There are two main factors that should be taken into consideration when choosing speakers for you car's audio system. The speaker's sensitivity determines how much sound the speaker is capable of producing. A low-powered car stereo will work best with speakers that have a high sensitivity rating. In contrast, a high-powered car stereo will sound better with speakers of a lower sensitivity rating. The power handling of a speaker is measured in watts. It allows you to determine how much power your speaker can actually handle. This is relatively unimportant if you have a low-powered stereo system. However, if you have purchased powerful external amplifiers for your system, you will need speakers whose power handling is at the same level of output as your external amps. In addition to determining how much sensitivity and power handling you require, you also need to choose what type of speakers you want to buy. Full-range speakers contain all the speaker elements you need in one component. They usually consist of a woofer for the lower frequencies, and a tweeter mounted onto the woofer to produce the higher notes. A few models come with additional drivers, such as a mid-range or supertweeter. Full-range speakers are a viable choice if you want to replace factory speakers quickly and easily. They come in a variety of sizes that are easily mounted into factory speaker locations. Full-range speakers are available from major industry names like Alpine, Kenwood, and Infinity speakers. Component speakers include separate woofers, tweeters, and external crossovers. These separate audio speakers work together to produce the best possible sound. Since the tweeter is always separate from the woofer, your music will sound more realistic. Component speakers are made of better quality material than full-range speakers, so they are more expensive. However, all speakers will sound better than the factory speaker in your car. |
