So, where is my Amp located in my X5. Under Spare Wheel ???

[Julwalsh]

Hi all

Can somebody please clear this up once and for all. My Amp has gone faulty and I need to try and get to it to inspect/replace it. However, I have heard lots of different comments to where it may be situated. Can somebody PLEASE tell mw where it is and more importantly what it looks like.

If it helps, my X5 is 2005 model, 3.0i Petrol.
It has a Mk4 Nav Unit, TV etc.

Yesterday I had the spare wheel out and under that there is a dome. I undid the 3 bolts in the dome and under that (attached to it) was some sort of Air unit/Air pump etc. I still can't find my Amp and to be honest I don't even know what I'm looking for.

Thanks all
