I was wondering if i could get a little electrical system primer from someone.


I just bought a Sony 0 disk changer and im about to install it (will take pics)
but when reading the directions the power supply needs to be hooked up to
1. "the 12 v DC power source that is always on
2. "the 12 v DC poser source that is turned on when the ignition is turned on

I had assumed that it would be like an AMP hookup but now i have no ideaa

So if anyone know please feel free to let me know.

What's the confusion? Seems pretty clear to me...

#1 gets connected to a power source that is always live (like the battery)
#2 gets connected to something that is only on when the ignition is on (like power windows)

So basically, it is sorta like an amp since amps also have two power hookups...

1 gets connected directly to an always live source - preferably the battery and the other gets conencted to a remote turn on lead from the radio head unit. The remote turn-on lead has the job of telling the amp when to turn on and off - it acts like a switch.

The #2 connection to your changer acts the same way as a remote turn on for an amp. If you didn't have this connection your changer will be a constant draw on your battery - it's the same way with an amp.

Hope this helps.

Thanks for the info.
