Best Marine Speakers Product Reviews
Skar Audio SK8M 8” Speakers
This is a pair of 8-inch marine-grade speakers from Skar Audio. They feature high-quality components that are sealed from the elements. Skar builds these for serious power and with an 250 W RMS rating Skar calls “conservative”, you can be certain everyone on the water will hear you. An 8” speaker provides you with most of your midtones and some bass frequency, but you’ll be surprised at the deep, feel-it bass from these speakers. A marine-grade 1” silk dome tweeter gives you crystal clear highs and the butyl surround and a microfiber composite mineral-filled cone rock the midrange frequencies. The two-piece design helps to eliminate tonal crossover between the tweeter and the speaker to reproduce accurate sound at any volume.

Marine Speakers Buyers Guide
When you are looking to buy marine-grade speakers you need to find a product that will handle the type of boating you do. If the speakers are going on a boat that is for pleasure cruising, you’ll worry less about water resistance than on a wakeboard boat that is frequently wet. Some manufacturers will give you information on how well their product performs, usually through the IP-rating system. Higher IP-rating numbers indicate better weather resistance.
Power handling is important, but you’ll also need to factor how much power you are supplying. A factory head unit usually generates 18-20 watts per channel, so you’ll need a decent amplifier for any speaker that has an RMS value around 100 watts or higher in order to get good sound. There are a number of excellent marine-grade amplifiers available to help you rock the boat.
There are some key features you should look for. A marine grade speaker should have sealed terminals and some manner of resisting spray. All of the speakers on this list will accomplish that, with some designs being more appropriate for really wet boats than others.
How you plan to mount the speakers also matters. Some of the speakers on the market are “free-air” designs that are not intended to be installed in a box. They work better when there is no resistance behind the speaker. Other designs will require some type of an enclosure to perform at their peak. Many people who are dissatisfied with their sound system have the wrong speakers for the application.
Most sets are available in black or white, with a few products offering interchangeable grills to match your interior. A few designs provide lighting options using LED diodes. These systems can add a new level of drama to your on-water party boat.
No matter what type of boat you are outfitting, you’ll find an excellent product on this list that will meet your needs. These speakers are tested and trusted by boaters all over the world and have earned reputations for quality and durability in real-world use. You can buy a set of speakers for your boat that will give you years of enjoyment and stunning sound quality.
