Designed for maximum power, efficiency, and durability, it features a premium 3oz PCB, a beefy heatsink for thermal management, and a remote subwoofer level control for on-the-go bass customization. Ideal for serious car audio enthusiasts seeking professional-grade sound and unmatched value. ## Description The RP-4500.1D is one of the two newest additions to the popular RP amplifier lineup from Skar Audio. It is the most powerful monoblock amplifier in the series. Designed for maximum power, efficiency, and reliability, every feature of this amplifier exemplifies its high quality engineering. This amp is rated at a conservative 4,500 watts RMS power at a 1 ohm operating load. No shortcuts were taken when designing these two high-powered additions to the RP Series; they are both strappable, and we even went as far as to include a 3oz high purity and thickness printed ciruit board. This amplifier comes with a remote subwoofer level control and bass knob allowing the user full control over their bass from the front of the vehicle. Review: Great underrated Amplifier - 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. Review: Insanity! - I like how loud and perfect this setup is, or any of my Skar setups for that matter. Just a beautiful thing. Bravo, Skar… Bravo Edit: My 4500.1 is NOT mounted to the enclosure. I fabricated a bracket and it just floats there and stays cool. The 4 EVL 12’s must be getting broken in or something because it is getting even louder! I never even found the limit when I was tuning it. I just stopped when it started to hurt my ears and threw iced coffee on my dash because it was shaking so much in the cup holder. I haven’t even ported the enclosure yet! Good grief man. Peoples reactions when they get in and hear/feel it for the first time… priceless. ## Features - MOSFET Monoblock Power Amplifier - RMS Power at 1 Ohm: 4,500 Watts - Class D Circuitry, Stable at 1 ohm - Frequency Response: 20Hz~250Hz - Remote Subwoofer Level Control Included ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0788B8YP9 | | Best Sellers Rank | #38,874 in Electronics ( See Top 100 in Electronics ) #9 in Car Audio & Video Mono Amplifiers | | Brand | Skar Audio | | Brand Name | Skar Audio | | Customer Reviews | 4.4 out of 5 stars 131 Reviews | | Global Trade Identification Number | 00011922308457 | | Item Dimensions | 56 x 21 x 6.2 centimeters | | Item Weight | 9.19 kg | | Item dimensions L x W x H | 56 x 21 x 6.2 centimeters | | Manufacturer | Skar Audio | | Material Type | Metal | | Maximum Output Power | 4500 watts | | Minimum Supply Voltage | 12 Volts (DC) | | Minimum supply voltage | 12 Volts (DC) | | Model | RP-4500.1D | | Mounting Type | Surface Mount | | Mounting type | Surface Mount | | Number of Channels | 1 | | Number of channels | 1 | | Output Power | 4500 Watts | | Package Type Name | Box | | Part Number | 43217-166536 | | Specification Met | WEEE | | UPC | 011922308457 | | Unit Count | 1 Count | ## Product Details - **Item dimensions L x W x H:** 56 x 21 x 6.2 centimeters - **Manufacturer:** Skar Audio - **Minimum supply voltage:** 12 Volts (DC) - **Mounting type:** Surface Mount - **Brand:** Skar Audio ## Images ![RP-4500.1D Monoblock 4500-Watt Class D MOSFET Subwoofer Amplifier - Image 1](https://m.media-amazon.com/images/I/61m2cGZD1CL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: I have 4 12"s will i have to install a second battery for it to push like i expect it too?** A: Always upgrade the big three first bigger wire,alternator, and battery before adding anything like one guy said capacitors are garbage they mistakenly make you think they do what you want them to do but they do not at all. **Q: Is or will it handle 0.5 half ohm running daily?** A: Highly not recommended.
