Good bang for your buck. Does great for my purposes. Runs a 8" kicker comp r sub.

I bought this mono-amp to pair with a 12 inch Comp-R Kicker single sub. Its amazing so far. Ive had no issues, and the RMS rating was certified tested at 498 RMS, well-above the 400 rating on the box. I absokutely recommend this if you’re on a budget/pushing a single sub.

I would be hard pressed not to increaes the rating to 4. I still say if you pay more, you get more... but than thats true for all things in life. So in a nutshell.

Perfect with my 12” down force kicker set up being I have a double stroller in my trunk along with it.

Made my stock speakers sound 10x better and it works well with my sub.

Nice amp!!!works great!!!!!the easy-to-use was pretty good!!

Have the amp in my Supra. Had it for a couple of months now and it hits hard and has never failed on me.

I'm thrilled with my purchase of the KICKER CX 400W Class D Digital Mono Amplifier. Its power and clarity have seriously upgraded my car's audio system. The compact size is perfect for my setup, and the build quality is impressive. It delivers clean, powerful bass that has transformed my listening experience. Definitely a great choice for any audio enthusiast looking for a reliable and high-performing amplifier.

Lots of power and great sound small piece would recommend to anyone

Lets see ive had this for about a week now, decided to stop being frugal with the amp and upgrade after my original sub was stolen and ill admit i was totally on the fence about upgrading to this specific amp for the price the 400rms seems low but its exactly what i needed to match with my replacement sub the: 44TCWC104 so ill start with cons.. if you have 4 gauge or bigger you wont be able to use this amp unless you're willing to purchase an adapter to allow the thick red and black cables to slide in and fit youll need something like this:SCOSCHE X2BS4-4 4-Gauge Spade Terminals 4-Pack and im nkt kidding good luck finding a better way and better luck finding one not on Amazon trust me i checked wallmart and auto zone those donot fit. The last con would be for the price the could have included a bass remote but thats not really a bid deal pros would be provides noticable clean punch immediately while almosg taking uo no space. Also the certificate that comes with it says mine specifically is 498 rms not the before mention 400 rms which i dont have any issue with. All in all a very solid purchase i would recommend to anyone looking to power something around 400 rms.

I have this amp paired with a 10" Kicker CompRT DVC Shallow mount sub. It sounds awesome! The amp has a small footprint, so its easy to find a spot to mount it. That's important to me because I have a Subaru BRZ (small car) and space is at a premium. I have it mounted beneath the carpet in the corner of my trunk. So far I haven't had any problems with heat in its current location. I love that the amp has the ability to be 1-Ohm stable. It provides a ton of sub wiring options to get the most power from the amp. Options for speaker level input or RCA input and small (8AWG) power /ground wire requirements make this amp easy to install. I have a Bass Boost knob added to mine as well for the ability to tune on-the-fly. At $150.00 you will get a quality amp with many capabilities delivering clean sound. For the price and performance, its very hard to beat this amp! I definitely recommend!

I’m so impressed with how small but powerful amps like these are now a days. For the price alone it’s a great value! Plenty of head room and bottom end from this amp. I run two 8” sub enclosures with it in a loud noisey Jeep and it provides plenty of bottom end for me.

I paired this amp with a 10" Kicker CompRT (43CWRT102) and it is an excellent combination. Kicker amps have always been known to produce more watts than they are advertised to, and mine is no different. The certification sheet that came with the amp states that my unit produces 477 watts @ 1 ohm. Kicker's introduction of 1 ohm stability allows me to power the sub with all 477 watts this little amp produces. Can't recommend this amp enough. It's a minuscule powerhouse and an absolute unit.

Produced solid sounds, surprised at how much punch this thing put out in my sedan. Love the convenient controls and hookups, and nice compact size!

This amp is very nice it blew my expectations and went above and beyond with it’s performance would 10/10 recomend this to anyone looking for a compact amp with big sound!

This amp fit right under the driver seat where I had my last amp. Easy to install and sure drives my 12 inch woofer! I am pleasantly satisfied and impressed! Would definatly recommend and also with the price tag it's a no brainer!

Great product, easy to set up and well built and powerful

Great amp for the money and it doesn’t take up much space.

Lots of power in a small package. Got a great deal on sale + a Kicker promotion. Also had it installed by BestBuy. Currently only have 1 10" CompC sub running off it, but I know it can handle more.
