We appreciate your interest in this Extensive HI-END, hand assembled, Car Audio amplifier imported from Italy.

The amplifier you are reviewing is a realization conceived by those who love the ultimate in sounds, and music as it was recorded for playback in your 12 volt environment(s).

What is the "Quartetto" amplifier?

"Quartetto" is the natural evolution of our top of the range "Quattro".

It was created to provide similar performance at a more accessible price, while remaining faithful to the philosophy of achieving maximum sound quality.

It is the result of over 1 year of research and development to build a car amplifier with exciting performance.

Also for "Quartetto" the collaboration with Roberto Tognon was decisive.
His experience and knowledge of music do contributed to the creation and development of this project.

The "Quartetto" adopts innovative circuit solutions with top quality components specific for audio use and will allow you to enjoy your favorite music without losing any detail or nuance.

The excellent measurements and the very high reliability in very compact dimensions make the "Quartetto" the new reference for car audio amplifiers in its price range.

From the assembly tech team: 
-This amplifier is designed to work only in a 12V DC electrical environment.
-Do not attempt to power it with AC or different voltages!
-Install the amplifier in a solid, flat and secure way that does not affect the driver's guidance or the ability for the device to become airborne.
-Do not place the device in very hot places (such as the engine compartment).
-Make sure that the installation location is not subjected to high humidity and/or splashes of water.
- Perform solid and safe connections, using only cables of adequate length, gauge and use oxygen free copper wires for power, ground and remote connections.
- It is absolutely essential to install a fuse of adequate value near of the battery.
- In the installation / removal and maintenance operations it is absolutely necessary to remove the fuse located near the battery before any connection or wires are removed to protect the safely of all individuals and electronics if the device is subjected to severe shocks that could visibly damage the chassis
-Let it be viewed by a certified professional installer.
-Keep the device clean and do not obstruct normal chassis ventilation,
-Do not use aggressive detergents for cleaning.
