Success is a Measurement of Quality and Power

The success of any car audio amplifier depends on system quality and construction, ease of installation and configuration, and sound enhancing features. MB Quart engineers built the all new Onyx series amplifiers from the ground up to be an affordable amplifier with the audiophile and performance enthusiast in mind. This series is composed of value-packed class-D and A/B class amplifiers that boast affordability without sacrifice to power or quality. All Onyx Amplifiers come clothed in a beautiful new age piano black finish which accents interiors and brings a whole new level of sophistication to swallow. To match, the line of Onyx Speakers shows off the same piano black finish applied to their polypropylene cone woofers. It’s a perfect match every time.

Speaking of features, Onyx amplifiers bring the full tuning spectrum to your fingertips with variable high-pass, low-pass and subsonic filters built-in. To increase endurance, MB Quart designed Onyx amplifiers with military grade printed circuit boards and built-in system diagnostics that keep these amps running strong. High speed MOSFET output devices are used in the power supply to give you the best watts-per-dollar ratio. It’s not hard to see how success has been written all over these amplifiers, though with a piano finish that looks that good, we know you will be staring.

I was in the market for an amp to push a Sundown Audio SA-12 dual 4ohm I picked up, with the ability to ideally push two of them when I got another one. Based on the reviews of the SA-12 it sounded like pushing more than the 600rms was going to be completely okay, so I was looking for 600+rms @ 2 ohm for initially hooking one up, and then 1200+rms @ 1ohm for when I picked up another sub. I wanted to cop the Sundown 1500d but it costs buku. Currently just have this pushing one @ 2ohm and this combo hits almost as hard as the 2 JL-w6 12s on a JL 1000.1 slash v1 I had. Nice and clean also. Originally I had planned on running the 2 SA-12s off the one amp but this one is taking the 1000w so good that it seems silly to drop it down to 750w a piece. Blasting it in traffic today for about two hours total its running barely warmer than it was in the car. Nice and cool. Woulda been nice if the 12v and ground terminals were a bit bigger so you could get the 2ga cables in there a bit easier but they fit.

Low points on Look/Design because the whack orange/red light up logo. Would have preferred it blue or color neutral with no light and instead just being a classy piano gloss black amp. Then maybe it would have gotten mounted where it was visible so someone could want to rip me off. So maybe that's really a plus/minus?

Four stars on durability simply because the back/bottom board where the "warranty void if removed" stickers are seems kinda loose/cheap. Doubt this will ever be an issue whatsoever, but this amp is not a tank.

Overall, a great amp for the money. Really happy with this amp, very likely will buy another when I pick up another sub.

I bougt two of the these mb quart 1500 and I'm really trying to knock my trunk off, with my 4 JL w3 13s. I know they are not massing out the subs but they make the competition step it up a notch. I ideally wanted to put 6 of the rocksford fosgate R2 12 in my trunk they rms 250 a piece. All in all I love the amps. Don't get me wrong they are not JL, Rockford Fosgate, or Kicker but its worth the money believe that.

This amp is a must buy. I'm running a kicker cvx 1000rms on this amp and this amp keeps cool no matter what comes at it. To add to that I find its not dimming my amps compare to the other amps i have purchase for bass.

I have this amp powering a Rockford Fosgate T2 15" and it sounds clean and loud. Makes my t2 hot I play loud max good efficient but I need an extra battery because stock batt not enought to maximize this amp. You need use 0 gauge wire lot difference sound quality only problem is d terminal is tight to 0 gauge wire. I also use this amp to power the mtx rfl 15 2000 rms and I blew the sub.
