    Those focals aren't that great for the price and if you are going with sq speakers i would suggest a better amp than mb quart. Quart is great on a budget, but not so much for sq setups.

    I saw in a video that amplifier is not stable to 2 ohm , but in their specifications say it is.
    I know several forum members already have the amplifier or other amplifier MB Quart brand and wanted to share their experiences.
    addition and how could yo do the installation?

    Mb quart is ok for cheap power, I run a older one for now, but I will be changing that. Depends on what you want I guess. Judging by the fact that you said focals I am assuming that you are going more for sq, but you don't run that many speakers for a sq setup. Also on the focals much better speakers can be had for the money.

    your Amp is fine. In that video the seleniums are the biggest factor in that setup. Imo your installation plays the biggest factor in your final outcome. People say most amps sound 99% the same, its the last 1% that makes the difference. Tweaking your setup imo makes a bigger difference than your amp. Meaning as long as it produces a clean signal, and does rated power, you really won't notice a difference.

    If you already have the amp and speakers, provided the install is correct, you have a pretty nice semi-budget setup. that amp will be fine at 2 ohms though. What's your budget on a sub?

    125rms per channel at 4 ohms is no joke, thats a ton of power.

    And what makes the Onyx not so great for SQ set ups? because it isnt expensive? Its not a Zed or Phoenix Gold? funny you say this when you yourself are running a 2150 that was the forum budget boner amp 2-3 years ago.

    I have owned several of those discus amplifiers and I like them, The Onyx is no less of an SQ amplifier then the discus or any other amplifier. I run the Autotek line that shares the same internals of those Onyx amplifier in a Competition SQ set up and take home trophies. I have beat out guys running Mac, Zapco, Hertz and other high end amplifiers/speakers, Its all about placement, Stage and install and image. This year I added another autotek 4 channel and a set of 4" speakers and bumped myself up a class.

    Op your amplifier is going to work out just fine with your front stage as long as you cross those things off at the right cut off and have good placement, you made a good purchase. this will sound nice for a daily set up.

    As you and I stated they are ok on a budget, but the signal they produce is not that clean. The Onyx is supposed to replace the discuss series, but it is even cheaper built than the discuss. I bought my discuss when I had no money and it's been good for it's purpose. I am upgrading to a better quality amp though that will put out clean power. The internals on the quarts are cheap components with loose tolerances. Regardless I will recommend them to people on a budget, but for someone looking for good sq I would look elsewhere.

    Re: MB Quart ONX4.125 1000W RMS question? please

    MB quarts aren't what they used to be. Ever since maxxsonics got their hands on em. Nonetheless decent budget amps, and with the correct install, can be made to work for a decent SQ setup. While install, placement, aiming, crossover points, etc will play the biggest part in a SQ build, you won't see too many of the new quarts in the higher class sq lanes. For daily driving, it just depends on personal preference. Personally, I dont touch the maxxsonics amps. But alot of people love em. Depending on the OPs budget, he may or may not be able to get better for his money. But I dont think he can go wrong with the quart, especially with that much headroom.
    But to say the quart will keep up with any amp for SQ is a little much IMO.

    I was looking at the MB amp as well. After reading this Ill look elsewhere.

    You guys all say its not good for SQ but haven't recommended anything else...whats a good budget SQ 4 channel? Lets be reasonable for price...150.00 to 300.00
