Thanks for showing how you took the trim off. Been wanting to upgrade mine, and haven't done it mostly cuz i didnt want to screw up the trim. But now that I see how easy it is, I just installed mine and it sounds great. Thanks again!

Jason, thank you so much for this video. The 8V platform is very, very similar (as far as the interior/stereo go) to my B8 A4 with the B&O audio. This video is incredibly helpful because I'm planning on doing something similar to what you've done here. Rock on!

I don't know how i got here, but man i could watch these kind of videos all days! Just a super nice video! And the install of the amp looks amazing!

that's a really nice and clean installation just the box for the sub and that's all

Really nice to see the way you handle things. Professional style, factory look: superb. Good luck with the project. I will keep following your channel.

really great in depth review. Love your car man!

Always nice to see people using Hertz products, great stuff from those guys. Really under-hyped... When I was working at a car audio shop the dealer for Hertz / Audison was great and the dealer comps / prices / comissions on them is insane!

Very informative. Thank you. Much appreciated, when someone goes above and beyond to explain everything.

Great video, I like how thorough you are with everything.

This video REALLY HELPED ME. Did something very similar in my A3. Thanks a lot!!!!

Very informative and clean install. I have a 16 A3 and looking for more bass as well. This will help a lot.

I am of the opinion the stock B & O subwoofer is great. Whatever works for you is great.

Nice video finally with how to remove some of the panels and install! So many not A8 o B & O systems! Thanks

Hey man! Awesome video! Very informative! Nice bits of extra key information in there too!

This is crazy I've been into your store a thousand times since I was a kid and KZfaq randomly suggested this video lol. I just ordered a 2017 Sepang Blue S3 last week. Good to see you're still doing well and that you've upgraded from your old yellow Mazda wagon. Where did you get the APR Tune done? Looks like places to get it done in STL are pretty sparse. Videos are great keep up the good work. Cheers from up the street.

thanks for taking the time and effort to show this

Great video man. I love how u used the stock location and how u sound proofed the firewall & trunk area s. Where u located at and would u b interested in doing this again to my car lol. Love your attention to detail and professionalism there aren't many people left like u in the car world ne more. Who like doing things out of passion just $ hungry people looking to do a hack job as fast as they can with as little effort possible. I love my car so much I wouldn't just let ne work on it. Keep the videos coming man great video

easily the best video to help me put an amp and a 10 in my girl's 8V. Thanks so much!

Very informative video. Thank you. Cant wait for another. Clean install!

please make more videos on the audio upgrades. for amp upgrades into this car look into the audison integration stuff. audison bit one and audison bit DMI

Looks great bro, I dig it .

This video is extremely helpful - I'm upgrading the subwoofer on my '16 A3 non B&O (10-speaker)! I appreciate you posting this. I may have missed it but what did you end up tapping into for the remote on for the amp?

Man thats awesome. I am sooo thinking of doing this setup. But on the new RS3 im getting

Liked and following, traded my '16 stage 3 gti for a stock premium 15 audi a3 because the a3 has Quattro. I've been trying to find the love with the a3, truth be told I've got kids and the gti was cramped, this is a daily driver for the snow which is why it's important to me. I'm going from the hot asphalt of florida to up north, that's why the all wheel drive was important. Sorry for the word wall but Audi is such a specifit niche and most people go the VW route. Any thoughts are welcomed and yours is very clean. I'm redoing my audio system and say your video. Good stuff and I hope you and are well

Hi, Any idea or picture of how to pass the positive battery cable to the amplifier? Thanks

I would like to do this too. But already have problems fitting my golf bag in the trunk, and is this not gonna help on that.

Looks like a mountain biker right there! I bought my A3 for mountain bike road trips. Why mount the sub on the rear right corner as many have done ? Figuring out the setup i want to go with.

Nice setup, do you have to get a enclosure for this? Much much better is it?

how do i get the airbag tags off they’re like tight as glue to the thing rear pillars

Great video man.

Did you ever do the enclosure??

Great video! Thumbs up from me.. I’m planning on upgrading my ‘pancake sub’ but I’m not confident with changing the amp... how do you think the Stock amp will fair up with a just a straight Sub swap? Thank you

Very descriptive and helpful, unfortunately I can't go through the clutch hole because I have a clutch in my S4😂😂

salve anche io o la stessa macchina vorrei capire il segnale audio l'ai preso dai fili del sub è in stereo o in mono...

Awesome job!

@ 0:55 what kind of adapter/ signal cable did you use to use the original subwoofer controls in the head unit?

What size are the small rear deck speakers? 3 1/2inch?

I'm a rookie with car audio. Seeking some help. I salvaged B&o speaker 16 speaker set out of a 2019 audi a4 (only speakers not the amp) I'm planning on installing the complete speaker set in a classic project car. How/what amp do I choose or what else do I need to complete it. I have a kenwood head unit.

I think it would be better just to do a slim 10" box. This car is not that large. Ill try to use the factory sub wires to pull the new wiring thru. I'm doing a lot of research. I wish i could just attach those wires on the stock sub to an amp. And just route the power wire.

Hello! The factory sub portion is confusing me. Negative one and two go to negative on a line out converter and vise versa? Amp turns on and shuts off as it should, loud "THUMP" when turning off or turning on car, but no bass signal heard.. I realize this video is 7 years old at this point it I can't find an accurate post about this exact car and stereo.

