What's peoples thoughts on the soundstream xxx 15 ?

 

A loud ass sub... 89db sensitivity, and rated at 8500w rms... Quad 4" coils... It's a monster...

 

I just bought one that was brand new and one coil doesnt read,for 230 shipped with insurance.it needs a recone that is 130 shipped from soundstream.so the subs going to endup costing me 360 complete. You think its a good deal?

 

some pics of the 90lbs beast,hey matt this sub will destroy my Fi 18 Bl right?

 

If you can feed it enough power it will... You'll need at least 5 or so kw's... You're going to have to sell both of those amps of yours, but it could if you can find enough power for it, then yes...

 

What I was plan on doing was trying it out with both of my amps.Then if it dont do well may looking into something larger or 2 more and run one on each coil.

This is what me interested in this sub.You can tell it hit soooo hard when it show the sub pound with his seat in the video

 

He's running about 10kws in that truck... If you want that much power, you better save up for some serious electrical support....

 

looks like an eclipse ti basket

 

What the xmax on these things? They look like it has some serious stroke.

 

It's similar but not the same. It's probably to get the biggest spider possible in there which like richardparker mentioned, helps with the massive Xmax, which I can't find published anywhere. Maybe call SoundStream and ask them?

 

I think its 39.88 one way.

 

ok also gotta remember thats sealed youl never get that amount of output from a trunk unless you wall it off. 2 do not i repeat do not run one amp to one coil i've heard some very bad stuff about doing that

 

It can be done, you just have to spend the money to get amps that are strappable, or get something like a Maxxlink.

richardparker, if you're going to run one of these subs, sell all of your equipment, and buy a ~5kw amp (something like an Atomic 5k, RD 5750.1, etc) and run the 1 amp on the 1 sub... Also, you're probably not going to be able to do this out of your trunk... If you plan on it, it'll have to be sub/port forward sealed off from the trunk. Also, NO SUBS INSIDE THE CABIN OF THE CAR THIS TIME!!! Sorry, you can't do that with a sub like this if you want to get loud. You're also going to need probably a grand in electrical upgrades, by the time you add up a good alt, battery bank and wire, it's going to cost quite a bit, so just be prepared...

 

How would this sub do in a forth order ?,I think it is.
If this was your car and wanted to keep the box thats in the seat to stay there.How would you try to make this work,witch way to fire sub,port,box size.I can cut up the back deck,but I want the back seat how it is.

 

You'll need to take specs to find out what it'll do in a 4th order or any other sub specific enclosure.

As for sub/port placement, I'd go sub/port forward, sealed off from the trunk, with the box taking up as much space in the trunk as you can get. Also, you'll want a big ass port... This means you're going to want as little between the sub/port/baffle and the cabin of the car as possible.

If you're set on keeping the 4 12s inside the car (which like I've said all along isn't a good idea, but your car), you might be able to get a 4th order ported through the rear deck, but like I said, you'll have to take T/S specs on the sub before you model it up in a program like WinISD. You can buy something to take T/S specs from parts express

 

Can you tell anything from this? I had to put the whole link because the charts did not show up right.

Yep, that's what you need... I'm really surprised how high the fs is on this sub, but then the 18's fs is nice and low... Your best bet now is to download some WinISD and plug the specs in, and check the response graph...

 

Is the FS what it should be tuned to,I dont know what FS stands for.
Also would a 6500 xxx be a good match for the xxx 15 ?

 

If you're running an 18v setup, then the xxx 6500 would be a decent match... Probably a better match for the sub would be a xxx-10k, or something more along the lines of a sundown 4500 (may not even be enough) Atomic 5k, RD 5750.1, etc. The xxx amps are very overrated, and do not do rated power, nor are they efficient at all... A 10k will need at least a 300A alt, and 3 good batts. Something probably better would be one of the other amps I listed, or some other combination of 5-7 kw...

Fs is the resonant frequency of something. For example, up to this point the fs of my car has been 43hz. The FS of a sub is the frequency at which it will play if powered up free air

 

what would be cool is to redo the back seat panel with the 18" keep the 12's in the side seal it like it is now but with the 18 and port man that would be sick

 

Before the seat was finished.It was all open into the trunk with the port facing forward.It did get really loud

 

Both my 18's sold today,whoo hoo.Now the xxx is paid for and have cash in hand for the recone.
Now it needs power and the best amp I can find for the money is the xxx 6500.Seller said it will do 4500w rms on stock charging voltage.Also its good to have because when upgrading electrical the amp is capable of over 7000w rms @18v.I think this will be a improvment over trying to run both BXI1608d's.Dont you guys ?
I will probally only have to dump 1 of the hifonics amps to pay for it.That will allow me to keep 1 for the 12's.

