People love listening to music in their cars, whether it’s blues, country or hiphop. Subwoofers give music depth and richness, but just how exactly do you control the levels? This is where an amplifier comes in. They are used to increase the power of a signal from your stereo system. An amplifier also gives you the option of getting clear and defined channels in your car. The type of speaker is an important factor when considering what type of amplifier you need. Here we’ll look at the best type of amplifiers for your subwoofers. An amplifier is a key component to a great sound system, making their influx in the market, high which might intimidate any buyer.
Some people might see choosing an amplifier as an easy task of just going and picking any from a shelve, but there are some considerations to be made. There are several types of amplifiers that are designed for specific subwoofers, so you need to look at some specifics before purchasing one.
Things to consider when getting an amplifier
Number of channels
An amplifier can process a number of audio signals through several channels. One of the best amplifiers is the one that has a single channel. Even when you wire serval subwoofers to this amplifier with the single channel they will all receive the same mono frequency.
Most users usually go for the highest power capacity in amplifiers while sacrificing the sound quality. However this should not be the case as you can get both great power and sound in one amplifier. Unlike other power measurements, the one in amplifiers is measured in Watts and Ohm with the frequency being measured in Hz. Manufacturers may offer some potentially misleading reports when it comes to amplifier power. Average power is generally more reliable than the exaggerated quotations on the products.
You need to match the RMS watts of the subwoofer with the RMS watts of the power amplifier. The RMS wattage represents the minimum and maximum power range an amplifier can stand. If the power amp has a wattage range, you want to ensure the minimum power is 75 percent of your subwoofer’s RMS watts and the maximum is 150 percent of the RMS watts
This is the measure of electric resistance. In order to avoid overheating of your subwoofer and amplifier you need to match their impedance correctly. Matching impedance can be an easy task if you’re attaching one or two subwoofers. However it becomes trickier when attaching multiple subwoofers and devices with two input and two output connections.
Total harmonic distortion
This is a measure on how much effect the amplifier has on the sound output. This is one of the most important factors to consider when it comes to sound. Distortion levels from the amplifier under one percent are fine and hardly distinguishable. An amplifier with a 10 percent THD would yield very poor quality sound at both high and low volume levels. Theres also signal-to-noise ratio which expresses the correlation between sound signal and background noise levels. Background noise is unwanted noise produced by the amplifier itself. This information can be found on the packaging of the amplifier or its manual.
Size and use of the amplifier
Amplifiers come in a variety of sizes and weights. You can find one that fits the space you want to put it. The size doesn’t dictate how well it functions, so don’t weigh your car down with an amplifier that’s too big. Good quality can come in small sizes in amplifiers.
How you plan to use the amplifier also counts. How many devices do you want to connect to it? What kind of sound will you play? Do you need more than one channel? All these questions determine the type and make of amplifier you need.
Class of amplifier
This has to do with harmonic distortion as it is connected to the output stage when distortion occurs. It has two sub stages: amplification of negative voltage signal and amplification of positive voltage signals. Ranging from class A where both sub stages are on at the same time making it highly efficient. Class B where when one sub stage is on the other is off with an efficiency of 50-75 percent. Class AB is a hybrid of sorts in which both sub stages are on at the same time but they alternate between high and low signals. Class D it’s input signal undergoes a conversion into a sequence of output pulses of higher voltage with a power efficiency of 90 percent.
