These vids are great the most comprehensive I have found. I have 2010 A4 with the mid level audio (not B&O but have the sub and center midrange) Since factory amp is 2ohm output and 2 ohm speakers are hard to find can I take the high level input into a new amp and replace speakers with 4ohm

[@UltimateDIY]

Yes, you can do it that way.

[@technics6215]

So... I can take high level subwoofer singal from there, disconnect OEM subwoofer, connect it to something like JBL BassPro Nano (via hogh level input) and control it from MMI?

[@UltimateDIY]

Yup, that sounds about right.

[@MushypeasDMc]

Hi love your videos. I have the B&O stereo but the sub sucks is there anyway of making it better with out changing it in the green screen please

[@UltimateDIY]

Hi! Thaks! I would upgrade the speaker itself with a larger diameter one.

[@0franforn0]

Hi Ultimate DIY, I wanted to ask you for information that I can't find online and maybe you can help me. I wanted to know how the front tweeter in the dashboard is connected to the woofers in the door. I cannot find any connection cable diagrams online. You would be very useful with this indication to find the cable quickly. Thanks a lot in advance!!!

[@UltimateDIY]

Sorry, but I'm not sure about this. And it's also different between the base audio system and the higher end ones. As far as I know, for base audio the tweeters are in paralel to the big speakers in the doors. For the higher end systems, the dash speakers have separate channels.

Hello can someone help me with getting an rca signal for my Audi a4 b8 mine does not have anything in the left side its a storage cubby however I do have wires on the left side I want to get a rca signal but I don’t know from where

[@harvardmason3659]

What about adding an amp for a sub box that I add to the trunk?

[@UltimateDIY]

That is exactly whet the video explains.

[@nanysousa5630]

hello... i have the same system on my audi, and i wanted to connect the subwoofer, how could you help me?

[@UltimateDIY]

Hello. I did this: kzbin.info/www/bejne/gZbZpYdniZyhiZI

[@nanysousa5630]

I want to install the original audi subwoofer and I have it with me but I don't know how to install it

[@UltimateDIY]

You need to upgrade the radio unit in the trunk like I did and basically do about all I did in the video, but with a different speaker.

[@ahkrmusic3369]

Hi man! Where did you get clamps to connect those 4 new wires to get a clean subwoofer signal? Or which exact wires to I have to tap into to get signal for my aftermarket subwoofer? I have a 2010 A5 Coupe (non B&O) Thanks in advance

[@ahkrmusic3369]

Oh and my head unit just says Audi Multimedia (I have navigation) And I only have 1 wire running into that black thing you pulled out (you have a bunch of them in the video) next to the brown one you pulled out

[@UltimateDIY]

All I know about the wires and connections can be found in this video: kzbin.info/www/bejne/gZbZpYdniZyhiZI

[@0franforn0]

Thanks for your fantastic explanation. I have to ask you for advice, I don't have a unit that has SUB and center outputs, but only has FL, FR, RL and RR amplified outputs. Can I use these outputs and make them preamp so that I can connect them to an amplifier? Thanks you are a great...

[@UltimateDIY]

Hi. Welcome! Yes, but you need to add a high->low adapter.

[@0franforn0]

@@UltimateDIY Thank you for your help!!! The last question, my head unit is the model 4G1035053D, the wiring is the similar to yours unit but without center and sub? Thanks in advance :)

[@UltimateDIY]

I don't know the wiring for all of them. I always search it online to be sure. In theory it should be similar, but can't tell you for sure.

[@Mamelukefamily]

Hello, Just wanted to say thank you for the informative videos, I been watching them.and so far I've done the dash speakers, was a great help :) Wanted to ask, so when I cut into the speaker wires, the wires closest to the quad lock will go into my aftermarket amplifier (signal in) and then aftermarket amplifier (signal out) will go back into the factory wires towards the speakers? Essentially putting my amplifier between the Audi original wires?

[@UltimateDIY]

Hello. Thank you for watching my videos. About the wires question, basically yes :)

[@Mamelukefamily]

@@UltimateDIY top man, thank you so much :D

[@shibidi]

@@Mamelukefamily did this work for you? Im about to do the same but wondering how the dash speakers will go into the aftermarket amp since most aftermarket amps are 4 channel amps. I had the 3 dash speakers also.

