Well as I've mentioned a few times now I blew one of my subwoofers a few months ago, which I may remind you STILL has not gotten back to me yet, anyways, I have 2 12W3's rated 250 RMS each, and a rockford power bd1000.1 wired at full power for both speakers, (500 rms each speaker) and EVERYONE I've asked tells me is fine beacuse the 12W3's should be able to handle that with no problem.. I've been running the one subwoofer for the time being, which puts the amp at half power (500rms) which is the same it would be getting as if it were wired with both subs. The other subwoofer blew when I was playing bassy music for just a few minutes, weather or not damange happened over time I don't know, but now again today I almost blew my other sub with a semi bassy cd, nothing like the one I was listening to before.. the gain is a little above half as far as I can tell, the amp doesnt exactly have a detailed gain **** on it, and the punch bass was just above half as well, I wasnt cranking at a really high volume but loud enough.. And I started getting that smell (sub fring baically) so I immediately turned it off and waited till I got out of work to turn it back on, and now it seems to work fine again.. I'm just tired of not being able to crank the stereo without worrying about blowing the speaker and spending all this crazy amount of money on my stereo and my friend has a POS bandpass box with a peice of wood he found in his garage caulked in place of the plexiglass that cracked and 2 radioshack 10's in it which are a few years old, and a clairon 240 RMS 1 channel amp and he system pounds very loud (much louder than mine) and he can crank it for as long as he wants as loud as he wants.. Basically my guess is these speakers really can't handle 1000 RMS.. If anyone can help me figure this out then please do so, if not I think im gonna switch to either another set of MTX's and get 8000's or go with rockford punch hx2's or may even say the hell with it and get power hx2's and ill never have to worry about overpowering them cuz they are rated up to 1000 rms.. thanks for help..

hey wasap. well it sounds like you have the wrong combination of components. the amp you have is too powerfull for those subs in that configuration. it is true that JL Audio subs can handle more than they are rated for, but going with double the recommended rms rating will prolly blow the speakers. i've known people that have pushed JL's 50 or 100 rms over the rated limit with no problems. how do you have it wired? i think the speakers are dual voice coil 6 ohms. do you have the speakers running in parallel? check out JL Audio's website, they have a very well written wireing diagram for hooking up two dual voice coil 6 ohms subs (its kinda tricky to have it wired correctly). you also mentioned that you're not happy with the sound of the subs, while your friend has two radio shack 10's that pound. it says in the sig that your sub enclosure is custom. did you measure out all the cubic space requirements and stuff? JL W series subs really sound different depending on the enclosure type and size (cubic feet). is your enclosure ported or sealed? there is a certain sweet spot that the speakers hit with the correct cubic feet of airspace. the enclosure has alot to do with how good the subs will sound. I've heard a single 10 in a computer designed home audio enclosure being pushed by 300 rms drown out 3 of the new square kicker solobaric subs being pushed by a 1000rms amp in a regular sealed box!!! ever wonder why reg cab trucks slam really loud? its cuz the cab acts as another enclosure for the subs and they resound better. I would recommend you first read all about the subs you already got (cubic feet airspace requirements, sealed/ported enclosure?, wireing diagrams) cuz they are good subs, then double check the sub enclosure to make sure its the right type of enclosure for those subs, then I would either turn the amp down so its not overpowering the subs (maybe just run the 12's off 1 channel @ 500rms and then power some 10's or 8's in the doors / backseat??) or i would sell that amp and pick up two amps, one that will correctly power those subs, and another 4 channel for your high's (they will sound much better than running them off the deck) and then see how it turns out. FYI, the subs in your friends garage sound good because of the enclosure they are in. bandpass boxes usually hit harder directly in front or behind the box than other types of enclosures, and the enclosure was prolly designed for those speakers. good luck!!

tell us the type of voice coils on the w3's (dual 4, dual 2, dual 6 ), how the coils are wired (parallel, series), and how the subs are wired to the amp (bridged, in parallel or series, or stereo) ?

I'm not terribly familiar with the bd1000, but I'm guessing it delivers 1000 watts into a 4ohm load ?

Also what size enclosure are the subs in ?

For what it's worth, I have a pair of 10w3's, each on a Crossfire 1000D. However, I only jam it for 5 seconds at a time. But, the w3 should be able to take 500 watts for quite some time.

Also, is the amp clipping ? What means did you use to set the gains ?

With the answers to these questions, I should be able to give you more specific info .

The rockford bd1000.1 is a 1 channel mono amp, its rated at 1000x1 @ 2 ohms.. I have the DVC 2 ohm subs, the coils are wired in series, (2+2=4 ohm) and the terminals are in paralel, 4|4=2 ohm, which basically means the amp is using full power of 1000rms.. Which does double their rated RMS, but like I said, lots of people have told me the speakers should hold up just fine to the speakers including some peoeple on here AND I even emailed JL audio technical help and the guy even said in his exact words "the speakers will handle the amp just fine".. There is defintely no distortion it sounds clear as day when you turn up the volume..

