Description:

The MS10LB 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 MS10LB is 2,400 watts peak, 1,200 watts Program RMS and 600 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 80 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 MS10LB 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 MS10LB 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 MS10LB 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 KTA-30MW:

PRODUCT OVERVIEW
With Alpine’s exclusive technology, Dynamic Peak Power (D.P.P.), the KTA-30MW is sure to deliver powerful bass output for subwoofers used in those open cab vehicles and toys.

A TOUGH MINI AMP THAT PACKS A PUNCH
Get big amp performance in a compact, resilient package. With Alpine’s exclusive technology, Dynamic Peak Power (D.P.P.), the KTA-30MW Weather Resistant Tough Power Pack is sure to deliver powerful bass output for subwoofers used in those open cab vehicles and toys.

This small and efficient amplifier can be installed with an aftermarket or factory head unit while adding up to 600 watts of D.P.P. power. Its weather resistance makes the KTA-30MW a good choice for use in exposed installations like side-by-sides, boats, open-top vehicles, and motorcycles saddlebags.

A SOUND SYSTEM BOOST WITHOUT THE BIG SPACE COMMITMENT
The KTA-30MW is perfect for when you want to add subwoofer power but don’t have the space for a large amplifier. It is compatible with an aftermarket or factory head unit and provides up to 600 DPP watts to the subwoofer of your choice.

DYNAMIC PEAK POWER
The KTA-30MW features Alpine’s exclusive Dynamic Peak Power (D.P.P.) technology which intelligently adjusts the gain to automatically adapt to musical needs. D.P.P. prevents the amplifier from clipping music signals by supplying up to double the power to support power hungry, rhythmic peaks like a snare drums, trumpets, or high-hat cymbals.

During these dynamic musical passages, D.P.P. instantly delivers bursts of power to rise to the peak demands of the music and very quickly rolls back down to maintain its efficiency.

WEATHER RESISTANT FORMAT
The KTA-30MW is ready for your adventures. It is weather resistant, rated at IP66 for protection again dust ingress and high-pressure water spray. Its rugged chassis and high-quality waterproof connector can be used in installations where it will be exposed to the outdoor elements.

HALF THE SIZE OF OUR SMALLEST TRADITIONAL AMPLIFIERS
The KTA-30MW measures just 9-3/16” (W) x 1-5/8” (H) x 3-3/4” (D), so its small footprint lets it fit where most amplifiers won’t, like under the dash or in the glove compartment, installed under the dash of a side-by-side, placed in the saddlebag of a motorcycle, or used in other places where space is an issue.
