It adjusts the electrical phase of the signal so you can set up multiple amplifiers with speakers in various locations and you can keep their outputs in acoustic phase with each other.

Based on your question I'm guessing that probably made no sense to you. The way to use it is to put your main speaker amp at "0" and your sub amp at "0". Play some music and sit in the driver's seat. Have someone else slowly adjust the phase control on the sub amp. When it sounds best to you, leave it there. If it makes no difference, leave it at "0."

I thought it was used to make the amp invisible, so it won't be stolen, like a cloaking device. :)
