Why add an equalizer?
Letís talk a little bit more
In laymanís terms, an equalizer

Most stereo systems on the
market today basically have two to three different tone
Low or bass
High or treble
will have all three, but will control a much wider range
Low bass and others
Most humans have a hearing
range of 20hz to 20Khz.
The 20hz range are low frequencies such as
20hz to 5khz bass, 5k to12k midrange and high 12hz to
As mentioned before, most audio systems will only
incorporate two to three different tone controls.
Low (Bass) = 20hz to 5khz
Midrange = 100 to12k
High (treble) = 12hz to 20Khz
Each frequency covers a specific
sound, musical instrument, voice etc.
Notice the limitation of

What the equalizer will
do for your system will essentially spread the 20hz to 20Khz
in five more manageable controls, allowing you to
"customize" your car stereo system to match the vehicles
interior acoustics and your audio reproduction preference.
Some folks like lots of treble and others prefer a lot of
