Meet the gorgeous Audi A7 Prestige Trim. Hello black beauty. The Audi is sweet, but there was one big problem. The bass from the speaker Bose surround sound system is pathetic. Completely unworthy of such an amazing car. Despite boasting a channel amplifier with over watts of total power, the bass is anemic.
So I set out to remedy the situation. Subwoofer spec sheet. The vinyl covering on the box needed to be replaced, and this time I decided to use regular speaker carpet. I watched a few YouTube videos to brush up on the technique. My only complaint is that it is pretty thin. It was advertised as having a latex backing, but it stretched a bit too easily as I was cutting, even with brand new utility blades. Because I wanted to make my subwoofer box both easily removable and securely mounted, I attached two large eye screws to the back of the box.
Along with some industrial strength velcro, I used the eye screws with a short cable lock to secure the box to the luggage hooks in the hatch of the car. I clamped the cable lock together using a rock climbing carabiner. This avoided having to screw directly into the sheet metal of the car.

Last, I looked around for a stylish, high-excursion speaker grill to cover the Alpine sub. At first I used a regular beehive-like grill. But, with the new Alpine amp, the sub actually hit against the grill as it oscillated. I was tempted to leave the sub uncovered, but that seemed a bit too risky as I do haul around my bass gear and other cargo regularly. The grill looks great, but I wish it was metal instead of plastic. Overall, it seemed a great fit.
I also got the Remote Bass Level Control Knob so that I could adjust the overall output level of the amp from a more accessible location. Adding an amplifier and sub to the existing factory system meant that I need to tap the powered speaker level lines. Not only is the LC2I a crisp and clear active line out converter, but it had two other features that I thought were going to make my life easier more on that later : GTO Signal Sensing, which will turn the unit on when it detects signal from the speaker inputs, and a output remote turn on lead which can be used to switch on your amplifier.
One of my requirements for this installation was that the subwoofer itself had to be removable. I described my approach to secure, but easy to remove mounting above.
The wiring needed a similar approach. To accomplish this, I built a small box to house a speaker terminal cupremote volume level for the amppower distribution block for the lightsand an overall master switch for the add-on system leaving the factory system in place.HOW TO: Install Subwoofer w/ Factory Radio
I also added a small blue light that was laying around. Removing the sub just requires unplugging the speaker wire banana plugsunplugging the lighting wire leads for the lights inside the sub box and the one on this little boxturning off the master power switch, and then unhooking the carabiner on the cable lock wire.
Installation Installing the audio components and wiring in the hatch of the A7 was pretty straightforward, but not without some issues.
Because the battery is located in the spare tire well, it was super simple to attach a thick power cable and run it into a power distribution block. From there, I ran constant power leads to the amplifier and the LC2i.
Likewise, there were plenty of ground mounting points to tap into as well. Getting the audio signal from the factory subwoofer was very easy. I simply spliced and soldered another speaker wire lead into the line near the connector that goes into the factory subwoofer housing. This line was the input going into the LC2i.Remember me.

After few hours of work i finished my first sub-woofer installation project, few weeks ago i was clueless what i needed to buy but after extensive research i taught myself everything i need to know.
First you need a sub: I bought two Pioneer TSWD4 because few months back i had one in my S4 and it worked great, even with the stock amp. Second you will need an amplifier duh. I dint know that at first but yes, you need one because OEM amplifier sucks.
I went with Pioneer GM-D because of three reasons: 1. The amp was cheap : 2. More resistance means less output to your sub woofer.The Audi A6 is a good mid-sized sedan for a premium audio upgrade. The car has a total of between 9 to 19 speaker slots depending on variant which are evenly distributed and staged high up on the dashboard, mainly in front to give the driver and co-passenger a rich and clear music experience.
Being positioned in appropriate slots and tuned to deliver crisp and clear audio response to the cabin occupants. Though this audio setup sounds quite balanced, it lacks head room at higher volumes. AUDI have installed large 6.
