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.

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.
