Product Features
Engineered for harsh marine conditions
With a marinized circuit board, stainless-steel hardware and all the right waterproofing, the MA6004 is, like all JBL® marine audio products, built to survive salt water, corrosion and other risks – and show you a great time out on the water.
Tuning options for systems of any size
The JBL® MA6004 has onboard 12dB electronic crossovers, giving you tuning options for systems of any size. Versatility, convenience and ease of use are all part of the JBL way of sound.
Optimize performance in any location
Your boat may give you a choice of where to install your sound system, or it may not. Fortunately, the MA6004’s variable bass-boost circuit provides additional bass tuning to optimize performance, regardless of where it lives.
Easy installation in tight spaces
Owning a boat takes commitment and work. Installing the JBL® MA6004? Not so much. It’s also pretty compact at 13-1/4" x 10-1/4" x 2-3/16" (337mm x 261mm x 56mm) with a low-profile heatsink. You can put it in some very tight spots.
Big, dynamic power
The JBL® MA6004 has output of 60 watts RMS X 4 channels at 4 ohms. You can fill the fresh, open air with great sound.
