Buyer’s Guide

With such overwhelming information, you can easily get stuck and confused. Which model is better to choose? There is a set of basic rules of thumb which will help any customer to make the right decision.

Say “Yes” to the Power

First of all, the more power the amplifier has, the better it is. A lot of customers think like that. However, it is not that simple in case with amplifiers. To match your amp to your car audio system, it should be more powerful than subwoofers and speakers. But you should bear in mind such important parameters as sensitivity and impedance balance. The manufacturer provides information about them freely. All you need to do is to compare the data of an amp with the equipment you already have. Well, you can still use an amplifier and subwoofer, for instance, if their impedance levels are different. But remember you are in the risk zone. In this case, the sound achieved will leave much to be desired. Therefore, it is a must to do this investigation to avoid damages of your system’s elements.

Never choose an amplifier by its peak power. This parameter will not tell you how efficient the solution under consideration is. Keep an eye on RMS ratings.

Match an Amplifier to Subwoofers

The first thing to go over is your subwoofers. Subs come either as single voice coil or dual voice coil, commonly in 2 ohms or 4 ohms impedances, and very seldom in one or more 8 ohms. So your average subwoofer possibilities are single voice coil 2 ohms, single voice coil 4 ohms, dual voice coil 2 ohms, and dual voice coil 4 ohms. Now the number of voice coils and the impedance reflect what kinds of loads you can wire your sub or subwoofers to at your amplifier, as well as the type of wiring you choose — parallel, series parallel, or series. A quick overview: parallel wiring offers higher loads like 1 ohm which means more power. 1,200 RMS at 1 ohm and each combination of the kind are beholden to specific impedances that they can make.

Overall, single voice resolutions are not multi optional, unlike their dual voice coil alternatives. For instance, one single voice coil two ohm subwoofer can be wired to a 2 ohm load only. One dual voice coil 2 ohm subwoofer wires to a 1 ohm load in parallel and a 4 ohm load in series. So be attentive with these connections to match your amplifier and subwoofers correctly.

FAQ

Do stereo amplifiers have a great difference from monoblock amplifiers?

As we know, a stereo amplifier has two channels (left and right within the chassis), while a monoblock has just one. They are generally the same as for their size and inside-stuff parameters. In its simplest form, a monoblock has an advantage of isolation so that you are not sharing one transformer, a common power cord, and power supply amongst two channels. The differences in sound quality are pretty significant. Overall, a lot of companies make both mono and stereo versions. The latter products are convenient and sound great. However, they are nowhere near as good as mono amplifiers. On a highly resolving system, for people who actually pay a lot of attention to the way things sound, monoblocks are better than stereo amplifiers.

What is a class D amplifier?

In simplest words, it is an amplifier that works in a certain way. Class D is a whole different way of generating musical energy empowering loudspeakers. It uses something called pulse width modulation. Such type of the device takes an input wave, like a sine wave, and converts it into a high frequency pulse width modulated square wave. Then you filter the square wave and end up with an amplified sine wave on the output. A class D amplifier switches high currents at high frequencies.

Conclusion

All in all, it does not matter if you a car audio enthusiast or a pro-level upgrader, you will still need time to select the matching product with all the necessary parameters to control and adjust your system when required. With the help of our top-10 best car amps for bass, you will certainly spare your time on the research and shopping.

All the presented models belong to the budget lines. But that does not mean they are less qualitative than their up-market alternatives. Frankly speaking, even though the technologies are changing so fast, the standards are staying pretty the same. That is why spending less you can easily get more.

Enjoy the bass sound with any of the recommended amplifiers!
