Q-Stasis Pre-Amp Stage
MB Quart has always been an amplifier brand that's been attributed with quality audio. Onyx amplifiers, although priced for a more competitive market, still retain this quality. Onyx amps are an exceptional first step in putting together your car audio system. They're high powered amplifiers that use quality components to ensure that they sound great.
The 2013 Onyx amplifiers use a Q-Statis pre-amplifier stage. This addition is designed to keep incoming noise from source units at nearly immeasurable levels, improving sound quality. MB Quart also incorporates more new technology on the amplifiers with their new Fluid-Fets output devices. These are able to efficiently produce power and mimic the sound quality of high end home amplifiers.
On-Board Equalization
The multi-channel amplifiers are equipped with Class SQ topology. This circuitry, when matched alongside the Q-Stasis preamp stage is capable of outperforming standard Class A/B amplifiers in sonic accuracy and clarity.
MB Quart multi-channel amplifiers are an exceptional choice when building out your next car audio system. These amps sound great, perform just as well, and even look extremely stylish. Their black finish and illuminating logo help them look awesome when running in your vehicle. Pick yours up today!

MBQ 600
Great product for what I was trying to achieve. Used the amp in a 70 quart ice chest with (2) 6.5's and (1) 10" sub for my tournament baseball team. We rock the stands during pre-game and between innings!

An okay amp.
I bought this amp because I was on a budget. Now, 7 months later I have already replaced it. My amp made a horrible whining noise that was really loud and I could not fix it. Since switching to a Rockford amp this has gone away. The amp seems to do a little under its rated power. Probably around 65 rms, which isn't bad. If you're really on a budget pick this up or spend like $15 and get the MB Quart amp that puts out 100 watts x 4 channels. If you can save just a little more money look for a different amp. Also, this amp gets super hot. But, it never went into protect mode.

Good entry level 4ch amp
I have this amp in my 85 Delta 88 Royale Brougham pushing my high/mids which are a pair of Infinity Reference 3.5 in the dash and 6x9 in the rear. Good amp for the price that looks good in the trunk provided the power I wanted to my Infinity's. Have had no problems with it.

Clean amp..
I use this with rockford speakers and they sound very clean and it normally doesn't get hot.I advice you guys to make sure you tune your system so it wont sound distorted. I was going for an alpine but for 40 dollar less I got me this Mb quart that make the system sound clean.

Junk
amp arrived and I hooked it up and I got sweet, beautiful sound...for about an hour. It actually sounded very good powering my Pioneer TS-D1720c comps up front and running a Pioneer TS-W260S4 sub in the rear. After playing for about an hour it went into protect mode. I thought that it may have overheated but it was not hot to the touch. I checked the voltage to the amp and that was also good at 12v with the car idling. Since then the amp turned on, would play for 5-10 min, then go into protect again.

Good budget 4 channel
Good sq for the price. Way better than running your mids and highs off of a stereo. Not too flashy but has a nice look to it would recommend to someone looking for a good 4 channel amp but not trying to pay for $500 sound quality
