Skar Audio RP-3500.1D Monoblock 3500-Watt Class D MOSFET Subwoofer Amplifier

Cheap amp but amazing for the money. Good power output, takes 4 gauge wire so cheap to wire up compared to 0 gauge amps. Running 4 skar 8” subs with this and it’s pushes them no problem. Had it for a while, gets a bit hot sometimes so would suggest a fan mounted to it for good cooling! Fantastic amp

Skar are knocking out some top amps, strong build and sound.

This amp is one of those “budget but actually hits” type of pieces. If you’re trying to get solid bass without emptying your wallet, it does the job.First off, the power is legit. Rated at 1200W RMS at 1 ohm, and it actually gets close to that in real use. It’s more than enough for a daily system and will push your subs hard if everything is wired right.The bass hits strong and punchy. Not competition clean, but definitely loud enough to feel it in your chest. Perfect for a daily driver setup.Now… let’s be real:The sound quality is average. It’s not trash, but it’s not some high-end SQ amp either. This is more about loud bass than perfect clarity.The amp also runs a little hot if you’re pushing it hard for long periods. Nothing crazy, but don’t treat it like it’s bulletproof.And like always with Skar, your electrical matters. If your voltage drops, this thing is gonna act up. It’s not forgiving.Cons:Sound quality is just okayCan run warm under heavy useNot built for abuse or competition setupsNeeds decent electrical to perform rightPros:Strong real-world power for the priceHits hard for daily bassAffordable and easy to findSimple setup, good for beginnersOverall:If you want loud, affordable bass, this amp delivers. It’s not fancy, it’s not super clean, but it works and it hits.Just don’t expect miracles, and don’t wire it like a caveman. Treat it right, and it’ll treat you right.

MUY BUEN PRODUCTO, EXCELENTE RELACIÓN CALIDAD-PRECIO

If you are looking for clean and crisp sound from your door speakers this is what you're looking for.

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.

Very happy with the performance of these amps. The whole system sounds amazing. I have installed full systems in my car and my wifes.
