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!

This really solved my problem, I had ordered a Chinese Android Head Unit with Raise Canbus, all the Canbus functions were working except Car audio as the amp was not powering on, tried many options including adding another Canbus just to turn the amp on it still didn't work but this solution helped me after my struggle of 4 days.

 

Thanks Max (mspider65)
