T1000-4ad

The Rockford Fosgate T1000-4ad from the high-performance Power Series is a premium 4-channel amplifier featuring innovative Class AD technology and a total output of 1,000 watts RMS. Thanks to its combination of high efficiency, compact design, and tremendous power, this amplifier is ideal for high-end car audio systems.

Thanks to Constant Power technology, the T1000-4ad delivers 250 watts RMS per channel at 4, 2, and even 1 ohm. In bridge mode, up to 2 x 500 watts RMS are available. This gives the amplifier particularly flexible connection options for high-power speaker systems and subwoofers.

The built-in, adjustable high-pass and low-pass filters allow for precise adaptation to different speaker configurations. In addition, the Punch EQ tone control enables individual adjustment of the bass and treble ranges. The NOMAD protection circuit monitors the amplifier and provides reliable protection against overload, short circuits, and overheating.
