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.

I was really wanting to get the MB Quart REF 4.80 to drive my mids and highs, as I already have the MB Quart REF 1.800 driving my subs. Unfortunately, that amp has been discontinued. In my search, I ended up calling MB Quart directly to try and get this amp, as it was no longer offered for sale by Sonic. In speaking with them, they told me try one of their Authorized Online Retailers, and Sonic was first on their list. I mentioned to the CSR that I already tried Sonic and it was unavailable. I then called MB Quart up again, and they reccomended the ONYX 4.60 to meet my needs. My main concern was having a quality amplifier which was also CEA 2006 compliant. Sonic had this amplifier in stock, and with their Low Price garuantee, I was able to pick this great amp up for a great price. How great is that! I currently have this amplifier driving 2 sets of the MB Quart ONYX OTK-30 Widesphere Tweeters and 2 sets of the Rockford Fostgate Power Series T-1682 6 x 8 coaxials, all of which I picked up from Sonic at a great price also. Totally Awesome are the only words that I can come up with for this amp's perfomance on this set up, it really made my mids and highs come to life. It also relieved stress off my head unit's pre-amp to deliver a more full and true signal to my subs. The sound comparison of head unit powered vs. amped with the ONYX 4.60 is totally awesome. It is like the difference between night and day. Additionally, I added Dynamat to the speaker install and everything is controlled by a Pioneer AVH-P3300BT head unit to deliver 120 clean, clear, crisp RMS watts to these components. There is nothing negative regarding this amps perfomance, but MB Quart could have left the red chicklet logo unilluminated, as this does throw off the beautiful gloss black appearance of the amp. That doesn't really matter though, as this amp is built to perform, appeasing the ears, not the eyes. For my subs, I have 2 10" Alpine SWS-1023's driven by the MB Quart REF 1.800. Everyone is amazed when they look inside my F-250 Crew Cab, as they are expecting to see a whole gamut of speakers and amps, but they are surprised to see that everything looks stock with the exception of the head unit! When everyone asks "How did you do it?" I just say Sonic! and I'm not talking about the drive-in either, LOL. Thanks SonicElectronix.com!

I have this amp running my Rockford fosgate power series component speakers. And they sound loud and clear! I have to turn the gain only half way up! Before the sound is piercing!

I was very skeptical about this amp because MB Quart used to be a great company until maxxsonics got ahold of it. All of mb quarts products are still good as long as you get a good batch. Anyways, this amp is absolutely amazing! It sounds beautiful powering my 4 Rockford Fosgate p152 coaxials in my jeep cheeokee Xj. It powers them perfectly and has rich mids, crisp highs and clean clear mid bass. Amazing bang for your buck! And goes beautifully with my RE Audio SEX10d4 and MB Quart ONX1.1000d. Looks great but the light just kills the nice glossy black look. These amps have a lot of setting to tune to your personal preference. Overall great product!

MB quart has done a great job with the Onyx line, and this amp is no exception, even though its not CEA compliant. The ratings are true, and from hooking it up to a friends speakers, i'm pretty sure it can put out 70+ if properly tuned on a good day.
My only gripes are that the angled terminals are kind of a pain to use once you mount the amp, and the 4AWG terminals are 4AWG, exactly, there is no extra room for wire in there, and the light blows the classy piano black scheme
