My 2015 Toyota Prius V Complete Sound Deadening + Audio System Build

This thread documents my 2015 Prius V refinement project focused on cabin noise reduction and an audio system upgrade. The goal is to improve daily driving comfort and in-car sound quality through a complete NVH and audio system build.

 

I eventually decided to upgrade the audio system in my Prius. I already had a few components, and after researching different setups online I picked up the rest of what I needed.

Before touching the car itself, I wanted to make sure everything was working correctly, so I set the entire system up on a test bench at home first.

 

I needed some lugs, battery terminals, circut splitter, wires, fuses

 

Important note: wire terminations. I'll came back to this later
