Pioneer TSQ131C Advice Please!!

[g4ryw4tson]

Hi,

I have recently installed the following

Clarion CZ509ER H/U
Pioneer TSQ131C components
Pioneer Underseat sub

The problem i have is when the h/u is set to flat ( bass 0, mid 0, trebble 0) the tweeters are quite overpowering. To try and combat this i have to drop the tweeter volume to -6 on a +7/-7 level which makes them sound like mids! Has anyone else had this problem? even on -6 the snare for example is soo sharp at times. I must have spent about 10 hours now trying to get it even close to how i would like it but cant. I have also tried to set this up with fader set to front and i know the factory rears produce a odd sound on their own. Any ideas? Could it just be a missmatch between H/U and Speakers?
