I heard that question many times before, "I really need a crossover?" Timeless I immediately reply, "Yes you do." Whether it's a passive crossover or an active crossover, car audio system will never sound good without a crossover. I will be very clear here, so before you get confused talk about what a car audio crossover, and why you need one.

A crossover is a filtering device which limits the frequencies that reach aspeaker. Shares a musical signal in different frequency ranges and sends them to speakers that are designed to best reproduce each frequency range. For example, only the high frequencies to the tweeter, midrange speakers for midrange and bass for the subwoofer is sent.

The passive crossover is very common. It is basically a capacitor or coil installed on the speaker leads between amplifier and speakers that stops certain frequencies in the range of a speaker. E 'relativelyinexpensive and easy to install.

But for your car radio to do better and be effective, you must have an active crossover, also called an electronic crossover. It 'installed between the unit head or a gun and your amplifiers. Your electronic crossover sends its frequency range to each amplifier. Some people run three separate amps: one for bass, one for midrange and one for the treble.

Active crossover is almost infinitely adjustable. Youvary the crossover points and adjust the individual speakers, the best overall sound in the car to reach.

If you are serious about sound you must have a crossover car audio. Otherwise your system will sound terrible. Oh, what a mess it will be when your subwoofer and mid-range speakers, copies of many of the same frequency! As you know when your mid-range speaker attempts to get out of high notes that the tweeter should be treated. You can stand the pain like? Ican not.

And this is just the beginning of your sadness and pain. Since low frequencies are sent to the tweeters there will be distortion. As a result of this distortion your tweeters will be destroyed. Hard Bass will your mid range speakers, like Dr. destroyed. Now you have to start from the beginning and a new set of speakers to buy anything, because you started with the wrong foot.
