Consideration of the number and placement of speakers is pivotal when adding them to your marine audio system. For instance, it is recommended that speakers be added in pairs, ensuring an equal number of right and left speakers. This will help create a balanced and immersive audio experience on your boat.
Preparing Your Boat for Installation
Gathering the necessary tools and preparing your boat is a critical step before starting the installation process. You’ll need the following tools:
-
Screwdriver
-
Wire cutters/strippers
-
Crimping tool
-
Drill
-
Hole saw
-
Multimeter
-
Heat shrink tubing
-
Electrical tape
-
Zip ties
-
Marine-grade silicone sealant
If you’re replacing old speakers, remove them carefully by unscrewing the mounting screws, detaching the wires, and sliding the speakers out of place. Additionally, when working with fiberglass, opt for screws with nuts as an alternative to wood or sheet metal screws, as they provide a more secure connection.
Installing the Marine Stereo Unit
After choosing the appropriate marine audio system and preparing your boat, you can move on to installing the marine stereo unit. Proper installation involves:
-
Choosing an appropriate mounting location
-
Securing the unit with screws, mounting sleeves, or metal straps
-
Depending on the stereo model, securing the mounting stud affixed to the rear of the stereo case with a metal fastener like plumber’s tape
-
For flush-mounted head units, using through-bolts and aircraft-grade Nylock locking nuts.
Before mounting the stereo, follow these steps:
-
Strip the insulation from the power and speaker wires and crimp connectors onto them in advance.
-
If you’re replacing an old marine stereo with one from the same brand, you might be able to reuse the existing wiring harness by simply plugging it into the new stereo.
-
In case your stereo unit didn’t include a rubber gasket, apply a bead of silicone sealant around the edges to prevent water intrusion.
Choosing the Ideal Mounting Location
The performance and durability of your stereo unit are significantly influenced by its mounting location. Before cutting a hole for the stereo unit, ensure that the space is sufficient to house the stereo’s face and deep enough to fit the back of the unit. Measure the clearance twice and verify that there are no cables or wires behind the intended mounting spot. The recommended mounting angle for a marine stereo unit is up to 20 degrees, with an additional 10 degrees of allowance for any boat movement.
To protect the stereo unit from water splashes and spray, consider affixing hinged plastic splash guards to the faceplate of the stereo. When selecting a mounting location for the input port, prioritise accessibility.
Securing the Stereo Unit
After selecting a suitable mounting location, adhere to the manufacturer’s instructions and secure the stereo unit using screws, mounting sleeves or metal straps. Stainless steel hardware is recommended for optimal protection against rust and damage, especially when working with fiberglass.
Avoid using sheet metal and wood screws in fiberglass, as they can be easily stripped out.
Speaker Placement and Installation
Achieving optimal sound quality and durability in your marine audio system is largely dependent on correct speaker placement and installation. There are two primary types of speakers: flush-mounted and box speakers. Flush-mounted speakers require cutting holes in the boat for installation, while box speakers can be installed without any modifications to the boat’s structure and offer an aesthetically pleasing factory-like appearance.
Determining Speaker Locations
Considerations for determining speaker locations include sound projection, dry areas, and minimal interference with other boat components. The most effective speaker locations usually include the bowrider area, beneath the helm, and directed towards the listeners. Installing speakers in the back on each side and in the seat base opposite the driver can also provide excellent sound projection.
In addition, if a subwoofer is desired, consider placing it in a storage locker in the stern, bow, or amidships.
Installing Marine Speakers
Installing marine speakers involves the following steps:
-
Choose between flush-mount or clamp-mount methods, depending on the type of speaker and your preference.
-
Create holes for flush-mounted speakers or drill bolt holes for box speakers.
-
Make sure the speakers fit correctly, but refrain from securing them in place at this time.
For a secure and organised installation, follow these steps:
-
Use color-coded wires to easily identify and connect the speakers.
-
Use heat-shrink crimp connectors to ensure a strong and reliable connection.
-
Use wire clamps to secure the wires and prevent them from getting tangled or damaged.
-
Apply a bead of 100-percent silicone sealant around the edges of the speakers to create a watertight seal.
By following these steps, you can ensure a professional and effective wiring installation for your speakers.
