Skar Audio engineered the RP-3500.1D 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-3500.1D. This amplifier is competition grade and for the most serious audiophiles seeking extreme levels of power output.The RP-3500.1D 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 3,500 watts RMS power at a 1-ohm load, with the capabilities of reaching beyond 5,500 watts at max power output. This amplifier is by far one of the most affordable and powerful competition grade monoblocks on the market when priced per watt, and will exceed your expectations when you hear it bring your subwoofers alive.Furthermore, the oversized 1/0-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 variable adjustment tunings for gain level, bass EQ (0-9 dB), subsonic filter (10-50 Hz), low-pass filter (35-250 Hz), and phase filter (0-180 Degrees).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. Present on the RP-3500.1D as well are both input and output RCA connections, allowing the source signal to be daisy chained between multiple amplifiers. The RP-3500.1D is also strappable, featuring an output master/slave input switch.

  • A+ Highly recommended!
Size: 3500 Watt Class D Monoblock
I bought the used option to save a little money. First amp I received was defective. I contacted Skar regarding the issue and they paid to send it back on warranty. They tested and found the RCA inputs ground shields were bad. They quickly sent me a replacement. Customer service qas A1 in my opinion. It didnt cost anything to replace it, all in all, great company to do business. They were very friendly and courteous. Would absolutely recommend Skar. ... show more

  • So much power
Size: 3500 Watt Class D Monoblock
This amp is overkill for what I needed, but there wasn't anything I found that provided 1500w at 2ohm. The dyno tests I saw hit the numbers it claimed and I figured it be better to only use half its potential to keep it cooler. Seems to work very well!

  • Great item.
Size: 3500 Watt Class D Monoblock
I was going to return it. But then I reviewed all my wore connections. The rewired just two tiny thin wires that where missplaced. Problem was solved, and boy what a sound. My hole car trembles like an earthquake is taking place inside the trunk. It is so loud that even my cloth vibrates. I am super happy with just this one amp. I hope it lasts many years. Thank you. ... show more
