Buyer’s Guide

Factors to Consider while Buying Marine Amplifiers

When looking for the best marine amplifiers, there are some specifications that will be ultimately helpful. If you are familiar with car audio, most of them will be familiar but it is important that we still discuss them to give you a better idea on how to pick a great amp. It is also important to note that we considered them in picking the items on our list.

Construction

One of the most important things to consider when shopping for a marine amplifier is how the item is constructed. You need a sturdy amplifier that will withstand exposure to the elements unless it is going to be housed in a compartment. In any case, it is important to buy amps that are solidly made and are likely to be durable so that you won’t be back in the market in the near future.

Channel

It is important that you consider the number of channels an amplifier has before buying it. Depending on the number of speakers and subwoofers you need to power, pick an amplifier with the right number of channels. Though it is possible to power any amount of speakers and subwoofer with an amplifier of any given number of channels, it is better when every speaker/subwoofer have their dedicated channels on the amp. Another rule that can work best for your marine sound system is to get an amplifier with even-numbered channels for a sound system with even number of speakers and an amplifier with odd-numbered channels for systems with subwoofers.

Bridging

Bridging is a concept that applies to multi-channel amplifiers. It is important when you need to use a subwoofer and want to give it more power. Also, when you have more channels than speakers, you can equally bridge two channels so that their power is combined to deliver more power to a single channel.

Wattage

Every speaker has a range of wattage it can cope with and it is important that you pay attention to the number of wattage your amplifier will be feeding the speakers to make sure that it isn’t too much for them.
