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 A/B 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.

This was my first 5 channel amp and I was pleasantly surprised at how well it did the job. It looks fantastic and delivered all the power I required to the rest of the system flawlessly. Tuning was simple and the standard operating temp was unbelievably chilled, it was below every other amp I've owned before.

Currently have this installed with 2 pairs of MB Quart 6 x8 components and 2 Boston Acoustic 10.5lf Pro subs. The front and rear channels have a lot of power and overall the amp has a lot of features.
However, the 5th channel lacks a bit, however acceptable for my listening levels. I have the 2 Ohm 10.5s in parallel so I'm presenting the amp with 1 Ohm. That was one of the reasons I bought this amp as it was 1 Ohm stable. The 10.5s just require a lot of power to get them to stand out, previously I had them paired with 1000watts at 1 Ohm and that was a good match.
I would have to say though now that I'm older, this is a perfect one amp solution for someone looking to have a single amp driving everything. Has a load of crossover and tuning options, the bass control works great as well. Just don't expect it to drive monster sub woofer loads. Would I buy again for a standard car audio system with great sound quality, yes! Would I buy it for a competition system or at least one over the top, no.

I was looking for a good SQ type amp for my pickup (limited space) and found this was 1 ohm stable on the sub channel for future upgrading.
The filters make it easy to keep bass out of the speakers that can't handle it without use of the head unit filters. Sub is crisp and clean but not insane. For the price I was very surprised how clean an amp this is, just don't expect to win any SPL awards. Perfect for listening to your music instead of using it as a back massager :)
The only weird thing is that there is no external fuse on the amp, and they suggest a 120 between the battery and the amp. I've run a 60 amp since ownership and haven't blown it yet. I suspect you would need a lot of load to warrant a 120 amp breaker/fuse.
I would buy again for this application, but would always run different amps for sub and components given the space and budget.

Bought this around 6 months ago for my whole system, running a Fi Audio 10" sub and 4 5.25" JL Audio door speakers. This thing sounds really clean and doesnt seem to draw too much power. The door speakers sound so much better than when using the deck, you almost dont need a sub.
i have my sub running at 4 ohms, so i could be getting more power out of the amp, but it still slams really hard. I also noticed that i dont have engine noise anymore, probably because of less draw on the alternator.
Build quality is pretty good overall, my only annoyance is that the tuning knobs are kind of set-in to the amp frame so you need a screwdriver to get to them. Just makes it harder to tune it tight spaces.
overall i am really satisfied with this amp, would buy again.
