Things to Consider Before Buying the Best Marine Amplifiers

Investing in powerful marine speakers or subwoofer for your marine vessel will surely add to the overall music experience. Although you may have already invested in the best speakers and subwoofer, you can still enhance the music system of your boat by adding a marine amplifier. However, the question you might be having in mind is how you will know the best marine amp for your boat speakers or subwoofer. There are several factors you’ll need to think about to assist you in making a more informed choice. Read on for the things to consider before buying a marine amplifier.

1. Number of Channels

Before investing in an amplifier for your boat, you should consider the total number of channels it comes with. This is basically determined by the number of speakers and subwoofers you have in your vessel. In case you’ll be using multiple and larger speakers, including a powerful subwoofer, then you will need to choose an amp with many channels. For instance, a three channel amp would be sufficient to power two speakers and a single subwoofer. You can go for an amplifier with five or six channels to power more speakers. You may also bridge some amp channels to enhance the power output especially when powering amore powerful subwoofer.

2. RMS Power

An amplifier’s RMS power rating indicates the power rating that will make each connected speaker sound best. Higher RMS power results to better audio quality. However, you will have to consider the maximum and minimum RMS power rating for the speakers as well. In most cases, subwoofers demand higher RMS rating when compared to speakers. Thus, consider the RMS of your marine speakers and subwoofer before investing in an amplifier.

3. ​Ease of Installation

Some marine amps do not come with installation kits. If you’re not careful, you might end up buying an amp that does not have wiring or a matching installation kit. In such cases, you’ll be required to order separate installation kits. The best way forward is investing in an amplifier that comes with an installation kit that is ideal for the sea environment. In general, the installation kit should come with marine rated cables and any other necessary connectors. Also, the amplifier should be easy to install even in smaller spaces.

4. High/Low Pass Filters

Amplifiers often come with controls that allow you to take charge of the sound they produce. Some controls make it possible to keep off unfavorable frequencies, thereby reducing distortion. Therefore, you should choose an amp that has high/low pass filters. For instance, filters for high pass redirect low frequencies away from speakers and filters for low pass redirect high frequencies towards the speakers. The result is getting enhanced audio quality as a result of reduced distortion.

5. Bass Boost Functionality

If you want to get powerful bass to your subwoofer or speakers, then you should consider investing in an amplifier that has bass boost capability. However, extreme bass boost may lead to distortion. Thus, it’s recommended to balance filters for low pass with bass boost for better bass without distortion.

6. Cost of the Amplifier

Different brands of marine amps cost differently. Your budget will surely determine the brand of amplifier to invest in. However, you shouldn’t base your choice on the cost factor only. You also need to consider other factors. What you need to do is create a balance between cost and quality without compromising on either factors. Moreover, investing in costly amps does not necessarily mean that you’re getting the best amp. Some amps are affordable yet efficient. Thus, consider all other factors besides cost, but don’t overpay.

Final Verdict

Investing in a marine amp will enhance the overall quality of audio you get from the receiver. Using more powerful speakers and subwoofers without an amp will not allow you to enjoy all the benefits of your boat stereo or receiver. By getting the best marine amplifier, you’ll get more bass, better sound quality and higher volume with less noise. While the amplifiers reviewed in this article share some functionalities, each amplifier has an outstanding feature. Moreover, these amplifiers have multiple benefits and an equal share of shortcomings. Regardless of their similarities and differences, each amplifier is unique in its own way. Whichever brand you choose from those reviewed here, you’ll love its benefits. Nevertheless, remember to make your choice based on factors such as the number of channels, RMS power, and ease of installation, bass boost, and cost.
