Know before you buy
These speakers are rated IPX5 from the front, meaning they are designed to withstand water jets and spray. While they are built for harsh marine environments, they are not intended to be submerged.
Yes, the integrated RGB perimeter illumination requires a compatible external LED controller to change colors or lighting modes. Without a controller, the LEDs will not function.
Yes, these are standard 3-ohm speakers that work with most marine head units or external amplifiers. However, ensure your amplifier is stable at 3 ohms to get the best performance from the 100W RMS power handling.
The speakers are specifically engineered for marine use with UV-resistant materials and corrosion-resistant hardware. They have undergone rigorous salt spray testing to ensure they won't degrade or rust when exposed to harsh coastal conditions.
The speakers come with corrosion-resistant hardware included, which is designed to hold up against the elements. You will only need standard wiring and tools to complete the installation in your boat's existing cutouts.
The 3-ohm impedance is designed to extract more power from your amplifier compared to standard 4-ohm speakers. This helps achieve higher volume levels and clearer sound, which is essential for overcoming wind and engine noise on the water.
