Possible Blown Sub? Help please.. :)

[speed_demon1978]

Hi all - hoping for some advice from the guys on here regarding the sub on my 2007 A8 D3 with the standard sound set-up. The other day after a few months of living with a humming sound upon starting my car (from the sub) I think it has finally blown or has a fault as I`ve lost all sound from the rear sub.

Will investigate potential wiring issues, but aside from replacing it with the same standard stock sub, are there other alternatives out there which would be compatible and potentially a better alternative to the original Audi sub?

Thanks for all your help. The lack of bass is driving me crazyyy
