So Many Choices … So Little Time

Trust us, we understand there are countless waterproof products on the market, but it’s our goal to make your life easy and help you make the best decision in choosing a product. This is no different for waterproof speakers for your boat. You’ve read our reviews, you’ve seen our comparison table, and now you’re still wondering, for future reference, what exactly should I look for in a waterproof marine speaker. We’ll be nice enough to give you a basic outline of the criteria we’ve used in our marine speaker review.

 Fn = Function

What will you be using the speaker for? Is it for your boat? Is it for your paddle boarding adventures? Is it for fishing? These are some things to consider. You don’t want to take a speaker with a low output to compete on a boating trip with splashing waves, noisy engines, and rowdy friends. On the other hand, if you’re looking for a marine speaker to take on a quiet fishing trip on a flat, quiet lake, 1000-Watts of unadulterated speaker juice is probably overkill.

 “Watts” In A Name?

Similarly to what we mentioned in the ‘Function’ section, the amount of Watts you’ll need is going to depend heavily on where you’ll be mounting your speakers, and under what conditions. Generally, the more wattage you have at your fingertips, the less your speaker will need to compete with the elements and outside world.

 No Need To Be So Salty!

Although we didn’t mention it first, this is paramount for any marine speaker. The last thing you need is to spend loads of money on a speaker for your boat and it gets water damaged within the first few minutes of your trip. Consider speaker options with rust-proof grilles to prolong the life of your equipment.

 Just Because….

Some additional features you might want to consider are; whether or not the waterproof speaker is portable, whether it connects by cable or wirelessly (or both), the weight of the speaker, and whether it’s buoyant – especially in portable models.

  1. Portable – Waterproof speakers that are portable are great for people who like to have their music inside and outside the boat.
  2. Wired/Wireless Connectivity – This is a matter of convenience, but can greatly increase the ease of use and overall comfort of the user.
  3. Weight – Generally the lighter the waterproof speaker, the better for the boat.
  4. Buoyancy – Especially important for the portable type marine speakers, this is a no-brainer. Whether you intentionally have your speaker floating and blasting Top 40 tunes as you sip Coladas in a water tube, or your butter fingers caused the speaker to fall overboard, buying a waterproof speaker that floats is not a bad idea – especially if it’s the portable type.
  5. Mounting & Interference – Choosing waterproof speakers with a low magnetic field can reduce the possibility of instrument interference. In addition to this, avoid mounting speakers close to compasses or magnetic instrumentation.


Now you know you don’t have to conform to the default sounds of the open water – although we know it can be quite soothing and relaxing. But you can now easily substitute the ambience with your life’s soundtrack. Nothing beats riding the open waves listening to you favorite track. With your new waterproof boat speakers, your outdoor, open-water experience has become that much better.
