There is usually a blue wire coming out of the back of the head unit... it's
called the remote turn-on. Some amps also have a input called the ignition
turn-on. The ampllifier has to see +12 volts in order to operate. (I would
check the amp fuse also).
If you go to multiple amps, I would use a relay for the remote turn-on, along
with a single point ground for your system. I had a pretty bad problem with
ground loops when I installed the first system in my car.
Hope this helps...
