RP-1500.1DM | 1,500 Watt Monoblock Marine Amplifier

  • Skar Audio engineered the RP-1500.1DM marine amplifier to be unrivaled in both performance and reliability compared to anything else on the marine market its class. Designing the most efficient, well built, high quality amplifiers is where we start here at Skar Audio, and that is exactly what is delivered in the RP-1500.1DM.

    The RP-1500.1DM is 1-ohm stable and utilizes a wide array of premium internal components that make it extremely powerful and reliable - such as its high speed MOSFET power supply and advanced, marine grade, PCB board layout. Conservatively rated at 1,500 watts RMS power at a 1-ohm load, with the capabilities of reaching beyond 2,300 watts at max power output, this amplifier is great for powering the sub stage on your boat/UTV.

    Furthermore, the oversized 4-gauge power and ground terminals found on the amplifier allow for maximum current flow and therefore higher power output and more efficient operation. You'll have full reign over your amplifier with the built-in user control panel, featuring a bass EQ switch (0, +6, +12dB), and variable adjustment tunings for gain level, low-pass filter, and subsonic filter.

    In addition to all the above features, this model also features 4-way protection circuitry, which will give the user the peace of mind knowing they are protected against damage to the amplifier for various reasons - including electrical shortage, overheating, low voltage, and more. Our marine amplifiers feature a special marine coating internally that allow them to withstand the harshest conditions for long lasting use. This amplifier comes with a remote subwoofer level control (bass knob) allowing the user to have full control over their bass from anywhere on the watercraft.

    RMS Power @ 1 Ω 1,500W x 1 Ch (14.4v)
    Peak Power @ 1 Ω 2,300W x 1 Ch (14.4v)
    Power & Ground Input Size 4 Gauge
    Remote Bass Knob and Cable Included Yes

Superb products that aren't overpriced.

I am a huge fan of Skar Audio, great products that are fairly priced. Shipping is super fast and although I have never had to contact customer service because none of their products have ever given me any issues I heat that they are great. Highly recommended!!


This is my second 1500 watt marine amp. Very happy with the way it performs. Purchased this second 1500 watt marine amp to run 2 skar shallow mount 12s, along with the other 1500 watt marine amp running 15s. Also have the 4 channel 1000 watt marine amp. Very pleased with it's performance. Thanks SKAR AUDIO!!!

Skar RP 1500

Love the Amp.. It amplifies The lows so you can feel and hear it..


I hooked the amp up to a 400w (well known brand) 12" sub and after about 4 songs I blew the sub. Lol. I knew it was going to happen. It took me about 10 minutes to order a DDX-12. I haven't received it yet but I'm looking forward to getting it installed and bumping it!

Marine amp

I love this amp so far. I haven’t got to put it on my sxs yet. But I installed it in my truck to try it out on some subs and it sounds great and very powerful!
