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

Pleasantly surprised with this amp. This amp replaces my old 4 channel amp and mono sub amp. It is running my 6x9 front door speakers and 6.5 rear door speakers along with a 10” pioneer subwoofer. This amp is a bargain for what it’s capable of doing. The sound is nice and the build quality looks great. I would buy this amp again.

This Skar Audio SK-M4004D amp is a beast in a small package — delivers crisp, distortion-free sound and plenty of power for all four channels. It runs cool, fits anywhere, and really wakes up your speakers. Perfect mix of size, strength, and quality. 💪

Very impressed with the clarity and sound from a no name amplifier we’ll see how it holds up

The amplifier is in itself built well and performs as you can expect a budget friendly amp will. As per sound quality I installed this on my truck and it is quite comparable to the 600$ old kenwood that came out of it. It however does have some things to note that are important at this price point, the warranty is voided as soon as you install this thing, the internal components however good are still basic in nature, the installation process is slightly tedious with the output side clip but is expected, and the amp does get quite warm. Because the amp is basic in nature it lacks (at least in my experience) a line filter so that power from your alternator does not affect sound quality. You can simply buy a noise suppressor for the power feed to solve this issue. I did experience the fan never turning off and this was a problem as it does make an audible noise while on. I after already installing the unit and figuring this out, decided to break down the amp and disconnect the fan altogether. There is a simple clip you undo that is delicate but doable. THIS WILL VOID A WARRANTY. But it did solve my problem and after dynoing my 4 door speakers at full throttle for 20 minutes my amp did not get hot just the warmer side of things. After all the little fan didn't do much. I only did this because my amp is mounted by floating brackets under my passenger seat; if this was in a glove box or the trunk of a car there would be no problem. Other than the the sound quality is clean and powerful, the unit is built well and on the good side of heavy (not feeling cheap), and I can expect it to last. Update* the amplifier died after a few months of running it hard. However if you run it well within its ratings I believe it should hold up well

*EDIT 9/19/2018* --I have received a response from Skar support. Their answer was as follows: ""Thank you for reaching out to us concerning your SK-M4004D amplifier. Sadly, once you opened the unit to preform an inspection on it; you voided your warranty. However, not all hope is lost. Your unit can still be repaired at our authorized repair center."" --Out of the 6 screws on the back, none were marked as "warranty void if removed". Nothing I have ever worked on in the past (including laptops and other HIGHLY technical electronics) have ever voided the warranty just because the back plate is removed! Never in my life have I ever heard of such a thing. If Because I had volunteered the information about what I had done to investigate the issue, they are now stating that the warranty was voided. I didn't even touch the circuit board! Nowhere on the product OR on their website warranty procedures does it state that removing 6 screws to investigate behind the backplate will void a warranty. NO WHERE! Yet they want to tell me that I voided the warranty because of these screws that could have been rattled out (not even pasted/glued in, or even some weird hex head type!). --Thanks. Skar. You lost ALL business from myself and from my friends/family! --If I could give Skar a 0-star , I would, but suffice to say: STAY AWAY AND BUY SOMETHING ELSE/BETTER!!!!! THEY WILL NOT SUPPORT THEIR CLAIMS FOR WARRANTY!!! **original posting** --I'm not sure on if I would ever recommend this product. One coil is completely broken out while another coil is hanging on by one end. --I took off the backplate when I heard the rattling around inside in order to investigate what was going wrong. --Notice my internal photos and compare them to the stock photos on Amazon listing: In my photo, the amount of glue that holds the coils isn't anywhere near as it is in the stock Amazon photo. Odd, right? Skimping on glue to save a buck. Bad Skar, no cookie. --I have contact Skar to find out about a repair/replace, but I am not expecting much from the company. Supposedly, Skar covers their products for 2 years, but I have a feeling that they are going to pull the "Amazon isn't a branded/licensed/reputable/overpriced dealer, so we won't cover!" --Funny thing is, no other hardware that I have on my vehicle has ever fallen apart like this, especially in such a short timeframe. --Do I expect them to respond? No. --Do I expect a response that actually is beneficial to me? No. --Why do I not expect these things? Because I have had too many bad experiences with manufacturers in the past and I'm still a bit jaded over them. --Would it be nice if something were to come about that would be beneficial to the customer? Heck yeah! But not expecting it. --I'll keep this updated if Skar can come through with a decent reply (if any at all).

This was as described, and would no doubt work OK but I found after receiving it I really needed 6 channel s for my OEM sound setup to replace the factory amp. Return was handled properly.

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 system this amp pushes four 6.5 midrange speakers and one 10 inch sealed box sub very well

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

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

Good value, lots of power. make sure you mount this amp with a gap as the fan is located on the bottom. It worked a lot better for me once I gave it more room to breathe. It gets hot and will overheat if you do not do this

Sounds quality good power and ground screws sets backoff causing powerless only thing haven't tried is lock locktite in theads to prevent blackout of set screw

Have 0 issues so far, no overheating problems and powering everything very clearly

I purchased the SKAR Audio SK-M9005D amplifier six months ago with high hopes for its performance, but unfortunately, my experience has been less than satisfactory. The amplifier, which I had expected to be a reliable investment, unexpectedly failed after only six months of use. Initially, I was impressed with its features and seemingly adequate performance, but the premature failure has left me extremely disappointed. What's even more frustrating and disappointing is SKAR Audio's refusal to honor the manufacturer warranty for products purchased through Amazon. Upon discovering the issue, I promptly contacted SKAR Audio customer support in hopes of finding a resolution. To my dismay, I was informed that the warranty is not valid for products purchased through Amazon, leaving me with a malfunctioning amplifier and no recourse for a remedy. Please note that Amazon is also refusing any warranty, replacement, or refund for the broken amp. This lack of warranty coverage for Amazon purchases is a major oversight and has significantly impacted my perception of SKAR Audio's commitment to customer satisfaction. A company's responsibility should extend to all customers, regardless of the purchase platform. While I initially had high hopes for SKAR Audio, this experience has left me hesitant to consider future purchases from this brand. In fact, I consider the quality of their products inferior and will never be supporting this brand again. I hope SKAR Audio reevaluates its warranty policies to ensure that all customers receive the support they deserve, regardless of where the product was purchased. Hopefully no one else has to experience the utter disappointment and frustration Skar Audio has caused me.
