or even another brand that would be better for a little cheaper......

okay this is what i have: altima 2005 2.5s stock electric system pionner HU DEH-P6800MP zx1000.1 amp 1 12" Fi Q box: 2.32 cuft ported tuned to 32hz first of all let me tell you that i was afraid that the amp wouldnt meet my expectations, but after hearing the woofer everything change, it really loud, i cant turn my stereo over 30 (in volume) because im afraid of the rear view mirrow falling off, tthe sub has great SQ it hits the lows really nice and i would recomend this sub for anyone that is looking for a LSQ system. http://www.youtube.com/watch?v=mpRGw40gxkU i will do a better review when i get more time with my system, but as far as right now im extreamlly satisfy.

This is my 12" BL d2 off a Nine.1 at 1 ohm. 1st part of the video is what it sounds like from inside my kitchen. Video is kinda dark...due to poor lighting, sorry for that. Ill try to get another one later with more light. Enjoy.

i know a lot of people has the btl because i hear everyone talking about those subs but i never see any scores, so if you have your numbers can you post them so i can get an idea on how good they are 1.sub size 2.amp

Post your setup and what you have been metered at. I have 2 12" D1 Copper Coils 1 hc 2000 1 saz-1500d 4 cu ft enclosure each chamber seeing about 2 cu ft So far I have been able to obtain a 140.6 with my 2 12" ssds but feel like I am lacking somewhere because I know she has more in her... anywho post those setups and scores.

i now have two JL 13w1s in a custom slot ported box running off a JL 250/1 Amp in the back seat of my cavalier this is just way to big for my car. I was wonder if i put a 15 BTL in a 4 cube box tuned to 34 in my tunk with a Hifonics 2000watt amp and a new yellow top would there be any diffrence in loudness. I love being herd from far away and i love shaking peoples cars when im around! lol tipcal teenager. My JLs do a decent job but i need MORE! will there be any diffrence?

will two btl 18's last a while ran off two warriors (4000 watts daily)
