JL 10W3v2

Who has it and who likes or hates it...



This is the power chart.


I think a 250 mono amp will keep me out of trouble, but will it be enough to really kick in a Mercedes 300e (four door car, similar to a e34 five series)

I've got a pair of the 12s and I'm fairly pleased. I dunno how much bass you're actually looking for, but by the way you worded your question I'd assume you'd want a good amount, possibly even more than that.

Regarding your amplifier choice, you don't have to exercise so much caution with power ratings as long as you aren't an idiot and know the limits of your woofer. 250 watts is fine, though. If you're going sealed, increase the size of the box to complement this change in power.

If you're looking for more output I would definitely go for a ported enclosure tuned to around 30Hz. The box will be quite large, but it will definitely be worth it, I'm sure.

don't forget you can blow the subs if there is not enough power, the distortion due to the lack of power = POP.

That is incorrect and is a hugely common misconception amongst people who aren't the hobbyists. If this were true, every time we turned down the volume on the head unit, all our speakers would blow from "distortion due to lack of power."

Two things blow speakers...well actually one, which is being an idiot, but the two causes for speaker failures are thermal failure and mechanical failure. Thermal failure is what you get when you feed your speakers a clipped signal for extended periods of time, provided the power the clipped signal is giving your speakers is enough to blow them. Highly difficult to do with a subwoofer, but in the hands of an idiot, a woofer being fed too much power AND a clipped signal will certainly blow it. The other, mechanical failure, is rarely seen. That's when you do something like blow the surround off the cone. Thermal failure tends to occur before mechanical, and the peak power rating for a subwoofer will give you about what it takes to get you a thermal failure if you play test tones before clipping, but both are possible. 300 watts RMS by JL's standards means the speaker could take 8 hours of an unclipped 300w 0dB test tone from and still be fine.

You have nothing to worry about. I suggested you increase the box size because it makes the woofer more efficient, as the "spring load" effect from a sealed enclosure loosens up as the box size increases. This means the speaker can reach full excursion from less power than required from a smaller box.

shoot man I don't know everything about car audio but what I know, I know. FYI I know many people in the car audio business and you are a tard. Too much power OR really low power can blow the subs.

Why do you think that all the cheap fools that buy "nice" subs and skimp out on the amp end up blowing them w/ the crappy underpowered amp?!?! Well if there isn't enough power to supply the subs then there is a lot of distortion. The subs will try to hit like they should if they had enough power but the distortion will cause the subs to blow. PLEASE if you don't know what you are talking about, STFU.

Really man, here I am tryin to help this nice man out and you are spreading false info. go home and read a book, learn something.

Wow man are you fucking kidding me?

Eat shit and die slow. I don't give a flying fuck about the sales people you know. Do they have any knowledge of basic physics or electrical engineering? I doubt it. Most of them are too fucking stupid to be able to tell you your nominal resistance with subwoofers.

If you are actually interested in knowing the basics, go through all of the links on the side...

Now, in your words:
PLEASE if you don't know what you are talking about, STFU.

ehh agree to disagree then. I know people in more than sales and I'll leave it at that. I don't need to prove anything to you. You can blow your subs for all I care.

Why don't you read the page I linked and eat your god damn words? Is it really too much for you to admit you are clearly wrong? What will it take? Say Luke comes and tells you you are wrong and so are your "audio friends", then what?

Do you even know what a clipped signal is? Christ...

Oh, and BTW, I've never blown a speaker in my life, and I've had aftermarket stereos since 1998.

[StereoInstaller1]

OK since BOTH you guys are tards, let me explain the issue.

What blows speakers is clipping, which is caused by asking too much of an amplifier.

Asking too much of an amp is stupid.

Clipping simply enough is the amp producing DC voltage instead of an AC waveform.

Too small an amp causing speaker death? No. Whoever says otherwise is simply wrong. a 10 watt amp producing 1 watt is fine. a 1 watt amp attempting to make 10 watts is the issue. So, it boils down to stupidity.

Quit yer fucking arguing!

Jordo's 10W3V2 sounded OK, but mostly because I built the fucking box. Most people are amazed by decent bass...Jordo's did rock.

I just think they aren't worth the money.

well I guess you can't read very good? I don't care if luke agree's w/ you. I know people all over the car audio spectrum. EAD and stop trying to start stuff. Get off your high horse and realize you can be wrong.

if you want to act like you know stuff then feel free to PM me or AIM me anytime, BACK OT!!!

BTW I have never blown a sub either hot shot

...OK where in my posts did anything I typed differ from what you just stated?

Guy tells me I'm wrong, and makes totally unnecessary personal attacks. I was not rude in any way when I stated my position. I give him a link explaining why he is wrong and I was hoping he would apologize for being an ass...but no, he's agreeing to disagree with absolutely NO proof to his argument whatsoever. I don't like myths being spread, I'm sorry.

Oh, I can definitely admit to being wrong, BUT, I'm not wrong, can't you fucking get that through your head? Ugh...

[asubimmer]

back off man, I'm done tellin people my connections. I know too many people and jealous fags like you get pissed when they hear about them, and if you don't know what I'm talkin about then GOOD. I don't want people to think I am trying to flaunt anything.

Like I said keep crap like this to PM or AIM and keep the board clean.

[kylebes1]

Thanks for shititing on my thread. go butt screw each other on max or something. even us PMs we don't care about your arguement. No matter if you were right or not Dave, I find it difficult to take advice from someone who will fight with someone who puts a es spoiler on a 318is.

As usual I end up going with what Luke says. I agree with him, but I a second opinion is always welcome.

The only thing I have trouble with is picking a decent "less expensive" alternative.

Hey...check out Crystal! I am gonna be a dealer soon. I will be giving buddy deals here soon. the "Pro" series is cheap and hot.
