MB Quart FA1-1500.1 Mono Channel Car Audio Amplifier (Black) - Class SQ Amp, 1500-Watt, 1 Ohm Stable, Variable Electronic Crossover, LED System Protection, Heavy Duty Connections, Bass Remote Included

Bought this as a replacement for an old HiFonics BRUTUS that I had for over 8 years. I was honestly shocked at the output. It made my kicker 12 so much louder I had to turn the gains down on the head unit. I gains matched my system prior to connecting, so it was a real shocker when I connected it to the sub lol.100% if needed would buy it again.

Worked fine. Especially for price point!Read thru the competitive marketing on all electronics.1500 watts at 1 ohm rating =750 watt rating at 2 ohms=375 watts at 4 ohm ratingMost subwoofer are 4 ohm rated meaning this is 375 watt unit.I don't believe it shows at what distortion on spec sheet. Further muddying the ratings water of all electronics rates for comparing. Just the way Marketing is. No deception by MBQuartz

Install was a breeze since it was a replacement and adjusting it was well a bit different from the old style,less things to turn and way easier in my opinion.. power wise it seems to pull its weight but then I'm only pushing a 8" NVX 650w wired at 1ohm sub and it does the job with power for a couple more which I'm working on.. I did run a power test and at 1ohm it did hit @ 1800 avg watts 2ohm was @ 1000w and 4ohm I got 600 watts so go with as low of ohm speaker you can for peak power.. oh the top lights up and looks pretty cool too and comes with a no frills bass knob.. its worth it i guess

I had it running at 1 ohm connected to a 500watt RMS sub. The sub still works the amp doesn't. The gain was way lower than it would be at for a 1500w RMS sub. Don't buy it for long term use at 1 ohm or the RMS claims. It has a fuse limit of 80 amps. Optimal car voltage is 14.4volts while running. And give it a generous estimate of 80% efficiency at 1ohm would see this thing at around 900 to 925 watts RMS not 1500. I knew this going in, I just expected to last longer with the lighter load.

works great

Excellent mono amplifier. Size matches the 400 watt 4 channel perfect. Using it at 2 ohms to run 2 audiopipe txx subwoofers. It handles them with ease but does consume the power. The built in low pass filter and subsonic filter are good but not great, the auto on feature works as it should when voltage is detected however you have to have a moderate level going in or it won't work. So using a phone, listening to anything at low levels, or listening to anything with pauses like audio books is out of the question with this feature. This is a good amplifier for the money and as long as it isn't a used should last a long time.

So far so good. Fast shipping from seller. I have a 12 inch kappa subwoofer connected to it, its set at 2 ohms and yes it feels like its pumping out 750 watts. Worth the price per the output. I have never used this brand so we shall see how long it last.

I bought this amp for my mids and highs in my truck. I was trying to stay around $500 for the entire system. This amp is powering 4 6X8 2 way MB Quart speakers above 120 Hertz. The sound is absolutely amazing. If you're looking for sound quality, look no further.
