I have a DEH-4000UB head unit. This thing has been awesome for the last month. Tonight i took my amps out and cleaned up all the wireing. Now when i put everything back i go to play music and the subs are on even when the sub output is off on head unit. When i turn the output on subs get a little louder. When i unplug sub preamps my 4 door speakers sound really weird to where voices are low and piano and **** are really loud? I dont know WTF is going on and getting pissed about it. any idea's whould be great. By chance head unit went bad? i dont see how but i am confused for the first time on this..... it's probly something stupid.
