This information could be helpful for those like me who have a DSP Sound System and want to install a new car stereo.

Normally the aftermarket Car Stereo Units aren't able to send the right commands to the can-bus in order activate the external amplifier.

For this reason there are some companies selling expensive can-bus adapters able to do this.

But if you follow this procedure it is not necessary.

1) disconnect the old Head Unit

2) disconnect the battery for at least 20 minutes (just the minus pole is enough)

3) connect the new Head Unit

4) connect the battery

After this the DSP Amplifier goes in a special mode were is switched on by the key-on can-bus message and switched off by the key-off can-bus message and doesn’t need the activation message sent by the original head unit.

I have tested this on my Skoda Superb 2012 with 12 channel DSP Sound System and it works.

Is it same for all kinds of skoda cars and aftermarket radio? 

 

Maybe it is different from other aftermarket radio. 

 

I have replaced the stock radio with an aftermarket radio seicane  S081690 together with the headunit, gps, dvd etc., it is basically a plug and play. 

Hi guys. Do any of you know if the Fabia vRS mk2 came with the DSP/Skoda sound system? I was pretty sure it didn't, but some aftermarket manufacturers have told me it did.

If you don't have the DSP Sound System it is, but if you have the DSP System (in my car the DSP external amplifer is located under the driver seat) you will need a radio unit able to activate the DSP through the Can-Bus or you have to do the steps explained in the first post.

I need to try this method. I sure as hell am not gonna pay 100€ for any after market activator.

 

Would it be enough to just remove the fuses for the radio and amp?

 

Thanks

Here an update from Holland about this. Tried this method in a 2007 Octavia RS with the CANbus activated soundsystem amplifier. Even disconnected battery for an hour... No luck :(

DSP Sound System

 

what does DSP stand for..

I have a 2012 L&K with the "sound system" will mine de a dsp?

I can confirm, that this way was successful for me. 

 

I bought android powered head unit supplied with harness and can bus decoder. After connecting all necessary, sound wouldn't work. After disconnecting baterry the head unit started to play.

BTW its 2010 118kw Škoda Superb combi. With amplifier.

Is it reasonable to assume that this will also work on a 2005 Superb with the DX headunit and an amp in the trunk?

Please help me if you have found a solution for the sound. We have the same octavia model and issue with sound with android installation.

A bit of a thread dredge.  But I'm having the same issue.

 

Octavia 2 Scout with Audience Headunit and the factory amp under the passengers seat.  Installed an aftermarket android HU and everything works except sound.

I have volts AC on speaker outputs.  I have canbus control working for everything else (steering wheel buttons, steering angle etc). 
But I have no sound through the speakers.

 

Disconnecting the battery didn't help.  I've done that overnight.  Reconnecting the stock HU works fine.

 

Does anyone have a work-around, known working canbus adapter or other method that doesn't involve splicing 2 dozen wires?

This post is to give formal credit and a BIG THANK YOU to mspider65 for his simple and spot-on fix for the issue I was suffering with my Android Head Unit.

My car is a Skoda Superb Combi from 2011 equipped with the so-called "Sound System" 12 channel DSP amplifier. After the original (indeed a very expensive option) RNS-510 Columbus went briked for the second time (the first time I assumed a €400 repair) I decided to purchase a very cheap Aliexpress Chinese 10" Android 12 Head Unit. The HU fitted perfectly, and everything worked beautifully smooth, well, everything but the sound itself. I returned the Android unit and ordered a replacement, in which the issue was exactly the same, no sound from the speakers whatsoever.

I took the car and the HU to a professional car audio service. Result: I was billed €69 for their time only to be informed that the original radio was the only that would be able to interact with the DSP amply.

Then, after many many hours of internet research (if you are reading this you know what I mean), I found this post from mspider65. Just a few hours after (I had the battery disconnected for a couple of hours) my head unit was amazingly alive.

Did you ever find a solution @Kiwibacon?

Fellow kiwi here with a 2008 pre-facelift vRS with the same Audience head unit and 12-speaker Sound System. Would very much like to upgrade the head unit but haven’t yet heard of a success story

Sure did.  I wrote it up here: 

Basically removed the original under seat amplifier and replaced it with filters so each speaker would get the signal it needed.  That post has all the wire numbers and functions called out in case it helps someone else.  The wiring is a bit of a faff and I had to make brackets to hold everything down.  But it works perfectly.  It could be done with simpler filters than I used too.

 

Except for my aliexpress head-unit.  Poxy thing has the wrong firmware and won't respond to any of the physical buttons.  The seller was going to send firmware upgrade files but stopped responding.  Turns out that's the level of support you get for $NZ140.
Buying a new one will be less drama than trying to get this one functional.  But it sounds good, has bluetooth and a reversing camera.  So even without the buttons it's been worth it.

Would this make any difference?

I can confirm that this device can activate DSP sound system. But, preliminary it is not compatible with rcd330. The head unit is not behaving as it should be, it acts like it has only battery power, without ignition 12v....

I did the disconnect of the ground cable on the battery, it worked but there's a nosie, even with no sound on. Buzzing. Is there a way to get rid of that? Quite annoying
