Know before you buy
An IPX7 rating means these speakers are fully waterproof and can withstand immersion in water up to one meter deep for up to 30 minutes. This ensures they will perform reliably even when exposed to heavy spray, rain, or accidental submersion on your boat.
The switchable 2 or 4-ohm impedance allows you to optimize the speakers for your specific amplifier. This flexibility ensures you can extract the maximum power and efficiency from your marine audio system without needing to replace your existing amp.
Yes, the RGB LEDs require a compatible external lighting controller to change colors and patterns. The speakers come with the wiring for the LEDs, but the controller is sold separately.
Yes, they are specifically engineered for marine use and are saltwater safe. The materials, including the UV-resistant grilles and durable polymer cones, are designed to resist corrosion and degradation caused by harsh marine conditions.
Plus One technology increases the surface area of the woofer cone compared to standard speakers of the same size. This larger cone area moves more air, resulting in deeper, more impactful bass performance.
These are standard 8-inch marine speakers, but you should always verify your boat's mounting depth and cutout diameter against the product specifications before installation. While they fit most standard 8-inch openings, checking your specific mounting location is recommended.