[@Mamelukefamily]

@@shibidi I actually had the amplifier installed but the installer made a harness with a parrot kit. It hooked onto the harness from the amp and I retain all the functions. I'm using a 6 channel amp but 2 channels are for subs and the 4 are for door speakers

[@shibidi]

@@Mamelukefamily Oh nice, what about the center mid/high speakers?

[@ionutrobertt4641]

salut, aici as putea sa leg un subwoofer cu stație incorporata, mersi!

[@UltimateDIY]

Salut. Da, poti sa iei semnal de aici daca subwoofer-ul are intrare high level.

[@qasimhanif5485]

Hello I have same radio unit but don't have sounds in speakers if I change this radio unit I have to code this from Audi or it will work like plug and play?

[@UltimateDIY]

Hello. Sadly, it needs to be coded by Audi.

[@GamerJ3ff]

I dont have a Center speaker. But if i look at this vid that means i can put a center speaker in the car and put the cables in that center spot ? is it the same for audi A5 ?

[@UltimateDIY]

Only if your radio unit supports it. If you did not upgrade the radio unit, then it will not support it.

[@raminkh7552]

Hi I have a 2009 Audi A4 with the bang & plugs en upgraded system . I have static and small banging noise coming from only front speakers and the rear Sub in the rear deck In Your knowledge do you think my issue is the amp or the stereo head unit ( I know they are both in the trunk

[@UltimateDIY]

Hi. Honestly, I don't know. Could be any of them.

[@0franforn0]

Hello, sorry I have one question, the connector 3B7035447 is female, how is the part number for male connector? I watt to connect the wiring speaker without cut the line... thank in avance 😀

[@UltimateDIY]

Hello. Sorry, but I have no idea.

[@martinplumolessard4656]

is the signal inputing from head unit to the trunk amplifier is a high level? or can it be convert to rca connector on the new amp? nice video, thanks

[@UltimateDIY]

I don't know about the connection between the radio unit and the sub amplifier, as I don't have it.

[@SayHelloToTheRobots]

HI, it's not quite clear for me where it is better to take the high level signal from. I have a similar radio unit with oem sub plugged, but i wanna replace it with an aftermarket one. So can i take the signal from the sub wires or is it better to cut into the speaker wires? And where can i take the remote signal from? Thenks in advance.

[@UltimateDIY]

Hi. Depends on what you want. If you want the subwoofer control in the MMI to work, then you take the signal from the subwoofer. For the remote, I don't know.

[@TOLDyouSOagain]

Get a line output converter that has remote turn on built in

[@ceanionut4090]

Hello and thank you for video!! I have one problem maybe you can help me, since 1 month my sound is not working on radio, media or Bluetooth. Error on vcds is 000384 Optical databus , 011 Open circuit intermittent. I checked the fiber is ok, it's working 10 minutes than stops and so on.Any ideea? Thank you!!!

[@UltimateDIY]

Hello. Close to impossible to guess. But maibe you have a bad fiber optic connection. I know that internet fiber optic connectors can go bad because of heat sometimes. Maybe it's something similar.

[@tk421tt]

hi. is it possible to upgrade from lower model amp to this amp? or is there a way to tap into lower model amp to get pre-out?

[@UltimateDIY]

Yes, I actually upgraded mine.

Hi, i have a audi a4 2013 with B&O sound system, I want to install a aftermarket subwoofer, do i need a separate AMP for that?

[@UltimateDIY]

Hi. I would add a separate amp if you want more volume.

Salut Vreau sa montez și eu un subwoofer pe un a4 b8 2014 dar nu am ieșiri RCA. Vreau sa conectez un adaptor hi low și nu știu de unde este mai bine sa îl leg, pentru un sunet mai ok. În spatele masinii la unitatea audio sau în în spatele playerului din bord? Mulțumesc

hi. can you make a video when you have time for this car. how we can connect a subwoofer on a aftermarket amplifier.

Hi. Sadly no, as I don't have any audio upgrade plans.

[@arvisuals8803]

if i directly cut the wires to connect to an amp , does it have to be bass amp or voice amp ?

[@arvisuals8803]

and will i still control my music from the center console

[@UltimateDIY]

You need an amp that has a high level input or you need a high->low adapter.

[@sliceoflife7057]

Salut , m-am conectat cu hig low adaptor la amplificatorul mașinii , in schimb amplificatorul instalat de mine stă în protect plus de asta navigația se aprinde doar pentru câteva secunde , ai idee unde am greșit dacă nu cumva am omis vreun detaliu , Mersi .

I have an MMI 3G Hight, and the unit is missing in hte trunk ?
