Hello, I just upgraded my F90bt to Z110bt and just installed tit yesterday. Now the problem is my rear speaker sounds really low compare to the front. Front speakers and tweeters sound awesome. My sub is working fine too. Just no 2 rear speakers. Did i screw up some wiringM Another problem is sometimes the audio just got cut off while I am changing staging sounds. it will come back up after a few mins later but its annoying. Is that the way it is or something wrong with my unit? Thx for all ur help.

any input?