 

How much are you getting the xxx 6500 for? Those amps are hungry as balls... I wouldn't go that route if I were you... Plus it sounds like your "seller" has been running it on a stock electrical system, which is no good, and probably caused all kinds of problems with the amp...

 

yea and the seller can say he has a 12" wang but would you believe him lol??. I would get a diff amp a sundown 4500 yea that would slam im gonna get a older 3k when i redo my system thinkin of a 21 ia dp just for kicks and giggles

 

Not sure of the exact price yet.But it will be extreamly low.In the dealing process.

 

I had a 12 that wanged pretty good...

And I can't wait to get my newer 1500 in for my current rebuild... It's gonna be nice, unfortunately, because I'm pulling the brace out from behind the back seats, I'm getting bumped up to the SS NW class, which is going to suck, unless I can pull mid 40s out of the setup, in order to not get completely embarrassed...

And why a 21" IA DP? You can get the same effect out of a good 18, in a good box... You should realize that most of the sound of a sub setup is in the box, and there's no way you'll be able to stuff that 21" DP into your trunk unless you suffocate the hell out of it...

 

re read the statement 12" wang not a 12 lol. i've just been wanting one. and i may be buying a jeep or something on that line and would run 2 of em. and nobody around here has one like them so figured eh why not. i really dont care if it does not do full potential

 

With the 2 21's you will be head for minutes before arriving,thats for sure.Also bet you will have some monster flexing along with some car damages.

 

Meh... Cone area is a crutch... Get loud with small subs, then I'll be impressed... My new build is 2 10s, but they aren't rated for much power. I'm either thinking 4 (or 8) 8s (probably 4 since I don't think 8 will fit the way I want) or keeping the 2 10s and maybe upping to beefier 10s and maybe more power in the spring...

 

yeai kno i was loud as hell with 2 12's. but i want something for that holy shit wtf are those effect nothing like a 21" sub lookin back at ya. if nothing else i will go for 1 18 in the trunk then 2 in the big car

 

The only way to get an 18 in the trunk and get the full effect out of it would be to have it firing forward, and seal the box off from the trunk... That would mean pulling the rear seat brace, and likely cutting the left over... That's what I plan to do for my 2 10s, but we'll see I guess... The subs are on their way here now, so the build will begin soon...

 

richardparker, if you want to run 1 amp to the sub, here you go: http://www.caraudioclassifieds.org/f...ad.php?t=16319

Cactus Sounds Team Cactus 5k... That'd work well for you...

 

Thats I bit out off my range,I have seen that amp and Iwish I could get it.All I got to work with is my 2 amps and 150-200.Both amps I could get 170 each,but with both amps sold and my money the most I would have would be some where around 5 and change.

 

Then you're better off saving some more money, unless you can find a couple 2-3kw amps to stap...

 

Can I run 2 amps on this sub without problems if there tuned identically.What the proper way to tune them identically?What equipment to use?

 

Yes you can, and you don't have to even set the second amp. All you have to do is buy 2 amps that are "strappable" or some with a Master/Slave function. There are diagrams/pics on Sundown's website on how to do it properly, but your amps may be a little different, depending on the exact equipment you use...

 

my anps are not strapable.They didnt have the master/slave options on the till you get to the 2000w and the 2600w of the brutus line.So now that my amps are not strapable can they be tuned so they perform identical,till I figure out what I plan on doing?

 

With amps that aren't strappable, you can buy something like a Maxxonics Maxxlink which is a strapping module (I believe that's what they call it). I wouldn't try to set 2 amps to get the same power out of them, but that's just me... I'd rather either buy something extra that takes all the guesswork out of it, or buy amps that are strappable. Just me though...

 

Are you sure this works for amps that are not strapable?I watched a video showing them hooking amps up,and the amps they were using were strapable already.

 

The Maxxlink? It's designed to strap amps that aren't strappable. Call John or Mike at Maxxonics if you don't believe me. I've met both of them, and either one will gladly help you out with whatever you need.
