Skar Audio SK-M9005D Compact Full-Range Class D 5 Channel Car Amplifier, 900W

As someone who has been into car audio for several decades I was very skeptical that this amp would perform for this low of a price. I read reviews and watched YouTube vids of amp dynos and this amp is legit. It puts out more power and sound than my alpine amp I replaced with it and for a fraction of the cost. It’s definitely worth the money and it performs very well. I haven’t had any problems with it so far and it hasn’t shut down from heat or anything either. I’m pretty impressed and I think you will be too. I’m definitely recommending it and if you’re on the fence about it, go for it.

OK. Normally I will not write a review, even if the product is horrible. When I first opened the package, I checked several labels to make sure this is what I ordered. (It was much smaller than expected). I installed the amp hoping it could at least push the four 6.5 speakers that I installed in the doors of my rogue. It sounded horrible, but I was jumping to conclusion because of the size of the amp. I didn't even adjust the gain or high pass setting. After a few adjustments the mid/hi range speakers were very good.. the amp felt hot to the touch though. I figured that i would have to buy another amp for the 10 inch sub. I decided to connect the sub just for reference..This small amp that carries 8 gauge power/ground and 14 gauge output speaker wire is very impressive.I have no need for another amp. (it did not over heat) Note I'm not in competition phase. I just wanted an inexpensive and simple 5 channel system, to improve the factory systemthis amp pushes four 6.5 midrange speakers and one 10 inch sealed box sub very well

It’s a good amp don’t think because of 4 stars that it’s not. The only thing I’m not a fan of is the 8ga power & ground. I ended up buying 6ga and it’s a tight fit but works. I ran 4ga back to my second battery and 6ga to the amp. It puts out the power I needed. I was going more sq with this build. I didn’t need 2000+ watts for the build. I’m getting around 70 to my mids and 450-500 to my sub and I’m happy. If you need clean power in a small package this is worth a look. I looked at the JBL that was in the $300 range and this worked just as good and smaller.

So the sound is good....when the amp isn't in protection mode.I had 4 6x9s and a Street Edge Memphis 10 inch sub. The amp would work for 20 minutes max then go into protection mode for like 10 seconds. It overheats like crazy. I tried to take off most of the load by putting the sub on a separate amp but it still overheated. I had to replace it and just go with 2 amps. Now I'm running 2 1000 watt amps and neither of them get even close to how hot this Skar amp gets. I understand that it's cheap therefore quality won't be 10/10 but it's useless if it doesn't work. This amp gave me nothing but stress and a hole in my pocket. Just do it right the first time, don't be cheap like me.

Didn't want to deal with power distribution to multiple amps, and didnt want to run 0/1 guage for higher wattage amps that don't put out the power they say. Ha e this amp running 6x9 Alpine R components, 6.5 Alpine R, and a 10in solo L5 on 4 guage wiring. This thing pushes the entire system HARD! Sounds amazing! If youre a minimalist on a budget and looking for a single amp that will run an entire system, I dont think you'll find any better than this.***NOTE*** One thing I DONT like..... all 5 channel connections are done through a single plastic 12 pin connector into the amp. I'm sure it's fine as the wire is heavy enough, but it means you will have to make wiring connections(butt connectors or solder). I don't plan on changing anything any time soon, so I'm fine with it I guess.

I installed in my boat and have 4 channels wired to the cabin speakers and 2 subs to the single channel at two ohm load. Sound quality isn't bad for a cheap amp and it definitely has it's rated power. My speakers are LOUD. I'm hard on stereo equipment in boats so we'll see how it does in the long term.

Edit: I bought this in January 2021 and it is now October 2022. Amp has stopped working. Power and inputs has all been verified with oscilloscope, all the speakers are still good. Amp just keeps power cycling. It was a great amp that gave me no problems. It just would not turn on one day, no other signs of issues before that point. If these were still in stock, I would probably buy another one, just because this amp matched my power needs exactly.I have a small car, so space was a was a major concern when I picked out my amplifier and speaker package.I chose this amp because it had the power I needed in a small size. After an hour or so at full volume it does get slightly warm, but as long as you have good power going to it, it should not get hot. I ran 4gauge all the way back, then dropped it down to 8 gauge for the last 14". 4gauge wire is not necessary, but it doesn't hurt anything either.I am using this to push 4x Hifonics ZS65C Zeus 6.5" 4ohm component speakers and a single 2ohm Kicker 10" CompRT (one powered subwoofer, one passive subwoofer in a compact box)Pros:- Very powerful for the size- Great sound with no distortion- Stays cool- So small it will fit almost anywhere- PriceCons:None of these are a deal breaker, I am putting these here for people so they know what to expect.- The remote bass control knob uses a headphone style jack instead of the usual RJ-45. I'm sure they did this due to available space.- All of the speaker outputs are on a small plug instead of screw terminals. This makes for a slightly more difficult time trying to make everything look decent on install. Again, they probably did this due to the small size of the amp.- The connection for the remote turn on wire is way bigger than it needs to be. It can fit around a 10 gauge wire. 14 gauge wire just looks odd in the connection.None of the cons would stop me from purchasing this amp again.I would highly recommend this amp to anyone looking to power their whole system.
