In general true, but there are practical limits in both size
and inductance - the big caps start to look a little like an RLC
circuit.

If you have a bleed resistor across the terminals, make sure that the supply
line is switched - if the supply does not switch off, it's the battery you'll
be bleeding...

Yeah, like this, for instance. In this case you would have to make sure that
the bleed resistor (and cap) comes after the power switch for the stereo.
