Onyx Amplifiers

MB Quart Onyx Q-Stasis

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.



MB Quart Onyx MOSFETS

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!
