Hi!
Would appreciate some help.

Was thinking of using a car radio at home. Specs read current
consumption 1.5A (at .5W).
The fuse is 5A.

DC power supply should be at least 1.5A but can I go up to 4A without
harming the radio?
Not sure if I would gain any improvement in sound.



You can't hurt something by having more current available, the radio will
only draw what it needs. Car batteries are capable of hundreds of amps for
short periods.
