Marine Amp Buyer’s Guide
Who Should Buy a Marine Amplifier
When out in open water, sound and communication are two things that are important to make the most out of each trip. And while some boat stereos work well without an external amplifier, users miss out on the ability to experience the full range of what their boat trips could get.
The first reason why you should buy an amplifier is obvious. If you’re picky about the sound quality or you want to adjust the sound, a marine amplifier is a necessary tool.
For example, a party boat with over 20 people would need a marine amplifier to get the sound to where it needs to be level-wise, but simply bein loud isn’t enough. An amplifier helps amplify the overall sound in conjunction with the volume.
It doesn’t matter if you’re a sound professional or a novice, you’ll find a marine amplifier does a lot to maximize what your boat’s audio system can do.
Important Features to Consider
There are some important features you should think about when getting your first amplifier. In regard to environmental noise, you might want to increase your power requirements (watts) to prevent from losing your favorite playlists to the elements.
It’s important to keep in mind the overall energy usage that your ideal set up will entail. Replacing fried or underpowered parts of systems is a headache that can be avoided by just being aware of wattage and your overall electrical system’s needs for balance.
Finally, don’t neglect the bass of your sound system. A separate amplifier and sub are more likely to work better for boosting the bass of your system than a 5-channel, all in one unit. So don’t forget to get that necessary add-on and invest in a high-quality subwoofer.
Frequently Asked Questions When Researching Amps
Are amplifiers bridgeable?
It depends on the model of the amp. If it is bridgeable, there will be a button that allows users to change the output to the bridgeable mode. The diagram will show you where to connect the output wires for bridging.
Are all amplifiers waterproof?
When looking for a new marine amplifier, check for its waterproof rating. If it’s at an IP07, then you’ll have an amplifier that is splash resistant, anything lower is susceptible to moisture in some form.
Can These be Used in the Car Stereo?
You can use some marine amplifiers in your car stereo, but it’s better to use it for its intended purpose due to the specificity of its design purpose at its price point.
