Isn't that the reason why the recommendation to connect directly to the 
negative battery terminal was made in the first place? To ensure a low 
voltage drop at high currents? I don't think there are very many people 
out there that measure the resistance between the negative battery lead 
and the point on the chassis where they intend to ground the radio.

Yes, when the car is new. After a few years that can be different, 
however. Been there, done that. The nice thing about a bad battery to 
chassis connection is that you'll probably find out about it before you 
attempt to turn on your rig. :) (car may not start due to a constantly 
rebooting ECM; no fuel pressure; chattering relays when you try to turn 
on your lights without the engine running...)
