    • Impressed - Performs well
I am using this on a 9 speaker system for a man cave powering it with a 50A 12v power supply. Speakers are inexpensive 8” Pyle 50w RMS 250w peak ceiling speakers . They are wired so that 6.5 ohms is the impedance at the amp. I personally would never run 2 ohms or less on any amp, despite it’s claim to support it. I prefer 6 to 8 ohms. Amp will run nice and cool and will last forever. If not loud enough, I get a bigger amp! I don’t overdrive the MOSFETS by dropping the load impedance. I chose this one for the low and high pass filters built in. They work very well. I have two channels feeding 8 mid/high speakers, and the other two bridged to run a 12 in sub (dual coil wired for 8 ohms). At 50% gain it gets plenty loud, sounds real clean and barely gets warm. Totally rocks the man cave. I am pleased with it so far. ... show more

    • Amazing sound quality
Pretty compact little amp so it's easy to mount . It's a class A/B amp so sound quality is outstanding, but you get a little more heat with this kind of topology. Overall the build quality and sound quality are both equally amazing

    • Only good for frying eggs!🍳
I’ve done quite a few car audio installs in my life, so I understand how to match specs like wattage and ohms. I’ve matched this amp perfectly with the true RMS wattage values. No bridging channels or anything actually complicated, just four channels at 4 ohms, 80 watts RMS per channel on full pass, gains less than half w/no clipping. During the setting of gains and crossovers I noticed that it was getting hot but I didn’t run it for more than a couple of songs straight. So I guess to make a long story short, this amp overheated the first time it was at a decent enjoyable volume for a half an hour. I then switched it to high pass frequency thinking it would put a lot less strain on it, but the same results. This amp is a huge disappointment. Only good for frying eggs! ... show more

    • Great Overall Sound and Powerful Little Amp
Review Image by Spencer Ohe Spencer Ohe
Review Image by Spencer Ohe Spencer Ohe
Overall I really like this amp. I bought it because it was one of the only four Channel amps with a decent RMS power rating and small form factor. However after installing it, my main complaint is how flimsy and crappy the high level input wires are! I mean there are literally like five or six strands of copper and very delicate to work with. Plus they are made of computer ribbon cable and the wire markings are all completely different so you have to go by what the plug lines up to you with the pins on the amp and take your time wiring it. The gain seems to be really sensitive and I am only running mine about a quarter of the way up. Oh and the second main complaint is that yes this is Amp does get HOT! I have mine mounted under the passenger seat with another subwoofer amp, but I get constant air flow from the under seat air vents. I'm living in Arizona so my AC is always on in the car anyhow and keeps the amps that a reasonable temperature. All in all I don't regret the purchase, but only time will tell to see how it holds up. ... show more

    • Excellent amp when you have limited space
Review Image by Bn3888 Bn3888
The Amp powers 4 infinity speakers in a 2 door 04 Silverado Limited space and mounted on top of the sub box fits perfectly. Also put sub amp on the bass box and its a perfect fit. This amp replaced a Kenwood same wattage and This amp blows the Kenwood away. I was impressed day one and still impressed today. ... show more

    • Runs Hot on 2 Ohm load....
This is a heavy little amp and I do like the sound, however it runs hot on a 2 ohm load. I hooked it up just on the front channel to a set of 2 Ohm 6.5 Infinity Kappa components and after 30 minutes of playing at just above mid volume, the amp was very hot. If I continue using it, it will most likely overheat, which is a shame. It actually sounds pretty good My guess is on a 4 Ohm load it would do well. ... show more

    • Good AMP
Running 2 D&D 10 inch subs. Custom box pushing them pretty good. Can easily blow them, I really don't want to recone my subs.
