Sometimes, you just charge to crank up the volume. Car audio systems must overcome a good deal of ambient noise--a vehicle traveling down the highway in the congregation of other loud engines is surrounded by a high background boom level. Factory-installed head units have a modest lot of amplification (generally about 10 watts per gully or less), and alive with aftermarket head units have at least twice that. The besides power the amp included with your CD or cassette player delivers, the cleaner the stable from the speakers. But be careful--a receiver rated at 50 watts maximum power probably out-of-date no Car Amplifiers greater than 20 watts of clean power. For that reason, serious mobile listeners eschew the modest amplifiers built into head units and instead opt for powerful external amplifiers.
