Key Features:

• Free Air Design:
  No enclosure needed! The RM-PREMIUM104 delivers powerful bass without the constraints of an enclosure.

• Quality Construction and Materials:
  This sub uses a Polycarbonate Cone which is not common for a marine sub at this price point. This is a much more expensive material which has extreme advantages over a typical Polypropylene cone for a marine environment. Polycarbonate is an excellent material due to its combination of durability, resistance to environmental factors, favorable acoustic properties. It is also a light-weight material that is strong and this means it will give the subwoofer a higher sensitivity rating which means it will play really loud even with an under-powered amplifier. These characteristics make it well-suited to withstand the harsh conditions of marine environments while providing high-quality sound performance.

• Impressive Power:
  With a maximum power of 1200 Watts and an RMS power of 300 Watts, this subwoofer packs a punch.

• Voice Coil:
  The 2.0″ 4-layer voice coils are extremely durable and high quality. They are specifically engineered to withstand marine applications. This is the dual 4 ohm voice coil version but we also have a dual 4 ohm available.

• Waterproof and Strong Basket:
  The molded ABS plastic basket, formulated with a special blend, is both waterproof and unbreakable. It can withstand even the toughest marine conditions.

• 40 Oz Magnet:
  The single 40 Oz magnet provides robust magnetic force for accurate bass reproduction.

• Vibrant RGB LED Lighting:
  Choose from 21 colors and 21 flashing patterns to create an eye-catching marine audio setup. Adjust the speed and brightness to suit your mood.
