Description:

The MS12LS is one of the most powerful marine subwoofers on the market. What really makes this sub stand out is the sound quality and durability. It goes so loud that if you crank it up, boats that are thousands of feet away can feel the bass. The frequency range of these subs are so good that it will make all your songs sound so much better! These play frequencies that normal full range speakers cannot hit, adding depth and richness to all your music.

The MS12LS is 2,800 watts peak, 1,400 watts Program RMS and 700 watts CEA Rated! This sub is CEA-2031 compliant, which makes it easy to compare this subwoofer to other CEA compliant subs on the market. The issue in the marine audio world is that there are so many different brands with different standards on how they rate their products. We want to make it easy for you to compare our products to any brands on the market, therefore we provided all 3 ratings for you to do so. The CEA compliant rating, which you should use to compare this to other premium brands that make CEA compliant products such as Kicker, Rockford Fosgate, Kenwood, Pioneer, etc. We also supply a program RMS rating that has become standard for many good brands in the industry such as Hifonics, Earthquake, etc. Lastly, we also supply a peak rating which almost all brands in the industry provide. This peak power is the amount of power the sub can handle for a short burst.

This subwoofer has a double-stacked 100 Oz magnet! They are twice as large as almost any other marine sub on the market, which is why these can handle so much power. In addition, the MS12LS has a fantastic sensitivity rating at 90dB, which means even if you have a smaller amplifier, the subwoofer is sensitive enough that it will still sound great.

The MS12LS was designed in a molded ABS plastic basket that is made with a special blend that is waterproof and un-breakable. You can literally jump on it and hit it with a sledgehammer without it breaking!

Using only true marine grade components and materials, the Rockville MS12LS subwoofers are fully marinized against salt & fresh water conditions. These subs are completely waterproof and protected from the elements! They are UV treated and have a special waterproof coating to prevent water damage. These subwoofers also come with a 1 year warranty to give you the peace of mind you deserve when purchasing from Rockville!

Description of DBM12:

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 forever 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 dBM12 is a class D mono-block high power amplifier with 2,000 watts peak output, 1,000 watts RMS output, and 500 watts CEA-2006 rated power. All of the mono amplifiers in the dB series are 2 ohm stable. 2 ohm stable is perfect for marine applications because most marine subwoofers are 4 ohm. This amp matches up perfectly if you have (1) or (2) subs that are each 4 ohm. They are all CEA-2006 compliant, which makes it easy to compare this amplifier to other CEA compliant amps on the market. 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. So we provided 3 ratings for all of our amplifiers. We provided a CEA compliant rating, which you should use to compare this amplifier to other premium brands that make CEA compliant products such as Kicker, Rockford Fosgate, Kenwood, Pioneer, etc. We also supplied an RMS rating that is not CEA compliant, but has become standard in the industry. You should use this rating when comparing with ratings from brands such as Hifonics, Earthquake, DB Drive, etc. Lastly, we also supply a peak rating which almost all brands in the industry provide. This peak power is the amount of power the amp puts out at the loudest moments during a particular song.

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 dBM12 features a Maxi fuse with a rating of 60 Amps. Although we rate these conservatively at 500 watts CEA @ 2 ohms, this amplifier puts out more power than this!

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 dBM12 is protected by a full IC controlled circuit and has professional peak limiter circuitry guaranteeing distortion free music playback at all levels.

The dB marine amps by Rockville use the top parts and components recommended by Rockville’s very own engineer. These amps are the best sounding out of any series we have ever created. They perform more efficiently resulting in even more dB of sound. We created them to be 2 ohm stable just like the world’s most famous amps by Rockford Fosgate, Kicker, etc. If you compare our amp to the most famous amps you will find our amp can compete and, in my opinion, surpass the performance of anything in its class.

We are so confident in your satisfaction of this amplifier that we will offer you a 90 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 90 days, you can! (Amp must be complete along with the box).

Rockville's exclusive Professional Marine Installation Kit features top of the line accessories which have been specifically engineered to withstand the toughest of marine environments. You will hear the difference and we guarantee you will not be disappointed!

Rockville Marine Audio Interconnect cables are specifically engineered to withstand the challenges of both salt water and fresh water marine installations. The utilization of tinned Oxygen Free 100% copper conductors with polyethylene dielectrics in a twisted-pair arrangement optimizes noise rejection. The small-diameter white PVC jacket is ultra-flexible enabling our cables to be easily routed around bends and through tight spaces. Our exclusive molded connector features a water proof inner cap that is heat shrunk in place over all solder connections thus guaranteeing a completely water proof and corrosion resistant connection. The locking plug design with split pin technology further insures tight connections that will not vibrate free even during the most extreme boating maneuvers.

Our Marine Grade Speaker Cables are engineered for maximum signal transfer with minimum impedance loss. The cable strands are all individually tinned, fine-strand, oxygen-free copper with aluminum composite construction and provide a high-fidelity speaker connection that is especially engineered for the marine environment. Woven down to a flat shape, the cables can be easily routed throughout the bulkhead with ease.

Rockville Marine Power Cables feature strands which are all individually tinned, fine-strand, oxygen-free copper with aluminum composite construction corrosion resistant and marine-ready. Fine-strand construction and soft PVC jacket deliver excellent flexibility. Our marine cables are much better quality than standard CCA wire kits. These kits have a very generous amount of copper in them. They are very similar in quality to the best brands kits on the market. The thickness of the wire is true-gauge. We have seen other brands who use thick plastic but very little copper inside the wire. Rockville wires are honest, true-to-spec and will make your music sound great.
