It's really not that bad but I am very critical when it comes to sound. Question to all that have installed the KTP-445u. Do you notice a slight hiss at low volumes? Just curious to see if I'm wasting my time trying to completely remove it. It is unnoticeable after you turn it up.

I couldn't afford those but bought the Infinity REF-8602cfx speakers. Since Crutchfield had them on sale for $103.99/PR with free wire connections normally $129.99/PR with no freebies.
