the controls on the HU are pretty good, for the average car audio person. I have had a few systems installed over the years, I liked the Epicenter for OLD Rock(Steeley Dan, Kansas, Beetles) it just gives the bottom end a little bit of a boost. But, when switching to the radio to get a traffic report, it kinda sucks flexing the windshield with TALK or commercials. The EQ's are nice to TWEEK ON, but, I just set up the crossovers on my amps and use my HU controls for the Subwoofer section, HPF, etc.
Maybe I'm just getting lazy in my old age. Of course my opinion and $.50 can't even get me a cup of coffee.
