Description

Skar Audio engineered the RP-1200.1D Class D monoblock subwoofer amplifier to be dominant in both power and reliability compared to anything else on the market in 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-1200.1D. The RP-1200.1D 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 1,200 watts RMS power at a 1-ohm load, with the capabilities of reaching beyond 1,600 watts at max power output. This amplifier is by far one of the most popular and affordable mono-blocks we have ever released, and is great for powering a pair of 600 watt rms subwoofers or a single 1,200 watt rms subwoofer. 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. 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-1200.1D Review: Bringing My System to Life
Size: 1200 Watt Class D Monoblock
I recently upgraded my car audio setup with the Skar Audio RP-1200.1D Monoblock Class D MOSFET Amplifier, and let me tell you—this amp is a game changer. I paired it with two Sony Xplod 1200W subwoofers that have been in my family for years, and somehow, in 2025, they’re still hitting like they just came out of the box. This amp truly unlocked their full potential, delivering clean, hard-hitting bass that shakes the trunk in the best way possible. The RP-1200.1D doesn’t just claim power—it delivers it. From deep, rumbling lows to tight, punchy kicks, the output is consistently powerful and distortion-free, even when pushed hard. And for the price? It’s an absolute steal. You’re getting serious wattage and reliability without breaking the bank. Beyond just bass, I also have two JBL Concert Series speakers in my front doors, and the clarity is breathtaking. Whether it's crisp highs, smooth mids, or deep lows, my system now has a perfect balance between power and precision. The combination of Skar’s raw power and JBL’s crystal-clear detail has completely transformed my listening experience. If you’re looking for an amp that delivers serious power without draining your wallet, the Skar Audio RP-1200.1D is an easy recommendation. It’s proof that you don’t need to spend a fortune to get rich, room-filling sound that makes every drive an experience. ... show more

    • Throws hard punches but is NOT GOOD for LOW HZ
Size: 1200 Watt Class D Monoblock
EDIT: I gave this one more star due to the fact this amp does work well and does last. Its a good build quality I did not expect from SKAR. I have used it every day (almost) for the past 9 months, often at near full volume with everything vibrating and flexing, paired with ONE Sundown SA-12. I still stand behind my statement about this not producing very low Hz like I was used to with my old class A/B amp, and it is absolutely noticeable on certain songs. I have done many low Hz tests and this amp just does not hit certain ones. It does get extremely loud though and hits well. That being said, its still a great amp and was built to last under above average consistent usage. I purchased this amp to replace my vintage KOLE Audio amp and wired it to one Sundown SA-12. The SKAR 1200 has very "punchy" bass but does not get very low. My old KOLE amp that had half the power of this hit lows soo good and you could feel the low bass. With this SKAR you do not get that at all, I am very disappointed. For that reason I may be returning this. The only difference I can see is the old KOLE is a CLASS A/B and this SKAR is a CLASS D. Not sure if that has anything to do with my loss of lows but it should not. I have everything tuned correctly and it still misses the low HZ. Back to square 1 now. Any suggestions? All in all this is a decent amp that has power, but if you want something that gets low and has clarity keep looking! ... show more

    • Nice Amp
Size: 1200 Watt Class D Monoblock
I purchased this amp to pair with 2 12 inch Skar subs, so far so good. Amp was easy to install, functions well and has plenty of power. I did notice the amp gets quite warm when run for a while so I recommend pairing up a cooling fan. I believe this amp is a great value for the cost.