The problem actually lies in the actual build of the speakers and OE amplifier, which are purpose built and are meant to sound average to the experienced listener or music lover. Due to the mid-sized build and overall cabin volume, the A6 does not need very powerful speakers in order to produce a clear and balanced music experience.
The doors are built quite strong and often sealed off with a plastic cladding or aluminum cladding which produces strong bass response compared to other cars in the same category. In order to get the right amount of detail, placement of speakers and especially tweeters is very vital in any car. Almost all AUDI cars suffer plastic creaking and degradation on Indian roads due to the poor condition of the road surfaces, pockmarked with pot holes and ridges.
Though this problem can be addressed with damping and soundproofing, some minor creaks here and there crop up in some AUDIs. The rear parcel shelf inside which the factory fitted subwoofer is mounted jarrs at higher volumes, though it can be rectified with some damping and sound proofing.
The cleanest method of upgrading the audio on an Audi A6 is to follow the least invasive cabling method in pre designated routes provided by the car manufacturer. The next step is to select sets of speakers and matching amplifier s staying well within the provided space in the car, which in case of an A6 is medium amount of clearance. The final speaker configuration is a front 2Way or 3Way setup Mid-range speakers and Mid-bass speakers in doors, tweeters in the A pillars and Rear 2Way Tweeter and Mid-range speakers in doors speaker setup.
All of this has to be powered by amplifiers with matching power and sound signatures. Now, this variant of the A6 already has a good sounding setup and upgrades are usually partial. The installation is similar to the Bose audio variants, but the analysis and tuning of the audio takes some time and patience in order to achieve a perfect balanced sound.
Pros : Due to the mid-sized build and overall cabin volume, the A6 does not need very powerful speakers in order to produce a clear and balanced music experience. Cons : Almost all AUDI cars suffer plastic creaking and degradation on Indian roads due to the poor condition of the road surfaces, pockmarked with pot holes and ridges.

A6 C7 Subwoofer install help with Bose Guest-only advertisement. Register or Log In now! I have a A6 Prestige with the Bose system. I removed the factory Bose sub from the rear deck a few days before the install to allow more sound into the cabin. When the shop tried to pull the signal from the factory sub harness, they said there was no signal. They ended up pulling the signal from the front door speakers, if I understood the guy right.
My issue is that with all the different audio sources CD, XM radio, Bluetooth and FMI get different bass levels from each and different levels from the same source with different songs.

I know that some songs will be more bass heavy than others, but when I listen to country and I can't even hear the bass on one song and the next song I can, it's frustrating. Same thing if I listen to rap or metal. I'm not sure what LOC they used, but is that my problem or is it that they took the signal from the door speakers?
Thanks for any help or advice you have. Black A6 Prestige Quattro. Injen CAI. TSW Luco 20x9 wheels.I have finally made it up to the Audi A6. I love the car, but the Bose sound system is not quite what I was looking for. I did not have the time or energy to do this myself now that I have 2 young ones, so I shopped around for a custom stereo shop that would cut no corners and had a passion for what they did.
Charles Maddy is the owner, has been around for 23 years, and does impeccable work. His lead installer on my car was Mike R. Now I will say that if you are price shopping to find the best deal on components or an install, stop reading. This post is not for you.
It seemed like my car was the most mundane in that shop considering the others were Bentley, Ferrari, and Porsche. Mike R.
Mike does, and does well. His meticulous attention to detail guarantees that everything fits perfectly, works perfectly, sounds great, and will not break. I keep my cars for at least 10 years each, so I needed all the top quality install techniques like soldering rather than crimping, running wire loom rather than just zip-tying along, running wires along factory pathways instead of haphazardly, etc.
But Charles and Mike never felt challenged or threatened — they were interested excited even to work with me and bring my ideas to reality. Stereo tuned such that with only minimal subwoofer gain adjustments, it will faithfully reproduce all genres of music from rock to vocals to rap to electronica.
