Bridging an Amplifier Bridging an amplifier involves taking the power of two channels and turning it into a single channel. Sometimes you can more than double the available power. Bridging is a popular way to drive subwoofers. What you are really doing is combining the power of two separate amplifiers enclosed in one case. Often it is less expensive to use a two channel amplifier than it is to by a mono amp producing the same power. Just be very certain you know what you are buying and understand what is happening. Check for certain that your amp is bridgeable. Your sales representative or installer will know, or the owner’s manual will have directions. Amps from different manufactures are different, but usually it involves connecting the speaker leads to the positive terminal of one channel and the negative terminal of the other channel. Be sure you have enough load to keep the amp from overheating. Our professional team has a lot of experience in installing and bridging an amplifier and knowing based on the equipment and design of your system when it is advisable and when it is not.

What is a Car Audio Crossover?

What is a Car Audio Crossover? What is a car audio Crossover? As soon as you start to move past the factory sound stage with your car audio system you will need to know what a crossover is. As you upgrade your system you will start encountering crossover filters. They will be designated as high-pass or low-pass. These are the tools for getting the best sound from your system. Car Audio Crossovers may be located in your car audio receiver, in an amplifier, or they may be separate parts in many component speakers systems. In all cases, the purpose is to send the sound to the speakers that can handle it best. A low-pass filter stops the higher pitched sounds from getting to your subwoofers. It makes sure that your subwoofers only get the frequencies they handle most efficiently. A high pass filter does the opposite, sending only the higher pitched music to the mid-range speakers and car tweeters. Adjustable crossovers let you fine tune the sound for your specific system. For instance, the low-pass filter setting will be different if you have 15 inch subwoofers than it will be if you are using 5×7 speakers for your bass. The manual that came with your components will suggest settings. Understanding what is a car audio crossover and how it works is critical for getting the best sound out of your car audio system.

What is a 4 channel amp

What is a 4 Channel Amp What is a 4 channel amp? Simply put, a 4 channel amp puts out equal power in four separate channels. At its most basic, a 4 channel amp can be used to power two pairs of full-range speakers. A 4 channel amp starts to show their versatility when they are bridged. This involves combining the power from two of the channels into a single channel. Many 4-channel amps are bridgeable to three or even two channels. In a 3-channel configuration, you have power for a subwoofer from the bridged channels and two channels remaining to power a pair of speakers. Bridged down to two channels, the amp will provide power to two subwoofers, or a single dual-voice-coil subwoofer. Why do you want one? The difference even a small amplifier makes compared to what is often referred to as “deck power” from a factory radio can be amazing, especially when you upgrade from your OEM speakers. An un-bridged 4 channel amplifier gives you a great deal of control over the balance and fade of your speakers. It also provides more punch for the mid-bass sound. Bridging often produces more power than the simple sum of the two channels for a woofer. Here’s a word about bridging: it can be tricky. Not all amplifiers are built to be bridged, and not all bridgeable amps go about it exactly the same way. When you bridge an amp you change the impedance. There is a danger of damaging the amp, speakers or both. Check the owner’s manual before you start, and if it still looks puzzling, get expert help. Our staff at Audio Express / Quality Auto Sound will be glad to show you which amp you need, and our professional installers are experts and amplifier installation and will install it at the guaranteed lowest installed price in town.
