I have the PA450UM, and my tower speakers have a constant hissing sound, like interference. It's very obvious when there's no music playing. Anyone have a similar issue - any solutions? Thanks in advance!

Excessive gain

Is it only in the tower speakers, or can you hear noise in cabin speakers as well with volume down with engine running? LOTS of people are having stereo noise due to wiring issues from the factory. (factory has not acknowledged this, but it is definitely a problem) I have a 2015 SAN 230 like you that I am working on now to fix this issue. I will follow up with pictures as soon as I do a final test of new wiring this weekend or next.

It's only the tower speakers. I'm going to modify the gain on my amp as well as equalizer and see if that will resolve. If not then I will look at the ground wiring. Will let you know what happens.

What EQ do you have? Thats certainly can add to a gain issue in regards to tuning.
