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.

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.

Hi, i had the same problem with my Skoda Superb 2012 with 10 channel DSP Sound System but i found a very easy way to solve the problem. 1) disconnect the old Head Unit (in my case was an OEM Bolero unit) 2) disconnect the battery for at least 20 minutes (just the minus pole is enough) 3) connect the new aftermarket Head Unit 4) connect the battery After this the amplifier goes in a special mode were is activated by the key-on can-bus message and deactivated 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! Max
