Im thinking this might be a pretty neat idea. Everyone with an o-scope checks their headunit to find out when it starts clipping. It'd be neat to get a list together with the headunit and where it starts clipping at so others know who dont have an o-scope.
lets try to make this uniform by using the same tones. 1khz and 40hz
Ill start with this...
Eclipse CD7200 mkII (80 is max volume) - Front outs dont clip, sub outs start to clip at 75-76.
I have access to a few other headunits and will post up my findings as soon as i get time to mess with them
