Features To Look Out for in a Marine Subwoofer

Ideally, you want to choose a new marine subwoofer that has an impedance of around four ohms. It would be ideal if you could find a new marine subwoofer that had a lower impedance, but this will work just fine if your new investment possesses these qualities.
A High Power Rating Suited to Your Needs
When you invest in a new marine subwoofer, you want to know that the volume is high and effective for your needs. The volume of your new marine will completely depend on the power rating that it has been given by the manufacturer. It completely depends on what you are looking for in your marine subwoofer.
