Does it have an auto on feature?

With the JL subs set to auto, increase the sub output on the 7005 and lower the volume on the subs themselves until they are at the right level with the spl meter for your normal listening level. That should help if they are not coming on as fast as they should. You'll be sending more signal level / voltage to wake up the subs better.

I had that problem with those auto on subs before. That usually does the trick.

Maybe the information above warp posted in another thread about some trouble he was having with the auto on on his JLS will help you.

Instead of dealing with the auto on issue, I just set it to "on" instead of auto, and manually shut them off when I'm not using them. That's a surefire way.

Not if they are actually failing

No . what i mean is that there is no power to my sub when i on the power.
It suppose to have green light on the sub when you on it.

Sounds like the power supply up and died. So, it's two for two now?

Can you get your money back?

I think you are correct. Then now is the problem, if i get another sub, will it happen again?
and i need to know what cause this so i do some preparation before adding a new sub.

Thank you markw

Sorry, my prognosticative abilities are kinda weak. Maybe you just got two bad ones from the same bad batch and the third will be from a differnt batch and be fine? Dunno...

and i need to know what cause this so i do some preparation before adding a new sub.

Unless you aren't telling us something, I can't see what you're doing wrong. You're just plugging it in, right?

 

[weichi1213]

yes i just plug it in. at first it work very well (the led light is on). after a while i notice the led light is off without any warning. I checked the fuse and it is ok.

Btw i bring the fuse to an elactrical shop and the shopkeeper say my fuse is ok. he say maybe i need to get a voltage regulator. (i plug it into a surge protector only)

what do u think

thank you again for your time

 

[markw]

Dunno.

So, you say it works again after a while? That's a new bit of info.

Try a voltage regulator and see what happens. I'm outta ideas.

 

[weichi1213]

No, it is not working.

i think i will get a voltage regulator and see how.. sign....

 

[markw]

When you get a working subwoofer, try plugging it directly into the wall.

Hi Markw,


you are right again. they said there are problem with their batch of stock. The subwoofer can use for few hours only. after that it can't wok anymore.

Now i need to go out find another set..
