1. Started with driver side speaker not working2. Next day, entire speaker system would not turn on - static noise when I increase the volume - also knocking sound "Du Du Du" three at a time every 3-4 sec or so.

- knocking sounds mainly coming from left side ( if I adjust the equilizer to shift to passe ger side it goes away)



Trouble shooted so far.

1. Soft restart pressing volume **** +/- tune ****.

2. Took out and reinserted fuses:

- amp/anc - uconnect center - entertainment media hub - right door mod

any other trouble shooting suggestions??
