Audio MT-600.4 Compact Digital Class D 4-Channel 1000W RMS Car Audio Amplifier with Bass Knob Remote Control, HEXFET MOSFET, High/Low Pass Filter & Crossover Multiplier

Great value for the money. The build quality is good. The sound is clean at it's rated output (which it exceeds). Its small size makes installation choices easy. It really doesn't get hot so heat is not an issue. The features function well and are clearly labeled. Advice: run quality (not CCA) power wires and at least a 60 amp fuse as these amps are power hungry!

The absolute best bang for your buck amplifier money can buy. Period. This entire line of Stinger amps are a gift from god of clean power and affordability. Mine makes zero audible noise at ridiculous volume levels. These are some of the most slept on underrated gems in car audio, period. I’m telling you, I upgraded from a Taramps TS800 and let me be the first to say, there was a huge night and day difference in dynamics, clarity, soundstage, noise floor, and I’m so happy I spent a little bit more on this amp to get the next level in performance. You’d have to spend so much more money to get any better at all, and I doubt you could notice a difference at 10 times the price. Especially in the sub amp, but maybe in the 4 or 5-channel. I have the MT600.4 on front stage and MT1500 pushing one 15 and one 12 in separate ported enclosures in a 2024 Kia Niro and it absolutely slaps and it plays loud and clean. You will not regret saving your money in this economy and going with these rock solid amps. I know I’m so happy I did!

Holy Chit. Got a 2010 Titan and it had kicker everything (except the subs which were being run off a 14 year old no name 4 channel amp. ) Got a Skar amp to replace that and was FULLY impressed. Now all my mid bass went into the toilet. Was thinking about getting some Hertz Centos for the door and the Kicker 4 channel 65w unit went into protection mode. Long story short, I had success with the Monoblock running my 2-12" kickers down to one ohm. And they had same-day delivery on this nice little 4-channel amp. Hello MIDBASS. Wow...woke up those Kickers in the doors rather nicely. Not as crystal clear as the Centos will be when I get them, but a LOT better. (I do have the Hertz Deici tweets in place of the Kickers....in your face with a huge sound field....now only just a tiny hole in the midrange. Some eq tuning might bring back that little bit. So simple answer is, your vehicle is not a listening room. You have base noise your never going to overcome. Manage maybe, but overcome....never. This company is producing probably the best bang for the buck amps I have ever heard. Do not think twice...just get it and enjoy. Highly Reccomended.

This is a great amp. I paired it with the 2000.1 mono block and the two of them together just crank. My only complaint is the clipping light is lazy. I had audible distortion in my system before the light turned on. Confirmed it with a scope. It's certainly possible it's just my amp but it did it on both front and rear channels so I personally wouldn't trust it. Buy yourself one of those 30 dollar pocket oscilliscops and make setting the gains on ANYTHING easy mode. Once I got my gains dialed in this thing sounds fantastic. Plays very cleanly and has the power to drive pretty much any mid/highs set you can throw at it. I'd buy it again in a second.

I bought this amp to run my door speakers and my goodness what a mess this amp is . It created so much distortion that I just turned my system off I'm running a skar 18 the zvf and the noise was louder than my bass so I un hooked my entire system hooked my old Blaupunkt amp back up and lo and behold no noise . I wasn't ready to give up on the amp so I though it could be my wiring job so I went to my expidition I'm runing 2 svr 10s and 2 12 svr all skar I hooked it up to the door speakers in that one and the same noise jump out of it immediately just for your information I changed every rca cable rewired the whole system in there re did the ground the whole 9 and the noise persisted so I hooked the old Blaupunkt amp back up as well in the expidition 2010 and my other vehicle is a 2001 ford f250 really want my money back or a replacement really want a replacement I like the build but the quality just isn't there on this unit now i have to buy another amp which is ridiculous

I now own the Stinger MT-600.4, MT-1000.1 and MT-2000.1. I tried the MT-2000.1 first to power 4 Rockford Fosgate P3D4-10... Rattles everything! So, class D is fine for subs, but didn't know how it would do with door speakers. The price point is so good on the Stinger MT-600.4, thought I could at least try it. Received it, installed it and WOW! I cannot hear a difference between the Rockford T1000 and the Stinger MT-600.4. The power, clarity, size, and price is beyond my expectations. It is running the 4 door speakers which consist of pioneer TS-M650Pro 6.5 and pioneer TS-A879 3.5 coax. Since both are 4 ohm wired in parallel I'm putting a 2 ohm load on each channel of the amp. It handles it with no problem and it is too loud to turn to max volume, and crystal clear. All of my Stinger amps perform flawlessly. They run super cool too. Absolutely the best purchase.

I have waited to review so that I could install, then play the amp for a while. It's a solid performer with an easy setup, strait forward labeling and function. The unit can fit well under a seat. I am pleased with the output and sound.

When I receive this app, I was a little hesitant and I was like this thing is so tiny. It’s about the size of a carton of cigarettes, but man are my speakers screaming in the truck right now. had issues with engine whining noise stepped up to a four gauge ground. Don’t seem to be having any problems now. Highly recommend this is replacing an alpine amp from over 20 years ago.
