This subwoofer has a 12-inch diameter, which is approximately 300 mm.

Yes, this product is designed to be water-resistant and suitable for marine environments. However, it must not be submerged or exposed to high-pressure water jets.

This subwoofer has an impedance of 4 ohms.

Yes, professional installation is recommended. Installation requires appropriate tools and safety equipment.

Do not install this product in an engine compartment or any other area exposed to extreme heat. It must also be securely fastened to prevent damage or injury under harsh conditions.

To clean this subwoofer, use mild soap and rinse it only with fresh water.

Yes, this subwoofer features an optional integrated RGB LED lighting system. The LED functionality requires a separate 12V wiring connection at each speaker location.

RGB LED lighting requires a separate 12V wiring. Individual wires can be wired to produce up to seven fixed LED colors. For adjustable color and effects control, an RGB lighting controller is required and sold separately.

For adjustable control of RGB LED lighting (color changes, effects), you will need an RGB lighting controller, which is sold separately. Without a controller, you can achieve up to seven fixed LED colors by wiring the individual wires.

You must install a fast-blow inline fuse on the positive wire, at the power source end of the LED cable to protect the LEDs and the speaker from excessive current. For the M7-12IB model, the fuse rating is 750 mA.

For fiberglass with a thickness of 0.125 inch (approximately 3.175 mm) or less, a pilot hole of 1/8 inch (approximately 3.175 mm) is recommended. For fiberglass thicker than 0.125 inch, a pilot hole of 9/64 inch (approximately 3.57 mm) is advised.

Yes, the suffix 'IB' in the product name (M7-12IB) indicates that it is optimized for infinite baffle mounting applications, meaning it is designed to be installed in a large air volume, such as a boat bulkhead, without requiring a dedicated sealed enclosure.

Before any installation, you must turn off the audio system and disconnect the battery of the audio system. It is also crucial to check for any potential obstructions behind the mounting surfaces before making any cuts or drilling.

Without a separate RGB controller, you can wire individual wires to achieve up to seven fixed LED colors. The specific colors depend on wiring different combinations of wires (typically red, green, blue, and their combinations such as cyan, magenta, yellow, and white).
