- CAR STEREO SYSTEMHEAD UNITS
Head Units Overview
In a perfect world, your head unit would be used to provide a signal to your amplifiers that is line level and you would not use its internal amplifiers (if any). They usually do not have the power and strength to drive speakers both loudly and cleanly. The line level signal is cl - CAR AUDIO MISCELLANEOUS
What is Alternator Noise?
Alternator noise is a high pitched whine created by the car's electrical system. If the engine spins quicker, noise frequency is higher. That is why you would hear alternator noise coming from mids and tweeters, but not subwoofers, since subwoofers only play low frequencie - CAR AUDIO SYSTEMHEAD UNITS

Enclosures for Car Stereo Woofers:
Because woofers move a lot of air they generate a back wave behind them. Mounting a woofer in a free space without an enclosure will cause a loss of bass as the back wave cancels the sound from the front of the woofer. There are many different types of enclosures fo - Planning Your Car Stereo System
