High-performance sound begins here!

With Performance Audio Kits from JL Audio, achieving great sound has never been easier. Whether you're adding audio for the first time or upgrading your boat's existing equipment, each kit includes what you need to deliver amazing sound on the water, in three easy performance stages. 

Take on one stage at a time, or two, or all three.

This Stage 3 kit includes:

  • MX300/1: Monoblock Class D Wide-Range Amplifier, 300 Watt
  • One M3-10IB-S-Gw-4 10" Marine Subwoofer Driver, White Sport Grille                         

Note: Some applications may require additional components for installation (sold separately)

MX300/1 Monoblock Class D Wide-Range Amplifier, 300 Watts!

Engineered specifically for applications where you are going to get WET!  The MX300/1 monoblock amplifier employs our high-speed NexD™ switching design to pack a serious audio punch, without straining charging systems on your marine vessel. Its tiny, cast aluminum chassis is highly resistant to corrosion, with an IPX7 water-resistance rating, making it perfect for all watercraft; PLUS motorcycles, ATV's or other utility vehicles.

Delivering a robust 160W of clean power into the included M3-10IB-S-Gw-4 10" Marine Subwoofer, they are match made in BASS boat heaven. It is also capable of solid BASS performance on a 2-ohm load delivering 300 Watts  (14.4V, 1% THD), so feel free to "Stage 4" your PAK by adding another M3-subwoofer as well. The MX300/1 also features an adjustable low-pass crossover, a bass boost EQ, variable infrasonic filter and output polarity switch.

Its dual-range input section accepts a wide range of input voltage levels, from line-level all the way to high-power speaker level signals.

The MX300/1 amplifier features a black powder-coated finish, a gasketed cover for the controls to keep things water-tight, and stainless steel hardware for durability. With the addition of an M-RBC-1 remote level control (sold separately), subwoofer output can be directly controlled from the Captain's seat.

M3-10IB-S-Gw-4 10" Marine Subwoofer is purpose-built for real-world marine duty, JL Audio's M3-Series subwoofer drivers are designed to deliver outstanding bass performance that will transform your boat’s audio system. With appropriate system setup, the addition of a subwoofer allows your smaller main speakers to be free of the burden of reproducing low frequencies. This allows your whole system to play louder and to sound cleaner at all listening levels.

Targeted towards moderate powered applications, the 10-inch, M3-10IB is designed to operate without a dedicated enclosure and features long excursion capabilities with a rugged suspension system. For best audio performance, the M3-10IB is best used with amplifier power in the 50-175 Watt range and is optimized to operate with a large volume of air behind it (at least 2 cu. ft. / 56.6 l).

Like all JL Audio Performance marine speakers historically; this newest member of the family is saltwater-rated, utilizing corrosion and UV resistant materials throughout to deliver many years of listening enjoyment.
