My boyfriend just installed a new deck, amp, sub, and capacitor in my truck. Everything works well when it's on turner, but if I change it over to cd iPod aux or Bluetooth no sound will come out of my door speakers but will have base and sometimes vocals coming out of the sub. Why isn't it working?
The problem is that the amp turn on signal is connected to the antenna turn on rather than the amp turn on. So only when the tuner is on the amp is turned on.
