Hello,

 

I had an Avic N2 installed into my car, however when the guy installed it the first time there was this buzzing noise, so what he did was he cut the wires off to my amplifier of my car. He said the Avic N2 had an amplifier already. How does this change the sound quality? is this safe and okay for my car?

 

I drive a Porsche Boxster.

 

Thanks for all your input.
