have 03 tahoe made power con to batt and have alt wine through spk all the time how do i get rid of it 
1st, don't get power at the battery. Get it at the B+ terminal at the OEM electrical center.
Ground the black GND lead to the body near the radio. Make sure it's a good ground. A TEK screw is not a good ground.
If the problem persists, install an EMI filter in the radio's power lead.
