I was driving to work and the Z1 began to stop making the normal music sound and started making a scratchy annoying sound, and buzzing through the speakers.

 

The amp was in protection mode, so i tested all the speakers with a speaker pop test. all the speakers were good.

Then i figured i would by pass the amp just in case the amp went bad. Bypassed it and this time i got no sound. at least with the amp it was just a scratchy sound.

 

So i tested the speaker wires again just to be sure and they were all good. I tested the Z1 by putting an old door speaker to it and no sound came out of the speaker, just feed back. So I just bypassed everything and just put the factory system back in and everything worked correctly.

 

Now what my question is could it be the internal amp on the Z1 that has faulted? but if it was the internal amp then the amp should have worked because it by-passed it from the get go.

I have had this unit for 3yrs

 

thanks.
