Our take on the MA4-3000D 3000W Class D 4 Channels Marine Boat Amplifier

The Power Acoustik MA4-3000D is a four-channel Class D marine amplifier rated at 285W x 4 at 4 ohms, 375W x 4 at 2 ohms, and 750W x 2 bridged at 4 ohms, with a 3,000W max rating. It is conformal coated for marine use, so it is built to shrug off moisture in boats, off-road rigs and open vehicles. Class D operation and a compact Razor Series chassis make it easier to tuck into tight spaces than full-size Class AB amps. It suits boaters and off-roaders who want four channels of power without a big footprint, though the inflated max-power figure and modest real-world output put it in the budget tier against premium marine amps.

Questions and answers

What power does it actually deliver?
It is rated 285W x 4 at 4 ohms, 375W x 4 at 2 ohms, and 750W x 2 bridged at 4 ohms. The 3,000W figure is a peak max rating, not continuous RMS output.
Is it really waterproof?
No. It is conformal coated to resist moisture and corrosion, which suits marine and open-vehicle use, but it is not a sealed waterproof amp. Mount it where it stays dry.
Can it run two subwoofers?
Yes. Bridging the four channels into two gives 750W per bridged pair at 4 ohms, enough for a pair of subs wired to a 4-ohm load per pair.
Does Class D matter here?
Class D runs cooler and draws less current than Class AB, which helps on boats with limited charging. It also allows the smaller chassis.
What is in the box?
The amplifier and its mounting hardware. Speaker and power wiring are not included and must be sized to your install.
