What si the Zmax of the SSD 15.. Also if you can tell me other Specs that are not listed on the site.. that i will need for designing let me know thanks

Hey im new to the forum and new to Fi. I have been looking around to put a new system in my car and decided on Fi. I plan on purchasing 2 10' SSD with the copper coil and i was wondering if yall had any suggestions on an amp. I was looking at A planet audio RXD-1400 that puts out about 1400 rms and 1900 peak but i wasnt sure. Any help would be great thanks.

I'm about to purchase one to go with my JBL 1200.1 Plan is to make a sealed enclosure. I have up to 3 cubes to work with and I see that Fi recommends 2-2.6 What size should I make it? I'm looking for deep and tight bass. I love low lows and when the sub just slams. Other question is weight. How much does a Q15 weigh? Last question is can I run the full 1200 watts to the Q15? thank you

Box is 13.5cuft Tune to 32hz After subs just under 13cuft Subs are in a common chamber one large vent this is a slot port what do you think about VENT inside area height 5 in Width 39 in depth 15.5 in This vent will be taking up 2cuft over all this numbers were made with carstereo.com calculator is this going to work good or do i need to rethink it again WILL TAKE ANY INFO

I've got a Q15 with BP Power in 4 cubes @ 32Hz with 58.5 sq. inches of port powered by a Sundown Audio SAE-1000D in my grand marquis, and I want to try a new enclosure. This is a trunk car and the seats do not fold down. What were your favorite enclosure specs for the Q15?

would a kicker zx 2500.1 be to much power for a loaded fi bl 18 daily?

I have a BTL 15 dual mag hooked up 1 ohm mono to Sundown 3000. When I really want to get on it the sub sounds like it is bottoming out. When I had it hooked up 2 ohms it did not do this. Also I have yet to blow my 100 amp fuse. Have 300 amp fuse standing buy but with the popping I have to keep the sound down enough so I don't know if I'll ever blow this 100A fuse. Doesn't sound like tinsel slap to me. Box is tuned to 35hz and is almost 4cf. Thanks in advance Ronrico Joe

ok guys i have a RF BD1500, birthsheet 1740 @1ohm, would 2 12" Q's or 1 15" BL be louder?? or is it possible for that to move a BTL a sufficient amount?? and also could you tell me what options to go with please and finally if i get a duel 1 ohm, does that mean the amp sees it at .5 or 1 ohm? and the duel 2 at 1 or 2?

Question What is the highest and lowest tuning that you all know of for the differnet series of the Fi lineup? AA would also be considered. Personally I would be most concerened with 18s and 15s I currently have 1 15" BTL dual mag in 3.8CF and tuned to 35hz Many people including myself (surprise) are really impressed by the output of this sub/enclosure combo I however have realised that (to know surprise) the cabinet is not capable of playing the lowest notes. Really needing more airspace for lower simpler tuning abilities, the box is great for "most people" and say a "rocker" type listener. Now since I myself am a rocker, Staind, Linkin Park, Korn, come to mind mo…

I have made up plans for a 6cu ft box, after port and displacement. The port would be 4" Wide and tuned about in between 33 and 34hz. If i made the port 5" wide, it would take the box all the way down to 5.1 cu ft or so to be tuned to 34. The port would be 21.5 in tall. It just seems to me that 4" is small, but then again thats a lot of box volume to take up. I'm really hoping i'm just more worried than i should be about port size, and the 6 cu ft will work out. Any suggestions?

So I have a buddy that

Anyone know the "Le" parameter of the Q18 dual 2 ohm sub? Thanks for any help.

does an one know the displacement of a fully loaded BTL the web site say .26cuft but thats not with the 3rd slug, just tring to get as close as i can so that way my port will be as tuned as possible, or is .26cuft close enough

I was told that I could check the sub with a dmm meter to see if its in good condition I got a 1.9 reading is this good, I think so just want to make sure? Its a 2 ohm dvc

alright for about 2 months now i have been breakin in my 15 inch bls...... so can i feed them more power now?? or should i stay the same?

