Tsunami Series

Avatar ATU-1000.4 – 4-channel broaband amplifier (AB class) with summary power 1000W.

Practical design, high power and considered filters make these models excellent decision for loud and high-quality car audio system.

Cast aluminium body has very good breaking resistanse. Also, heat resistance is very effective.

All the TSUNAMI monoblocs are bridgeable, that allows doubling the power to get desired maximum of sound pressure.
