Has anyone added a subwoofer or amplifier to their 8v?

I have a 2017 A3 Sedan/Saloon which came with *** and no subwoofer control. The sound was very boring and flat. I got tired of waiting for Audi to update the MMI firmware to give me control of the subwoofer so I picked up a Pioneer TS-SW2002D2 subwoofer and an amp with speaker-level (high-level) inputs and a remote bass control. I just used the existing wires from the factory sub.

Its probably not the most powerful subwoofer in town but WOW what a difference it made. Trunk space is a priority for me so I wanted a shallow-mount sub which would work in a free-air/IB setup (meaning, not in a box). I would probably be happier with the sound if I had a beefier sub in a box but it sounds pretty darn good as is, and it only sticks down about 1 inch below the rear deck so it doesn't eat up my trunk space.

I'd be very interested in a part number for the Parrot loom mentioned above. I've searched around and haven't been able to find it. I guess the Audison one should work also, so thanks for that link! I've got some quite nice Focal
speakers along with an amp/DSP combo for the doors that I was planning to put in at the same time as my sub install, but the sub by itself has made such an improvement that upgrading the rest has become less of a priority.

If anyone is considering going the same route I did, I'd be happy to share more details about my setup, as this was very much a learning experience for me.

Hey there. I am trying to retrofit Audi SS to my stock entry system. My vehicle is 17' A3 FL Sedan, same as yours. I assembled the center mid, and also purchased front speakers and waiting for them to ship. However I suppose I should skip the oem subwoofer and put a different one like you did. My question is does pioneer 8" sit to the oem hole under the rear parcel? Where did you put it in your vehicle? Also what amp have you used? Cheers.

Audi

*** = Audi Sound System ! Of course, it's obvious. No wonder Bletchley Park turned me down.

Then I tried to use it's abbreviation and got to the bottom of the reason.

OK now I understand the parlance I too am looking at adding the *** to my FL A3 MY 2017.

@DJAlix I will send you a note to your business e-mail to discuss.

Hello. I used two 8" MDF rings to mount the subwoofer to the rear deck. I first covered the entire rear deck in a layer of sound-deadening material (like dynamat, but a less expensive alternative). Then I attached the subwoofer to the MDF rings using screws, and drilled up from the bottom into the MDF and used a couple more screws to fasten the whole thing down. So under the cover, my rear shelf looks something like this now (only I used MDF rings from ebay/amazon, not custom cut boards like this person did):

My amp is a Kicker CX300.1 which I got on ebay for $50. It works perfectly with my sub, the only small issue is, apparently Kicker amps don't play well with Auto Start/Stop systems, so when my car restarts itself after stopping for a red light, the subwoofer stops working for a couple seconds. Not a huge problem, and I can get around it by disabling Auto Start/Stop. I've heard that other manufacturer's amps don't have this problem.

I know this is an older thread but I have a question regarding the active noise cancellation when installing an aftermarket subwoofer. I have connected many systems In the past but have never had an issue like I am experiencing with my 2017 s3. Everything works perfectly until I turn my car off. When I turn the car off the subwoofer creates a lot off bass from some type of tone until I either open the trunk or hit the analog power button on the center console. It also randomly goes off after I have locked the car and have gone inside. I have a Lc2i hi/low convertor getting signal from the rear subwoofer to a single amplifier/subwoofer. Any help with this issue would be greatly appreciated, thanks!!

Thats awesome Alix, good to talk to someone who has good experience too! I myself have been in the audio game for the last 20 or so years and have built some of the most insane audio vehicles in the UK...its my hobby and also my profession luckily

Thats my fear, from what I can gather, the stock Audi system does filter to some extent...but listening to some of my usual music, it seems to play most if not all the frequencies through the stock speakers...which is making me wonder if the original base spec stereo (which I believe has no external amplification or processing), does give more of a full range signal than any of the higher specc'd units (unless we are talking fibre of course)

Looking around the boot for external amplification etc, there isnt anything I can find (although I havent looked too deep to be honest), and the headunit doesnt have any output setting for subwoofer etc...hence I have always believed its a basic setup in there at the moment...albeit, it does sound very good for stock! To know whether ours has fiber output, is it a matter of having to remove the brain in the glovebox and looking behind there?

One BIG annoyance I have with the stock system is the volume limits...which is another reason I want to get cracking with my audio build lol

Not sure if you have ever looked into it much, but I have heard instances where people have used the MoBridge units to get an optical input, have lost their bluetooth mics?

Hi Teamspb, did you manage to get a full range output from the headunit or optical out ? if not what method did you use to send signal to amp ?

Alix, if my unit has optical out, does this has to be activated ? and with this can I still use the on screen controls ?

I have gone the optical path for one year now, using this:

https://navtv.com/products/NTV-KIT860/zen-v.html

MMI->Most150 optical to Navtv Zen-V-> TosLink optical to Audison AP 4.9 bit

Apart from the fact that the sound is crystal clear (with good speakers and sound deadening), I finally managed to skip the fragile internal amp of the MMI.

Expensive interface, but worth every penny.

P.S. Yes, MOST output activation needs coding via VCDS, but a relatively easy one.

BillyGiann thanks for the reply,
wow this seems like the best solution sound quality wise, it is a little expensive but I bet it's worth it.
Care to share more info on your setup?
I'm aiming the change the speakers to component mids and tweeters and a sub in the trunk but like to reuse the factory speaker wiring.

Retrofitting the Audi Sound System Sub, and centre, is one of my most popular retrofits at a rate of 2 to 3 a week. Totally OEM with no splicing as all factory parts are used.

The internal amps on the basic MMI units can have their additional outputs activated and an additional tone control added in order to connect 3rd party items also, again no need for splicing.

hi if i send you a message, could you quote me to have this done to my 66plate a3 Saloon. Thanks

Hi All, sorry to revive an old thread... I was wondering if it's a matter of plug and play with the sub unit for the audi sound system? I got a replacement MMI MIB1 that has the sub volume coded already (as I can tell the main speakers now don't have as much deep base). I've seen one on eBay (part number 8V0035382D), but wasn't sure what else I need!

TIA

I think the sub only fits in to a 19” spare wheel on a hatchback. So you might need one if yours is an 18” spare.
