Someone posted a question about a head unit in the modifications forum and I thought it would be great to pose it here as I have wondered what the difference is.

The question concerned a particular HU, but could really apply to any unit:

Does anyone know if the Front and Rear pre-outs get the same signal (assuming the fade & balance is neutral)?

Please weigh in on what part of the recording is sent to Front and Rear, if they are the same, if they should be the same, etc. Thank you to all contributors!
