Quartorigo – Musical Rhapsody Meets Sublime Style
An astute electronics genius heralding from the unmistakable landscape of Macerata's countryside in Italy; Quartorigo lives by a philosophy that sees superb design the centre-point of refined technical expertise and innovation. Today Quartorigo leads the car audio industry with it's delectable aural solutions, stylistic flow and methodological ingenuity. Constantly redefining the benchmark for tomorrow's car audio and raising the bar to levels many companies simply will never achieve. Such is the Quartorigo way.

Humble Beginnings
A garage, a common passion, a crew of courageous enthusiasts. This is how most great musical adventures commence. However in this instance we're not talking guitars and microphones to arouse souls and blaze, but resistances, transistors, soldering and and most of all the limitless will to create something beautiful. During the eighties the high-end car audio market needed something new. Who'd have thought it would come from here, amongst Macerata's picturesque hills; dreamy car audio products set not only to become benchmarks, but also products able to please music lovers unquestionably.

Estremo Series - Where Power, Performance And Aesthetics Unite
When talking high-power audiophile grade performance, the go-to option is not always the ultra-expensive million channel behemoth the size of a table. Whether by choice or by force; we all have a fiscal and physical dimension we chose not to surpass. Just imagine though, if a company took one of its highly successful affordable designs and gave it a whole lot more power; to sate those guilty of the odd rush of blood to the head? Ironically this desire is exactly what Quartorigo engineers had in mind when they designed the superb Estremo range of amplifiers. Offering far more power than the range they're based upon; the Estremo series provide stellar sound quality along with power aplenty.

Design Ideologies
Estremo isn’t merely a name; it’s a statement of intent. It represents the pinnacle of Quartorigo’s three decades of car audio expertise, distilled into a line of amplifiers crafted for the uncompromising enthusiast. The Quartorigo engineers have taken the iconic DNA of the Fantasia series and pushed it beyond every limit.

Estremo Is Power
The term Estremo literally means extreme, signifying Quartorigo’s relentless quest to engineer the perfect instrument for sound reproduction, reflecting its drive to distill the essence of audio down to its purest form.

Retaining The Focus
Quartorigo focused on what truly matters to the dedicated audiophile. Unparalleled sonic purity with a commitment to absolute and unfiltered authenticity no matter how unvarnished. These amplifiers are designed for those willing to handle all types of recordings, even the most complex signals; without compromise or any kind of signal sweetening. To that end, Quartorigo has fine-tuned key design features by listening to the industry’s top installers. This ensures a cleaner installation and even more precise tuning capabilities, making the entire process as refined as the sound itself and empowering those audiophiles to achieve their ideal setup.

Music And Culture
When talking Italians you’re talking about a long and prestigious musical tradition which has its foundations firmly rooting in centuries of unique open theatre settings. Thus ratifying the bond between music and culture in a way few other societies are able too. This is where Quartorigo draws its inspiration from. It’s work is aimed at the pursuit of theater sound quality excellence, but inside your vehicle. From a concert hall to your vehicle’s seats, without loosing a single note and allowing you to live out the same emotions. It’s what makes Quartorigo a real conductor seated next to you as you commute.
