Skar Audio SK-M5001D Compact Monoblock Class D MOSFET Car Amplifier, 500W

I ran this mini 500W amp through my tests including RMS Power output tests using the SMD Amp Dyno. The little Skar amp performed as advertised, no surprises. Skar has an Amp Dyno as well and confirms their ratings with all of their amplifiers. See the attached image of the Amp Dyno results if you're interested in the numbers. You can also see the size comparison to the Sundown SAM-500D, which is not only quite a bit more expensive, but also has the marine coating on the board (whereas the Skar does not). That said, I'd be careful using this Skar SK-M5001D in any environment where getting wet is a possibility. It's better suited for small spaces inside the vehicle. The amp powered the custom 600 watt 12" subwoofer (D2) in the acrylic enclosure with no issues. Sound was deep and dynamic with plenty of output. I also had a technician review the internal components and minus the old design of the driver card with known overheating problems, the amp was given a passing rating. Overall great value for the money. Dereck from Williston Audio Labs

Bought this to go with Skar's 10" Toyota Tacoma sub box (with included sub) and it powers it great. Installation was easy and straightforward. Doesn't get hot, small size - easy to install basically anywhere, and best of all it is 1 ohm stable (like their sub requires). Only owned and had installed for 2 weeks so if there are any issues I will update this review

Scar is a great brand. I’ve had several amps from scar and subwoofers right now I’m using the 500.1 to power a kicker comp 12 and it absolutely slams. The 2 A I had before were kicker 1200.1 I had those pushing to EVL 12s one each never had a problem with any of my scar equipment even the scar 6 1/2 two ways I have in my doors great sounding speakers

Nice amp except for the broken bass knob. Power light says the knob is on but there's no response from the amp. The wire for the knob was weirdly bunched in the box when it arrived also.

This amp is awesome! Had a defective bass knob with the amp but didn't affect the performance. Contacted them and they had a new bass knob and wire sent to me free of charge and fast! The knob works great and I can now adjust the bass at full range. The amp does get pretty hot when using it for awhile but hasn't gone into protection mode yet. So we will see. Thanks again

I am on my second amp, having returned the first for heating up and going into protect. The second does the same thing. I am only getting about 10 minutes of listening time before it shuts off. I have tested on a 2 and 4 ohm load and it shuts off with both, and it does not matter if the music is bass heavy or not. Very frustrating because it sounds amazing, when it works. I have the amp mounted with plenty of airflow around it. UPDATE- I added a small fan and the amp worked great, until there was a loud pop and smoke began pouring out of the amp. I was listening to a podcast when it occurred, nothing bass heavy. I had to pull the fuse on my distribution block, the protect mode on the amp did not cut power. Please do not buy this.

I'm very impressed in the power this mini amp has its true to its 500 rms, it is very very small but don't let that fool you. I'm running this at 1ohm to my 12 inch skar 500 rms subwoofer and it absolutely pounds in my ram 1500 , great price, can't beat this amp.

This was the absolute best amp I’ve ever owned ! Unfortunately when I got into a car accident I wasn’t able to take my AMP out due to it being mounted to the back of my seat . So if you think about mounting this to your seat , I wouldn’t . I would use double sided Velcro instead. Because I am so upset I didn’t get to take this out . This is by far the best, I highly highly recommend this AMP as I’ve had it for a few years. I love being able to have access to the different channels on the side .

Awesome little amp. Very stable signal. Tuned with an oscilloscope to match my sub.
