Built-in crossovers/crossover specifications.

There are several basic factors to check when choosing a great-sounding 4 channel amplifier: It’s important to have at least some understanding of what the specifications actually mean, what kind of power rating you need, and what you can generally expect to pay. The best sounding car amplifiers have a number of important features you should be aware of before buying. What to look for in amps with good sound quality Note that 4 channel amps are usually more compact than other models (especially class D amps). This basically just amplifies the very small signal from your stereo to a higher voltage that can drive speakers with a lot of power. These supply the amplifier transistor stages which are fed with the signal from your stereo. Both work the same way: the +12V supply is “stepped up” (increased) to a higher voltage with both positive and negative outputs. 2 channel vs 4 channel car amplifier diagramĭiagram showing the basic differences between a 2 and a 4 channel car amplifier. You need to be careful when shopping to ensure the amp you’re buying meets your needs. These types of details vary from brand to brand and model to model. Some 4 channel amps are configured slightly different than others and have additional options like bass boost or crossovers that can only be used for 2 of the 4 channels. Most today also are “bridgeable” – that is, they can be connected to drive a single speaker load from 2 channels for more power. This is useful if connecting to a head unit with only 2 channels available in order to drive 4 channels of power. Many 4 channel amps also feature a 2/4 channel input switch. They’re a bit more compact as they incorporate 4 (instead of 2) independent audio amplifier signal paths and amplifier sections. While similar, 4 channel models are built slightly differently. That’s largely related to Ohm’s law and the basics of electrical power. This is because when only 12V is available, a speaker can’t be driven with much power. This is necessary to create more power for the speakers you use. Just like 2 channel (or single-channel “mono block” amps) they contain a power supply with steps up the +12V battery voltage to a higher one. However, there are a few differences you should be aware of. The amp includes switchable white and black top plates, so you can choose the look which best matches your vehicle or vessel.A 4 channel car amplifier, as you may have already guessed, is extremely similar to most 2-channel (stereo) car amplifiers. A subsonic filter eliminates ultra-low frequencies that can muddy your sound, while the conformal-coated circuit board keeps the sound cranking when you’re out having fun.