As far as the difference between the bandpass box etc., yeah I'm already aware of the difference, not to mention his box is inside a trunk which also makes it even louder, that was just me venting beacuse I keep spending so much money and all this expensive stuff and it doesnt work right =P

As for my box, I didn't construct it, its made by RYJO customs and its a dual 12" ported box, which I just now noticed could be my problem.. Now I could SWEAR I remember asking them about this and the subs I had and what the airspace they needed.. the 12w3's need 2.00-3.00 cu ft airspace in a ported box, I think my box is even less than 2.00 its possible even like 1.5.. I'm assuming this is pretty big problem actually? I'd probably need to use a sealed box in order to have these subs to spec cuz they only need 1-1.5 cu ft airspace, but unfortunally I don't like sealed boxes, I like the deeper bass, im not really worried about accuracy that much..

On my way home today I was listening to a CD with a normal amount of bass, nothing extreme at all, and I once again had the smell of it fring, which means this speaker is gonna probably be on its way out as well, and with my luck they wont warranty another one and even if they did it'd probably take another 6 months for them to get it back to me..

Welp I can't type anymore my fingers are gonna fall off, lemme know if you think its the box that's my problem or if its just the amp thats too powerful or maybe a combination of both.. thanks

ok ported box. That brings up new questions.

but for one, I do not believe the speakers will handle as much power in a ported box. The guys that give w3's big power typically do it in small sealed boxes.

So anyway , Do you have a subsonic filter on ? and what is it set to, also, what is the box tuned to ? Do the subs ever bottom out, or is it just the burning smell ?

Originally when I blew the other speaker I had the subsonic filter off but when I realized that I could just run the one sub I turned it on before using it again, and its still too much for the speaker obviously.. I'll have to ask ryjo what the box is tuned to I'm not exactly sure.. What exactly do you mean by the subs bottoming out?

CrazyHawaiian

easy solution: well since you keep smelling the burning smell, might as well get ready to ditch those subs. you already got your enclosure and a powerfull amp, so find some subs that match well with what you already got (find some subs that work good in ported boxes with the same ammount of airspace you got and can handle 500 rms each).

Or you could get a little crazy and check out the w7 series. run 1000rms to a single 13.5w7 (rated @ 750 rms i think?) in a custom box in the hatch. that would be INSANE!!! hehhe :P

in my truck (slammed reg cab s10) I have a single 10w6 in a small sealed truckbox being underpowered by a 200x1 rms amp. it slams for a single 10. you cant hear it outside the truck too much (which is fine with me) but it sounds great inside the cab and hits some pretty low notes.

Nah I couldn't get a little crazy =) w7's would probably be a LITTLE out of my price range at the moment espsically since I'd need a custom box =P I just did a T56 swap and Im broke! I cant even afford to buy new subs really.. the one is out for warranty and should come back fine im assuming, this one I got now is probably going to be on its way out I guess.. If they don't warranty it I guess ill have to take a loss on it.. I dont know what the hell to do at the moment..

turn the bass boost all the way of on the Rockford amp the quickest way to kill a woofer with a Rockford amp is to turn the bass bost on even a little.check the loudness on your radio turn it off make sure the bass is set to 0. because if any of this stuff is up thats going to be your problem with the ported box. another question is to make sure the enclosure is sealed everywher except the ports. if those are ported i highly doubt they have them in the right airspace.
If you need anymore help call me tommarow at work its Soundwaves 979-779-0065 you shouldnt be having this much of a problem...

I'll try keeping everything down, Normally when I was listening to the CD I was listening to yestarday there was never a problem with the boost up and yestarday there was so I don't know if the speaker will hold up to much more.. Where do you think I should have the gain set to?

KlayBuRn

sell your subs, and spend $200 and get a Power HX2, DVC 4 ohms, wire into 2 ohm, matching 1000 watt amp to a 1000 watt sub...

my Power DVC...

*ah*

SLAYER6669

iTrader: (1)

To tell you the truth I've been seriously considering buying 2 power HX2 DVC 2 ohms and wire em to have 500 watts each.. I'll get a new box for the correct airspace for those subs and then I can just pound the **** out of them =) But unfortunally I can't spend that kinda money right now..maybe after I pay off my debt from the trannie swap and pay insurance.. I'd rather have 2 subs then just one..

well guys im not trying to push stuff on you guys. i just use all the trophies and happy customers to prove im right.
but if you want to save money and get better sound your more than welcome to ask my opinion.
ive been in this industry for 9 years and have won more trophies than i can remember. and yes i wish they would move world finals cause i have do drive so far every year.
i can only recomend what is better because im a sell out. i dont care who it is if its better im about it. ive competed with kicker rockford alpine nackamichi mb quart jl audio liner power so many name i cant remember but they all are big at one time and then someone else steps up to take their place just dont get caught paying this years price for last years design stick with companys that are pushing the envelope. if you want to hear some really nice equipment come to my store check out some of the world class installs and hear some good sounds. im more than willing to help or if you need product shipped i can get you good deals because we buy more than just about anybody...
