Great buy, puts out over 1500 watts at 1 ohm. Stays cool even after running for a long time at high power

Great little amp. Super powerful for such a small amp. Although it claims it can push 1 ohm. I wouldn't. I'm not sure I would push 2 ohms with it either. At 4 ohms, its warm to the touch. But for 4 ohms, 300 watts rms, I think it's probably the best value you're going to find. Stinger is made by audio control. Pretty good company from what I've read.

I got the STINGER MT-1500.1 to power two 12" subs in my Ram 2500, where space is super tight under the rear seat. This amp’s compact size was a lifesaver—it fits perfectly without sacrificing any room. Despite its small footprint, it delivers insane power, driving my subs with deep, clean bass that rattles the cab without distortion, even when I crank it up. Installation was easy, and it runs cool during long drives. For the price, this amp is a steal and ideal for anyone needing big sound in a small package. Highly recommend for truck setups like mine!

POS didn't last 6 months before randomly going into Protect mode, didn't even happen while using it, just randomly got in my car and noticed my sub was off. Tried EVERYTHING, rechecked ground, disconnected every single cable from the amp beside power and it still shows protect. I run a 150 watt , low profile, mini 8 inch sub. Absolute trash product. Im beyond pissed since I have gotten cheap walmart amps in the past that worked beautifully but thought I would go premium this time and spend extra on the Stinger so I can upgrade down the line. unbelievable. again it shows protect with absolutely no cables attached to the amp, and this is a known tested setup, power and ground in the exact spot as my last amp and sub, all cables the same, lowest gauge everything. just garbage.

Hooked to a single Fosgate T1 10, at 1ohm, and it hits incredibly hard. I was very surprised by the quality and power of this little amp

Definitely woke up a kicker 10 comp r up that a 800w skar couldn’t do. Definitely gave me the sound I wanted from the subwoofer. Very budget friendly amp that put a quality sound and power out. I wouldn’t hesitate to purchase another one if I needed it.
