Ok well this is my question I just recently installed a sound system in my truck heres some of the things I have done I put 2 amps rated 1200 watts each 2 mephis 10's rated 800 each and a new kenwood deck! But now this is where the problem starts after installing this my radio and turn signals wouldnt work! I pulled the radio and checked all fuses and all were good so I ended up finding out the 12 volt wire that runs to the battery was bad so I had to run one from the stereo to the battery now one of the amps keep shutting off and cuts out the stereo also on top of this I can no longer lock my doors by the lock I have to press each one down by hand! On top of that when the amp goes out I can't roll down or up my window! Someone help me please any suggestions I need this truck to work!
