Car subwoofers are large speakers that are used to create frequencies that ordinary loudspeakers are unable to produce effectively. These frequencies are usually in the range at or below 100Hz. These subwoofers are typically 8 inches or larger, and have to be placed in an enclosure to function properly.

Types

1. There are several types of car subwoofers: tube-type subwoofers and vehicle-specific subwoofers. The tube-type car subwoofer contains the subwoofer on one end and is sealed on the other. Vehicle-specific subwoofers are built primarily from wood and fiberglass. They are designed to fit into “factory-created” pocket. These tend to be more specific than the tube-type due to the fact that they are specific to one vehicle.

Considerations

2. Car subwoofers tend to take up quite a bit of space because of their size. Anyone considering the purchase of a subwoofer must take the space factor into consideration before buying one. The smaller the space within which to place a subwoofer, the more the power of the subwoofer will have to be increased.

Features

1. Features of car subwoofers include enclosure type, power handling and sensitivity. The enclosure is basically the kind of box the actual subwoofer will be mounted in. The power handling is the amount of power the speaker can withstand before failure becomes imminent. Sensitivity is a measure of a specific amount of the subwoofer’s power at a certain distance. The standard car subwoofer sensitivity is 1 watt of power to 1 meter of distance.

Misconceptions

2. Generally speaking, one 12-inch car subwoofer will be more powerful than two 10-inch subwoofers. There are a number of factors that need to be taken into consideration when making this choice, but for the most part, one larger subwoofer will have more clarity and more punch than two smaller ones.

Function

3. Car subwoofer cones are made of treated paper or composites. Paper is too lightweight to withstand the power of the subwoofer for extended periods of time, but it also tends to be more responsive. To achieve a “big bass” sound, increase the number of car subwoofers. The greater the cone surface area, the greater the sound. buy subwoofer with fast cash

IN DASH RECEIVER

In any car audio review, the most common question that people considering a change of car stereo system ask : will anaftermarket radio fit into my vehicle ? And the answer is … (roll the drums) … YES, becausethere are a variety of aftermarket kits available to adapt just about any aftermarket radio toyour vehicle.

AMPLIFIERS

The location of the amplifiers in the vehicle is not critical, as long as they have enoughair flow and are mounted on a dry surface. If you install the amps yourself you will needa kit consisting of power wire, ground wire, RCA, remote turn on lead and a fuse. Crimpersand a drill are all the tools required.

CAR SPEAKERS

There are two types of CAR speakers available : the dual cone and the two way. A dual cone has a small paper cone built into a larger paper cone. A two way actually mounts a separate tweeter on the larger paper cone. This allows for more frequency response and better sound quality. You will need to check the fit of your new speakers with your vehicle. You can take off your speaker cover and measure it. Make sure you get the depth if you can. Not all cars can accommodate speakers with a larger magnet.

HEAD UNIT

You should also consider other important but often overlooked features in going through your car audio review. Many models offer detachable faceplates. This security feature will only work if you actually remove the faceplate. Some models have a plate that rotates when you turn off the vehicle, which makes it look like it’s been removed.

Another feature is an automatic volume control : the system automatically adjusts the radio volume up or down, depending on the vehicle’s speed and the varying amount of road and wind noise in the vehicle.

Look for a unit that has large buttons versus small. Large buttons are easier to find and use. The radio should cause a minimum amount of distraction so the driver can keep his eyes and attention on the road. If you want to push this idea to the limit try to find a radio with greater spacing between the buttons. This makes the radio easier and safer to use as well.

The last head unit feature to discuss in our car audio review is the radio display. Large numbers and a clear readout is another reason for an enjoyable listening experience. Also, look for a radio that shows not only the radio station call number but also the time and preset number.
