Piooneer Stereos, reverse subs option?

When i was installing a stereo on my friends car, i was fooling around with the options i saw somehting called reverse subs what the heck is that. (I dont plan on touching that and we havent put the amps and subs in his car anyways) Just want to know what the hell this option does :P the duce

this feature allows you to invert the signal a 180 degrees out of phase with the full range speakers.  It seems to be a case of trying it each way and seeing which outcome gives you more bass.  Really has to do with position the subs in the vehicle and trying to eliminate the sound wave cancelling that usually occurs when your subs face to the front of the vehicle and generally the front speakers back...a true canadian eh!

Theres no way to screw up your subs by doing this?the duce

No, in some cases a sub is mounted in reverse due to mounting depth locations, availability of proper airspace or the person wants to see the back side of the subwoofer.Top Secret, I can tell you but then my wife will kill me.
