I have a Clarion DRZ9255 Headunit, JL Audio zr525cSi's, a JL 300/4 pushing those.

Using the headunit as an active crossover; has 8 channel preouts, each with high and low pass x-overs. Built in 5 band equalizer which you can chose your eq points.

My question is that nearly everytime someone in a song says an S it is kind of harsh. I have adjusted the gain on the amp, the x-over points, the polarity, the gain of each driver, the q of each driver, the eq of the head unit. pretty much every function on the amp and decks. Was wondering if anyone has seen or heard of a fix for this.

What you need to do is turn down the eq in the HU around 1000 -2000 Hz. That is the first thing to do and then you need to take and put the tweeter at -1.5 and you should have the problem resolved.
