[Audi] A3 Morel

SQ Audi A3

This latest project from Simplicity in Sound was for a customer who campaigns a Stohr prototype in the SCCA’s P2 categories. As SiS’ Bing Xu explains, “The first time I saw the car, I knew I wanted to somehow get [our logo] onto it. and after some discussions about his daily driver, a 2007 Audi A3, we worked out a mutual agreement to give him a sponsored rate in exchange for some advertising for our shop.” Everybody wins. And of course we benefit from being able to share the frontstage install on this vehicle.

 

The goal for the system was to achieve a high level of sound quality throughout and maintain relatively subdued appearance on the interior. They wanted to integrate the Mosconi AMAS BT streaming device and upfront controller for ease of use and convenience.

 

The signal starts with a Pioneer AVH-X5600 head unit, installed via a Connects2 DD kit for the S3.

 

A cool feature that the owner envisioned and Joey Knapp of SiS executed, was to mold the Mosconi DSP control into the pop up lid of the OEM ashtray. So here is the ashtray in its normally closed position.

With a push the controller integrated lid pops up, allowing for easy to reach adjustment of the master volume (especially while listening to AMAS) and preset controls. As is the trademark now with SiS, the outer top edge of the controller button has been turned to create a shiny halo effect.

For the front stage of the car the guys chose a set of Morels, with the Supremo Piccolo tweeters going into a set of custom molded A pillars. The directive was to try and keep them as recessed and outboard as possible. SiS’ goal was to try to aim it to clear the big instrument cluster shroud to minimize unwanted reflections. Not the easiest thing to do given the large size of the Piccolos.

The ring baffle for the Piccolos was pressed all the way to the side with the bottom of the ring actually almost touching the metal A pillar. A dip was molded into the a pillar trim above so there is a smoother transition without and blockage. They are aimed semi on-axis and at a angle that clears the hump. the entire panel was covered with dyed headliner material.

Here’s the build on the pods. First, the stock pillar cover was cut to create the dip, and ring baffles with flush mount walls out of low heat plastic was aimed and secured:

Then t-shirt material was pulled across, resin applied, allowed to cure and then the pod was reinforced from the inside via a Duraglass/resin mixture.

Once that cured, they applied a couple of layers of filler and sanded the entire shape smooth.

Then to prevent any colors from showing through the headliner cover, SiS gave the two pillars a quick coat of tan paint.

Then they were wrapped with headliner material that had its foam backing removed. A big thanks to JAYINMI from SiS for his tip in using rubbing alcohol to soak the headliner!

Next a SEM dye was used to get the color closer to the factory match. It’s not perfect, but was the best the shop could find at the moment.

They went back into the car and the tweeters were installed.

 

The doors received a set of Morel Elate MW6 6.5” woofers. So new speaker wires were run into the door around the stock molexi plug.

Then sound proofing went onto the outer door skins (Blackhole tile) and inner door panel, STP CLD damper.

SiS fabricated a set of spacer baffles matching the shape of the OEM speaker and mounting holes, and coated each with a few layers of truck bedliner to protect them against the elements. The baffle was bolted in place via OEM hardware. Then the MW6 was installed.

Some STP damper also went onto the outer plastic door skin to help with resonance.

The same process was then repeated on the passenger side.
