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.

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.

I have this amp powering Kicker Ks series, front doors 6x9, dash 3.5 wired in parallel, rear doors 6.5’s and this amp sends good power and sounds great in my 2022 Toyota Highlander, I do have a sub but take it out from time to time for traveling and when doing so still wanted a good sound, good was achieved

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.

Purchased this a few months ago. Installed on 4 3-way name brand speakers that have been in my truck for a few years. Had the levels professionally set. It was the cleanest sounding amp I have owned. I could turn it wide open and it sounded great. Until this morning...got in truck to go to work and popped in the remastered cd of Megadeth Holy Wars and 2 minutes in the amp cut out and sounded like frying bacon coming thru the speakers. I immediately turned it off. Waited several minutes and turned back on. And with only 2/3 volume it cut out again. So, I don't know if the remastered copy of this cd pushed the amp too hard or if this amp is just a turd. I've owned alot of amps thru the years and never even had them professionally dialed in but I never had this problem.

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.

La calidad es buena por el precio, aunque al ser de clase ab consume más de lo que entrega, alimenta 2 6x9 pioneer de 100 whats rms, 2 6.5 y 2 twiters, es bastante bueno, pero se calienta mucho.
