        Type of the Speaker

        Car speakers usually come in 3 types:

      • Component Speakers

        Component speakers have separate woofers and tweeters with crossovers. They give a stereo-like effect to the sound.

        While buying a speaker the most common mistake people make is ordering the wrong size. Make sure what size and mounting depth of your speaker is.

        Sound Quality

        There can be a number of issues with the quality of sound of a speaker -it could have distortion, flat bass, dull highs, and low volume. Check the speaker for all of them. The best way is to go through customer reviews.

        Durability

        The durability of a speaker depends on the quality of materials used and the sophistication of the system. Check the speaker for both of them.
