Hello everyone, I am entering the final stages of my build so I figured I would start putting some pics of the journey on here. Those us that own Audi's know how bad the stock sound system is in our cars. With the exception of subterFuse's incredible build in his S6, there aren't many documented builds out there in the Audi community, especially ones that upgrade the standard (non Bose/B&O) sound system. My hope here is that I eventually help someone else upgrade the system in their car. So on to the build...

My 3 main objectives are to

1) Build a decent SQ system (i have no intentions to ever compete) that I can enjoy, as this is my daily driver
2) Keep the car totally stock looking to the casual observer
3) Do this entire install myself and learn a little something in the process. I have done some decent systems in the past but never on a high end car like this.

So here is the car

A well welcome to a fellow Jersey person and also as a lover of Audi. Looking forward to hearing / seeing your thoughts as they play out. :)

I bought the car new last summer and within a month or 2 I had realized that the car had abysmal bass.

Mostly because of this cheesy stock sub enclosure in the spare tire compartment. You know its bad when the sub has a 6" driver and is mounted in a plastic box in the spare compartment!



I decided to do a quick upgrade , knowing that winter was coming and I probably wouldn't have time to do a full system upgrade. So after going through the various Audi forums I saw that many owners were just tapping into the rear signal, using a LOC and adding a box in the hatch area.

I decided that this would hold me over until spring so I bought an Audiocontrol LC2i , a JL Audio XD300/1 mono amp and a JL Powerwedge with a 10' TW3 driver in it.

I made myself a carpeted shelf for the amp and mounted it on top of the stock radio bracket. This is where the Bose or B&O amp would actually go if I had that option. I mounted the LC2i in the space between the radio and the new shelf. With the battery being in the trunk it was easy to add a properly fused power lead from the battery.



This was OK as a quick fix as I was still all stock and could control the sub controls from the stock MMI head. Until now.......

So over the winter I researched my options and I came up with this as a hardware list

Amp - Mosconi D2 80.6 DSP
80w x 6ch plus a full 6to8 dsp. All in a package small enough to fit on my little shelf. This will allow me to run a 2 way active setup in the front and a set of components, passive, in the rear. I know not everyone is a fan of rear fill but remember, I don't plan to compete and I do promise to follow the Rear Fill Best Practices mentioned elsewhere in this forum :D

This will also allow me to send a processed signal via pre out to my JL Audio amp that I will maintain for my sub amp to drive my JL Powerwedge.

Pre Amp/MOST Bus Interface - Audison Bit DMI
So I originally tried to buy a mObridge DA1 but no one in northern NJ could find one of these. As luck would have it, another member on here (JimmyDee) was nice enough to sell me an older version that works perfectly. In all of the craziness of ordering gear, wires, tools, etc. I actually forgot that I had ordered the Audison from a dealer about 2 months earlier. I actually had the mObridge installed, working beautifully, in the car when the dealer called to tell me to come pick up my Bit DMI. This is ok, my son is planning a build for his BMW, that also uses MOST, so we will use it there.

So I have no pictures of any sound deadening in the doors because I did that back in the fall to help the stock speakers right around the same time that I installed my sub upgrade. It was a good layer of dynamat inside the doors and on the outside of the door, internal to the car I used Cascade Audio's VB-2 as a moulded layer between the metal of the door and the door card. You will see it in some pictures of the front doors, but this stuff is pretty cool, using a heat gun it moulds right to the contours of the door and is very thin. The stock sound deadening on the door card was pretty good so I left it alone.

With all of that said lets run some speaker wire.

But first lets color code it with some Techflex

Make sure its all labeled up right


There are some nice generous spaces to run wires in the Audi. An added plus is not worrying about crossing signal wires and power wires since everything is in the back of the car.



I basically ran them right next to where the stock wires are and used most of the cable management that is already in the car.

This is really cool, thanks for sharing.

I plan to purchase an A7 sometime in the future, and of course while day dreaming about it I question what I will do for audio. Not many build threads out there for the A7 so it's nice to see this.

Of course nothing is never easy..I ran into these Molex plugs in the front doors, the rear doors were easier because I actually was able to move one of the pins. I drilled out( carefully :eek:) both sides of the plugs with the Dremel using a bit that looks like something a dentist would use. It does a tiny bit at a time and I was very careful and sloooow using it.
A big thank goes out to Octave, who did subterFuse's install, for giving me the idea and courage to go this route, like he did on that S6.


It was sung but I got it through on both ends

Its a great car. If I could do it again , I might have gone Diesel, the specs on it are crazy good.
Save your money on the audio options they are all crap. Wait until you see the stock drivers....a magnet the size of a silver dollar on an 8" driver :furious: in a $75k Base model car?

So on to the speakers. Again I want looking to build a sound competition car so I went with modest but decent components sets for the front and rear

In the rear I went with a set of Focal AS130's, its a 5.25" driver. I will run these passive using the supplied crossover and 2 channels from the Mosconi amp.


Tweeter fit right into the door card and looks good

Did a fair amount of deadening inside and out on the rear doors. Note...I had to move the crossover from the location that you see in the picture. This a pic of the left door and I was getting this weird static out of the tweeter whenever I would start the car. I moved it to the left of that sensor that you see in the "pocket" that has the yellow wire coming out of it.

Finished door...lines up pretty good

On to the front stage

I picked up a set of the Focal PS165 components. I will run these active using 4ch on the Mosconi amp

Front door...the CAE VB-2 is a really nice sound deadening option and it moulds to the door nicely.


I added some Dynamat on the bottom plastic section to the right of the driver, e VB-2 would not stick to the plastic. Obviously I repeated this on the left side


So this is the part that I wasnt most proud of. Its the only non- stock looking part of the install. I didnt just want to drop the tweeters into the stock dash locations. I want to keep the tweets on axis and the Focals came with a surface mount option. They dont look terrible but short of building custom pillars, it was the best I could do. All I did was drill a few small holes in the stock grilles and mount secure with a small screw/bolt combo. I also have a spare set of Audi grilles just in case I screwed up:cool:

Nice work. Great to see someone with the nuts to pull apart a new Audi. What are the sub plans.

Funny that you ask that.. if you remember back in the beginning of this thread I had a JL Audio power wedge box with a 10" JL sub in it. Dont get me wrong it sounds good but I had the opportunity to get one of these and I just couldnt pass it up......



Just a little tease for now, But we will get to the sub later...lets install the guts to make this thing go!

Ok lets talk about some hardware
This little guy will provide 6 channels of Class D power..80 Watts to be exact..and it has a 6to8 DSP built in as well. It is small

Really small

Its a well made piece of equipment

I bought the bluetooth module to tune and it also allows you to controll it with an Android or Apple device. I also bought the RCD as well.
