In the realm of car audio, if the amplifier is your system's heart, the car sub is its pulse. The subwoofer provides deep bass beats when playing your music and is considered an essential part of a speaker package by many fans of rock and hip hop. Most car subs do not come standard, but you can install one easily--especially if you are adding a new amp as well. A car sub enhances the bass from any audio you play through your car stereo system. How powerful a sound it produces is determined by two factors: how many watts the subwoofer produces and how strong your amplifier is. The more watts your car sub puts out, the richer and louder the sound you will get. Pairing your car sub with a proper amplifier is the key to getting the perfect sound. Buying your subwoofer and your amplifier together helps ensure that you're making a good match. Make sure that the wattage put out by your subwoofer is less than or equal to the capacity of your amplifier to avoid damaging your speakers and amp. If you wish, you can install your car sub into a shielded box to get even better sound. These boxes provide great reverb to your bass sound and magnetically protect your sensitive car sub. You can install your car sub yourself using high gauge cables, or you can bring your purchased subwoofer and cables to a shop for professional installation. Most subwoofers will be compatible with any existing brand name stereo system, but check the specs before purchasing to be sure. |
