I was at a local dealership a while ago here in Finland and talked to one of the sales staff. He told me that the first Bassworks kit that they'd installed had been fitted so that the amp ended up inside the dashboard.
Only after the customer had informed them and questioned the reasoning behind it, had they realised that the amp had to be accessed to change the settings. Apparently they have since been installing them in the glovebox, which does make more sense.
If only the concert packs weren't so darn expensive...
Nearly £1000 installed.
