Audio Gurus please help!
My installer put an Alpine IVA-200 in my '07 Vette today in place of the base head unit. It has the Sirius tuner, Bluetooth and Ipod interface. I believe he used the factory amp to power the speakers, rather than the amp in the Alpine unit, but I could be wrong. He also installed a Peripheral unit to retain the factory chimes, etc.
It sounds incredible. Much more power and base, and he hasn't even had a chance to install the sub yet. Now here's the problem: the system makes a loud pop every time we change an FM channel, or change the source from one to the other, or when the bluetooth turns on or off. He' s not sure what's causing this. Any idea's out there??
Thanks in advance!

I had a similar issue with some home theater equipment a few years back. The amp was always on by design. It turned out that the Preamp controller was disconnecting/re-connecting the pre-amp outputs with each mode change, causing the pop. A simple ground-loop isolator took care of the problem.
In your case, if I'm not mistaken, the factory amps are also always on. Try an isolator before you have it all ripped out.
