Subwoofers are dedicated to reproducing low audio frequencies and provide depth to the overall sound of your music. We carry a variety of subwoofers in all shapes and sizes. When choosing a car audio subwoofer, keep in mind the amount of space in your vehicle and your preferred style of music.
The RMS power handling rating refers to the amount of power a sub can handle on a continuous basis. We recommend giving your sub 75% – 90% of its recommended RMS rating to help prevent over-powering or “blowing” your sub. You should select a car stereo subwoofer based on the amount of power output generated by your amplifier, the sub’s impedance and the voice coil specifications. Subwoofer impedance can be rated at a 2 ohm, 4 ohm, or an 8 ohm load. The number of voice coils allow for different wiring configurations. The type of voice coil setups includes single, dual, or quad voice coil.
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the sensitivity number, the greater efficiency. A higher sensitivity rating also indicates that the speaker will play louder, given a set amount of input power. This is because 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.
