The Gen-X series has always been a DS18 staple with the public and been in countless system builds over the many years it was released.
We have completely redesigned the GEN-X series from the ground up to meet and audio enthusiasts high standards and complete their goals for the system of their dreams with great power, reliability, and efficiency.
The G1800.4D has a power rating of 4x300 watts RMS at 4 ohms 4x420 RMS at 2 ohms, 2x740 at 4 ohm bridge, and 3600 MAX at the two load it was designed for, giving you pure and clean power on demand.
This amp has the power to drive your speakers but also not take up much space because of the new compact design and technology that will keep your amp playing cool and loud.
