Im looking to install an aftermarket h/u to my 2002 s3. It has an interface box that is about 6in x 8in x 1in deep (Like a very small/ thin amp). I have been looking for somewhere to locate this but the only location I have seen is behind the passengerside rear quater pannel. I was hoping for somewhere closer to the front. Does anyone have any idea if there is space behind the dash or under the centre console for something like this??
