I recently installed the Alpine iDA-X100 model and I am having difficulties with my sub and amp. It works perfectly fine when it's on radio mode, however as soon as I switch it to Ipod it turns my amp off. Wondering if it could be an internal unit problem or a mistake in my hook up?

Hi,

Initially, determine if the remote trigger of the amp is present on both instances; radio and iPod. This would be the blue or blue/white wire from head unit and would read +12VDC when the head unit is turned on. Otherwise, if +12 is present during radio mode but absent during iPod, then it might be that the internal switching would need looking into or a short temporary fix would be to wire a separate power on toggle switch for the amp.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.
