i have a guy that wants me to do a wall install in a 2004 sunfirefor 2 btl 15's or 18's. im going to have the wall on the smaller side so it can take a little more power but do you guys think 2 btl's can take a xx-maxximus (last years) for everyday use??? or would he be better off with 2 xxv-Colossus (new ones)??

I am toying with the idea of putting 2 12" SSDs in a ported box. My original plan was to seal them, but I don't know what kind of output I would get. Could someone help me design a ported box for these subs? I am totally new to ported boxes so I don't know where to start. I'd like to maintain as much SQ as possible and gain as much output as possible. Dimension wise, my trunk could accomodate a box 39" across and 17" high. Depth is negotiable, depending on the size of box needed. Thanks in advance for the help.

What can a SSD take on a burp which is normally 3 secs at most... I am looking to run a pair of Saz-1500d's strapped on my ssds and would like to know how many watts can they take on a burp.... I was thinking probably 1600 watts per sub but would like to know before hand..

All of my subs I own have the positive terminal on the left and negative on the right. Whether they be single or dual they are always in this fashion. I ordered a 15 sexxx recone for a se and a claw basket. I also ordered new terminals and wanted to make sure that I'm not going to install them incorrectly. My glue should be here in a day or so(I hope) and would like to start when it arrives. Thanks CJ

I have a 12" BTL with pole chamfer and my Memphis MCD2500 amp is coming in soon. I want to get everything ready so when the amp arrives I can install it right away. This is my mustang 2004 stock electrical: 130-amp. heavy-duty alternator 540 CCA heavy-duty battery Battery amp hours (58Ah) Battery-rundown protection I will be doing the big 3 wire upgrade with 1/0 gauge wire from batt to alt to ground. Besides that, what else should I invest in? I'm trying to keep it as budget as possible. Thanks. PS> This is my daily driver.

I will be running 2-18'' BTL's off of 2-MTX TE4001D's. I would like to know if this power setup is good for what I need to run my amps. Yollew top for the starter with a 200 amp alternator, 200 amp isolator, and 2 yellow tops in the rear for the sub amps. How would I wire the 2 yellow tops in the rear. + to + and - to - ? Ground each battery or only 1? Any help with this would be great and where and what battery,alternator,or isolator I should use? And what is the Big 3? Thanks Fi buddies...

Should the ports be on the same side as sub is on or not? I want my BTL's to fire up and the ports to fire up to. Does it matter where the port is on the box? Would it hit harder with the subs and port towards the back of my excursion? Thanks...

I have a 15" Loaded BTL that is in 4cubes. The box is .75 MDF. I will rebuild the box, should I doublewall anything other than the front baffle? I will probably resin the inside of the box, as well as brace it at several places.

Hey, this is my first post here at the SSA forum (oh whoopee ).... My question (YES, QUESTION!) concerns the tuning and enclosure sizing for the Fi Q18 D2! Firstly, I'm not too sure about the relationship between enclosure volume and tuning frequency. I did see the enclosure sticky, but am tuning differently than the sticky shows and am also not sure if the size stays the same for all tunings or not...I'm thinking it changes. I plan to tune to 16hz and wondered if 30ft

Hello. I have a 1999 Dodge Ram 1500 regular cab, and I want a "system". I have figured up that I have about 1.7-1.8 cubes of space behind the seat. I was originally wanting 2 12's, but I would still like to have the massive amount of storage space that Dodges have. So I was just wonding if I could fit an SSD 15 behind my passenger seat. The top of the box will be 6.5" deep, and the bottom will be 10.5" deep. The reason for going with a 15 instead of a 12, is just for the coolness factor of saying, "Yeah, I've got a 15". Thanks for any responces!!!

i have 2 10" Q's sealed, when i installed them i set the amp, after a few days i noticed they could take more (with out hearing a pop sound) so i adjusted the amp higher, i have done this twice now........ just want to make sure this is normal.

ok this is what's up I have an mmats d3500.5 I can buy 2 more or 3 massive p3000.1, already got 3 kenetik 2400's to add to the 2 1800's under the hood. I plan on putting the 3 15's in a fiberglass wall like the old JL audio 3 10 set up approx. 7-8 cuft per sub, so what amps would you guys suggest. Oh getting 3 massive's or 2 more mmats would be about $100 doller dif.

Will 2-18'' BTL's be happy with 2000 watts per sub? And will they play with 2000 watts each or do I need to put 4000 watts per sub? Need to smoke 2-13" w7's. Can 2000 watts per sub do it???

If one does decide to get this option does this by any means help increase the subs BL and if so do you guys have a estimated number...

Hey i just bought a 15" bl. i was looking around and everyone said a 4cubic box would do but anyone have any cut outs or exact directions. im not sure what i should tune the box to? hertz?? anyone have any suggestions!

Hey just wondering how (2) FI 12" Q's and (2) kicker 1000.1 will sound in a 3cuft total sealed box will sound? Thanks, John

Alright i'm in need for some help designing a box for my 15Q. Its going in my Diamante. The largest outside specs for it are 36 wide, 24ish deep and 16 high. If anyone could help it would be greatly appreciated.

Hey I was talking to Scott about reconing my tc9. he said he could, but i think he has been busy lately so i'll post this here lol. I have the address still from and earlier recone i sent in, can i just send the sub in with a little note stating what i want with my contact info?? or would there be something else that i need??

Im going to get 2 12" SSD's if i want to wire them to a 1 ohm load should i get the dual 1 or dual 2 ohm. subs.

i have 2 15"se/xxx's i wanted to know how much power should i throw at them also what do you guys think for a box. im looking for a loud DD. do you think of 9 cubes before sub and port displacment and 135" of port tuned to 35hz's

Scott / Anyone I had emailed Scott about this but I'll post here. Basically my questions is as below. I would like to seek help on my Q15 enclosure. I had builded a 3.65 cu.ft @ 34hz for the Q15. My specs and measurement as follows: Net Volume: 3.65 cubic feet Tuning Frequency: 34 Hz Port Width: 5.25 inches Port Area: 86.625 Square Inches Port Length: 47.5 inches External Dimensions: 34 wide x 18 tall x 22.75 deep Now, after installing and basically setting the amp crossover, subsonic filter and gains I found that the bass was muddy at times and lacked the lows. So I checked my amp setting even using scope just to make sure it does not clipped or distort. After listening…

I just bought a 15" FI-Q and now I am debating between amps. I looked at a high end: memphis mcd1000, Rockford Fosgate Power T10001bd, Low end: Hifonics BX1206D, Memphis PRD 1000.1. Any suggestions for an amp..or any listed that I should go with? Secondly, I am unsure if I should go ported with a low tune of 28-32hz or just go sealed with it. I want it to bump hard, deep bass and want some sq out of it. SO will that low tuned ported box give me a good sq but also hit hard?

How much can these take cuz my saz-1500d is feeding them pretty well but sometimes it sounds like they can take a bit more power...???

Hey scott, nick, or shawn, What box size and tuning frequency do yall suggest for my sub? The box I have it in now just isnt working. The sub sounds like it is bottoming out on certain frequencies and i only have the gain about a half of the way up. Its currently in a 2 cu. ft enclosure tuned to 33Hz. Any suggestions would be greatly appreciated.

I need some one to send me a template for a 15" Btl So i can see if i can fit them before i buy them. Also so i can get the holes cut for once they come.
