RP-350.1D | 350 Watt Monoblock Car Amplifier

  • Skar Audio engineered the RP-350.1D Class D monoblock subwoofer amplifier to be dominant in both power and reliability compared to anything else on the market in its' class and physical size. 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 this unit. The smallest of all RP series amplifiers, the RP-350.1D is the perfect solution for when you need versatility but are not willing to sacrifice power output.

    The RP-350.1D is 1-ohm stable and utilizes a wide array premium internal components that make it extremely powerful and reliable - such as its high speed MOSFET power supply and advanced PCB board layout. Conservatively rated at 350 watts RMS power at a 1-ohm load, with the capabilities of reaching beyond 388 watts at max power output. This compact, small footprint amplifier, is by far one of the most affordable monoblocks we have ever released, and is great for powering a pair of subwoofers rated around 200 watts RMS each or a single subwoofer around 400 watts RMS.

    In addition to all of the above features, the 8 gauge power and ground terminals found on the amplifier allow for maximum current flow and therefore higher power output and more efficient operation. Furthermore, 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.

    Featuring 4-way protection circuitry, you'll have the peace of mind knowing that you are protected against damage to the amplifier for various reasons - including electrical shortage, over heating, low voltage, and more. This amplifier comes with a remote subwoofer level control (bass knob) allowing the user to have full control over their bass from the front of the vehicle.

Skar audio Rp 350.1

Great amp makes my IX 10's hit really hard, sounds amazing, never gets hot, and skar is always my go to shop for anything car audio related great stuff


Awesome. Best amp i have ever owned. I used to push two 8 inch Skar woofers. They are 300 watts a piece. I have to lower the amp because it has a lot of power.


Maybe it's just my car or the audio installers but I purchased this amp with the sdr8" loaded sub enclosure thinking it would hit.
Sub is barely moving and although the sound quality is crisp, I'm missing the bass everyone promised it would produce. Extremely disappointed overall.

Awesome Amp!

Its been a long while since I have bought an amp. I came across this amp from ads and friend recommendations. So I decided to buy one to "test". Once I got it installed (stock deck) and ran some tests I am very very very satisfied!!! I love this amp even though I am running 1 10" JL Audio 4ohm. It pounds! Good job Skar on this amp!

Great Little Amp

Bought this for a budget build for my daughters 2002 Mustang convertible to run 2 IX12's and am very pleased with it. Need a better box that the one that was in the car when we got it but it all works great so far.