Great video!!!

you should definitely upgrade your speakers now. aftermarket speakers compared to factory speakers audio quality is night and day.

Do u know where the factory amp on the 2015 is located

Hi.. nice video. I just bought a new 2017 s3 with b&o sound. I am impressed with the speakers but the woofer grill rattles at loud bass! I am not sure if b&o woofer is disappointing or i messed up any settings. Have you had similar experience with b&o ? What about hertz?

thanks for this.

How do the bottom pcs. That run along the carpet get removed? Doing my meth kit this weekend and need to run to engine bay

Buy an ap 8.9 bit too, you really need this trust me

I have a MY2019 S3 and I can't lift that airbag bit out, it seems sealed in there. Tried knives and thin flathead screwdrivers, it won't budge..

From where you take the remote for the amp ?

Where is the actual AMPLIFIER in this vehicle? I need help.

Ok so I have an amp and subwoofer I just need the negative and positive sound input to put it into the amplifier. Did you take it directly from the OEM subwoofer?

Nice car. I've been looking at getting an S3 but since I have attachments to my current cars - I'd be turning my driveway into a parking lot....but I want a parking lot =). Anyway, nice car, nice video! I bet that sub adds a ton of extra bass.

How many watts are the original subwoofer? I bought a blaupunkt audi A3 subwoofer online but i can t find how many watts

Jason, did you measure the signal going to the B&O sub? I'm wondering if there are both high and low pass filters on the signal since the subwoofer is so small and enclosureless/infinite baffle?

Jason, going to try this this weekend in my 2017 A3 with B&O. Rant first: I'm upset that Audi removed the sub controls in the 2017 with the new MMI system. The sub is very weak and I have no control over it. I'm also concerned about the Active Noise Canceling system. Will that have to be disabled? Did you do that? How? Do you have any more detail on how you mounted the shelf you mounted the Sub in? Thanks! Erik.

Hiya mate, not sure if you still answer questions on this but hoping you can as so hard to get info about the bang Olufsen as no one goes in to detail like you did adding stuff, basically i have the exact same car in black also with same system, i want to tap in to the 2 rear parcel shelf speakers with a kicker kisloc 2 however im worried as dont want to waste my money as im not sure if it will take a good signal from those speakers as i believe they are surround speakers so wont provide a full range good signal to send to my active sub? Id love to hear your opinion on that, the second option i have is tapping in to the factory b&o sub wiring however im not sure the kisloc can handle that as the b&0 has got to be pushing out at least 200w and i believe the kisloc is rated to 55w and dont want the hasstle of an lc2i as they are too complicated for me, im still planning to leave the b&o sub running as is and the goal is to fit an audison prima 10inch active sub to work alongside the b&o to give it that extra punch, i had the audison fitted in my golf r and was connected to the rear speakers on the basic 4 speaker factory system and sounded great but the b&o is much more complicated in speakers bloody every where doing various things😂🙈.. Hoping you can give some advice dude, your video is literally the only help on the internet and iv been researching about a week lol..

what did you use as a remote turn-on for the amp?

woww those mountain bike

Damn

No Capacitor ???

Where is the stock bang and Olufsen subwoofer located?

My B&O sub just blew. I only want to replace that sub. Is there anything that is plug and play? or do i need to get the OEM sub?

Does anyone have details on the wiring for the stock non BO system? My amp already has a built in LOC and can accept High Level inputs so I was wondering where I should be tapping the speaker wires? and if I should be tapping the oem subwoofer signals or the signals going to the rear door speakers. Also, is the OEM non BO amp on the left side of the trunk when you are facing the trunk?

MID LIFE CRISIS!!!

No sir it really is 540 watts RMS, and do you already know that you do not need a line level converter?

What was the actual name of the device you used to convert the factory sub output?

Why would you use an LOC when the Audison amp already accepts both low level and high level inputs? In other words, the LOC is completely unnecessary. Nice car btw.

Where did you get your roof rack??

Are you going to upgrade your door speakers?

After spending $500-600 on different Hertz Speaker, I was really disappointed. I had everything sound deadened my doors and Hat Rack, Trunk ect.. I pulled everything out and put cheap Kicker speakers in that I bought at Walmart. Because I sold the car, Believe it or not, they sound way better. My next Audio build is gonna be something special. I went to some SQ competition to hear some things in person and not just go with brand names cause not every brand name lives up to their name. Where the Kickers better? Maybe not but it had a bunch of better mid bass and for the price it was hard to badmouth them. If I’m gonna down $1000+ on speakers, go to some SQ competition and hear them for your self cause local shops will push Focal Utopia when there are better speakers out there for less or a bit more. Love the Audi Build, I have a 14’ A6 with Bose and I’m just gonna add bass to that car, so thanks for the Video!

Does your car have the rear airbags?

I post some follow up on VW Vortex forum if you want to see box i built and some more info. forums.vwvortex.com/showthread.php?8244025-Upgrade-Sub-in-my-Audi-S3-B-amp-O-system-Hertz-sub-and-Audison-amp-video-walk-through

If someone was doing this work for me how much I expect to pay them

B&O 10 inch sub a cheap pancake sub ????????? Some people surely don't know what B&O represents in the high-end sound and video. I assume It's just a matter of lack of information.

And there goes your warranty....
