Hello all, Thanks in advance for any responses. I'm in the process of trying to figure out how to upgrade the sound on my 2018 Ford Fusion. It has the 11-speaker system that comes with the Tech package. The speakers are quite substandard. My difficulty comes in figuring out what are the limitations in adding an amplifier. Specifically, I need two questions addressed: 1) Will adding an amplifier lead to sound distortion due to microphone placement and/or noise cancellation technology? 2) What are the limitations in choosing an amplifier with regards to power, current, fuses, etc.? I've heard of people installing amplifiers in hybrid vehicles, only to have their hybrid batteries blown out. So this is a very serious issue, and frankly I'm a bit dissapointed that Ford does not make this information readily available. Thanks.
