An equalizer in your car can give you total control of the audio system and allows you to adjust tones more than your standard treble, midrange and bass controls. Equalizers in cars come in various types. In or under-dash, or ones that can be installed in the trunk or cargo area of your car. Be careful when purchasing an equalizer. Some are designed just to work with one brand so you may have to change your entire audio system. You can also find equalizers that come with a subwoofer output set of preamp outputs. Some feature line drivers that boost the voltage from your receiver to the maximum level accepted by your amp. An equalizer basically gives you ultra-precise tone control so if you're a music junkie, give it a thought.
