Frequently Asked Questions:
-
What do you mean by a 4 channel amp?
A 4 channel amp means a combination of 2 channel amplifier that come in one package. It allows users to run it in a 4 Ohm stereo load on High Pass. Now, you don’t need to pair it with four speakers. You can pair a four-channel amplifier with two speakers and with a subwoofer. It means that you can pair two speakers and two channels to connect those with the subwoofer.
-
What is the difference between 2 and 4 channel amp?
Many people think that it is the quality that differs both of these two. They think that a 4 channel amp is better according to quality compared with a 2-channel amplifier. But it isn’t true. The number of the channel that connects with the number of speakers plays a vital role here. It is the factor that makes these both channel amps different from each other. However, a 4 channel amplifier can connect with more speakers than a two channel amplifier.
-
How many speakers can a 4 channel amp power?
Usually, the external amplifiers power more than a speaker in each channel. If you take a 4 channel amp, then it can power up to 8 speakers. But it depends on the process of setting it up. It is the first thing that you need to make sure.
-
Can you use a 4 channel amp for 1 sub?
Most people prefer to use the four-channel amp. You can connect it with four speakers or two speakers and a sub.
-
Is 4 or 8 ohms better?
If you want to use any of them, we will recommend 8 Ohm for you. Usually, a 4-ohm speaker needs more power to offer the same sound quality than an 8-ohm speaker. It depends on the voltage, current, and resistance. These three factors play the leading role in this case. If an amplifier has low impedance, then it means that it consumes a vast amount of current.
