SK-M5001D proves good things come in small packages!

this amp is amazing. fits in the palm of my hand. hooked it up in friends audio a4. running 1 12 inch NVX nsw122v2 IN 1.25 CU FT sealed box. amp is running 500wx1@1ohm. we dyno tested it and it put out 486w rms@1 ohm at 14.14volts let me tell you these little amps are amazing.. it is so small it can fit anywhere. hookup was a breeze and I like that it uses only.1 hex key for all wires. amp doesn't get hot and does the power it says it does! for the price and size and power it cannot be beaten. if you are thinking about getting one, don't think about it just do it knowing you will be pleasantly surprised and do it now before the price goes up. this to me is undervalued. Only thing is that I wish it could accept 4 gauge wiring and 12 gauge speaker wire, but nothing some wire gauge reducers and speaker connectors can't fix.

Great option for smaller cars/backing up a stock radio

I got this amp to power an IX-8 sub on the rear deck of a Audi A4. I needed an amp that would fit inside the fender under the trunk liner. I intended to mount the amp above the stock amplifier. Having a 500w amp powering a 300w sub is fine with me. Just tune it down, plus theres room for upgrading later. This amp ended up being PERFECT for my installation. Absolutely perfect. I cut two blocks of MDF scrap for a stand, spacing the Skar amp above the Audi amp. I am very happy with the size, the quality and the price... which includes a remote and a subsonic filter. Can't beat this one.

Superb Amp - At any Size and any Price

Really incredible how much power this amp puts out... and it does it efficiently! Takes my MB Quart Discus 10's to their absolute limits... very likely going to get some higher power subs down the line.
High quality terminals, quality crossover/subsonic, bass knob!
In such a small package, truly amazing. Easy to tuck this amp just about anywhere.
I've owned/worked with a long list of some of the great amps from many of the great manufacturers... this amp is right at the top of the list... THE top for the size and easily one of the best values in all audio equipment I have ever found.
Totally satisfied.

Great Amp

Gets down on my VD-8’s!

OK for the money

For what you are paying its a good value. The first one I got stopped producing output on the speaker terminals after 3 weeks. The RMA process is easy and fast and I received a refurbed amp within a week. For a sub $150 product getting a refurb (b-stock) replacement is expected. The big issue I have with this amp is that all the pots seem to be reversed. The gain pot goes from 0.2 to 8v and you would think that 8v is Max but that is not the case. The crossover pot also appeared to be reversed, if I didnt have an SMD CC-1 I would have been lost trying to set up the crossover correctly. Make sure you tune these amps with a sine wave tone generator, a multimeter, oscope, or an SMD DD1 and CC-1 to make sure you aren't clipping your signal.
Again for the price its a decent amp and it fits basically anywhere. Good value for the money. Skar, please consider changing the printed gain indicators to min-max to avoid confusion or at least ensure the pots attenuate in the proper direction. This was very confusing initially. I'm giving it 3 stars because the first one malfunctioned within 3 weeks of hooking it up, the replacement refurb had pots that were off center, and because the printed adjustment pot values are confusing and apparently reversed.
