You can't go wrong with a powered subwoofer for your vehicle. You can customize your sound system with added bass and you don't have to use an amplifier. But the powered subwoofer on your vehicle can only produce 12 volts, while your car's battery can produce just 24 volts. For that, you'll need to purchase a pricey power amplifier and not an inexpensive portable subwoofer.
Cheap portable amplifiers are actually even better than premium built-in amplifiers. A cheap amp allows you to remove the crossover and send the output to your speakers instead of to the amplifier. The disadvantage is that you must keep careful watch of the amp's volume level to make sure that you aren't overlapping the bass. With the cheap amp, you may notice that the bass is a bit dull. That's because the cheap amp might have insufficient power to pump the bass frequencies.
If you use a powered subwoofer with an amplifier that's too large for your system, you'll get subsonic sound quality (that is, low frequency sounds produced by the low frequencies) when listening to music. This is called "sonic distortion." You may be hearing a fluttering, whining, or whistling noise from your speaker. You may think you're hearing static or a scratchy tone, but it's all in your imagination.
If you own a powered subwoofer with a much larger amp than the one that powers your vehicle, it may not work very well. You may experience the portability problem described above, since the subwoofer is held too close to the amplifier. Or you could find that when you operate the crutchfield as a stereo, the sound from the amp gets blended with the sound from the speakers, making a jittery sound.
There are many car subwoofes that use smaller, simpler amps to operate. However, you must keep in mind that even a small amplifier can still make a loud sound if you place the speaker too close to the engine. For this reason, many people choose a powered subwoofer with an external amplifier. The external amplifier plugs into your vehicle's audio system so that the subwoofer output can be controlled precisely. You can adjust the volume and send the sound to your home stereo or to your personal music device, such as your iPod or MP3.
The best-powered subwoofers usually come with their own amp. That's why it's important to match the power output of your amp to the wattage of your subwoofer. If you don't have an amplifier with the same wattage as your powered subwoofer, you may experience uneven sound or missing bass.
The best-sounding and bass-heavy powered subwoofers come in many different styles. A few popular styles include Bose, Alpine, and Focal. Bose makes a couple of excellent products including the powerful Live Wire subwoofers. They are made out of high quality materials, including solid plywood and aluminum. Alpine makes an inexpensive but good-sounding home theater speaker called the Live Line series.
When it comes to car audio systems, many people think of speakers connected to a set of amplifiers. But, there are many kinds of home theater subwoofers, including theater powered subwoofers and those designed specifically for the car. It depends on what you like to listen to and how much space you have to install a subwoofer installed in your car. Most auto parts stores carry a selection of car audio subwoofers, and you should be able to find a model that works well in your vehicle.
When shopping for a subwoofer, it is important to make sure you choose one that is compatible with your sound system. Many car audio subwoofers use a potent yet passive amp to handle the power of the woofer and prevent it from getting damaged by loud noises. For your information, passive subwoofers utilize a solid-state amplifier to convert the incoming signal and send it out as sound using the speaker cone.
An efficient home theater system would include a powered subwoofer. You can get a powerful yet passive subwoofer by checking out some information on some of the websites dedicated to selling subwoofers or car audio equipment. As for your vehicle, you need to check with the manufacturer to see if the car audio system will work with a powered subwoofer. But, if you don't have a vehicle, you can make use of an inexpensive powered subwoofer that you can install at your home theater room. To make sure it is a good product, read online reviews of various car audio subwoofers and you should be able to get the information you need to make the right decision.
There are many benefits to using a powered subwoofer in your home theater. One of these is that you will hear clear dialog regardless of where you position the speaker or whether you adjust the volume. This means no more complaints from guests asking why you can't hear them because the speakers aren't positioned where they wanted them to be. Another benefit is the frequency response. External amplifiers with built-in preamp output terminals can take away the effect of the built-in amplifier and improve the frequency response.
