I installed a pioneer sealed 12” subwoofer about two months ago on my 08 G35x sedan with Bose audio.

My problem is after the first month the stock Bose subwoofer started to raddle and shake, creating lots of unpleasant noise when listening to heavy bass songs. This got worse as time went by.

Im just wondering if anyone has the same issue or has a solution to stop the stock subwoofer from rattling because it really ruins the music.

thanks.

 

Bro ... You cranked it too loud and your speaker is blown.

I'm almost 100% certain the braided gold wires going to your cones have simply disconnected . At least one wire. You can verify this by holding the wire to TOUCH the part it came off of .... then turning on the music. It should sound perfect . When you let go .... it sounds like a$$

You can fix this by 2 methods:

1 Disconnect the brown plug . You already have a sub. Which drowns out your stock sub. You can't hear it anyways. Unplug it
2. Solder the wire back on. This requires a soldering iron. Solder. Flux. The sub DOES NOT have to be removed, and if you're careful you can solder it laying down in your trunk . This works and has been tested.

Personally, I'd fix the problem. But if you can't solder, or just don't wanna fix a broken speaker then just unplug it.

 

thanks.

the thing I know for sure is that I never cranked it past 85% knowing that it has a possibility of blowing. I’ll update after I take a look at the golden braiding, though how should the disconnection of a wire cause rattling like that?

 

If you remove the felt panel
Look at the sub
You'll see 2 gold wires. They're braided.
One most likely broke.
You'll have to resolder it back on.

In my experience, just solder alone isn't good enough.
Mine kept breaking, at the solder joint.
The best thing to do is buy new wire from a speaker shop.
The reason why is because the wire is shorter.
You add solder, it becomes solid ... less travel
When you crank it, the speaker wants to move.
For now, just disconnect the speaker.
It's in the back and your aftermarket sub drowns out most of the sound anyways.
In the future, after you fix it , adjust the speakers to the front more.
Less chance of it being blown.
Turn down the bass 3 bars from max.
