Audi S4- Speaker box and amp rack

Here is a build done on an '04 Audi S4. First installing a Kenwood headunit DNX6960 in the stock location and still utilizing the factory Bose amp and speakers. The chrome trim was retained on the aftermarket dash kit to keep with the factory look. The external base knob was then installed under the armrest where the factory phone would normally plug in. It is fairly hidden but very accessible. A ipod adapter/plug was also installed and is located in the glovebox.
The next thing to do was strip the rear trunk out to start building the custom sub enclosure and amp rack. Using the factory panel to build off it was extended out to accommodate the amp and sub. Once these was formed to the desired shape using poly-fleece and resin it was time to move on to the box and frame. The speaker box was built using MDF front and skeleton ribs to help form the shape. Using Poly-fleece and resin, the basic shape was formed. An additional fiberglass coatings along with more resin gave it strength and denseness. Dynomat was also used on top as well as in the rear quarter fender to help in vibration and sound dampening. The amp frame was built next also using MDF and routed to smooth out the traditions. Once everything was fitted it was time to wrap it in a Micro Suede two tone to match and compliment the interior pieces.

ENJOY! I know the customer will.


  1. Much Thanks Drew! Your ability to produce work like this and attention to detail is unbelievable. Next in line....AIRBAGS ;)

  2. wow great work bro... this is a great set up.. I have shown a few people with great reviews. I have a 2001 Jetta 1.8T so its pretty much the same trunk set up..

    with this in mind I just got in some training on custom enclosure to see if I can work something similar..

    I have never tried anything like this before but I love the challenge.. from what I know I need about .6 cubic feet for the shallow mount speaker..
