I need to replace it as there is something wrong with it.
I had to set it into the MMI to minimum as it makes some weird noise lol
It is knackered

Had to read all the thread in here.
Still sticking to the subwoofer i mentioned above.
If anyone can give me an advice with the amp please.
Will this one JBL GTO 751EZ ONE (1) CHANNEL MONO CAR SYSTEM POWER AMPLIFIER be bompatible with this sub: JL Audio 10w0v3-4 10 Inch 25cm 300 Watts 4 ohm Car Sub Subwoofer

Thank you for any help

you need to choose the lowest frequencies . JBL gives a nice sound.
300watt saabwufer+ 500wats amplifier

need to improve shelf under sabbufer. if this is not done there will be strong vibrations in the car body.

Let's say I am choosing that subwoofer. The amp is not good for that I suppose?
I need to find a 300 watt amp?

As is well documented, there's vibration in the rear deck at mid-high levels of bass because the wafer-thin subwoofer is there (and I'm guessing sound engineers aren't responsible for interior panels and didn't care).

So, whether keeping the existing sub or adding a new one, what's the west way to eliminate the rattle? Thanks!

Waaazooo

I used dynamat type material (raamat) and also a cellulose material they sell with it. It worked great.

Can you elaborate of where and how you applied this? Is it just on the underside of the deck or something?

Waaazooo

It's a peak and stick material. It's pretty heavy..
You cut the tiles to the shape(ish) you want. Stick them on the metal. Use a roller or your hand to make sure there is good adhesion. I tried to google some videos on you tube. There are many, just not for the a/s6 c7. You can usually go to an audio shop and for a few bucks they will do it for you.

You need to add a CLD product to the metal surfaces of the rear deck.

CLD = Constrained Layer Dampener

Some common products are Dynamat, Hushmat, Stinger Roadkill, Focal BAM.



The CLD prevents metal surfaces from resonating.



After that, you'll need some closed cell foam to provide a buffer layer between the rear deck and the trim panel. That way if the panel vibrates it does not hit against the hard surface and cause buzzing.
