This customer just wanted great sound without all the flash. With OEM integration and our fabrication techniques, we hid a full sound system within this small Audi TT.
As always, we taped up the exterior to avoid any damage during the build.
We put some of our best Hertz components in the doors, with sound dampening to seal out all frequencies from behind the speakers. This and the foam speaker surrounds focuses the sound into the vehicle without any interference, making these components sound as good as possible.
We built the subwoofer and amp into the spare tire compartment in the trunk, leaving everything else untouched. The flush mount leaves room for the trunk cover even while the sub is at full excursion.
With the trunk cover in place, this TT looks perfectly stock. This leaves the same cargo area, and would-be thieves wouldn't think that is anything to steal.
Lifting the trunk floor exposes the battery and tool kits. Besides the loss of the spare tire, there was no loss of functionality or permanent modification to this TT.
