Skar AudioRP-150.4AB 1,000 Watt Full-Range Class A/B 4 Channel Car Amplifier

I’ve had this Amp installed for at least 4 months. This little thing is powerful and reliable, it’s in my cars trunk and it works even in the worst heat and never go to protect mode ( I haven’t abused it with sustained max volume in this 100° heat though, that wouldn’t be smart). Now I know I can trust Skar Audio.

Perfect if you have limited space in your vehicle. 2 weeks in and I have no complaints

Got this amp running two skar dvc 8's in a sealed box and they hit hard and sound great.. no clipping or distortion at all

Needed a small amp to go with a Pioneer 12" for my wife's car. It's the same sub I have in my car, both in sealed boxes, but I have a Kicker 300.1 amp in mine.This amp is small compared to the Kicker. About 1/3 the size. The bigger terminals don't like smaller wire, so I had to fold the ends over and solder them even on the remote turn-on wire.Don't get me wrong, it puts out plenty of thump, especially for the money. But it's not quite as crisp and doesn't hit as hard as the Kicker. I mean, I was able to rattle the windows in the house with some DJ Magic Mike. Everyone came out of the house when it was cranked. Just those lows are missing some life. At the same time, playing some death metal hits hard but like I said, it's missing that crispness. When tuned, there's no distortion muddling the sound.If you just want to add some bass that you can feel and sounds decent, it's a great little amp. But it's also not a high quality audiophile amp if that's what you want. I'll give it four stars only because it's not a five star amp. Outside of that, nothing would stop me from recommending it to someone.

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.

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.

It worked great until one morning the sound was massively distorted and there was a huge amount of bass coming over the speakers. Finally figured out the hi pass filters had failed. Turned filters off and sound was great again. Unfortunately without the filters active the sound is wrong for door speakers.

Received a new amp. Hook it up and it goes into protect mode for two seconds, then powers on. But puts out very little power. Contact skar customer service, they run me through tests and all checks out but amp still goes into protect mode. Send the amp in, they send it back with no communication. Same problem. They send me a new amp, same problem. I hooked it up in my other vehicle that's running a Kicker amp for years and the skar goes into protect mode. I ask for a refund on my NEW amp they just sent me and Skar says "sorry, you're out of the 30 day return window". I just got the new amp 2 days ago!Amazon to the rescue! I tell them what's happened and they allowed me to return the amp.
