Car Amplifier Basics

Let's start with the recognition of the different types of amplifiers. You have your basic mono-channel amplifier, your amplifier has two channels, and then you have multi-channel amplifier. A "channel" is simply a set of positive and negative (+/-) terminals on the amplifier from which you use to power or the drive to come to your speakers or subwoofer. A mono-channel amplifier has a number of terminals, two, two channel amplifier, and multi-channel amplifier range from anywhere between 3-5 channels. Now we go into details to discuss their best intended applications. We also answer the questions most frequently asked questions.

Mono-Channel Amplifier Mono-channel amplifier tend Class D "amplifiers. Class "D" amplifiers have a high current ratio, that is exactly what you are looking at power subwoofers that a lot of electricity. Class "D" amplifiers are also known to be very effective. Since Mono-channel amplifier best work at 2 ohms impedance, they are best suited to either sing a 4 Ohm Dual Voice Coil Drive "subwoofer, 4 Ohm or two subwoofers that only" a voice coil "of each.

Why are mono-channel on the amplifier best suited for this setup? Because each speaker presents a load impedance of the power which it is supplied from the amplifier. This burden is in a unit as "Uncle" measured known. Most speakers Subwoofer 4 Ohm resistance. If properly connected, you will lower the load impedance that the amplifier sees. It is the impedance of 2 ohms, where most of the mono-channel amplifier to build to the best performance is lower.

Two-channel amplifier is a two-channel amplifier, an amplifier, a right and a left channel can be operated. It is basically two mono-channel amplifier in a single box. Since two-channel amplifiers are generally stable when presented with 4 ohm impedance, they are most appropriate, either to drive a 4 ohm single voice coil subwoofer, 4 Ohm or two "dual voice coil subwoofer . To complete this setup, you need to bridge "the channels of the amplifier. Not all two-channel amplifiers are bridged, so be sure that your two-channel amplifier is bridged before you buy it.

What is "bridging"? Let's say that you buy us on a two-channel amplifier, rated at 500 watts RMS. You need to know that the amp does not deliver 500 watts per channel. Instead, each channel is only to deliver 200-250 watts. To get the advertised 500 watts, you need to connect the two channels into one channel. This is called "bridging" of the channels.

* Note-Be careful when "bridging" the connections, because if not done correctly, then you will destroy your amplifier.

Multiple-channel amplifier multichannel amplifiers allow you to hook up several speakers (usually the front two and rear two), while still allows you to control your balance and fading options. When shopping for multi-channel amplifier, you will notice that even though most are still valued in the 2-4 ohm impedance range, some are rated at 20-40 ohm impedance. The only time you ever need an amplifier with this high evaluation of the impedance, if you have multiple speakers in a "series" were wire. Multi-channel amplifier subwoofer can be used, but you must ensure that the amplifier channels are bridged, as most of the time, each channel of a multichannel amplifier is not nearly enough for Watts.

What's "series" wiring? Instead of wiring each speaker individually for each channel of an amplifier, sometimes it is recommended that you have two or more speaker wire together. After the speakers are wired together, you want the entire unit of the speakers on one channel of the amplifier wire. together for the wiring of the speakers, a simple loudspeaker cable from the positive output from a loudspeaker to the negative terminal of the other speakers. Once this is done, run the speaker cables from the channels on the amplifier to your remaining positive and negative terminals speakers.

* Note:-you need to keep track of load impedance, if you are wiring speakers in "series". When wiring in a row, you simply add the number of ohms of each speaker. Make sure amp is rated to run a high impedance.
