RN4.1400D - Designed & Engineered in the USA



We’ve adopted the most optimum Class D performance, reliability, and smaller footprint platform for the Rubicon Nano series amplifiers and present to you Rubicon Nano. At first glance, you’ll notice several key improvements; Rubicon Nano’s signal inputs, power/ground, and speaker connections are all relocated to the leading edge of the chassis for an easier, more attractive install. All pre-amp & crossover options are appropriately located on the top surface, making adjustments after installation conceivable. You might not notice embellishments to the circuit board, including increased power supply & output stage components & Monoblock bridging capability.

Are you using an original or factory radio? No problem, these amplifiers are equipped with an Automatic Hi-Level Signal Sensing Turn-On. There is no need to run a remote wire turn on; this amplifier will automatically detect the sound signal and turn on and off the amplifier. (Hi-Level Input only)
