Can someone please help me - I am pulling my hair out. I have just installed a new JVC head unit (top of the line) into my 05 corrolla and am now having problems with the speaker sound cquaility. I have Boston Acousic Rally Spliyts in the front and Boston Acoustic Coax in the rear doors with a Sony 10in Sub in the boot. Problem is there doe not appear to be any staging at the front and the fornt splits sound flat. I have them running off the head unit ut have also trued them off an amp and there is no difference. Is there something I am missing, is it the cars acoustics that do not suit the speakeres???????? HELP
