Price Price will undoubtedly be a factor for almost everyone. Car amplifiers can vary significantly in price. With this in mind, you shouldn’t allow this figure to cloud your judgment. Instead, you should set a budget for your purchase and stick with it.

Power When attempting to find out the delivered power, you will find an RMS number. This is the root mean square power and it is exceptionally important. This figure tells you the maximum AC signal that the amp can withstand. This will usually come as a wattage number and there should be a number for each channel. Some companies will lump both channels together in one single figure, in order to make their amp look better. A 50-watt total results in 25 watts per channel.

Crossover Some amplifiers are equipped with a crossover. If you’re planning on connecting your amplifier to your car’s existing speakers, you’ll definitely want an amplifier with a built-in crossover. This will give you the ability to send high frequency sounds to the smaller speakers and the rest to the bigger speakers.

Bass Boost Some of these devices provide a bass boost function. If you’re going to be listening to a lot of hip-hop or music that features a significant amount of bass, you’ll definitely want this feature added.

Channels Multiple channels are absolutely vital, if you plan on using multiple speakers. Each channel will power a different speaker, so be sure to choose an appropriate number of channels for your particular setup.

Overall, the above factors are the most important, when choosing an amplifier. Be sure to inspect each amplifier carefully and note the above factors to help you make the right choice for your audio system.