Other shops recommended I place them all low to the ground in the last rung of the grill easier install, but WRONG thing to do. Anyone who studies up on laser jammers knows you stealth the car, not the install.
BACK — due to the silver car, the rear detectors are pretty easy to spot if you are looking for them, but otherwise seated nicely. They sit just a few millimeters under the trunk lip. Both Bel and Blinder units will mute the factory radio when they alert.
I will eventually have the guys locate a second speaker there to accommodate the Blinder voice alerts. Kudos to Mike installer extraordinaire who took it upon himself to do this since he felt it would have made the install better. Mike built a custom bracket and locked it onto the bottom of the gear shift boot. All functions of the gear selector still work without any compromise even the tiptronic action. The Bose speakers and enclosures were all removed and new custom molded plates were made utilizing all factory bolt patterns so that the original equipment could be thrown back in down the road in case I decided to remove it when selling the car.
The components are made of thick plastic that was heat molded to fit perfectly, and last forever — any wood-based enclosure would have eventually rotted and been ruined by the damp climate here in the Pacific NW.
This really fills in a cleanly blended front stage with matching sonic qualities between the doors and center. The factory Bose amp bracket was removed, and Mike again, working on his own accord to make sure the install was impeccable custom built a beautiful set of brackets to accommodate all the new components along with the original Bose components, and not take up ONE INCH of my trunk, nor cut one hole in the factory panels.
It was just amazing workmanship to deliver my impossible request of leaving this daily driver fully usable, and demanding it have a stellar soundstage.
The system was tuned to have flat response across the entire spectrum and center stage was time aligned to be in front of the driver, not the center of the car.
Also, the DSP only runs the front sound stage and the sub. Otherwise, the rear channels are still run by the factory Bose. I saw no need to spend more money on the rear passengers.Wippers Apr 19, Log in or Sign up.
Can you eak any more out of it? WippersApr 19, Yes I've played around with what settings are available but disappointed with the sound. I like a decent amount of bass and some tracks sound fine but they are the ones I used to have to turn the bass down in the A6. Therefore I know the system can punch out the bass I want but it's as if I need about another notches.
WippersApr 20, Bulldog likes this. Nobody else had this issue with the Bose system? WippersApr 23, AdamZAJun 13, The standard system on mine has subwoofer and Gala controls. Not bad though, I'd expected much worse! StatlerJun 16, I've looked into putting a better sub in the boot but it's an expensive option as I think the Bose system can be a bit of a pain to plumb into. Also looked to replace the front door speakers but just too expensive. Sent from my iPhone using Tapatalk.Daniel-be May 22, Log in or Sign up.
At Bose system - Where's the bass?
Cookies Snack. I was wondering where I could find the audio amplifier in a6 c7 avant? In previous a6 c6 stock amp was placed in the trunk at the left side,now in that place I see only empty space. I've got a basic audio factory setup, non-bose but with plastic subwoofer box next to battery in the trunk. Daniel-beMay 22, Are you looking to upgrade the amplifier? Mine's the same but I thought it was bose on the sline a6?
Doesn't matter if it isn't like it still sounds great. Daniel-be likes this.
Yes indeed. As long as there is no amp in the trunk box at the left side I don't think that this is a bose system. So what I have is a active subwoofer box - I would like to get rid of that one and put another woofer with external amp.
I had such an upgrade done in my previous a6 c6. The thing is that in c7 I cannot find any amp installed - so I was wondering how the speakers are powered? It looks like the sub box has a small amp inside,but the rest of the speakers. Anyway it's not that important as long as I can find a place,where I could tap in to get a speaker signal - to connect high-low converter.
Could I tap into the wires,which come into the sub-box? How to check either they are speaker or power wires? There are only two wires going into that sub box. And if you take it out of the car, it is very light. Most likely a passive sub driven by the MMI system. You just need to use a multimeter on the two wires. HingyMay 24, Daniel-be and Jakes like this.
