Want to hear music while waterskiing, tubing or wakeboarding ? Then you need volume, and that demands a powerful marine amplifier. Alternatively, maybe you just want some soft music while chilling at the dock. It doesn’t have to be loud but shouldn’t you still hear it clearly? In both cases a quality marine amplifier is what you need. In your search for better sound make our guide to the best boat and marine amplifiers your starting point. An amplifier should let the speakers deliver crisper, sharper notes across the range and without distortion. All good amps do that, but one that’s designated as a marine amplifier is built to survive the rigors of life outdoors. Even if the amp itself is sheltered, the humidity in ocean and lake air damages unprotected electronic components. (And salt rapidly accelerates corrosion!) One effective way of boosting sound quality is by adding a subwoofer. This definitely needs an amp. You could go with a monoblock or single channel unit, or you could buy a multi-channel amp and do some bridging. Our buying guide explains these terms, helping you decide which is the best marine amplifier for your needs. Power ratings often concern amplifier buyers. Is more better, and how much is enough ? Our buying guide details RMS power ouputs for highly rated amps and explains how to match them to your speakers. When picking a good marine amplifier there are some other factors to consider too. Size, construction, the availability or a remote control, and of course class. That’s class as in amplifier class, not sophistication. It relates to electrical efficiency and heat generation. Our marine amplifier buying guide covers the three classes and highlights which we think you should choose. With a good marine amplifier music you play on your boat will sound clearer. When the engine and waves get loud it lets you crank the volume without distortion. Don’t shortchange yourself, invest in a quality unit.