Hey guys, I am new to these forums and new to Fi. What i was looking at over the past 2 weeks is that in order to power these subs, you need to require a) cash b) automotive parts c) More parts Lets just stick with b), Now i was looking at some of the earlier posts, alot of them were for the Iraggi Alternators. I myself have a 95 Honda accord. I Like it. I obviously need a new alternator if i am going to get myself 2 Fi subs. Everyone is going for the Iraggi Alternators. I myself can't find one anywheres on the internet. I checked eBay and all they have is 60amp. I am pretty sure 60 amp wont compare to a 2500w amp. So i came to the professionals, you guys, for some ad…

I hope this is posted in right place.... Two questions: 1.) What is the RMS and peak wattage for a single 12" BL with the dual2, flatwind, daily and pchamfer options? The reason I am asking is because I seen on Fi 's site that it says 1000w/rms, but everyone is highly reccomending the sundown 1500d (which i am about to get.) So, why is that so if it is only rated for 1000watts? Does adding those options bring it up? I had a new custom box built by Sound Advice here in florida and the guy who was instlling it says to me that I will not notice too much of a difference in swithcing from a RF Punch 1000w/rms amp to a 1500 watt/rms amp ( in this case to the sundown 1500d)…

I'm getting absolutly no sound out of my sub it was working fine for about 10 minutes earlier and than i unhooked it so I could set the gain correctly with a dmm and after I hooked it back up I got nothing from the sub The first time I hooked it up at had it at 1/4 gain up so I'm sure it was not clipping and I only played it on low volumes, I also didnt smell any burning So could could sub be blown? Dvc 2 ohm wires parallel to 1 ohm off kx1200

I'm kind of limited in space but here are the maximum external dimensions 34"W 18"D 14.5"H Sub is Fi BTL dual Mag. One out of Shawn Fleming's van from 2007 Dytna SBNs if anyone is familiar w/what he had. I only know that tit is a dual mag and will definately play music. Amp Sundown 3K Not looking for SPL nor just the LOWZ Sub up port back (I will do both in center although woofer mounted to one side makes more since to me) but hey what do I know I can't even measure CF So I guess basically can anyone figure out how much Cf my box will be minimal bracing (just 3 2x2s) 2 13"L 1 32.5"L and dimensions on a port WxH=port but how deep to adjust the tuning? Would like …

is it ok to trace around the inner black gasket ring that comes with the subwoofer to get the size for the cut out hole?

2 18in btl's fully loaded 12 cuft tune 34hz Port wide 18.5 in height 5 in lenth 10 in That is 185 sq in 12 x 15.42 = 185.04 right? thanks

Yes i read the sticky at the top of the page, but i just wanted to see what people thought. I haven't bought anything yet, but what about a hifonics bxi2006d (yeah i know its not sundown or anything), at 1ohm (1800-1900 watts im guessing?), on a bl 18 with p chamfer and flatwind? would that be enough to handle 1800 rms? I know i could turn the amp down, but i wanted some input.

Just got my 15" BL two days ago "THNX Scott!" Just wondering your guys opinion on this box design... does everything checkout? I'm iffy about the 3.8ft^3 should i cut it back to 3.5^3 http://www.subwoofertools.com/forum/ported...s=34.5&CE=0

Just got my 18" Q w/BP in the mail yesterday. (thx scott). Next week is spring break and I need a box design for the back of a 97 blazer. I have about 8 cubes to work with. Accordman from steavemeadeforums told me to go 6.3 ft^3 and 90 in^3 of port, which results in a 32-33 hz tuning. I have never worked with 18's before, and I've heard certain boxes for 18" Q's can really restrict their output. I only have about 1000 watts RMS from a bxi1206d to work with for now, but plan on upgrading to 1400watts rms. My goal is to make a well balanced box. Not pure SPL or superlow tuning for SQ. I just want to get the most, good sounding output from the sub. And i'm a broke a…

what do i need to change on my cut list to have my box tune to 32hz? Tthis box is tune for 28 hz
