This Class D amplifier uses less power, takes up less space, and generates less heat than traditional amp designs, making it the perfect solution when space is at a premium and sound quality is the ultimate goal.

Great amp

My only complaint is how you wire up the speakers. But I fear that is the price you pay for such a bad ass little amp. Besides that I’m excited to have everything installed now and soon my little EVL6.5 will come alive. Ignore my power wire job. Forgot to put the inline fuse where it can be hidden.

Noob reviewer

Started my first audio install on my vehicle, paired with:


I like how it's compact. Fits under the seat were the original amp was. Only complaint i have is that it gets fairly hot. Kinda scary.


I have installed in a Corolla 2016 with OEM factory stereo, two Memphis mojo 6.5 with baffle foam, and two Rockville 6x9 in the rear with baffle and small square kicker 8' sounds pretty good, just got a little hot but I think is normal

I could not have been happier with this purchase!

This amp has everything that I was looking for: aesthetically flawless (this is a beautiful amp), ample power for 2 pairs of door components and a powerful sub channel (perfect for my 2 pairs of Rockford Phosgate Power component sets rated at 100W nominal each corner of the vehicle), and lastly, amplification clarity from my pair of JL Audio OEM LOC's. The crossover function on Channels 1-4 is perfect for cutting out the lows, while using the bandpass for the subwoofer Channel 5. This works absolutely perfect. This was my first Skar Audio purchase, and I am honestly hooked. Everyone that sees the amplifier, and then hears the signal, immediately follows up with a "Wow." Great job guys...I am eager to try out other products. Attached is a couple of photos of the cargo area in my 2010 Kia Soul...the "schematic" look is what I enjoy, rather than hiding all the connections, so yes, this was intentional. Enjoy, and thanks again.

Motorhome Audio Upgrade

Sk-M9005D was my choice to run audio in 31 foot class C built on a ford chassis. It’s small foot print made placement under the front passenger seat a no brainer. The amp drives 2 pair of Skar 6x8 coaxial speakers and a VD-8 sub In a custom down firing enclosure. The sound is very clean with excellent bass.
