Features

  • CLASS Q1 AMPLIFIER - MB Quart's Class Q1 offers the efficiency of today's D-Class with increased engineering to focus on sound quality from the power supply through the output devices (FLUID-FETS). Mono only operation mode.
  • COMPLETE SOUND CONTROL - Variable electronic crossovers allow for complete control of amplifier output with on-board electronic crossover to tailor specific frequencies to speakers and subwoofers. Check specs for specific frequencies for this amp.
  • HI LEVEL INPUTS - The DC Signal Sense switch allows the amp to turn on when a signal is received on the RCA inputs, so an amplifier remote turn on wire is not needed to turn on the amplifier (this feature can be turned off).
  • HEAVY DUTY CONNECTIONS - High quality connections allow for secure electrical signal to pass into wiring and resist erosion which will add longevity to the amplifier. Secure connection is made for all power, ground and speaker connections.
  • POWERFUL - Output devices are selected for their ability to efficiently produce power and mimic the sound quality of the highest end home amplifiers. MOSFET power supply allows amp to produce efficient power without taxing the electrical system.

    • great output, clean sound, best price.
Model: 2000 Watt Monoblock
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. ... show more

    • Good Value for money/ Sort of a name brand
Model: 1500 Watt Monoblock
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 rating Most 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 ... show more

    • Easy set up
Model: 2000 Watt Monoblock
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 ... show more

    • its been less than a year and the amp died.
Model: 1500 Watt Monoblock
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. ... show more

    • Excellent mono amplifier
Model: 2000 Watt Monoblock
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. ... show more

    • Works as described
Model: 1500 Watt Monoblock
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.

    • Awesome sound quality.
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.
