Hey everyone, well I got a question for everyone, I just got 2 SQ10's installed with a NINe.2x amp to power them....well, I took it to Ultimate Electronics in ABQ, NMand well, I got home, woke up, went to have lunch with my dad, started it up..and the driver side sub sounds like ____, sounds like there's loose change INSIDE the actual subwoofer, its rattling really BAD!..so I need help Please, I leave for texas in 3 days, and can't be driving with a HOPEFULLY NOT broken sub...im a totaly newb..I don't know how to "tune" it, so if anyone can help, please PM me, or leave a comment on here, thx guys for all the help!!!!!!!

 

And I forgot to mention..its a 2 Ohm..wtf is the diff between 2 Ohm and 4 Ohm ?? A friend of a friend is saying that I got ripped the ____ off, that he hasn't seen 2 Ohm's in over 7 yrs :/ that EVERY sub that is made only comes in 4 Ohms....

 

Number 1. I would take it back to who did the install and have them check it out and fix the problem.

Number 2. Get a new friend that is not an idiot or one that know electronics. I have the same subs and the same amp and the subs are 2 ohm svc.


Hope you get things worked out.



John

 

^^^^^^ yeah...I still currently have 7 on me..im either going to sell them or see if there is a way I can get these to work..because I dunno, I am so stressed out right now, I feel I've gotten ripped, which I could be totally wrong...I am soo ____ed off right now. I trusted this so called "professional" and this goes and happens to me

 

just to name a few things that may have happened - either the wires are ratteling agaisnt the inside your enclosure (i wrap mine with some foam padding), or he dropped some screws or something in there, and thats what is ratteling, or he didn't properly set the gains, or he tried to connect both subs together in a way to get them to 4 ohms, but set the gains on the amp for 2...Did you personally visually inspect the subs before they were installed - is there a chance that one sub was ripped or town? Do you think it may have been blown during or before instal? If you have more then 1, swap out the noisy one and see if the issue is still there.. if it goes away, the problem was with the speaker, not the setup or install.
could be any number of things, the speaker polairity may be reversed just to name another posibility, but your "friend" doesn't know what he is talking about, so dont listen to him...
I would go back where you had the work done and tell them what you don't like about the install and demand either a partial refund, or that they fix the rattles and set up the system right.. Also, Size, shape, type, and design of enclosure will have a lot to do with how your subs sound.. if its a ported enclosure there is a good change that some butt connectors or a few screws or some debris got into the enclosure while it was being insalled. I am sure if he is a true "professional", he will correct the mistakes and not leave you high and dry. Why didn't you take 30 seconds to test eveything with him when he was done with the install?
4, and 2 ohm subs are made every day... nothing uncommon about 2 ohm speakers, they have less resistance then 4 ohm speakers and therefore can handle 2x the power is installed and hooked up properly..
i have a dual 2ohm voice coil speaker that is hooked up and provides 1 ohm of resistance... and yhes, it is from elemental designs as well... sounds like god when it's hooked up to the nine.5...

 

WOW, yeah...the installer aint gonna refund me, I asked him MANY times to fix it, and he just "looked at it" and said it was fine..and yes, for about 15 mins he showed me how everything sounded, how it works and crap, and it sounded perfect! Then he says "okay im wasting too much of ur time, get outta here!" so I was like uhh, okay(it was closing time) drove halfway home and I noticed the rattling, I thought it was a loose bolt also from the dash, but nope, took it apart and looked at the cone, and it was completely cracked off..its blown....and I also looked at the settings...the hz, was all the way down to about 2, its like he didn't set it...and also "Bass Boost" was on, which I told him I didn't want on, so either it blew, and he "fixed" it but it only lasted for awhile, or he screwed up real bad on the wiring, because it wasn't bridged either...if that makes any difference...but I just had lots of problems....hoping when I get to Texas, I can find a set of other subs and get them installed by a REAL installer, and this time ill stay there to observe what the hell he's doing, because I've been to installers before, and they completely cut an unnecessary wire, so I can come back to them, and don't even tell me, until 2 months when the thing completely screws up my ride...so I guess im just gonna have to start learning and do stuff myself, kinda hard to trust these "professionals" anymore after I got jipped twice, from these expert installers

 

Dude. It sounds like the installer didn't know squat about setting up the subs for install. If your box is tuned to a specific frequency in a ported enclosure, you need to roll off the rest below that bump. It's call an infrasonic filter and works the same way as a crossover. If you had a sealed box, you would have no problems with the sub frequencies as the natural performance of the box would slope it off. With ported, you have a velocity limiter which when the volume of the concussion exceeds the mass of the limiter, your sub can bottom out and fracture cones, split spiders, or rip the surround. I'd _____ out the manager of the place who did the install.

