I have an AlpineCDE-7858 in my car and it has a subwoofer out and it sounds great. MY question is ,I'm changing the head unit to a CDA-7839 which has dual pre-out and a non-fading pre-out button. If I want to use my subs which pre-out should I use the fron or the rears?

I don't know which ones are the non-fading pre-outs that's why I asked. Are the front ones or are the rears the non-fading pre-outs. This will help me determine which ones to use because I am only using one amp.

I just checked your owner's manual. It says that you should use the eject button (press and hold for 3 seconds) to toggle Non Fading Pre-Out on and off.

N.F.P. ON: In this position, the Front Pre-Output will not be affected by the fader. This is ideal for driving a subwoofer amplifier.

N.F.P. OFF: Returns to normal fader mode.

note: Set the N.F.P. to OFF unless the subwoofer is used.

I'm not sure, but what you're calling two outputs is actually two jacks. This is the pre-out. Use standard twisted wire cables to connect to the amp. Select N.F.P. ON with the eject button.

Stevdart,

Thanks Alot that means I'll use the rear pre-outs for the amp and subs. Not the fronts.
