I have never messed with car speakers/subwoofers before so excuse my inexperience. Long story short, I was gifted a P300-10 and figured why not install it in the brz.

My main question is, will the below harness connect at the amp instead of the head unit? If I can connect it at the amp, it would be much easier and I wouldn't have to run wires from the hu to the trunk.
