Oh man, I really got things going... My setup looks very similar to the picture you posted for the cubby hole.

Even with reducing the EONON to -15db (lowest setting) the sound quality is meh... So from what I'm gathering... The only way to really get this tuned in is to basically rewire the whole car?

I added my cubby and amp pictures for confirmation. For the amp you need to zoom in, but it has the info that I posted on the original post.
