It is barely imaginable that a fully grown class D amplifier works in this small housing, featuring six pairwise bridgeable outputs, each with 105 watts RMS per channel (at 2 Ω). A total of 630 Watts RMS are available. The compact dimensions are made possible by an elaborate 4-fold laminated board, which also effectively suppresses EMC interference due to the favorable topology - a must, especially for full-range Class D amplifiers.

EPS technology which prevents when connected to an OEM factory radio that nofunctions are impaired or error messages are written into the vehicle memory.

6 -fold laminated board effectively suppresses EMC interference due to the favorable topology.

Bridging amplifier channels enables more flexibility to handle the power.
