When you are buying an amplifier you first need to figure out why do you need it and how are you going to use it. You need to know if you are going to power a sub or two subs, or one or two pair of speakers or oven both subs and speakers. When you got this figured out then you can get what you need based on how much output channels and also how much power you need. Mono amps have one output channel. Next thing you have is two channel amps. Next thing you have is 2 channel amps. These are much better because it gives you more choice and versatility. You can use two output channels to power a pair of speakers. They can also can be bridged and turned into a single channel. 4 channel amps gives you the most options. They are perfect for powering a couple pair of speakers. Next thing is 5 channel amps. 5 channel amps lets you power your entire system with just one amplifier.
Next thing you need to know is how much power you need. There are two things you need to know about. Peak power and RMS power. Peak power is what an amp can produce in a very limited burst of power. This power is not actually very useful and it is better to look for RMS ratings when you are checking for quality. RMS is the measure of the amps continues power output. So when you are shopping you need to be more concerned and look for the RMS ratings.
When it comes to power it is always better to have more power. The more power you have the better. You want that your amps can play all of your music whether it is loud, extra loud or soft without distortion and also that it can handle sudden changes in volume. Match or exceed the power of your speakers with power of your amplifier. Remember, more power is always better.
There are also filters that enables you to amplify certain frequencies to maximum. High pass filters strip away the low frequencies and that way vocals and instruments will be in the first plan. Low pass filters to the exact opposite. They take out the high frequencies and they only amplify the low frequencies. Also there are variable filters that allows you to select the frequency for the filter. On the other hand other filters are fixed and the can limit you to a specific frequency. Variable filters are certainly more precise.
When you are buying an amplifier make sure that you get the right one. Long story short, get the expensive one. You will get much better sound overall better sound quality. There is reduced risk that it will heat too much and that the bad placed wires will make distortion. What is also important is amp wiring. Your amp needs and depends on steady supply of power. That’s why you should buy a high quality amp wiring kit. If you use thin or too cheap wires, you are reducing the abilities of your amplifier by denying power to it and more power is always better.
