Video Lockout Bypass

Installer liable for accident?
A car audio shop installs an in-dash mobile video player and bypasses a built-in safety lockout feature. As a result the car owner is able to watch movies while driving. He causes an accident which results in the death of a passenger in another vehicle. It is determined that the distraction of the video screen contributed to the accident.
Should the car audio shop have any liability? Should the installer or shop owner face criminal charges?
It's the 'lawsuit of McDonald's for coffee being too hot' syndrome. If you're dumb enough to defeat a safety device...well that's natural selection!

On a side note. You often state that "many people believe that distortion is bad for subs..."
It's not distortion that hurts subs, it's the TYPE of distortion as there are many types of distortion and only a few that cause damage.
Clipping is one form of distortion that occurs when an amplifier is overdriven, which happens when it attempts to increase voltage or current beyond its limits.
Distortion refers to any kind of deformation of a waveform, compared to the input.
I thought it pretty well summed up by:
I can drive speakers with a 100% clipped square wave signal all day long with no problems as long as the thermal and mechanical limits of the speaker are not exceeded.
I can feed a speaker 100% distortion all day long with no damage as long as the thermal and mechanical limits of the speaker are not exceeded.
I can exceed the thermal and/or mechanical limits of a speaker and watch it fail in short order.
These are electrical and physical truths and anything else is a myth.
Happy polylogies!!!
