Audi a3/4 concert stereo adapter. 

I would love to see you doing this from the beginning. I’m new to this stuff and am way too confused to know how to set it up like you have done here

Hi a have audi A4 b7 with Bose system i got a after Market stereo but there is no audio at all i have only front 2 spakers a subwoofer and amplifier please help me im stuck for so many days

Ideal mate, I've been hunting for something like this as I completely at a loss to get my rear speakers to work. I'll try this later today. 🤞🏻 🙏🏻

Thanks mate

My Aydi got 4 channels amplified, what next?

Hey man if you can help i have a wiring harness for my a3 but i cant get the back speakers to work i think the amp is not turning on how do i fix this ?

My sub works now but rear speakers still don't work

Iv got an audi 1.9 tdi 2005 try to hook up my pioneer radio but haveing problems. That red wire were is that going

Just wired this in, wanted to double check; will it drain the battery?

Hello. I did the same and the rear speakers play very low.. I have the same adapter

Is this setup for a half amplified or a full bose amplified stereo as I'm having trouble with my amplified bose system

So i just installed a Pioneer headunit in mine aswell as a subwoofer in the boot. I got the subwoofer working with just connecting the rca´s and the remote to the blue/white cable from the headunit. Only issue i have is the rear speakers which are not turning on. Do i still need to connect a red wire like in the video for them to work? I just dont get why the amp for the sub turns on but not for the rear speakers..

Where can I buy the adapter you used for the bosse amplifier?

My aftermarket stereo wont turn on at all when I plugged it in. Do I have to take a seperate wire from the ignition on to the red one from the stereo just like you did? In that case, from where should i connect the new wire? Somewhere in the engine or somewhere else?

Where did u run ur ignition live from exactly please

I would’ve just connected blue yellow and red. Why jump them? Extra steps for no reason

How do I know if my car is half or fully amplified. I have the symphony stereo
