kenwood KDCMP208
 

I just replaced my old Clarion HU with this and it sounds very muddy..I have tried all the settings and finally put everything back to 0...my question is is there a seeting or button that I might have set to cause it to sound Muddy ? right now bass,treble,mid are all set at zero...bass boost is off..the voices sound the most muffled...thanks for any help
