Guide to Precision Power Two-Channel Amplifiers for Cars
Two-channel amplifiers for cars provide a variety of car audio setups such as boosting a subwoofer and connecting two channels. Precision Power is a brand that offers several models, ranging from two to four ohms and 600-1,000W. This means you can amp up the power of your existing stereo and listen to your favorite songs the way they're meant to be heard.
What is a two-channel amplifier?As its name suggests, this device separates power into two channels. You could bridge them together for delivering more output to one channel. Some people use this method for amplifying subwoofers. Two-channel amplifiers can play audio ranging from 20 to 20,000 Hz, which is the typical frequency range of audio that humans can hear. They are classified as stereo devices because they have a left and right output.
Can it power more than two speakers?Yes, this type of amplifier can power more than two speakers, although most people use it for powering two speakers. If you have more than two, you must adjust the impedance and power distribution to maintain audio. Impedance, measured in ohms, is an indicator of how much electrical signal is allowed through. Low impedance is associated with allowing greater electrical signal flow. Note that it doesn't necessarily increase the flow; it only makes it possible for more to pass through. Typically, if your car speakers are four ohms, you need an amplifier with more power. Your car audio system could be damaged otherwise.
How do you bridge the amplifier?Before bridging the device, ensure that it can handle the extra load. Some products come with instructions on how to bridge them. You can bridge the device by the following steps:
- Locate the terminals, which should have labels like FR+, FR-, FL+, and FL- to help you know which wire goes where. There are four terminals on a two-channel.
- Connect the speaker wire from channel 1's positive terminal to the device's positive terminal.
- Then, connect a separate wire from channel 1's negative terminal to the device's negative terminal.
There are two ways you can approach this task: build a system around the amp or choose the other components first, then find an amp that powers them. Ensure that your car's battery can handle your car audio system. You can use an auxiliary battery if it doesn't. A rule of thumb for checking if a product is compatible with your car's system is multiplying the RMS value by 75% to 100%. That's the minimum it needs to put out in order to handle the load.
Also, clarify what you plan on using the amplifier for. Are you amplifying a subwoofer, two woofers, or two coaxial devices? In the instance you're picking an amp first, consider what type of audio demands your listening needs require. Some options that Precision Power has are:
- Black Ice 880W Max
- PPi TRAX Series
- Black Art
