Aftermarket car speakers are built with materials that are durable and temperature resistant. For example, most auto speakers include a rubber or foam surround for enhanced durability. Our wide selection at JL Sound includes various sizes of full-range 2-way, 3-way, and component speakers.
The most important figure to look at when gauging a speaker's quality is its sensitivity rating. An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play given a set amount of input power.
An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter away from the speaker. Some are measured with 2.83 volts of input rather than 1 watt.
