30W AF amplifier for cars
The power that can be obtained from a standard car radio
amplifier operating from a 12 V car battery is 5-6 W, which (for
many listeners) is not really enough for satisfactory
hi-fi reproduction. It is, of course, possible to boost the 12 V
supply with a power inverter, but that is fairly expensive and
not always acceptable. Now, a Philips le enables audio power
of about 30 W to be obtained from a 12 V car battery.