But I digress...

What I would personally do: Have a box professionally built to your specifications. Spend the extra cash on the box to have it done perfect. Don't buy a prefab box. The box will be your end goal for learning how to build your own. Learn the techniques used when the shop creates this box. Ask the car audio specific shop if you can be present when the box is made. Don't just buy speakers and throw it into a box... buy the speakers you want, then have the box built for them (or do it yourself). The prefab boxes aren't worth crap if you ask me. Check out some of the videos you find on youtube for box building as well. There's tons of information out there.

Skip the consumer grade junk... go professional grade.

 

Also I would say that eD equipment in NOT consumer grade junk!

 

Would you please provide some examples of the consumer vs professional "grade" you're referring to? Would the cost be the same, and if not, what about people on a budget? Is it not possible for many people to be happy with "consumer grade" equipment?

 

Consumer grade ED is not. What I'm talking about is not to purchase the equipment from a large corporate retail store such as the "Not so ultimate" electronics. Instead, go down the street, around the corner and into a garage that might closely resemble the one/two car repair garage filled with mobile fidelity and not much else. Those are the professionals with the right tools and know how to design and build the right equipment in their sleep. The small shops to avoid like the plague are those who proudly display the DEI equipment. You should avoid DEI like the plague (think Audiobahn and the ilk there in). Most shops who offer equipment such as Xtant, JL, ARC Audio, or similar are the ones who are the professional grade. You will pay a little more for the right equipment, but it's done correctly the first time.

 

Oh, so you're really saying there are specific brands you like, that typically can only be found at smaller car audio only shops. Ok, just wasn't clear what you were implying, so I had to ask.

 

Yeah, sorry about that... clear as mustard I spoze.

 

The subsonic filter electronically rolls off/filters the reproduced frequencies below the chosen frequency setting. This is set in a ported box system to the port tuning frequency of the enclosure. This insures that the sub does not try to reproduce notes below the port tuning frequency and unload the driver, causing damage. Sealed boxes do not need this enabled since they cannot unload the driver due to the air spring/cushion that always is in effect.

Elemental Designs equipment is above average mainstream equipment. Dollar for dollar, it beats the big box brands (entry level sony/kenwood/jvc/pioneer) to shame. Are they equal to ARC/Audison/Zuki? No, nor do they cost as much. JL, IMHO, is over hyped and overpriced.

I have had my eD stuff since I bought the 'B in 11/05. You cannot compare the prices "one for one" to normal retailers because eD does not add on for the middleman/dealer profit. They are a direct sales manufacturer. Less overhead=less cost to buyer=more bang for your buck! Go take a look! And GREAT customer service!

OP, you need a new car audio bud and a new install shop! Or learn here and DIY!

Go to: >>>Elemental Design Audio<<< and check out the recommended box for your subs. They provide dimensions so you can build your own or buy direct.

Totally agreed. ED is not crap. The installer is. Way to misread what I posted.

*cough*If your box is tuned to a specific frequency in a ported enclosure, you need to roll off the rest below that bump. It's call an infrasonic filter and works the same way as a crossover. */cough*

 

^^Huh? You never called eD junk! And I never said you did?!?

I was referencing the "With ported, you have a velocity limiter which when the volume of the concussion exceeds the mass of the limiter, your sub can bottom out and fracture cones, split spiders, or rip the surround."

Velocity limiter? Concussion volume? Limiter mass? What? I didn't misread that!

eD is a good value for the money. Can you buy better? Sure you can! Can you spend the same and get way inferior stuff? Yup! Reasonable (for most daily driver installs) equipment at a great price! And great customer service. They will take the time to walk through your entire system to sort things out with you.

^^100% correct! Now that I understand!

Robert

 

^ Nice choice of components, can't really beat the price:performance of those particular Dayton's, and kudos for going with a large format tweeter, rare in a car implementation.

 

Thanks!

xB owners are lucky...there are gigantic openings in the dash corners. Plenty of room for upfiring large format tweets! The Daytons (running active) kick butt for very little money!

OP, your SQ10s should pound on a Nine.2X! Any updates?
