Location of standard amp

[mmarksx19]

Hi all,

Referring to another thread of mine whereby one of my speakers isn't working (and it isnt the speaker that is faulty), I wanted to check the connections on the amp and find if there was an output on that channel.

My car is a 2007 A8L 3.0TDi with factory standard audio (not bose or B&O). My initial question is - where is the amp located in the car? I have seen reference to removing the battery to ease access but I thought all the equipment for sound/vision was on the opposite side of the boot!

would love an answer so I can investigate further.
