HOW GOOD IS THE SOUND QUALITY OF CLASS D AMPLIFIERS?Ĭlass D amplifiers may produce slightly more noise than traditional A/B amplifiers, which could be heard as a hiss, particularly when the gain is turned up high. They work by switching transistors very quickly to create an audio waveform, which saves energy and produces less heat. On the other hand, class D amps are much more efficient and can be made to fit in smaller spaces. The traditional class A/B amp has been around for a long time and uses a design where transistors remain on even when there is no audio, making it less efficient. In simple terms, there are two types of car amplifiers: class A/B and class D. Power handling capacity that matches your needs.ĭIFFERENCES BETWEEN CLASS A/B AND CLASS D AMPLIFIERS.High-pass feature to prevent distortion and improve sound quality.Good quality terminals for easy and secure wire connections.Built-in high and low-pass crossovers (adjustable is preferable).It’s important to check for these basic features before making a purchase: THINGS TO CONSIDER WHEN CHOOSING A CAR AMPLIFIER Bi-amping sends signals from one channel through both sets of drivers at matching volume for improved performance. In contrast, an amplifier that powers two or more sets of drivers may still be useless unless it provides proper bi-amping for channels 3 and/or 4. The 4 channel amp is the only product that can drive the amount of raw power needed to get the most from your speakers. HOW DOES A CAR AMP WORK?Ī 4 channel amp is used to power a set of full-range speakers, which includes a tweeter and a woofer - typically four speakers in all. If you add a second amp, the possibilities are even greater! Don’t worry if you don’t use all the channels on your amp, it’s okay to leave some speaker outputs disconnected. Front speakers with a high-pass crossover and front woofers on low-pass channels.A high-pass/low-pass component speaker setup with tweeters on channels 1-2 and woofers on 3-4.A front full-range system with a bridged subwoofer.A 4 speaker system for the front and rear.They allow you to configure different types of sound systems in your car easily. THE FLEXIBILITY AND BENEFITS OF THE SYSTEMĤ channel amps are very flexible and have many advantages over other models. If an amplifier can manage multiple speakers, it’s often referred to as a ‘4 channel’ amp even if it is only controlling two channels (2 speakers). WHAT ARE 4 CHANNEL CAR AMPS?Ĥ-channel car amps are pretty much exactly what they sound like, amplifiers that control the output of 4 separate speakers. These little amps pack a powerful punch while still being compact enough to fit under any seat or anywhere else in your vehicle. Do you ever feel like no matter how hard you try, there are some parts of driving where music just doesn’t cut it? Well if so, then maybe it’s time to get yourself one of the best mini car amplifiers 4-channel on the online market today!
