Introducing the Rockville RM-PREMIUM102 BLACK Marine Boat 10" Free Air Subwoofer with RGB LED! Crafted with precision and engineered in the USA, this subwoofer is a remarkable upgrade over our previous series.
Upgrade your marine audio experience with the Rockville RM-PREMIUM102 BLACK Marine Subwoofer – where power, style, and durability meet the open waters!
Key Features:
- Free Air Design:
No enclosure needed! The RM-PREMIUM102 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 2 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.

Description:
The all new dB marine series of amplifiers gives you the best of both worlds! We took the sound of our best selling series of dB car amps and we added the best marine grade parts so that they will last and withstand even the harshest conditions on the water.
We went a little overboard (no pun intended) to make this amp marine ready. We conformal coated the PCB board with a waterproof glue that is painted on to protect the circuitry. We then added waterproof silicone covers over the terminals so that water can never get into the amp. The heat sink, including the bottom plate, is made of aluminum which is rustproof. The end panels, all of the internal mounting screws and hardware of the amp are made of stainless steel and are rustproof as well. Even after many years of use the amp will be rust free and operate like new!
The dBM13 is a mono amplifier with 3,000 watts peak output and 750 watts certified RMS dyno-tested rated power at less than 1% THD. Here at Rockville we offer the best value in marine audio. We therefore want to make it easy for you to compare our products to any brands on the market. The peak rating can be used to compare with brands who use peak ratings such as Boss and Power Acoustik while the Dyno Certified RMS rating can be used to compare with top brands such as Kicker, Rockford, Alpine, etc.
One of the tricks to determine the real power of a marine amplifier is to multiply the fuse rating by 10 to determine the true RMS power. This formula almost always works within 20%. The dBM13 features a Maxi fuse with a rating of 80 Amps.
This amp has a fully adjustable 12dB/Octave crossover with differential circuitry. Other features include a subsonic filter, a fully adjustable bass equalizer, mute and delay soft start technology, a phase control switch, and a dashboard subwoofer control for added convenience. The dBM13 is protected by a full IC controlled circuit and has professional peak limiter circuitry guaranteeing distortion free music playback at all levels.
These amps are the best sounding out of any series we have ever created. We created them to be 2 ohm stable which is great for marine applications that use 1, 2, or more subwoofers.
We are so confident in your satisfaction of this amplifier that we will offer you a 30 Day money back guarantee. If this amp does not perform as well as you expected, we will send you a pre-paid shipping label and give your money back. This means that, if for any reason you want to return the amplifier for a full refund within 30 Days, you can! (Amp must be complete along with the box).
