Description

Skar Audio engineered the RP-4500.1D 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-4500.1D. This amplifier is competition grade and for the most serious audiophiles seeking extreme levels of power output. The RP-4500.1D 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 4,500 watts RMS power at a 1-ohm load, with the capabilities of reaching beyond 7,000 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-4500.1D as well are both input and output RCA connections, allowing the source signal to be daisy chained between multiple amplifiers. The RP-4500.1D is also strappable, featuring an output master/slave input switch.

  • Great underrated Amplifier
Size: 4500 Watt Class D Monoblock
After using only Sundown products for the last 7 years, it came a time when I wanted to build a budget build and Sundown was not in it. For years i've seen the massive amount of what I will now call 'propaganda' against this company which said it's products were terrible. Not only is that untrue, my experience is 100% the opposite in my limited time with it. The RP-4500 is as powerful as you would expect a 4500w rms amplifier to be, it has lots of power. For an amplifier that does not include an internal fan to keep cool, the beefy heatsink does a wonderful job even in hot sun of keeping the amp within temp on near clipping load for over an hour. Sound quality wise it is no different than the most expensive sundown amplifiers or the least expensive down4sound amplifiers, in my experience. Budget wise it provides one of the best price per watt ratios in the amp market right now. Very happy with this purchase. What I think could make this board better would be to include a clip indicator knob and maybe a cooling fan. A foam gasket around the back panel of the amplifier would be great to reduce vibration induced noise/rattle. Sundown audio amplifiers for example include this gasketing. ... show more

  • Big sound little package. But didn't last
Size: 350 Watt Class D Monoblock
The sound quality that this Amp had was amazing. Leaps and bounds better than the 10 year old Amp that it replaced. But it was very short lived. It lasted 5 days and has developed a direct short to ground. Update* scar sent a shipping label and are going to verify the problem then send another amp once they've verified the failure. Fun fact, they offer a 2 year warranty. I'd rate the seller high but I'm going to wait until I receive and test the replacement Amp before I update the review. Update: skar sent another amp and once again....this little amp out performs the Blaupunkt 750watt amp that I was using for a backup while I was waiting on skar to send another amp. Wow. I may be asking too much for this Amp now but it's pushing 2 punch p1 10s quite well. But I do believe that I'll be upgrading to a larger skar amplifier in the near future. The customer service has been amazing and they have definitely earned a repeat customer here. ... show more
