Infinity Kappa One 6

Kappa mono and full-range, multi-channel amplifiers deliver the efficiency and power you expect from Class D amplifiers and the performance you expect from Infinity. The comprehensive all new E.A.R.L terminal and power adapter (5-channel & mono block) enables easy installation and optimized performance.

For the 5-channel and mono amplifier models, the remote bass control allows the user to increase and decrease bass output independent of head unit tone controls. The industrial design not only provides an elegant look, but also enhances power dissipation to ensure long term reliability. Kappa amplifiers give you power to shape your car audio experience in new ways.
